Painting in enclosed areas? Don't take chances with your lungs. Hobbyair and Citation Systems pump a steady flow of fresh, outside air into paint booths and other confined work areas for maximum protection against isocyanates,vocs, par- ticulates and other toxins. The Hobbyair is designed around a reliable 2-stage turbine. It provides breathing air to a full or half face mask through a 40ft kink-resistant FDA approved hose. It's lightweight, silicone rubber face masks are FDA approved as well. Has beltline hookup and snap-tight fittings.
