Farm building fan KWR series

for air circulationaxial

-The fan can operate in two directions of rotation while maintaining the same operational performance, namely blowing or suction. -Fans designed to create flow of air and other chemically inert agents. -Operating temperature -20 ÷ +55°C -Ingress protection IP55 FAN HOUSING Fan housing: with a perfectly round shape, made of steel sheet, flanges rolled from the housing, protected against corrosion by powder coating or galvanizing. MOTOR Motors: asynchronous, placed in a closed cast-aluminum or cast-iron housing, equipped with maintenance-free bearings; 1- or 3-phase type. IMPELLER Our impellers: high efficiency impellers, with profiled blades, made from a durable and lightweight plastic material – PPG (polypropylene reinforced with fiberglass), pressure-cast aluminum hub. The low weight of the rotor and its dynamic balance in G 6.3 class extends the life of the motor bearings. ADDITIONAL OPTIONS Impellers: equipped with aluminum or PAG (fiberglass-reinforced polyamide) blades. Motors: IP 56, IP 66, H-insulation class, two-speed motors, dry or damp environment, adapted for use with an inverter or to operate in temperatures -40 ÷ +60°C. Fan housing: made of stainless steel or aluminium. Also available: fans resistant to aggressive chemical agents.
