Multi-Wing 610 mm 9-blade axial fan

Multi-Wing axial fan impeller, a complete hub-and-blade fan that moves large volumes of air at low pressure.

• Fits motor-driven cooling and ventilation fans, where the keyed hub mounts directly on the motor or fan shaft.
• Typical uses are HVAC air handlers and condensers, air-cooled heat exchangers, cooling towers, switchroom and plant ventilation, and radiator-style cooling.
• Nine blades, 610 mm (24") diameter, set at 37.5° pitch. Pitch sets the airflow and the power the fan draws, so match it to the original duty.
• Statically balanced to G6.3 at 960 RPM, which suggests a slow-speed motor such as a 6-pole 50 Hz.
• Cast aluminium hub with a keyed bore, held to the bush by small screws.
• Supplied as a complete assembly, so it can be used as a spare or as a direct replacement for the same Multi-Wing fan.
