Where we are

Series U/AR

Serie U/AR The U/AR series centrifugal fans are designed to convey both fumes and air, even slightly dusty, at  temperatures of up to a maximum 80C. These fans are used for ventilation and conditioning, and generally when systems require high flow rates.
The steel sheet spiral casings are of adequately thickness and have been carefully rimmed and welded. These fans have 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 have high performance forward-curved blades. Each impeller has been perfectly balanced, both statically and dynamically, and is directly connected to the motor shaft.
The motors installed are asynchronous, three-phase or single-phase, B3, self-ventilated, with IP55 protection, designed for continuous service and are UNEL and IEC compliant.
