>Type mine pressure air self-rescue device (Coal Safety Certificate No.:) is mainly used for disaster relief and protection in coal mines. When an accident occurs underground in a coal mine or harmful gases appear and the workers cannot breathe normally, the workers can enter the nearest self-rescue device to avoid disasters. The fresh air transported by the self-rescue device will make the escape Disaster personnel can breathe easily for a long time, achieving the purpose of safely avoiding disasters and stabilizing their working mood. Under normal circumstances, the number of self-rescue devices installed underground shall not be less than one-third of all underground personnel.

The >type mine pressure air self-rescue device is a new type of isolated gas respiratory protection device. This device has six groups in a box (groups can be designed according to requirements), and can provide six groups at the same time. People use it to achieve the effect of taking care of each other.

>The mine pressure air self-rescue device consists of a box, a mounting plate, an air inlet pipe, a door lock, and a respirator (multiple groups) etc. composition. The box body, mounting plate and air inlet pipe are made of stainless steel. The respirator is installed in the box and consists of a regulating valve, a pressure reducing filter valve, a spring hose, a self-priming filter mask, etc. The pressure reducing filter valve filters impurities, water and oil in the air, reduces pressure air noise, and can accurately adjust and control the air supply pressure so that workers can breathe unimpeded, smooth and comfortable.

The > type mine pressure air self-rescue device uses a self-priming filter mask to be worn directly on the mouth for breathing, and breathes through the spring hose The connection does not affect the user's sight. The spring hose can be freely expanded and contracted, and the user can move freely within the expandable range of the spring hose.
