Civilian Defense Filtration Absorber (hereinafter referred to as the Filter Absorber) is a type of civil defense filtration absorber, which is a core product in wartime ventilation systems. It is mainly used in ventilation systems for contaminated air in civil defense projects.

Effectively filters toxic smoke, mist, bioaerosols, radioactive dust, and persistent contaminants from the air, making the filtered air clean. Primarily installed in level II and III anti-chemical, civil defense facilities.

Process air to remove chemical agents, biological agents, and radioactive dust through a free radical activator, fine filter, and decontamination filter, and kill microorganisms retained in the fine filter unit.

Prevent the large-scale proliferation or migration of biological agents by providing clean air to the fortification.
