Roof fan-RFV-EC


RFV / EC roof exhaust fans are intended for the ventilation of rooms with low air pollution.

They are used in exhaust systems of flats, supermarkets, industrial halls, workshops, warehouses, toilets, garages, car parks and farm buildings.


The RFV / EC fans use rotors with backward inclined blades made of plastic. The fan is made of galvanised sheet steel.

Fans suitable for working in a vertical position are suitable for installation on flat roofs. After using suitable roof supports, they can be installed on sloping roofs.
