Brief introduction of gas mask

There are many kinds of gas masks, which are usually divided into two categories according to their structure and working principle: air filter masks and air supply masks. The working principle of air filter mask, referred to as filter mask, is to make the air containing harmful substances filtered by the filter material of the mask and inhaled by people. The structure of the filter mask is divided into two parts, one is the mask body, and the other is the filter material, including dust-proof filter cotton and gas-proof chemical filter box. Blowing mask refers to a clean air source that isolates harmful substances. It is delivered to people's face for breathing through pipelines and masks through power functions such as air compressor and compressed air cylinder device. Electrostatic filtering materials and special-effect activated carbon are used to remove odor layers, and gas masks are used to protect particulate matter and organic odor. They are used in petrochemical, chemical, metal smelting and manufacturing industries, and also in some special forces.

High efficiency electrostatic filter (beyond NIOSH requirements) has low respiratory resistance.

Remove the odor layer and feel the special effect of fresh air.
