Axis Hobby-Aire 1 Full Facemask Breathing System Painting in enclosed areas? Protect your lungs – You only get one set! This Hobbyair system pumps a steady flow of fresh air for maximum protection against isocyanates, vocs, particulates and other toxins. The Hobbyair is designed around a reliable 2-stage turbine. It provides breathing air to a full-face mask through a 40-ft. kink-resistant, FDA-approved breathing hose, lightweight silicone rubber full-face mask. Don’t forget to order lens protectors and a replacement face lens for backup. Once you start using the Hobbyair, you will agree that the benefit of breathing a plentiful flow of fresh air are much more comfortable than a filtered mask. Remember, a filtered/cartridge mask will NOT protect you from all refinishing chemicals!
