Centrifugal tube fan 258W, 1,370m³/h, IPX4 - Duct fan 1370m³/h ERR 31/1 – Maico – 0080.0278 – 4012799802785: Centrifugal tube fan 258W, 1,370m³/h, IPX4 ERR 31/1, housing material=steel, treated, air volume unloaded=1370 m³/h, connection voltage=230 V, DC motor=no, protection class (IP)=IPX4, length= 295 mm, diameter of the housing = 450 mm, radial impellers with backward curved blades. Connection pieces on the suction and pressure sides, for direct installation in ventilation pipes. Mounting foot available as an accessory. Conveying direction: The conveying and rotation directions are marked 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 as standard. Robust motor with ball bearings, maintenance-free. Protection class IP X4 when installed in ventilation ducts with at least 1 m pipe on the suction and pressure sides. Installation instructions: Installation possible in any position. To avoid vibration transmission to the pipe system, use elastic sleeves ELR. Electrical connection: External terminal box with cable entry grommet. Safety instructions: Only use the fan with free suction or blow-out if the impeller is protected against contact in accordance with DIN EN ISO 13857. To do this, attach the SGR protective grille.
