Widely applied in the place of oxygen deficit/hypoxia, high or unknown concentrations of toxic gases, endangering human health. Such as fire-fighting, petroleum and petrochemical, ship, mining, metallurgy and chemical industry, the public emergency.

Main Components
1. Silicone Full Face Mask
The silicone mask body is particularly soft on the skin and remains extremely flexible at high and low temperatures.The mask is equipped with a PC anti-fogging visor with 180 wide angle, which guarantees a large field of vision with panoramic view.
 
2. Demand Valve
Incorporated into the face mas is demand valve. It provides a safe positive connection between the face mask and the regulator and prevents accidental disconnection. 
 
3. Carbon Fiber Cylinder & Cylinder Valve
Lightweight yet robust, this breathing apparatus features outstanding thermal, impact and chemical resistance properties. The valve is anti-error hand wheel meets European standard.  Cylinder valve with no indicator, one indicator and two indicators are optional. 
 
4. FC Cotton Back Plate & Harness
This carrying system has been developed to provide improved stability and reduce back strain, stress and fatigue by following the natural contours of the body. Robust ergonomic design maximising comfort, mobility and strength.
