Perma-Cool Turbo Flex Heavy-Duty Fan Clutches

Perma-Cool has developed a new clutch design concept that prevents hot spots for increased clutch life. Quad-grip is Perma-Cool's exclusive cross grid/groove design that causes the viscous fluid to flow in all lateral directions while rotating, preventing hot spot tracking. With more spiral-staggered fin design surface area, Perma-Cool Turbo Flex heavy-duty fan clutches grab huge bites of air for ultimate heat dissipation and cover most domestic applications for both reverse and standard rotation systems. For a cooler clutch with a longer bearing life and an increased fan power range, Perma-Cool Turbo Flex heavy-duty fan clutches are the best choice. Show Less
