Fan drives can rotate backwards when they are turned off, generally from 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.
Markets/Applications
Ideal for any V-belt or synchronous belt drive system where back-drafting or wind-milling is an issue or safety concern.
Features/Advantages
-
Designed with mounting holes for bushings including QD® (E, F and J) and Taper-Lock® (3020, 3525, 3535, 4030) commonly found on ACHE belt drive systems.
-
Maintenance-free bearings greased-for-life assembly.
-
Small investment to mitigate risk to employees and equipment.
