Freewheeling Impeller

Freewheeling impeller for AHU with backward curved impellers made of aluminum and 100% adjustable Disc-Rotor-Motor/EC Disc-Rotor-Motor. The particular curvature provides a high power density and simultaneously low running noise. The impellers consist of riveted or welded aluminum wheels and have a flange for direct mounting. The FLRE/FLRE-EC, FMB/FMB-EC and FMBT Series have a mounting frame made of stable steel structure, with a fixed axle and rubber-metal connections (vibration) for smooth running. The housings consist of a robust frame design (aluminum) with 40mm cladding (insulation).
