Positive pressure air breathing apparatus
Description
It is mainly used for firefighters or rescuers to safely and effectively carry out fire fighting, rescue work under various environments such as dense smoke, poisonous gas, steam and hypoxia. It is an ideal personal respiratory protection for firefighters and rescuers device. It has the properties of high temperature resistance, flame retardant, insulation, corrosion resistance, waterproof, light weight and good air tightness.
Components: gas cylinder, air supply valve, mask, back frame, pressure reducing valve, safety valve, pressure head-up display device, pneumatic alarm and pointer pressure gauge.
