Series U/APThe U/AP series 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 employed in all industrial plants where medium-to-high pressure values are required.
The steel sheet spiral casings are pressed and spot-welded or rimmed and welded and the outlet is fitted with a securing flange to make any pipeconnections easier. These fans can be directed in 45° steps by rotating either clockwise RD or counter-clockwise LG (see discharge direction table).
The spot-welded 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 poles, B5, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.
