Where we are

Series U/APR

Series U/APR The U/APR series centrifugal fans are designed to convey air, even very dusty, at  temperatures of up to a maximum 80C.
They are used in all the industrial plants requiring very high pressures. Furthermore these fans can also be used to convey air containing granular, but not stringy, material.
The strong steel sheet spiral casings are rimmed and are reinforced with steel profiles. 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 welded steel sheet impellers with radial blades have been perfectly 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, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.
