Filter fans FL 3 with EC technology from häwa are designed very flat (only 6 mm) and offer in combination with the temperature control module an autonomous and continuous regulation of the rotational speed. The EC technology means, that the fan (after exceeding a minimum temperature value) only operates with part load and adjusts the rotational speed of the respective temperature inside the cabinet. Therefore, the electric power consumption and the noise level are reduced considerably since the fan only rarely has to operate under full load with maximum rotational speed. Furthermore, the life expectancy of the device is increased by less switching on and off processes. The application of the filter fan with EC technology is especially profitable where the power dissipation inside the cabinet varies strongly or the previously used filter fan has only very short run time.

Integrated fastening clips from V2A-spring steel allow an easy and quick snap-in installation with secure hold of the fan. An additional screw fastening is not necessary. With the serially foamed sealing the degree of protection IP 44 is achieved. Through the utilization of the filter mat G4 from häwa, even the degree of protection IP54 can be achieved. With two slots, changing the filter is very easy and quick. A coding tap prevents the wrong insertion of the front grid.
