Series U/CBThe U/CB series centrifugal fans are designed to take up clean or slightly dusty air at temperatures of up to a maximum 80°C.
These fans are used for ventilation and air conditioning plants and generally in industrial applications requiring high flow rates.
The strong steel sheet spiral casings are rimmed and welded. These fans 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 backward-curved blades have been carefully balanced, both statically and dynamically.
The motors installed are asynchronous, three-phase, B3, with IP55 protection, self-ventilated, designed for continuous service and are UNEL and IEC compliant.
