CBRN, CO2, CO & Special 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:
Tested and certified filters according to modern civil defence and safety
Various sizes available for different nominal airflows
Multi-layer filtration for maximum efficiency (HEPA, activated carbon, etc.)
Special design of the filters allow long storage time
Standard and customized design to fit different types of air filtration systems
Tested and certified by various international institutes
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 removal of CO2 and CO from air in evacuation chambers and shelters
Scalable solutions for various sizes and types of facilities
Can be equipped with detectors and systems for continuous air quality monitoring and control
Can be combined with oxygen and air supply and control units
Modular design and simple operation
Blast Valves, Overpressure Valves & Gas-tight Valves
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.
Key Features:
Blast valve - normally open valve, protects the inner space from blast wave effects.
Blast dampers - blast protection devise for protection of ventilation systems against blast 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.
O2/Air Supply & Overpressure 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
Ventilation High Pressure 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.
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 (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.
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, 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. Our detectors can monitor gases like CO, H2S, SO2, O2, O3 and other gases
Key Features:
Real-time gas detection with high sensitivity
Visual and audible alarm systems
Network integration for centralized control
Calibration-free sensors
SHELTER AIR MANAGEMENT
Professional Ventilation, Filtration & Air Management Solutions for Shelters
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.
