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, which cause unnecessary wear of motor components.

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