Atmas offers a wide selection of CBRN/NBC/TIC air filtration systems and other solutions for for civil defence shelters, bunkers, safe rooms, chambers, and other protective, industrial and commercial applications.

 

We offer a complete selection of solutions for facilities of all sizes, starting from small private safe rooms and up to very large special purpose facilities designed for thousands of occupants. Our advanced, certified and cost-effective solutions are installed in tens of thousands of shelters, government, industrial and private facilities, around the world.

​

NBC (Nuclear, Biological, Chemical) / CBRN (Chemical, Biological, Radiological and Nuclear) / TIC (Toxic Industrial Chemicals) air filtration systems are designed to provide fresh filtered from contaminants and particles air into protected spaces for creating a toxic free area (TFA). Depending on their purpose and integrated filters such systems can filter different war or industrial gases and chemicals, biological particles like viruses and bacteria, radiological and nuclear particles and materials, as well as coarse and fine dust and more.

Integrated into the systems filters define what kind of gases and particles the filter can filter/adsorb. The filters usually have to meet the requirements of different civil defense standards or can be specially designed to meet specific purposes. As an example, in nuclear power plants and nearly located facilities commonly there are requirements for additional Iodine adsorption capabilities of the filters. 

​

NBC filtration systems can be installed together with air handling units (AHU) in large shelters to distribute the air correctly to all parts of the shelters and prevent concentration of carbon dioxide (CO2) and maintain correct levels of oxygen (O2) in all rooms and parts of the shelter. In smaller shelters the air can be distributed by the system itself with support of air duct and placement of overpressure valves.

​

For shelters, bunkers and facilities that can be operated in isolation mode systems air regeneration systems need to be added – carbon dioxide (CO2) removal systems (scrubbers) and compressed air/oxygen (O2) supply systems for maintaining required levels of CO2, O2 and overpressure.

SAFE 360

CBRN Filtration System for Safe Rooms and Small Shelters

Arconik SAFE 360 is a perfect air supply solution for residential shelters, small bunkers, safe rooms, panic rooms, container-based structures and more.
The system is designed to operate both in clean ventilation and CBRN (chemical, biological, radiological, and nuclear) filtration modes. When switched on SAFE 360 designed to provide fresh and filtered air into the shelter as well as to create overpressure (relative positive pressure) in gas tight shelter.

ARC Series

CBRN Filtration Systems for Small, Medium and Large Shelters

Arconik ARC Series is a line of CBRN air filtration systems designed for various sizes of shelters up to 1,800 m3 air volume. The ARC line currently includes ARC 100, ARC 180, ARC 240, ARC 300, ARC 450, ARC 900, ARC 1200 and ARC 1800. The number in the ARC systems states the airflow in CBRN filtration mode (ARC 180 provides 180 m3 of air per hour). 

ARC systems have modular design allowing various installation options (left, right, different height and installation of components on different walls) what is extremely important for limited space in shelters, bunkers, safe rooms, machine rooms, etc. 
ARC systems 100, 180, 240, 300, 450 and 600 includes manual backup and beside the standard floor installation can be installed also on the wall (floor-free) or hidden (covered by design elements) what allows to maximize the shelter space as well as to use the shelter for dual use purposes as a standard room, office, storage space and more.
ARC 900, 1200 and 1800 are designed for larger facilities which are equipped with backup generators and allow only floor installation option.

 

Highlights

  • Professional and rugged systems, design for operation in different conditions (temperature, humidity, shock, etc.) and designed to comply with requirements of modern civil defense standards or can be customized to client’s/local requirements.

  • ARC systems installed in hundreds of shelters located in high secured facilities, schools, kindergartens, hospitals, apartments, office buildings, commercial and industrial buildings and more.

  • Wide range of systems for various shelter sizes. 

  • CBRN Filtration and ventilation modes (bypass mode).

  • Modular design and various installation options space optimization

  • Manual backup option (for ARC 100 – 600) for cases of power outage

  • Typically, ARC type systems include blast valve, prefilter, airflow volume regulator, NBC filter, electrical blower, manual backup for the blower, overpressure valve/s and connecting chemical resistant and clean air duct and hoses.

Filter Banks

Specially Designed CBRN Filtration Systems for Large Shelters & Facilities 

Filter-banks are large CBRN filtration systems designed for project the specific air volume according to the project requirements and can combine number of NBC/CBRN or CO2 filters connected between them into one unit. Various NBC filter options can be used in the design (600, 900, 1,200, 1,800 CMH) creating a unit that can supply very high air volume in both NBC filtration and ventilation modes. Because of the modularity of such units, they can be designed to fit a limited and non-standard available space of the machine room or the toxic free area (TFA) of the shelter itself. 
The filter banks can be designed considering the special requirements of the shelter, its size, the number of people, the allocated space, as well as according to local or international standards, regulation or construction norms, climate zone and environmental conditions, shock resistance and blast protection requirements, and many other factors. A single shelter can have multiple filter-banks to accommodate any size of shelter and any number of people.
The Filter-Banks are based on standard and certified components, ensuring the safe operation of the system and can also be designed as manual, semi or fully automated with connection to an SMS (Shelter Management System) and an off-site remote operator.
Such Filter-Banks are usually installed in Subway Stations, Hospitals, Underground Parking Lots, Tunnels or any other large governmental or civil defense shelters.

​

Highlights
