Series U/APF

The U/APF series centrifugal fans are designed to convey air, even if dusty, at  temperatures of up to a maximum 80°C.
These high performance, high pressure fans are used in exhaust, drying and pressurization systems.
The strong steel sheet spiral casings are rimmed, welded and 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 forward-curved blades have been perfectly balanced both statically and dynamically, and are connected directly to the motor shaft.
The motors installed are asynchronous three-phase, 2 poles, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.
