AFU CO2 18000L Carbon Dioxide Filter: Engineered for Large-Scale Shelter Air Management

Maintaining breathable air inside sealed shelters requires efficient removal of carbon dioxide (CO₂). During long-term occupancy, CO₂ generated by occupants continuously accumulates within enclosed environments, making dedicated carbon dioxide filtration an essential part of every shelter ventilation system.

The AFU CO2 18000L Carbon Dioxide Filter is engineered for high-capacity CO₂ removal in civil defence shelters, bunkers, protected facilities, and other enclosed environments where reliable air recirculation is required.

High-Capacity CO₂ Filtration

The AFU CO2 18000L filter is designed to remove large volumes of carbon dioxide from recirculated air.

Its high absorption capacity makes it suitable for installations serving larger protected spaces or systems requiring extended operational capability.

The filter is intended for integration into compatible shelter air management and CO₂ scrubber systems.

Main Technical Specifications

According to the official product page, the AFU CO2 18000L filter has the following specifications:
