Constructions:
Drum of pressed sheet steel with one flange (PL) or with double flange AM AL ALc) bored for anchorage to walls or between pipings, complete with plate for supporting the control motor. Die-casted rotor in light alloy (sparkproof) with blades with winged profile, dynamically balanced. Assembled overhung on the motor’s shaft. The inclination of the rotor’s blades is adjustable when the fan is stopped from the types 710 up to 1400. The direction of the air is from the motor to the rotor (clockwise direction seen from the motor). It is always possible to invert the airflow, i.e. from the rotor to the motor, by inverting the motor’s rotation, this is done by disassembling the rotor and reassembling it overturned
