Gates DraftGuard anti-rotation device for fan drive maintenance

The Gates DraftGuard anti-rotation device is designed to improve the safety of workers who are performing maintenance on fan drives.

The product eliminates back-drafting by securing the drive from spinning backwards during maintenance operations, as well as protecting the entire system from extreme shock loads during start-up, reducing unnecessary wear of the motor components, drive frame and potential belt breakage.

Benefits of the anti-rotation device include: prevents ‘locked out’ machinery from rotating; improves worker safety; prevents back drafting/windmilling of fans; eliminates hard starts during back drafting; avoids damage to belt drive, motor, bearings and structure during start-up; maintenance-free bearings, greased for life assembly; universal, versatile mounting plate; flange plate counter bore accommodates ½″ shaft protrusion without spacers; adapts to clockwise or counterclockwise operation easily; compact, thin design fits under most drive guards; disengages while fan drive is in operation, resulting in less wear to the drive or components; and bright yellow colour stands out for safety.
