CBRN Filtration and Protective Shelter Technologies: Engineering, Equipment and Practical Demonstration
Modern civil defence shelters require an integrated approach to protection. In addition to the physical structure, protected facilities may incorporate CBRN air filtration, emergency ventilation, blast and overpressure valves, gas-tight components and other air-management systems.
Atmas Group provides technologies and solutions for civil defence shelters, bunkers, safe rooms and other protected facilities, including CBRN filtration and ventilation systems, blast valves, overpressure valves, gas-tight ductwork and related shelter equipment. Atmas Group
CBRN filtration and ventilation
CBRN filtration systems are designed for protected spaces such as civil defence shelters, bunkers, safe rooms and other facilities. Atmas Group's product range includes standard and customizable systems for supplying filtered air and creating positive pressure within the protected area. Atmas Group
The Atmas Group range includes systems such as SAFE 360 and the ARC series, with different configurations and capacities for different shelter requirements.
For example, the ARC range includes systems from ARC 50 and ARC 180 through higher-capacity configurations such as ARC 450, ARC 600, ARC 900, ARC 1200 and ARC 1800. The appropriate system is selected according to the characteristics and requirements of the protected space. Atmas Group
CBRN filters
Atmas Group also provides individual CBRN/NBC filters designed for use within shelter ventilation and air-filtration systems.
The company's technical description identifies two important filtration layers: HEPA/ULPA mechanical filtration for airborne biological particles and an activated-carbon layer for adsorption of war gases and toxic industrial chemicals. Some configurations may also include a coarse dust pre-filter. Atmas Group
Blast and overpressure protection
Air-management equipment in a protected facility also includes blast and overpressure control.
Atmas Group offers blast valves, blast dampers, overpressure valves, gas-tight valves, wall sleeves, flanges and gas-tight/blast-rated ductwork. These components are designed for integration into ventilation systems and protected structures. Atmas Group
The company's BVNO blast valves are described as normally open valves that allow airflow during normal operation and automatically close in response to an incoming blast wave. Atmas Group
Integrated shelter solutions
CBRN filtration is only one part of a complete protected-facility system.
Atmas Group's shelter solutions include:
CBRN air filtration and ventilation;
blast and overpressure protection;
gas-tight valves and ductwork;
protective doors and hatches;
shelter equipment;
air-management and monitoring solutions;
project support and system integration.
The company states that it supports projects from design and specification through product selection, supply, integration, installation support, testing, commissioning and modernization. Atmas Group
See the equipment in operation
Technical specifications are important, but practical demonstrations can provide a clearer understanding of how shelter equipment looks and operates.
The Atmas Group YouTube channel contains videos demonstrating different products and technologies. Among the available videos are demonstrations of:
ARCONIK blast valve testing;
SAFE 360 filtration mode operation;
SAFE 360 ventilation mode operation;
the KIBO stand-alone shelter;
other shelter and protective technologies.
For example, the KIBO Stand Alone Shelter video provides a 360° presentation of the prefabricated shelter. YouTube
The SAFE 360 documentation also specifically refers to YouTube demonstrations of both Filtration Mode Operation and Ventilation Mode Operation, allowing viewers to see the system rather than relying only on technical descriptions. Atmas Group
