Special features: Highly efficient duct fan, made of high-quality plastic (PP). Can be used for industrial and residential installations. With integrated mounting bracket for quick and easy fan attachment. High-pressure diagonal impeller with downstream stator for high air output. Modular design optimized in terms of flow and acoustics leads to very smooth running. Small space requirement due to compact dimensions. For direct installation between pipes, depending on the installation position for ventilation or exhaust. Pressure and suction side connection nozzles corresponding to the common standard pipe diameters. Quick and easy inspection and maintenance of the fan by opening the clamps. Protection class IP 44. AC motor: Speed controllable in 3 stages, optional speed controllable using phase control or transformer possible. Thermal overload protection as standard. Electrical connection via terminal box integrated in the housing. Robust motor with moisture protection and ball bearing, maintenance-free. Thermal class 130 (B). Installation instructions: Installation possible in any position. Electrical connection: External terminal box with cable entry grommet. Safety instructions: Only operate the fan with free intake or free exhaust if the impeller is protected against contact in accordance with DIN EN ISO 13857. To do this, attach the optional SGR protective grille.
