Heavy Duty Fan Clutches

• Exclusive staggered fin design has 60% more surface area for maximum heat dissipation
• Quadra-Grip^TM grid design prevents hot spots which shorten clutch life
• Thermal and non-thermal models offered
• Available in standard and reverse rotation configurations

A new concept in clutch design prevents hot spots which can cause shortened clutch life. We call this Quadra-Grip^TM, which is an exclusive cross grid/groove design on each face of the internal parts on our clutches. While rotating, Quadra-Grip^TM causes the viscous fluid to flow in all lateral directions preventing hot spot tracking. The result is a cooler clutch, longer bearing life and an increased fan power range.

Our fan clutches have more surface area with the exclusive new spiral-staggered fin design. This fin grabs larger bites of air for maximum heat dissipation. Universal fan clutch part numbers 25100 and 25200 cover over 90% of all domestic applications and fit both standard and reverse rotation systems. US patent 4,899,860.
