CBRN filtration banks, by Beth-El Industries, have been developed for over 40 years to protect infrastructure such as hospitals, nursing homes, kindergartens, schools, corporate offices, banks, military installations, and war rooms. The systems provide a central shielding layer for critical infrastructure and essential service providers, including many varying government and civilian entities.
The filtration systems create a profound sense of personal security for hundreds or thousands of shelter occupants, since the possibility exists for them to enter the reinforced room at any given moment and to stay within optimum protection from chemical, biological, radiological, or nuclear attacks for a significant duration of time without having to wear personal protective clothing or even gas masks.
The systems are generally installed inside dedicated machine rooms, the main components of which include the following:
- Blast valves and air inlets
- Batteries of interconnected NBC filters
- Sealed metal piping to convey air
- Suction blowers and cyclone filters
- Release valves that provide pressure control
