Various CBRN/NBC filter options can be used in the design (600, 900, 1,200, 1,800 CMH) creating a unit that can supply very high air volume in both NBC filtration and ventilation modes. Because of the modularity of such units, they can be designed to fit a limited and non-standard available space of the machine room or the toxic free area (TFA) of the shelter itself.
The filter banks can be designed considering the special requirements of the shelter, its size, the number of people, the allocated space, as well as according to local or international standards, regulation or construction norms, climate zone and environmental conditions, shock resistance and blast protection requirements, and many other factors. A single shelter can have multiple filter-banks to accommodate any size of shelter and any number of people.

The Filter-Banks are based on standard and certified components, ensuring the safe operation of the system and can also be designed as manual, semi or fully automated with connection to an SMS (Shelter Management System) and an off-site remote operator.
Such Filter-Banks are usually installed in Subway Stations, Hospitals, Underground Parking Lots, Tunnels or any other large governmental or civil defense shelters.
