Product Description
The ARC CO2 1500L is a standalone carbon dioxide removal system designed for confined environments with limited fresh air supply and potential CO2 accumulation. This equipment has been developed for use in civil defence shelters, bunkers, control rooms and isolated spaces, ensuring the maintenance of a breathable and safe environment during extended periods of isolation.
Through a replaceable chemical cartridge system, the unit absorbs CO2 generated by human respiration and other sources, contributing to the regeneration of air within the protected space. Its standalone configuration, combined with multiple power supply options, enables operation in off-grid scenarios or during infrastructure failures, making it a critical solution in emergency and preparedness contexts.
