2 min read

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.

Purpose of the ARC CO2 6000L System

The ARC CO2 6000L is a professional carbon dioxide removal system (CO₂ scrubber) developed for:

Civil defence shelters
Protective bunkers
Industrial protected facilities
Enclosed emergency spaces

The system is designed to regenerate indoor air by removing carbon dioxide generated through human respiration. According to the product specification, it also supports the removal of harmful gases such CO₂ (carbon dioxide), extending the period people can safely remain inside isolated shelters without external air supply.

Modular Filtration Design

A key feature of the ARC CO2 6000L is its modular architecture.

The replaceable CO₂ filters may be connected inline in configurations of:

Single filter
Two filters
Three filters

Each individual filter provides an absorption capacity of:

More than 6000 liters of CO₂

This modular approach allows the system configuration to be adapted according to shelter size, occupancy and operational requirements.

Air Regeneration Principle

The ARC CO2 6000L functions as an air regeneration solution rather than a conventional ventilation unit.

Instead of supplying fresh outdoor air, the system continuously treats the internal atmosphere by reducing carbon dioxide concentration generated by occupants. This helps maintain safer breathing conditions during sealed shelter operation when external air intake is unavailable.

According to the manufacturer, these systems are intended for isolated spaces where maintaining controlled concentrations of CO₂ is essential for extending shelter occupancy.

Technical Specifications

Main characteristics published by Shelter-Shop include:

Specification	Value
Airflow	190 / 230 / 250 m³/h
CO₂ Filter Capacity (each)	>6000 L CO₂
Electrical Supply	230V or 115V AC (single-phase)
Manual Backup	Optional

Advantages of the Modular Configuration

The modular concept enables flexible system design depending on shelter requirements.

Potential benefits include:

scalable filtration capacity
replaceable filter modules
adaptable installation layouts
compatibility with different shelter sizes
continuous air regeneration during isolated operation

Because filters can be arranged in multiple inline configurations, the installation may be expanded when additional CO₂ absorption capacity is required.

Applications

The ARC CO2 6000L is intended for use in:

Civil defence shelters
Blast-resistant bunkers
Underground protected facilities
Emergency command centres
Industrial safety shelters
Long-duration protected occupancy areas

These applications require dependable atmospheric control when occupants remain inside enclosed environments for extended periods.

Shelter Integration

Within a complete shelter ventilation system, the ARC CO2 6000L complements protective air filtration equipment by addressing one of the primary challenges of sealed occupancy—the gradual accumulation of carbon dioxide from human respiration.

The modular scrubber is designed to integrate into protected shelter infrastructure while providing configurable filtration capacity through replaceable filter modules.
