Beth-El’s ventilation and NBC filtration systems for air filtration in bomb shelters are collective NBC / CBRN filtration systems intended for protection from conventional warfare or conflicts involving NBC (Nuclear, Biological, Chemical) warfare.
The NBC filtration system creates an overpressure inside the protected area by drawing in outside air and filtering it from harmful particles to provide a safe and comfortable environment. Having a protected area enables freedom of movement without the need for gas masks or protective clothing. All of Beth-El’s wide variety of NBC / CBRN filtration systems operate with normal electric power (three-phase or single-phase) and the FAH systems can be operated by hand with a hand crank in the event of a power outage.
Each system is comprised of an NBC filter unit, a blower unit, and a blast valve or valves to maintain the overpressure in the protected area. All Beth-El filtration systems are custom designed to accommodate specific customer requirements and can protect a space for a single family with the extremely popular ‘Rainbow’ NBC filtration system and anywhere up to 150 people, depending on the individual model of NBC filtration system that is applied. For larger systems to accommodate hundreds or thousands of people, Beth-El also provides NBC filter banks.
