Series U/RFThe U/RF series centrifugal fans are designed to take up air, both clean and dusty, at temperatures of up to a maximum 80°C.
These fans are used in all industrial applications requiring medium-to-high pressures; furthermore they can also be used as pneumatic conveyors of granular, but not stringy, materials.
The strong steel sheet spiral casings are rimmed and welded. Special holes make it possible to direct the fan discharge angle in 45° steps by rotating either clockwise RD or counter-clockwise LG (see discharge direction table).
The welded steel sheet impellers with forward open blades have been carefully balanced, both statically and dynamically, and are connected directly to the motor shaft.
The motors installed are asynchronous, three-phase or single-phase, 2 poles, B5, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.
