Roof exhaust fans of the RF/EC type are designed for ventilating rooms with a low degree or air pollution. The fans are used in exhaust systems in houses, supermarkets, industrial rooms, shops, warehouses, garages, parking facilities and outbuildings.


In RF/EC fans, there are used motors with impellers having backwards curved blades: in sizes 125, 160 and 200 - made of plastic, in size 250 - made of aluminum sheet. The enclosure is made of aluminum-zinc sheet, canopy made of laminate.

Fans are equipped with a connector for ventilation duct. They are adapted for use in vertical position, for installation on flat roofs, after applying an appropriate roof mounting base can be installed on sloped roofs.

Electric motor

Highly efficient motors with integrated EC technology, which, thanks to the reduced demand for electricity (lower CO2 emissions), minimize operation costs.

The fan motor is equipped with a 0-10VDC control input that allows variable rotation speed control. Insulation class - B (models from 125 to 250 / L), F (models from 250 / H to 500). Protection degree- IP44 (models from 125 to 250 / L), IP54 (models from 250 / H do 500). Power supply - single-phase 230V, 50Hz or 400V, depending on the model.
