High performance race fans designed from the ground up utilizing cutting edge technology and materials.
Race-Fan fans feature a universal center hub made from 6061-T6 Aluminum and composite blades for a significant decrease in weight over traditional steel fans.
The blades are manufactured using extremely durable high-impact and high-temperature fiber reinforced Zytel®. On the rare occasion that a blade does become damaged due to a heavy impact etc... the blade can easily be replaced without having to scrap the whole fan!
Another feature that Race-Fan fans provide, is custom cooling configurations for varying weather conditions. Every one of our fans can be configured in the following layouts:
2-Blade
3-Blade
4-Blade
6-Blade
Universal hub fits all blade size.  5/16" mounting holes.
