Special features: Efficient radial duct fan made of powder-coated sheet steel. Can be used for industrial and residential installations. Radial impeller with backward-curved blades. Low noise and high pressure. Small space requirement due to compact dimensions. For direct installation between pipes, depending on the installation position for ventilation or exhaust. Round connection pieces on the suction and pressure sides matched to standard pipes. Mounting foot available as an accessory. Air flow direction: Air flow and direction of rotation are indicated by arrows on the fan housing. Motor: External rotor capacitor motor. Operating capacitor ready for connection in the terminal box. Speed controllable. Thermal overload protection (temperature sensor in motor winding) as standard. The overload protection switches the fan off automatically if it overheats. Robust motor with ball bearing, maintenance-free. Protection class IP X4 when installed in ventilation ducts with at least 1 m of pipe on the suction and pressure side. Installation instructions: Installation possible in any position. Use optional elastic ELR sleeves to avoid vibration transmission to the pipe system. Electrical connection: External terminal box with cable entry grommet. Safety instructions: Only operate the fan with free intake or exhaust if the impeller is protected against contact in accordance with DIN EN ISO 13857. To do this, attach the optional SGR protective grille.
