NBC / CBRN Filtration Systems 

The CBRN filtration and ventilation systems for civil defense shelters, bunkers and protected environments, offering maximum protection against chemical, biological, radiological, and nuclear (CBRN) threats. The systems ensure supply of filtered, breathable air even in the most hazardous conditions.

CO2 / CO Removal Systems - Scrubbers

Atmas CO2/CO removal systems (scrubbers) are designed to maintain safe levels of carbon dioxide and carbon monoxide in the air inside isolated shelters or rescue chambers. Such systems are critical for long-term occupancy in sealed environments to support continues operations in high-risk areas.

Blast Valves & Airflow Control Devices

Blast valves and dampers, overpressure valves, gas-tight valves and other ventilation protection valves designed for controlled air regulation and blast protection in gastight shelters and protected spaces. Our valves are certified and approved for installation as part of CBRN filtration systems.

Oxygen & Air Supply Systems

Oxygen supply systems ensure adequate O2 levels in enclosed environments, while overpressure systems maintain a controlled internal atmosphere, preventing the infiltration of contaminants.

NBC / CBRN & Combined Carbon Filters

These specialized filters provide comprehensive air purification, targeting harmful gases, toxins, and particulates. Designed for integration into ventilation systems, they ensure safe air in contaminated environments.

CO2 / CO Filters

​CO2 / CO filters are part of carbon monoxide and carbon dioxide removal systems (scrubbers) or ventilation and air handling units which design to recirculate the air. Such filters are used for "scrubbing" the air removing the CO2 or converting the CO.

Ventilation Blowers for Shelters

Our blowers has unique features and designed for integration in ventilation systems of civil defence shelters and industrial facilities to ensure efficient air supply and continuous operation even in challenging conditions and loads.

Blast / Gastight Piping

Blast protected wall entrances and gastight air duct are part of CBRN filtration and ventilation systems in shelters. They are designed to protect the internal space from explosions and penetration of contamination into the shelter.

Overpressure (Differential Pressure) Gauges

Overpressure gauge / meter is a devise used to measure and monitor the differential pressure between shelter compartments (shelter main chamber, airlock, etc.) or between the protected area and outside. Overpressure is a critical part of the protection layers in the shelter and it is vital to constantly monitoring its values.

Gas Detection Solutions for Shelters

Our gas detection systems continuously monitor air quality, providing real-time alerts for the presence of toxic gases, smoke, or chemical agents. They are essential for early detection in hazardous environments. Our detectors can monitor gases like CO, H2S, SO2, O2, O3 and other gases

Life-support systems

NBC / CBRN / CO2 / CO filtration systems are part of the life-support and collective protection systems required for protection and creating conditions for normal operations and stay in shelters, bunkers and various types of special purpose military, government, municipal, industrial or private facilities. Such shelters are commonly used in civil defense shelters, command and control centers, data centers, hazardous industries, nuclear power plants, schools, hospitals and common areas equipped with protective space.

The air supply systems are complex systems which include large number of components and systems designed for the specific purpose.
