Air Breathing apparatus can be widely used in fire fighting, petroleum, chemical, metallurgy, electric power, shipbuilding, military, police and other industries, ,it's an breathing apparatus for people who works in the environments with oxygen deficiency, toxic gas, thick smokes, etc. Set approved by CE EN 137 standard , to ensure you an assured using experience . Positive pressure air breathing apparatus is designed for the use in fire fight application, chemical industry , metallurgy, mines, petrol industry , rescue operation, maintenance works and polluted area wherever there is or may be oxygen content than 17% , or fog caused by fire accident. Air is compressed in the cylinder (pressure of 30 Mpa) .
Compressed air is reduced to (0.75±0.15) Mpa through the pressure reducer, and led to medium pressure hose .Then it is reduced n pressure again through the demand valve and provided to user through full face mask . The outside toxic gas or particles can not get inside because the pressure inside the mask is always higher than the atmospheric pressure .Thus the tightness of the face mask is guaranteed .all shapes.
