High-pressure fan U/PB series

centrifugalventilationsteel

The U/PB series centrifugal fans are designed to take up and convey air, even if dusty, at temperatures of up to a maximum 80°C. These fans are used in industrial plants requiring medium-to-high pressures; furthermore they can also be used to convey solid materials, except strings, mixed with air. The strong steel sheet spiral casings are rimmed and welded. These fans also have a base for the motor and the discharge angle can be regulated in 45° steps by rotating either clockwise RD or counter-clockwise LG (see discharge direction table). The strong welded steel sheet impellers with high performance, backward-curved blades, have been carefully balanced both statically and dynamically. The motors installed are asynchronous, three-phase or single-phase, 2 or 4 poles, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.
