Fan Belts: Synchronous and Cogged

Cogged V-belts and synchronous-drive fan belts are a low-investment way to reduce the inefficiencies in ventilation fans caused by belt slippage and bending resistance. 

GPG, Rocky Mountain Region, put both belts to the test on two different fans in Denver, Colorado. Researchers from the National Renewal Energy Laboratory (NREL) found significant energy savings with a simple payback of less than four years.
