Component description:
1. Air respirator mask: it is a large field window, and the lens of the window is made of polycarbonate, which has high transparency, strong wear resistance, and anti fog function. The mesh headwear style is comfortable and convenient to wear. The gel is made of silica gel, which is non-toxic, tasteless, and non irritating, and has good air tightness.
2. Air supply valve of air respirator: simple structure, strong function, large output flow, bypass output, small size.
3. Belt set of air respirator: buckle is locked and easy to adjust.
4. Quick connector of air respirator: small, can be operated by one hand, and has locking and anti falling function.
5. Pressure reducer of air respirator: small size, large flow, stable output pressure.
6. Bottle head valve of air respirator: It is equipped with high-pressure safety device and has small opening torque.
7. Backrest of air respirator: the design of the backrest conforms to the ergonomic principle. It is injection molded from carbon fiber composite materials. It has flame retardant and anti-static functions, and is light and strong. The inside of the backrest is lined with elastic pads, which can make the wearer comfortable.
8. Shoulder belt of air respirator: made of flame retardant polyester fabric, with adjustable structure on both sides, so that the weight falls on the waist and crotch, reducing the compression of shoulder belt on the chest, and making breathing smooth. And there is a wide elastic pad on the shoulder belt to reduce the compression on the shoulder.
9. Pressure gauge of air respirator: large dial, night vision function, rubber protective cover.
10. Air respirator alarm whistle: placed in front of the chest, the alarm sound is easy to distinguish, small in size and light in weight.
11. Air respirator bottle belt group: the bottle belt clamp is a quick cam locking mechanism, and the bottle belt is always in a closed loop state. The cylinder will not turn over.
12. Air respirator cylinder: aluminum liner carbon fiber fully wound composite cylinder with working pressure of 30MPa, light weight, high strength and good safety performance, and the cylinder valve is equipped with high-pressure safety protection device.
