Reverse duct fans, type: KWR
Made in a standard way as K type fans. The possibility of bidirectional operation while maintaining equal working performance (suction or blowing) is its most distinctive feature.
Designed o pump air and other chemically inert media.
Standard Configuration:
- Diameter range: 400 to 1000 mm
- Capacity range: 5,140 to 50,200 m3/h
- Available motor capacity: 0.25 to 7.5 kW
Motors: asynchronous, closed in a casing made of cast aluminium or cast iron with maintenance-free bearings; single or three-phase, IP 55
Standard operating temperature range: -20 do +40°C
Fan casing: perfectly round, made of steel sheet, flanges rolled from the casing wall, protected against corrosion by powder painting or galvanization.
Used rotors: highly efficient with profiled blades made of very durable and light plastic (PPG - glass fibre reinforced polypropylene), aluminium die-cast hubs. Low weight of the rotor and its balance of G6.3 class extends the life of motor bearings and translates into low moment of inertia in the rotor, which can reduce the switching time of reverse systems.
Optional fittings:
- Fans equipped with an inlet or outlet grid.
- Motors: IP56 or IP66, insulation class H, dry or wet tropics.
