EC-Fan
This temperature-controlled fan from Prima Klima runs either absolutely quietly and hum-free at low power during the night phase or has an incredible performance of up to 1450m³/h (continuously adjustable!) during the day phase. This Prima Klima EC fan can be controlled by three parameters: minimum speed, desired temperature, and maximum speed. The minimum speed ensures that there is always negative pressure in the room at night so that the air always passes through an activated carbon filter. The desired temperature is chosen as needed, and the fan will continuously increase its speed from the minimum speed to achieve the desired temperature in the room. If a small activated carbon filter is used, it may be advisable to reduce the maximum speed to adapt the fan accordingly.
What are the advantages of a Prima Klima fan with EC technology? It is always more energy-efficient compared to similar AC fans, but especially when running at low speeds, up to one-third of the electricity costs are saved. This makes it cost-effective after a short running time. The efficiency of Prima Klima EC fans is unparalleled - more air is delivered with the same power consumption or a higher air pressure is generated at the same speed. Additionally, it is quieter than an AC fan due to its hum-free speed control.
The fans we distribute are equipped with EC motors from German production and are therefore always state-of-the-art technology.

What is an EC motor and how does it work? The two components of the motor, the stator (the stationary part of the motor with the electromagnets) and the rotor (the moving part, which in conventional AC motors also contains electromagnets) differ in that the rotor of the EC motor does not contain electromagnets that need to be supplied with power via brushes. Therefore, it is also called a brushless electric motor. The rotor contains permanent magnets that are moved by an electromagnetic field created by electromagnets on the stator. This is achieved by using a control electronic system that is built into the motor and allows speed control via a voltage of 0-10 volts. This voltage can be applied externally via climate controllers (temperature, humidity), or is already built-in with climate control at the fan housing for corresponding products.
