Maintaining breathable air quality inside enclosed shelters is one of the most critical aspects of life-support engineering. During prolonged operation in lock-up mode, carbon dioxide (CO₂) generated by human respiration gradually accumulates and must be removed to maintain safe atmospheric conditions. The ARC CO2 4800L is a professional carbon dioxide removal system (scrubber) developed by Atmas Group specifically for civil defence shelters, bunkers and industrial protected

Modern civil defence shelters and protected facilities require reliable air regeneration systems capable of maintaining safe indoor conditions during periods when fresh air cannot be supplied from outside. The ARC CO2 6000L Modular CO₂ Scrubber is designed specifically for this purpose, providing controlled removal of carbon dioxide (CO₂) while supporting safe occupancy in enclosed environments.
