Civil Defense Filtration Absorber (hereinafter referred to as the Filtration 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, fog, biological aerosols, radioactive dust, and persistent contaminants from the air, making it clean. Primarily installed in chemical defense level B and C civil defense facilities.

Process air by removing chemical agents, biological agents, and radioactive dust using a free radical activator, fine filter, and filter decontaminator, while destroying microorganisms retained in the fine filter unit.

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