Draftguard® is an anti-rotation device typically used to stop ACHE fans from rotating backwards. Reverse rotation can strain the motor system during start up and pose a safety hazard to maintenance workers; eliminating reverse rotation can improve safety and reduce maintenance.
While Draftguard has typically been applied to ACHE fans, it can be used in other applications to limit rotation to a single direction. Draftguard can be mounted to the following bushings:
- 3020, 3525, 3535, and 4030 (TL style)
- E, F, and J (QD style)
A locking ring is also available to mount Draftguard in cases where it can not be mounted directly to the bushing.
