2.Product description
This positive pressure air breathing apparatus is composed of the following parts:
1 Full Face Mask 2 Demand Valve 3 Pressure Reducer and Cylinder Valve 4 Pressure Gauge and Warning Device 5Back Plate Assembly with Harness 6 Medium Pressure Hose 7 Compressed Air Cylinder
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 .
Back plate assembly includes back plate ,harness ,waist belt ,buckle,pressure reducer holder and cylinder tightening belt,Injected with flame resistant plastic and carbon fiber material ,the back plate is compact, light,,high mechanical resistant ,and anti-impact.It is designed to fit human body’s back,notably regarding ergonomics and comfort,All the components of the back plate assembly are fire retardant treated.
The cylinder is made from fully wrapped carbon fiber reinforced aluminum lined with 6.8 L capacity,it ensures one hour of moderate activity in real use. 300bar high pressure breathing air stored in carbon fiber cylinder to ensure long time and steady air supply, also meet EN12245 standard .
Black molded ,high-density polyethylene cases are ideal for carrying and storing SCBA .cases have a two piece hinge and replaceable latches.it provides excellent
storage for SCBA 30min,45min,60min,90min units. Orange case for your option .
