CBRN filtration system
A rugged and crank system to filter CBRN agents
A CBRN fallout shelter requires special closing devices* for all openings in the shelter envelope as well as a ventilation/filtration system for NRBC contaminants (chemical, biological, nuclear, radioactive and nuclear).
* Gastight blast doors, blast valves, overpressure valves…
The ventilation systems that equip our anti-atomic shelters offer protection against a very wide spectrum of nuclear, biological and chemical pollutants. They have been tested and certified by independant laboratoires and approved by many civil defense offices all around the world.
How does ventilation work inside fallout shelters?
The CBRN ventilation/filtration system provides breathable and clean air to the occupants and ensures an overpressure of 50-250Pa in the same time. It consists of a fan (VA) that draws outside air towards pre-filter and a blast valve (ESV-VF). If air contamination occurs in case of major disaster, the filter will remove all toxical agents before pulsing it in the safe area. The amount of air required is regulated by the integrated air flow meter. Finally, even in case of electrical blackout, the device can be rescued manually using a crank.
Technical specifications:
- Integrated air flow meter
- Integrated adjustment throttle
- Quick connectors
- Integrated pre-filter
- Integrated anti-explosion valve
- Emergency crank

A full range of CBRN and blast protection components
Bünkl is the only French company providing CBRN filtration system as well as the ecosystem of components that ensures air filtration and blast protection for fallout shelter.
BVNO – Blast valves & dampers
BVNO Automatic action, normally open valves for installation on ventilation openings for protection of internal spaces against destructive blast wave effects.
BVNC – Overpressure blast valve
BVNC overpressure blast valves are normally closed valves, designed to control the overpressure level in the gastight shelter and between compartments like airlocks and more.
Gastight/shut-off valves
Gastight valves are designed for installation on entrance or as part of the ventilation ducts to isolate areas from hazardous gases during emergencies.
