MSRG Helmet & In-Line Carbon Filter Blower

The MSRG Helmet blower with its unique designed 3D printed case uses a 12V-5W IP68 rated dust and water resistance blower fan which provides a sealed enclosure when using TrackFresh Carbon Monoxide Filters. The blower unit utilises a 3" inlet and should be provided with a 3" NACA duct connection, and on the outlet a Left Hand course thread allowing the helmet hose to be securely fastened directly into the unit and not work it way loose.

Most installations use a rear window to mount the NACA duct, while mounting the blower unit on a cross member of the roll cage so that the unit is surrounded by ambient air and not in direct contact with a heat source. The closer that you can mount the unit to the driver the better it is to reduce air flow loss of long lengths of hose.
