NBC / CBRN Filtration Batteries - Multifilter Systems

Scalable multi-filter systems, designed specifically for the project in large scale civil defence shelters, bunkers and protected spaces with air volume from 1800 and up to 18000 m3 air volume (per 1 system).

All parts of the systems are tested and certified for SI 4570 standard by the Standards Institution of Israel and can be certified to other standards.

Overview

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.

Configuration Options

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

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

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.

*Remote control unit for system monitoring and control, can be connected to building management system and detectors.
