(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, drive frame and potential belt breakage.
