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. EC motor: Highly efficient EC internal rotor motor. HDR 10 EC to HDR 16 EC: three-stage. HDR 20 EC and HDR 25 EC: continuously variable speed. Thermal overload protection as standard. Robust motor with moisture protection and ball bearings, maintenance-free. Thermal class 130 (B). Installation instructions: Can be installed 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.Article: HDR 16 EC, delivery volume: 662 m3/h, speed: 2680 1/min, impeller type: diagonal, speed controllable: yes, reversibility: no, voltage type: alternating current, rated voltage: 230 V, mains frequency: 50 Hz / 60 Hz, rated power: 36.5 W / in opt. efficiency, INom: 0.31 A / in opt.
