The self-rescuer is an isolated and regenerative self-rescuer with compressed oxygen as the gas source. The human respiratory system is isolated from the outside world, which can prevent various toxic and harmful gases from entering, and can be used when people in distress escape. The self-rescuer has three oxygen supply modes, quantitative oxygen supply, automatic oxygen supplement and manual oxygen supplement. Make performance more reliable and stable. It has the characteristics of small size, light weight, and convenient carrying (the non-metallic material of the shell meets the requirements of the GB3836.1-2000 standard).
