DOSPEL domestic fans are universal. They are widely used for the ventilation of bathrooms, kitchens, toilets, as well as offices, houses and flats. There are five typical sizes of fans produced for ventilation ducts, diameters being 100, 120, 125, 150, 200 mm. Fans castings are made of high quality ABS plastic with an antistatic additive, which prevents dust accumulating on the casting. Most of the models are manufactured with IP X4 protection class. Motors with ball and slide bearing are used in Dospel fans. A motor with ball bearing extends the working life of the fan, reduces the noise and can be installed at any desired angle. Fans with slide bearing can only be installed in a vertical postion (either within or on a wall).
