ARC 600 NBC / CBRN Filtration System: Professional Air Protection for Large Shelters and Critical Infrastructure

Modern civil defence shelters, bunkers and protected facilities must provide far more than physical protection. During chemical accidents, biological threats, radiological contamination or nuclear emergencies, the quality of the air inside the shelter becomes the most critical factor for occupant safety. The ARC 600 NBC / CBRN Filtration System is a professional air filtration and emergency ventilation solution engineered to create a protected breathing environment while maintaining positive overpressure inside gas-tight shelters.

Designed for medium and large protected facilities, the ARC 600 combines advanced CBRN filtration technology, emergency ventilation and reliable airflow management into one integrated system. It is suitable for government shelters, military installations, industrial facilities, critical infrastructure and high-end residential bunkers requiring dependable long-term protection.

Professional CBRN Air Filtration

The ARC 600 is specifically engineered to protect occupants from Chemical, Biological, Radiological and Nuclear (CBRN) hazards.

During filtration mode, outside air passes through multiple protection stages before entering the shelter, removing hazardous particles and toxic contaminants while delivering clean breathable air.

The system supports the creation of a Toxic Free Area (TFA) by combining filtration with controlled overpressure that prevents contaminated outside air from entering the protected space.

High Airflow Capacity for Large Shelters

One of the key advantages of the ARC 600 is its high airflow capacity.

Filtration Mode

• 600 m³/h filtered airflow

Ventilation Mode

• 1200 m³/h fresh air ventilation

This airflow capacity makes the ARC 600 suitable for shelters with an air volume of approximately 300 m³ per system, while multiple units can be installed for larger facilities.

Maintaining Positive Overpressure

Modern CBRN shelters rely on positive internal air pressure.

The ARC 600 continuously supplies filtered air while maintaining overpressure that forces air outward through specially designed overpressure valves.

This prevents contaminated external air from entering through:

• Door seals

• Cable penetrations

• Small structural leaks

• Utility openings

Maintaining positive pressure is one of the most effective methods of protecting shelter occupants from airborne contamination.

Reliable Operation During Power Failures

Emergency situations frequently involve electrical outages.

For this reason, the ARC 600 includes a manual backup operating system, allowing ventilation and filtration to continue even when electrical power is unavailable.

This redundancy significantly improves operational reliability during prolonged emergencies and disaster scenarios.

Flexible Installation Options

The ARC 600 is available in multiple installation configurations.

Depending on project requirements, the system may be installed as:

• Floor-mounted installation

• Wall-mounted (floor-free) installation

The wall-mounted version helps maximize usable shelter space while maintaining the same filtration performance.

This flexibility allows engineers to optimize equipment layouts for both new shelters and modernization projects.

Complete System Components

The ARC 600 is supplied as a comprehensive shelter air management solution rather than a standalone fan.

A typical system includes:

• CBRN combined filter

• Electric blower

• Manual backup drive

• Blast valve

• Air prefilter

• Airflow indicator

• Silencer

• Airflow control damper

• Overpressure valve

• Air hoses and connection accessories

These components work together to provide reliable filtration, ventilation and pressure management throughout the shelter.

Typical Applications

The ARC 600 is suitable for numerous protected environments, including:

• Civil defence shelters

• Military bunkers

• Government facilities

• Safe rooms

• Industrial protection shelters

• Emergency operations centers

• Data centers

• Critical infrastructure

• Energy facilities

• Border security installations

• Underground command centers

Its combination of high airflow and reliable CBRN protection makes it an excellent choice for projects requiring long-term emergency preparedness.
