Series U/HCThe series U/HC centrifugal fans are designed to take up fumes or air, even slightly dusty, at temperatures of up to a maximum 80°C.
These fans are used for all domestic and industrial applications requiring the removal of large volumes of ducted air.
The outlet of the spot-welded steel sheet spiral casings are fitted with securing flanges. The special holes make it possible to orient the fan discharge angle in 45° steps by rotating either clockwise RD or counterclockwise LG (see discharge direction table).
The steel sheet impellers with forward curved “Sirocco”-type 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 or 4 poles, B5, self-ventilated, designed for continuous service and are UNEL and IEC compliant.
