DRAFTGUARD LOCKING RING

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.

• 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.
