RHZYC240 positive pressure type fire oxygen respirator (hereinafter referred to as the respirator) is based on carbon fiber cylinder bearing compressed oxygen gas source of the closed loop breathing and protection device for the human body, can give the staff in the wear the inner loop of oxygen supply, at least 4 hours to complete isolation outside ambient air, absolute respiratory protection effect. This product fully absorbs the domestic and foreign similar products of advanced characteristics, on the design of major outstanding features: compact structure, wearing comfortable, small size, large gas storehouse, light weight, easy tear open outfit, easy to use, impact resistance and other advantages.
This product is suitable for firefighters and rescue and ambulance crews in toxic, hypoxia, smoke, harmful pollutants suspending in the air medium environment work in the disaster relief or disaster. It is mainly used for disaster relief, disaster treatment, mines, tunnels, sanitation, chemical plants, and wear use in survey work.
