CBRN FILTRATION BATTERIES

mark — Thu, 11 Dec 2025 20:01:52 +0000

Filter-banks are CBRN filtration systems which include several CBRN or CO2 filters connected into one system for providing large volume of filtered air. Such systems typically designed for specific project requirements and can combine up to 10 connected parallel filters in one system. Scalable CBRN Filtration Systems for High-volume Air Filtration in Shelters and Hardened Facilities.

Depending on the required air volume, various filter options can be utilized, including AFU 600, AFU 900, AFU 1200, and AFU 1800. These units are designed to provide exceptionally high air volume in both NBC filtration and ventilation modes. Their modularity allows for flexible integration, even in confined spaces such as machine rooms or toxic-free areas (TFA) within shelters.

The filter banks are customized to meet the specific requirements of the shelter, taking into account factors such as available space, air volume, occupancy levels, compliance with local or international standards, construction norms, climate conditions, shock resistance, and blast protection needs. A single shelter can be equipped with multiple filter banks to accommodate varying capacities and operational demands.

Built using certified components, these filter banks ensure safe operation and can be designed as manual, semi-automatic, or fully automated systems, with integration to Building Management Systems (BMS) and remote operation capabilities.

These systems are commonly deployed in subway stations, hospitals, underground parking facilities, tunnels, and other large-scale governmental or civil defense shelters.

System components are tested and certified for SI 4570 standard or designed to meet technical requirements of various international standards for air filtration systems for shelters.
Systems are approved by civil defense authorities in different countries.
Company systems are installed in tens of thousands of shelters around the world.

Specifications

Custom design for specific airflow (starting from 1,200 to 18,000 m3/h, and even larger), using standard filters and components.
Designed to meet project specifications and various international standards
Multiple systems can be installed in a single shelter to meet any airflow requirements.
Semi-automatic / automatic control options
Can be integrated with various building management software and remote control

Configuration Options

Filtration batteries can be designed for manual or automatic operation from remote control or building management system (BMS)

Filtration batteries can be configurated according to specific customer requirements including airflow, allocated space, filtration standards, automation and more.

Manual operation – CBRN filters are kept hermetically sealed from the factory and connected by operator only in case of emergency. AFU type filters are equipped with quick connectors and can be connected in minutes. The system can be equipped with manually operated gastight valves or motorized gastight valves (GTVs) for air regulation which can be set by the operator in required position manually or from RCU.
Automatic operation – CBRN filters are pre-connected to the system and the system can be configurated to start by press of the button or automatically by signal from RCU, BMS or detectors in case of emergency. The system can be equipped with manually operated with motorized gastight valves (GTVs) for air regulation which can be set by the operator in required position manually or automatically to control the airflow in separate filters or complete system.
Other combinations between manual and automatic operation can be configurated.

Automation and Remote Control Options

Filtration batteries can be designed for automatic operation from remote control or building management system (BMS). Remote control unit for system monitoring and control, can be connected to building management system and detectors.
