ductcommercialindustrial

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). Max. Volume: 15,500 m³ / h 4-pole, 230V / 400V / 50Hz / 60Hz with Fischbach EC controller IP54 / IP21 inverter / IP66 Adjustable speed via interface via 0-10 Volt Insulation class F (155 ° C) to VDE 0530th Motor protection IP 65 (electrical part) according to DIN 40050 / CE mark.
