High quality switches and capacitors ensure long life and trouble-free operation. And if something goes wrong during delivery or installation the fan comes with a balancing kit. All these aspects are invisible for the client ‘s eye. Separating “the wheat from the chaff” is therefore only possible during daily operation. Nothing is more unpleasant than a ceiling fan that is unbalanced, makes a lot of noise or stops working entirely when in continuous operation. CasaFan devices are comprised of high-quality, tested components entirely. The motors are designed for continuous operation and have sufficient extra capacity. Only after many years, when a blade gets bent whi le mov ing house or the motor housing gets dented, it becomes apparent whether the manufacturer has a systematic replacement parts service. And whoever has tried to purchase a 3-speed pull-cord switch on its own, appreciates that we keep every Many ceiling fans may look very similar to the CasaFan models. Even so, identical appearance does not mean identical performance. In fact, the major aspects that account for the quality of a fan are invisible at the first glare. The heart of a fan is its motor. The materials used in the core and the windings af fect performance and thus the motor’s energy consumption. The windings must be tight and as even as possible. Important factors Your safety is our priority. Even when we are developing new models, we feed in our 38 years experience with ceiling fan products. Many small details that enhance the quality, durability and safety of the product are standard for us. That is why many of our CasaFan products carry the GS-tested safety mark (Geprüfte Sicherheit). Quality and Safety – Identical Appearance = Identical Quality? Over the past years ce i l ing fans have become increasingly popular - even in countries with a moderate climate. Ceiling fans not only create a pleasant living and working environment . They also prevent „stale air“, provide a fresh breeze and - the most important argument in times of high energy costs - they save heat ing costs. By means of this catalogue we try to pass on the entire experience we have gained over the past 38 years in an easy-to-understand form. Take some time to choose your fan, because besides shape and colour, there are other impor tant factors that will soon make a ceiling fan indispensable in your Have lots of fun selecting your fan! Best wishes from all of us at For over 130 years, ceiling fans with AC motors (Alternating Current) functioned more or less according to the same principle. A voltagecontrollable, multi-pole single-phase asynchronous motor with squirrel-cage rotor, which is equipped with an auxiliary winding for start-up, provides the required torque and speed. The external rotor motor is equipped with a stationary stator inside and a moving, rotating, outer part, the rotor. Although these types of motors are relatively inexpensive to produce, they do have some disadvantages. They are prone to electromagnetic resonance, which can be noticeable in the form of humming noises. This can be reduced by an optimal design of the motor and the use of high-quality raw materials. In addition, they cannot be controlled steplessly with the usual control methods, e.g. phase control or section control (comparable to electronic dimmers), without emitting loud buzzing noises; in living areas, possibly in the bedroom, this is an intolerable condition. However, in times of expensive energy, the biggest disadvantage of the AC motor is its low efficiency. Compared to an optimally designed EC/DC motor, it requires up to 3 times more electrical energy for the same air performance. Direct current or DC does not automatically mean energy-saving More than 25 years ago, CasaFan supplied ceiling fans for a project that were pure DC fans. The aim was to operate a fan directly on 12 V DC generated by a solar panel. In the project, which was funded by the World Bank, simple huts in Central Africa were equipped with a solar panel together with a battery and control electronics. The alternating current or AC motor - standard since more than 130 years home or of f ice. Here you can find the suitable model for every taste and every application. If you have any questions, your specialist dealer will be happy to help you. When choosing a product, be sure to look for quality. Starting with the balancing and synchronisation of a fan, through the design to the workmanship - all factors that are a guarantee for your satisfaction. When we include a fan in our catalogue, you can be sure that it meets the highest quality standards. Unlike many other manufacturers, who produce cheap goods for hardware stores and discounters, all CasaFan products are designed for long-term operation and are The aim was to improve the quality of life for the local population, that was cut off from the power supply infrastructure. Two energy-saving lights, a refrigerator, a television and a ceiling fan were part of the scope. Compared to the latest CasaFan products the ceiling fan from back then our first direct current (DC) ceiling fan was not particularly efficient when comparing the electrical power in relation to the volume flow (SV = service value of 1.9 to our modern ECO ceiling fans (EC/DC) of today. Today, a SV of 6-10 is standard for EC/DC fans. Commutation is crucial 14 years ago, CasaFan was the first ceiling fan manufacturer in Europe to launch an EC/DC ceiling fan. With the same airflow compared to the AC model ROYAL 132 with 69 watts, the electrical power of our first ECO model was 23.5 watts at that time and enabled a previously unimagined energy saving of over 60%. The success of this model confirmed our decision to focus more on the energy-saving EC/DC technology (EC: electronically commutated). In addition, the much smaller design of the EC/ DC motors enables completely new designs. Models like the Eco Genuino, without any visible motor fully integrated into the blade design, would be impossible with conventional AC motors. Our ECO fans work exclusively with Our smallest and most economical DC/EC motor. On the left the stator with the windings, in the middle the rotor as a permanent magnet. On the right, the ready-to-operate state. In addition to the statutory warranty, we provide a quality guarantee for up to 25 years on the motors of our ceiling fans! But even Through the CasaFan combination system, you can individually put together the unit that suits you best. The wood colour of the blades, the light, the housing - everything according to your personal taste and matching your furnishings. And if required, we have the perfect control unit for you - whether wireless remote control or wal l switch. The extensive range of accessories enables installation in almost any situation. Your decision for a CasaFan product allows you to have access to the best quality with the longest service life at reasonable prices. Compare for yourself! CasaFan Quality Warranty Endless Selection Priceperformance ratio after that, we keep all spare parts for your fan in stock. The motors of our units are designed for continuous operation and offer sufficient power reserves. A „cheap“ unit is often more expensive to repair or exchange than a high-quality brand product. DC/EC Motors - the Advantages: - state-of-the-art technology - energy-saving - almost noiseless - long-lasting - maintenance-free - 6 speed levels, subtly divided - compact design Smart Life App Many of our ceiling fans are now available with WiFi control via app for smartphones and tablets.

In times of growing responsibility for the environment, we, as the market leader in the specialised trade, consider it important to use pioneering energy-saving technologies. The new ECO models of the ECO GENUINO and ECO PALLAS series are extremely economical with 20 watts and consume only one third of the electrical power compared to most available AC fans! Still, with the same air delivery capacity and effective range! spare part in stock - from the switch to the motor - even for devices that we delivered 20 years ago. EC/DC motors, the most energy-saving type of a ceiling fan motor. These are also known as BLDC (brushless DC motors). As before, the ceiling fan is connected to 230 V~50 Hz alternating current. A voltage transformer built into the control unit generates the required DC voltage. The electronic commutation (EC) of the BLDC external rotor motor is decisive for the high efficiency. Here, the rotor is equipped with a permanent magnet; the stator is fixed and is equipped with the windings. The windings are three-phase. CasaFan uses sensor-controlled or sensorless motors, depending on the model. In the first case, with our sensorcontrolled motors, a hall sensor permanently reports the position of the rotor to the electronics. The electronics thus know the current position and which windings are how strongly to be powered, so that the desired direction of rotation and speed can be achieved. Our sensorless motors work purely according to electrical parameters. The electronics evaluate the inductance generated in the windings and control the voltage in the different windings depending on the value. 25 YEARS LIMITED MOTOR WARRANTY

I I Mounting of ceiling fans When installing ceiling fans, a few points have to be considered especially for safety reasons. First check the load-bearing capacity of the ceiling. The mounting must be able to support at least 4 times the weight of the fan. In rooms equipped with suspended wooden or plasterboard ceilings, a ceiling fan must never be screwed only to the plasterboard or wooden Fig. 4: Trimming support SST Fig. 5 Installation with trimming support SST Trimming support SST Solid ceiling (concrete) suspended ceiling subconstruction Fig. 1: Tensioning of a false ceiling Fig. 3: Non-permitted fastening Fig. 2: Screw connection with substructure Distances: A C B D Fig. 6: Minimum distances when installing ceiling fans in rooms When installing a ceiling fan, some minimum distances must be observed for safety reasons, but also to optimize the airflow. Figure 6 shows these distances: A: Distance to walls: should be at least 40 cm. B: Distance to slopes: at least 15 cm horizontally. C: Distance between blades and ceiling: at least 0.2 x fan Ø, except for extra-flat models. From a ceiling height of 3 m, „C“ should be at least 0.3 times, from 5 m 0.6 times and above 0.8 times the ceiling fan Ø. For rooms with low ceilings, always use our extra-flat models! D: Distance between lower edge of blade and floor: at least 2.3 m (mandatory in commercial and public areas according to EN 60335-2-80, recommended in private areas).

Screwing into the load-bearing substructure of the ceiling is preferable (Fig. 2). The ceiling mount of the fan with the suspended ceiling is braced against the fixed ceiling, usually made of concrete, with long screws and dowels (Fig. 1). For grid ceilings, which are common in offices, we recommend the lengthadjustable suspension bracket type SST (Fig. 4 and Fig. 5), which is available in many lengths. This ensures a safe and vibration-free suspension of all our ceiling fans. Mounting on roof and ceiling slopes From a room height of approx. 2.7 m or when mounting on roofs or sloping ceilings, we recommend using a longer ceiling rod. A ceiling fan always hangs vertically. Depending on the model, the suspension of our ceiling fans compensates for a tilt angle of the ceiling (Fig. 7, A). The maximum possible pitch per model can be found on pages 126 - 127. For higher roof pitches, an on-site auxiliary construction in the form of a wedge made of wood or metal (B) is used, which ultimately enables the fan to be mounted on a horizontal surface. To prevent the blade of the ceiling fan from hitting the pitch of the roof, a longer ceiling rod (accessories, see page 145) is required, which can easily be shortened by sawing it off to any intermediate size. The minimum distance (Fig. 6, dimension C) depending on the angle of the roof or ceiling slope is shown in the following table: On pages 126 - 127 you will find all total distances per model as supplied, as well as with the longer ceiling rods available as accessories. The rods also include a cable extension with patent plugs for easy electrical connection. Roof slope here e.g. Memory Almost all CasaFan ceiling fans are equipped with a memory function. A memory module is located in the receiver of the remote control. Do you exchange your current ceiling lamp for a fan with lighting? This is easily possible with the memory module. If a simple light switch was previously available for this purpose, you can continue to use it. The motor of the fan is switched to OFF, the light to ON by remote control. Now you can turn the lamp on or off as before when entering the room with your light switch. The memory module of the control unit „remembers“ the state before the voltage dropped (before the light switch was switched off) and restores it within 1.5 seconds. If necessary, the fan is turned on by the pull switch. The table on pages 126 and 127 shows you which models have this memory function. If you are unsure which control is compatible with your application, please contact your electrician. He will give you expert advice. Your new ceiling fan needs a power supply on the ceiling where it is to be mounted. Since installing additional cables at a later date is often very costly or simply not possible, we have designed all our fans so that they can be exchanged with an existing ceiling light. On pages 126 to 127 you will find the assignment of the connection diagrams to the respective models. Standard is a switched phase or continuous voltage. If you have a second phase on the ceiling that is switched via a (light) switch, you can use this to switch the lighting on and off separately and independently of the motor of your ceiling fan on many of our models. If you replace your existing switch with a tap changer or transformer, you can use this to control the motor speed additionally (wiring diagrams 7 and 8).

8 9 To determine the optimal ceiling fan for a room, you need to know the physical background and relationships. First, the goal for which ceiling fans are to be used is determined: If the aim is to improve comfort at high temperatures in summer, the purpose is summer ventilation with ceiling fans. Also during winter times you can benefit from our ceiling fans. Warm air rises and accumulates under the ceiling. That effect leads to major temperature differences between the ceiling and the effective living space. Hence, by means of winter ventilation warm air is brought down slowly to the occupied living area. In principle, there is nothing to be said against combining both objectives when using ceiling fans. The main difference is the respective air speed of both applications. People perceive air currents completely different depending on the ambient temperature, humidity and air speed. If the environment is cooler, the same air flow in winter is perceived as unpleasant, draughty and may even promote illness. In summer, when temperatures are high, it is refreshing and beneficial. What people perceive as pleasant is what experts call comfort or thermal comfort. The American standard ASHRAE-55 describes 6 criteria that have an impact on a person‘s personal comfort range of temperature: ■ Physical activity: Heavy physical work requires more cooling of the person than sitting or lying down quietly in order to keep the temperature balance in equilibrium. ■ Clothing: In thin and short-sleeved clothing, the body‘s heat loss is disproportionately higher than in thick clothing that covers the entire body. Fig. 8: When positioning ceiling fans, it should be ensured that the fan blades do not pass through a downward-facing luminaire. This leads to unpleasantly irritating stroboscopic effects. Fig. 9: Especially at workplaces, the flickering of ceiling fan blades running through the lighting is disturbing. This should be taken into account during planning. ■ Heat radiation from objects in the environment: A person standing next to a hot injection moulding machine needs much more cooling in the same environment than without this machine. ■ The ambient temperature: At high ambient temperatures, the cooling requirement of humans is higher than at low temperatures in order to remain in thermal equilibrium. ■ The air velocity in the occupied zone: In draughty rooms, the human body loses temperature very quickly. ■ The relative humidity: The evaporative cooling of the body works much faster at low room humidity than at high room humidity, because dry air can absorb more water vapour than humid air. Why does moving air cool the human body even though it hardly lowers the room temperature? The movement of air extracts heat energy from the body by evaporating moisture on the skin, similar to driving fast in a car with the windows open. Even if the skin appears dry, there is a micro-fine film of moisture in the pores. At higher temperatures, the human organism promotes this natural cooling by releasing fluid on the surface of the skin through the sweat glands. This effect is easy to understand when you blow on your wet hand. The energy required for evapoCooling effect °C (°K) 1 2 3 4 0.5 1.0 1.5 0,0 0 2.0 Air velocity m/s 5 Diagram 1: Air flow velocity and cooling on the human body. T C L 3,8 x 4,3 m 6,20 x 4,5 m 6,20 x 4,5 m In a living/dining room of approx. 28 m², the thermal comfort is to be improved in summer by means of ceiling fans. This can be achieved with a 132 cm diameter ceiling fan in the seating area of the living corner. The area of the main and secondary air flow effectively covers an area of approx. 8 m². But even beyond this, there is still an air movement that can be perceived as pleasant, but according to Diagram 1 on page 8 can no longer be used for summer cooling. If both the seating area and the dining area are to be provided with generous cooling at higher temperatures, two units of size 103 cm can be used instead of one ceiling fan of size 132 cm (Fig. 10) (Fig. 11). Fig. 10: Summer ventilation in the living/dining room with a ceiling fan Ø 132 cm Fig. 11: Separate living/dining area with two ceiling fans, each Ø 103 cm Fig. 13: Summer ventilation in a room with 2.5 m ceiling height with the low profile model Eco Plano II 132 ration is thereby drawn from the body surface by heat conduction and cools it down. This cooling of the body is shown in diagram 1 (bottom left). Using the software tool „CBE Thermal Comfort Tool“ from Berkeley University of California, the following diagrams were created to show the comfort range. With a ceiling fan in forward rotation, a distinction is made between the main air flow and the secondary air flow. The vertical main air stream forms a circle with approx. 1.3 times the diameter of the ceiling fan (B). The maximum air velocity in the main air stream at head/shoulder height in a room with 3 m ceiling height is listed in the tables on pages 122 to 125. 20 22 24 26 28 30 32 34 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 1.1 1.2 Operative Temperature [ ˚C ] Relative Air Speed [ m/s ] 20 22 24 26 28 30 32 34 0,0 0,1 0,2 0,3 0,4 0,5 0,6 0,7 0,8 0,9 1,0 1,1 1,2 Operative Temperature [ ˚C ] Relative Air Speed [ m/s ] The secondary airflow (C) is an area where the air velocity decreases outwards due to directional deflection and turbulence. The flow is diagonal to horizontal. The area of the secondary air flow is a circular area with approx. 2.4 times the diameter of the fan. These areas are the basis for the design of ceiling fans for summer ventilation in any room. Under certain circumstances it may make sense to choose the next larger model when selecting the size, if the structural conditions permit. This is because a slightly larger dimensioned ceiling fan can run more slowly than a smaller model to deliver the same amount of The comfort range shows which air speeds are perceived as comfortable at which room temperatures. Diagram 2 (page 8) shows a central control of the speed where the users of the room have no influence on the control. This applies, for example, in schools or in open-plan offices where several ceiling fans are controlled centrally in the same way. Diagram 3 (page 8) is valid for applications Diagrams 2 and 3: Thermal comfort in relation to air velocity Ceiling fan Ø Fig. 10: Main and auxiliary airflow Fig. 12: Summer ventilation in the bedroom Addition/amendment to the installation In addition to avoiding mounting on vibrating surfaces, it is essential to ensure that no objects reach into the radius of the ceiling fan‘s blades (cables, lights, cabinet doors, etc.). Always use the screws and dowels suitable for your ceiling type for mounting. The avoidance of light effects is shown in fig. 8 and 9. Fundamentals of thermal comfort Design example summer ventilation A sleep timer that switches off the ceiling fan after a preset time is useful in the bedroom. This way, you can use pleasant cooling to fall asleep and do not expose yourself to the risk of health consequences from a strong draught that lasts all night. A sleep timer is included as standard in many of our ECO fans and is operated via the fan‘s remote control. air. This provides reserves that can be helpful in the case of very high temperatures. where the users can individually control the fans themselves by using the remote control or wall control. The air speed is unlimited here, as the users can adjust the air speed to their needs at any time with their „personal control“. Air ows with ceiling fans in summer operation The respective arrangement ensures good cooling through sufficient air movement in both areas. Ceiling fans in bedrooms Special attention should be paid to ceiling fans in the bedroom (Fig. 12). Especially during summer times, people tend to choose a higher air speed when going to bed. The body is sweaty, one is lightly clothed and is quickly cooled down pleasantly by the strong evaporation of sweat. If you fall asleep during this phase and the ceiling fan runs at high speed all night, there is a risk of damage to your health. A stiff neck or even a cold can be the result! Therefore, it is important to choose the speed of the fan so that the draught is only a faint breeze, depending on personal feeling ≤ 0.1 m/s). All our CasaFan ECO fans offer very low speeds for such cases, which do not cause any health consequences even for sensitive people.

10 11 Every ceiling fan that is designed for cooling in summer, in principle, can also be used for heat recirculation in winter. However, it is important to be able to generate an air flow that is as slow as possible. Due to the slower and draught-free flow, it can take up to 15 minutes to equalise the temperatures, depending on the area. 6,20 x 4,5 m A B *without air movement, air exchange and corresponding time period Fig. 15: Running backwards in high rooms, it remains cold underfoot Fig. 16: Forward running, the warm air reaches the ground Heated air has a lower specific weight than cold air. Following the laws of physics, it rises and accumulates under the ceiling of the room. This phenomenon is familiar to anyone who has ever stood on a ladder in a heated room in winter and carried out work on the ceiling. This causes a considerable temperature difference between the ceiling and the floor. The higher the room, the greater the difference. This enormous „heat reserve“ is conducted back into the occupied area without draughts by a ceiling fan with appropriate blade prof i l ing. Wi thout addi t ional heat ing, the temperature at floor level is increased significantly. Thus the device pays for itself within 2 to 3 heating periods!

Relatively low investments are offset by high benefits in terms of improved thermal comfort for teaching staff and students. In a 9 x 7 m classroom with a ceiling height of 3.20 m, thermal comfort is to be improved. The designer wants to use the Eco Neo III model with a size of 132 cm. According to Fig. 10 on page Wall control FB-FNK ECO Hotel for central control L Ceiling fans also create more comfort for employees in offices and meeting rooms in summer, when temperatures are higher. In Central Europe, temperate climate zones, ceiling fans are the cost-effective choice both in terms of purchase, but much more importantly in terms of follow-up energy costs. The design is based on the effective area with 2.4 times the diameter of the fan (Fig. 10, page 9). What is important here is the individual control of the ceiling fans by remote control or wall remote control or wall control, as every person perceives moving air differently. Ceiling fans for heat recirculation in winter Example: In a room 3 metres high, the temperature at floor level is 18°C. The temperature at the ceiling is calculated as follows: 18 x (1+(0,115x3)) = 24,21 °C In our example, the temperature difference is more than 6 °C*. A lot of wasted heating costs. automatic. This is because the thermostats of the radiators recognise the higher temperature and switch to heating mode later. If you consider that, according to a rule of thumb, a 1 °C higher room temperature corresponds to about 6% more heating costs, a lot of money can be saved with little effort. The t empe ra t u re d i f f e rence be t ween ce i l i ng and f l o o r can be ca l cu l a t ed using the fol lowing simpl i f ied formula*: Air ows with ceiling fans in winter In contrast to summer ventilation, a much lower air velocity of max. 0.1 m/s. at the body is pursued in winter ventilation, in order to avoid a cooling effect. In rooms with a ceiling height of up to 2.6 m, the ceiling fan runs optimally backwards for this purpose, i.e. it pushes the air towards the ceiling (Fig. 14). This flows down the ceiling along the walls to the floor and is sucked in again by the negative pressure under the fan and conveyed upwards. Since the air velocity at the fan on the suction side is much lower than on the pressure side, the air movement in the occupied zone is hardly perceptible. If the room is higher than 2.6 m, a ceiling fan should be operated forward, i.e. conveying the air downwards, even in winter. Otherwise, due to the natural buoyancy of the warm air, there is a danger in reverse operation, so it will not reach the floor and will flow back upwards towards the ceiling (Fig. 15). The room then remains cold underfoot and the desired effect is not achieved. Decisive for the heat recirculation in the forward direction (Fig. 16) in high rooms is the fine adjustment of the speed and thus of the air velocity. Our ECO ceiling fans have also been specially designed for this purDesign of ceiling fans for heat recirculation in winter The highest air velocity (Fig. 17) also prevails during heat recirculation with ceiling fans in winter directly under the fan‘s blade radius (A). The effective area, i.e. the surface area for heat recirculation in winter, is 4.5 times the diameter of the fan (B), which is considerably larger than the effective area for summer ventilation. Especially in high rooms , such as an attic studio, with e.g. a stove, the warm air from the heat source rises directly upwards under the ceiling and gathers there. For the users of the room, only the radiant heat of the stove arrives in its direct vicinity. Most of the heat emitted by the stove rises upwards to the ceiling as warm air and remains unused. tion, etc. A lot of heating energy is wasted here. The heat „stands“ under the ceiling. Fig. 13: Thermal layers in a heated, high ceilinged room*. pose. All these models have 6 speed levels, a very low lowest level and are subtly graduated. This means that even in winter, when people are very sensitive to draughts, the best air speed can always be selected. The correct use of a ceiling fan can save enormous heating costs. Design example ceiling fans in schools ceiling fans should be arranged at 2.7 m. The distance between the ceiling and the fan is then calculated from the dimensions table on page 126. From the dimension table on page 126, this results in the use of a 60 cm ceiling rod that is shortened by (810 mm - 500 mm) 310 mm. A central wall control FB-FNK ECO Hotel A #86200 (page 133), which is mounted on the wall near the teacher‘s desk, is used to control the fans together. Alternatively, a version of the fans with 0-10 VDC interface is used, which can be controlled in speed and running direction via the building management system or the wired wall potentiometer POT-R 0-10V #85251 from page 133.

These circular areas are distributed accordingly on the adjacent floor plan. The distance ceiling - sash should be at least 0.3 x fan Ø, i.e. 0.396 m, according to Fig. 6 on page 7. For reasons of appearance, the planner decides that the blades of the FB-FNK ECO Hotel wall control - the hotel guests won‘t take it with them Design example of ceiling fans in offices In many hotel rooms, they are now a well-established team: the ventilation system and the ceiling fan. The ventilation system ensures that stale air is exchanged for fresh air and transports any moisture to the outside to prevent damage to the building fabric. A ceiling fan improves the thermal comfort of the guest at higher temperatures. And quite incidentally, a ceiling fan with or without a light can be a very decorative furnishing item in a hotel room. Here, too, the low consumption and the relatively low acquisition costs favour the use of ceiling fans. Design example hotel room L

At that time it cost $22.50, representing about one fifth of the average monthly income. The blade diameter was 410 mm. The primary use of fans is to cool people during the summer heat. Even in ancient Egypt, fan bearers were a sign of a pleasant and active life. Small fans that were operated by a wind-up spring mechanism could already be found in the 18th century. Thanks to an invention by the English naturalist Stephen Hales, fans moved large quantities of air. On ships or in industrial production, among other places, they sucked in the air from outside and conveyed fresh air into the interior. For a long time, fans were driven by muscle power, later by fuels such as kerosene or steam engines with idler pulleys and drive belts. The first ceiling fans appeared in the United States in 1860. At the beginning of the Industrial Revolution, workers sweated in steampowered factories and were grateful for cooling provided by these early, two-bladed ceiling fans: The air flow reduces heat build-up on the human skin sur face, which creates a cooling effect. In 1882, the German-American Philip Diehl, who worked as a technician for the Singer Company, fitted an electric motor with an impeller and mounted the construction on the ceiling, which was much more space-saving. Already by the turn of the century, many proved their smoothness and energy efficiency. In the “Golden Twenties” there was hardly a bar, a restaurant, a drugstore, grocery store or a factory that did not use this new miracle of technology for cooling. With the Great Depression and its consequences for the population, ceiling fans went completely out of fashion. Within a short time air conditioning units came to dominate the American market in spite of their enormous power requirements; electricity from fossil fuels like oil and coal was cheap and ceiling fans were only for those with nostalgia. Only a few US manufacturers still produced ceiling fans. This was the opportunity that some Far Eastern manufacturers grasped. They were low priced and had sufficient experience in the field, because in many countries with tropical climates ceiling fans continued to be a product that was well-liked and in frequent use – especially where air conditioners did not succeed among the general population because of their price. Ceiling fans experienced a renaissance at the end of the 70s as a result of the oil crisis and rising electricity costs. Suddenly in the USA, the low priced and, compared to air conditioning units, power-saving ceiling fans became attractive again. factories in the USA, as well as upper class households, were already equipped with this novel, cooling marvel. For the first electrical table fan, the American electrical engineer Schyler Skaats Wheeler received the prestigious John Scott Award in 1904 for outstanding achievements in increasing living comfort and quality of life. The demand for small fans increased, so that European companies such as AEG also brought the first of their own devices onto the market. Later, the developed ceiling fans were fitted with four rather than two blades, which imA real run on the traditional product set in and helped many newly founded US manufactures to flourish. Unlike in the first decade of the century, when every part was “Made in the USA”, many components of this new generation of devices came from Asia, making the price of even high-quality products affordable for mass market consumers. In Central European countries with a temperate climate, the ceiling fan remained a luxury product for the few hot summer months. In warmer countries such as Spain, Greece, the south of France and especially in Italy, it quickly found new friends as a cooling lifestyle product and conquered the mass market.
