Series U/ARP

The U/ARP series centrifugal fans are suited to convey air, even slightly dusty, at  temperatures of up to a maximum 80°C.
These fans are used in all the industrial applications requiring medium pressures and flow rates.
The thick steel sheet spiral casings are rimmed and welded. These fans have a base for the motor and the discharge angle can be adjusted in 45° steps by rotating either clockwise RD or counter-clockwise LG (see discharge direction table).
The steel sheet impellers have forward-curved blades. They are carefully balanced, both statically and dynamically, and are directly connected to the motor shaft.
The motors installed are asynchronous, three-phase or single-phase, 2 poles, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.
