Positive pressure fire-fighting air respirator consists of 12 components. The characteristics of each component are introduced as follows:
1. Mask: It is a large viewing window, suitable for Asians Face shape, the face window lens is made of polycarbonate material, which has high transparency, strong wear resistance, and anti-fog function.

2. Gas cylinder: It is an aluminum-lined carbon fiber fully wound composite gas cylinder with a pressure of 30MPa. It has light weight, high strength, good safety performance, large gas storage capacity, long use time, and the bottle valve has high-pressure protection. device.
3. Bottle belt group: The bottle belt card is a quick cam locking mechanism and ensures that the bottle belt is always in a closed loop state. The cylinder will not flip over.
4. Shoulder straps: Made of flame-retardant polyester fabric, the straps adopt a bilaterally adjustable structure so that the weight falls on the waist and hips, reducing the pressure of the shoulder straps on the chest and making breathing smoother. And there are large elastic pads on the shoulder straps to reduce pressure on the shoulders.
5. Alarm whistle: placed on the chest, the alarm sound is easy to distinguish, small in size and light in weight.
