Air Filtration & Management Systems and Components for Shelters & Protected Spaces

CBRN (NBC) Filtration Systems for Shelters, Bunkers & Protected Spaces

The CBRN filtration and ventilation systems offered by Atmas are especially designed for installation in 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.

Key Features:

• Various standard systems from 36 m3/h and up to 1800 m3/h airflow

• Specially designed filtration batteries that can supply up to 2400-18,000 m3/h of air per unit

• High-efficiency particulate and gas filtration

• Automated and manual operation modes

• Compact and smart design for simple integration in limited space

• Tested and certified for compliance with international safety standards

CO2/CO Removal & Air Regeneration Systems

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.

Key Features:

• Professional scrubbers for CO2 and CO removal

• Continuous air quality monitoring and control

• Modular design and simple operation

• Customizable for various shelter sizes

CBRN, CO2, CO & Other Absorber Based 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.

Key Features:

• Multi-layer filtration for maximum efficiency (HEPA, activated carbon, etc.)

• Long storage time

• Standard and customized design to fit different types of air filtration systems

• Tested and certified by various international institutes

Blast Valves, Blast Dampers, Overpressure Valves & Gas-tight Valves

Blast valves, 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.

Key Features:

• Blast valve - normally open valve, protects the inner space from blast wave effects.

• Overpressure valves - normally closed valve, designed for controlled release of air from the shelter and overpressure maintenance. 

• Gas-tight shut-off valves designed for isolation and airflow control.

Oxygen / Air Supply & Overpressure Maintenance Systems

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

Key Features:

• Stable oxygen delivery for life-support

• Automatic pressure regulation

• Backup systems for emergency scenarios

• Compact and modular design

High & Low Pressure Blowers for Shelters and Industrial Ventilation

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.

Key Features:

• High airflow capacity with high pressure and low noise levels

• Energy-efficient motors

• Certified and tested solutions

• Suitable for harsh environments

HEPA, ULPA & Special Industrial Filters

These filters offer superior particulate filtration, capturing ultra-fine contaminants to maintain sterile conditions in sensitive environments such as cleanrooms and medical facilities.

Key Features:

• High-efficiency particulate filtration (99.99%+)

• Custom sizes and configurations

• Low-pressure drop design

• Resistant to chemical and biological agents

Overpressure Gauges - Differential Pressure Measurements 

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. 

Key Features:

• Extremely accurate and reliable gauges

• Analog or digital interface 

• Option to connect the units to RCU or building management systems for remote monitoring

Wall Sleeves, Retrofit Flanges & Cable Transmitters

To keep the shelter blast and gastight perimeter protected, different devices like wall sleeves and multiple cable transmitters (MCT) must be used. Such solutions are integrated into concrete shelter perimeter to allow penetration of duct, electricity and communication cables, water lines and other while keeping blast protection and gas tightness.  

Key Features:

• High quality professional solutions

• Various sizes and options available

• High blast rating and gas tightness 

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.

Key Features:

• Real-time gas detection with high sensitivity

• Visual and audible alarm systems

• Network integration for centralized control

• Calibration-free sensors
