Series U/TMThe U/TM series centrifugal fans are designed to take up air, even very dusty and containing suspended materials, at temperatures of up to a maximum 80°C.
These fans are used in all the industrial plants requiring medium-to-high pressures, e.g. the pneumatic conveyance of granulates, shavings or trimmings.
The strong steel sheet spiral casings are rimmed and welded. These fans are provided with a base for the motor and the discharge angle can be adjusted in 45° steps by rotating either clockwise RD or counter-clockwise LG (see discharge direction table).
The welded steel sheet impellers with forward open blades have been carefully balanced, both statically and dynamically. Thanks to the special design these units can be used in all the circumstances where normal impellers might become obstructed.
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.
