RS Nylon Molded Ring Fans

Developed specifically to deliver higher cooling performance at lower fan speeds, RS Molded Ring Fans also improve fuel economy.

The distinctive ringed design reduces cooling fan tip turbulence. Enclosing the fan blade circumference enhances engine cooling, and results in quieter operation. Manufactured from fiberglass-reinforced, heat-stabilized plastic materials, RS Molded Ring Fans retain their strength even at high operating temperatures.
