Series U/MPR

The U/MPR series centrifugal fans are designed to convey air, even if dusty, at  temperatures of up to a maximum 80°C.
They are used in all the industrial applications requiring medium-to-high pressures and low noise.
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 spot-welded 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 poles, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.
