Collective NBC filter units are designed to filter chemical, biological, and nuclear contaminants. The filters conform to the Israeli Standard 4570 and each filter is thoroughly tested during production and assembly to provide complete filtration. They are delivered hermetically with a tamper-proof seal to ensure longevity and security control.
In an emergency, the NBC filter unit is attached to the filtration system. When not in use, the lids are refastened to retain maximum efficiency by avoiding the penetration of humidity. The filter units can also be connected in parallel to form large filter banks.
