Alternate Supplier #Draftguard Torque Arm
Draftguard Anti-Rotation Device Fan drives can rotate backwards when they are turned off, generally by reason of air movement across the fan blades. Draftguard anti-rotation device secures the drive from spinning backwards during maintenance operations as well as protects the entire system from extreme shock loads during start-up, causing unnecessary wear of the motor components and potential belt breakage.
Ideal for any V-belt or synchronous belt drive system where back-drafting or wind-milling is an issue or safety concern.
Designed with mounting holes for bushings including QD (E, F and J) and Taper-Lock (3020, 3525, 3535, 4030) commonly found on ACHE belt drive systems. Maintenance-free bearings greased-for-life assembly. Small investment to mitigate risk to employees and equipment.
