Where we are

Series U/PBM

Series U/PBM The U/PBM series centrifugal fans are designed to take up air, even if dusty, at  temperatures of up to a maximum 80°C.
They are generally used in the industrial plants requiring medium-to-high pressure; 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 motor support base and the discharge angle can be regulated in 45° steps by rotating either clockwise RD or counter-clockwise LG (see discharge direction table).
The steel sheet impellers with high performance, backward-curved blades, have been 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.
