Civil Defense Filtration Absorbers (hereinafter referred to as Filtration Absorbers) are a type of civil defense filtration absorber, which is a core product in wartime ventilation systems. They are 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 the air clean. Mainly installed in level B and C chemical defense and civil defense projects.

Process air to remove chemical agents, biological agents, and radioactive dust using a free radical generator, fine filter, and decontamination filter, while destroying microorganisms retained in the fine filter unit.

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