The truth about CFM

•

Fresh Air systems in the racing industry are measured in CFM because that's the number printed on the fan. That number may be accurate at the business end of the fan out of the box, but a lot more comes into play when you add a housing, ports, hoses, how it's mounted and how the hoses are run.

Different motors and housings create different torque and will more effectively push air through a hose and into your helmet.

Part Velocity (ft/min)
RaceAir Boost 3200-3600
RaceAir Max Single, Dual and Quad 2700-3200
RaceAir Flow Single 2400-2800
RaceAir Lite 1600-1800
RaceAir Mini 1200

All numbers above are measured using a digital anemometer at the end of a 6' RaceAir hose. The range is due to different angles/bends of the hose we tested during the study. Keep in mind when mounting your RaceAir hoses, several bends will decrease airflow. RaceAir Mini number is measured at the output as it is mounted directly on the helmet without a hose.
