Enough Of The 'Windwilling'
The Draftguard anti-rotation device from Gates (Denver, CO) prevents belt-driven air-cooled heat exchanger (ACHE) fan drives from “windwilling” when they are idle. A free-spinning fan poses a safety hazard to maintenance workers and causes wear on belts, shafts, bearings, and attached equipment when the fan direction is reversed during start-up. The Draftguard uses a high-torque clutch to prevent backward fan rotation. This device mounts to either Taper-Lock or QD bushings used on ACHE belt drive systems.
