Other technical parameters of the product:

Mask: large field of vision spherical mask, small nose mask, suitable for Asian nose and mouth features, good fit, head net made of mesh material. There is no visual deformation, with anti fog function, long-term anti scratch, equipped with pressure head up display function, which can display the residual gas state through red, yellow and green colors according to the pressure of the empty exhalation bottle. The pressure head up display device is easy to disassemble and not easy to damage, and equipped with a constant current mask and a mask protection bag.

Air supply valve assembly: small size, does not affect the lower vision, does not need to locate and quickly connect the mask, can rotate 360 degrees, the air supply is not less than 500L / min, the air supply valve is located directly below the mask. The output pressure adjustment part of the pressure reducer is provided with a locking device, and the output end of the pressure reducer is provided with a safety valve. Equipped with double display mode intelligent electronic pressure gauge, which can display both digital pressure and mechanical pointer pressure. The continuous working time of the digital display pressure gauge is ≥ 30h, when the battery power is only 20% of the total power, there is an under voltage warning light; the explosion-proof grade of the pressure gauge is ≥ IP67. After opening the cylinder valve, the digital display screen can display the pressure value, remaining gas volume, available time and working environment temperature in the cylinder. When the cylinder pressure is less than 6Mpa, it can give an alarm with the sound intensity > 90dB (a).

Back with components: made of high-strength non-metallic flame-retardant materials, designed according to the body shape of Chinese people, the weight is distributed in the waist, reducing the stress on the shoulder, with good fit and flexibility, bending with the movement and deformation of the human body, the outer textile materials of the back frame are flame-retardant materials, anti-static and corrosion-resistant, and the shoulder belt is equipped with reflective tape.

Wear mass: 10.8kg, high temperature resistance: 769pa, low temperature resistance: 645pa, air tightness of the whole machine: 1.6Mpa, static pressure: 333pa.

Equipped with: O-ring and other spare parts, vulnerable parts, solid wrench and other special tools.
