The system includes 3 feet of 3" diameter inlet hose (to the blower), 4 feet of 1 1/2" diameter outlet hose (from the blower to the helmet), a 12 volt 235 CFM blower, and a HEPA-4 air filter to ensure the driver's air is clean and virtually particle free down to 4 microns. Requires a ported helmet (sold separately).

The blower measures 5 3/4" long overall and draws 4.3 amps. Hose and fitting colors may vary from photo.

Replacement HEPA-4 Air Filters are also available separately in convenient 10-packs.

Works very well


It took only about an hour to install and keeps my brain nice and cool during hot days lapping. It is loud however, so expect that car / other racers will be less audable.
