• 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

Construction

• Designed with mounting holes for bushings including Taper-Lock® (3020, 3525, 3535, 4030) and QD® (E, F and J) commonly found on ACHE belt drive systems

Advantages

• Maintenance-free bearings greased-for-life assembly
• Small investment to mitigate risk to employees and equipment
