They have been developed for conveying the dry air of maximum temperature +40°C, of dustiness not exceeding 0,3 g/m³, without viscous impurities, aggressive compounds or substances causing explosion risk. The series of fans consists of four sizes of subsequent connection diameters 160, 200, 250, 315 mm. Structure The fan consists of cylindrical aluminium housing, with a radial impeller inside and a motor. The fan housing is protected by a polyester-glass composite. The outlet is directed downwards to the roof. The fan has to be installed on a roof base by means of a fl ange, fi xed to the inlet ferrule. It is recommended to install the fan on a sound absorbing roof base type TPD-N or TPDC-N, eventually on typical bases type BI or BII. On demand we off er speed governors type RP for a stepless adjustment of the rotational speed. As standard the fans are manufactured in bright-grey colouring. Roof fans
