CO2 Removal Systems — Scrubbers
Professional carbon dioxide removal systems for civil defence shelters, bunkers, safe rooms and industrial applications. Keep your shelter air safe and breathable in close-up mode.
ARC CO2 Professional Series
The ARC CO₂ Professional Series includes a range of advanced carbon dioxide removal systems (scrubbers) designed for integration into air filtration units, air regeneration systems, shelters, protected areas, and various industrial applications. These air regeneration solutions are engineered to remove harmful gases, including carbon monoxide (CO) and carbon dioxide (CO₂), helping maintain safe air quality and extending occupancy time in shelters and other enclosed environments. The systems can operate in isolated spaces without an external air supply, allowing for extended protection by continuously managing CO₂ and CO levels to maintain a safe and breathable atmosphere.
Key Features
Air Regeneration
Engineered to continuously "scrub" the air by removing harmful gases, including carbon monoxide (CO) and carbon dioxide (CO₂), allowing for extended occupancy in sealed or enclosed environments.
Extended Stay Time
Allows operation in isolated spaces without an external air supply by maintaining safe levels of CO₂ and CO within the environment.
Quick Filter Swap
Replacement filters should be kept sealed until required. When replacement is needed, the used filter can be removed and a new one installed quickly and easily within seconds.
Capacity Planning
An average resting person produces approximately 20–30 litres of CO₂ per hour, allowing you to easily calculate the required filter capacity for your application.
CO2 Scrubber Models

Compact CO2 Scrubber
ARC CO2 1500L
Capacity: 1,500 litres CO2
A compact carbon dioxide removal system (scrubber) specifically designed for civil defence shelters, bunkers, safe rooms, and industrial applications. The replaceable filter is capable of absorbing no less than 1,500 litres of CO₂, helping maintain a safe and breathable environment during extended periods of occupancy.

Professional CO2 Scrubber
ARC CO2 4800L
Capacity: 4,800 litres CO2
A professional carbon dioxide removal system (scrubber) specifically designed for civil defence shelters, bunkers, and industrial applications. The replaceable filter is capable of absorbing no less than 4,800 litres of CO₂, helping maintain safe and breathable air quality during extended periods of occupancy.

Modular CO2 Scrubber
ARC CO2 6000L
Capacity: 6,000 litres CO2 per filter
A professional carbon dioxide removal system (scrubber) specifically designed for civil defence shelters, bunkers, and industrial applications. The replaceable filters can be connected inline in configurations of 1, 2, or 3 filters, with each filter capable of absorbing no less than 6,000 litres of CO₂. This modular design allows for scalable carbon dioxide removal capacity based on the size and requirements of the protected space.

High-Capacity CO2 Scrubber
ARC CO2 18000L
Capacity: 18,000 litres CO2
A professional carbon dioxide removal system (scrubber) specifically designed for civil defence shelters, bunkers, and industrial applications. The replaceable filter is capable of absorbing no less than 18,000 litres of CO₂, helping maintain safe and breathable air quality during extended periods of occupancy.

Scalable CO2 Scrubbing System
CO2 Filtration Batteries
Capacity: Project-specific
Scalable professional carbon dioxide removal systems (scrubbers) designed to meet specific project requirements, including shelter size, airflow capacity, carbon dioxide levels, and occupant load. These systems are engineered for civil defence shelters, bunkers, and industrial applications. Multiple replaceable filters can be connected in parallel configurations, with each filter capable of absorbing no less than 18,000 litres of CO₂, providing a flexible and expandable solution for long-duration air quality management.
How to Calculate Your Filter Needs
An average resting person produces 20-30 litres of CO2 per hour. To calculate how many filters you will need:
(Number of Persons) × (20+ Litres) × (Number of Hours)
The volume of the closed space should also be considered to ensure sufficient recirculation of the air and prevent "CO2 pockets" in the room. Spare filters should be kept sealed, and the used filter can be easily replaced in seconds.
