Draftguard® Anti-Rotation Device


Fan drives can rotate backwards when they are turned off, generally from air movement across the 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.

Markets/Applications
Ideal for any V-belt or synchronous belt drive where back-drafting or wind-milling is an issue or safety concern.

Features/Advantages

  • 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.
