Special features: Efficient radial tubular fan made from powder-coated steel sheet. Can be used for industrial and residential installation. Radial wheel with backward curved blades. Low noise and powerful. Small space requirement thanks to compact dimensions. For direct installation between pipes, depending on installation position for ventilation. Round connection supports tuned on the suction and pressure sides to standard pipes Mounting base available as accessory. Direction of feed: Direction of feed and rotation are indicated by arrows on the fan housing. Motor: External rotor-capacitor motor. Operating capacitor, ready for connection in the terminal box. Variable speed control Thermal overload protection (temperature sensor in motor winding) as standard. The overload protection automatically switches off the fan in case of overheating. Robust motor with ball-bearing, maintenance-free. Protection class IP X4 for installation in ventilation lines with at least 1 m pipe on suction and pressure side Mounting instructions: Can be installed in any position. Use optional ELR elastic cuffs to prevent vibration transfer to the pipe system. Electrical connection: Outer sleeve terminal box with cable entry grommet. Safety instructions: Do not operate the fan without suction or blow-out unless the contact protection of the impeller in accordance with DIN EN ISO 13857 is ensured. Attach optional SGR grille for this purpose.
