Shelter Units
A shelter ventilation unit is a mandatory ventilation device, compliant with regulations, that passes outdoor air through filter stages during war, nuclear, biological or chemical (NBC) threats to supply clean air into the shelter. In normal times it delivers fresh air with a G4 coarse filter; in danger it engages activated carbon, radioactive HEPA and lead separator stages.

Frequently Asked Questions
Is a shelter ventilation unit mandatory?
Yes. It is mandatory in buildings above a certain size under the zoning law and related regulation.
Which capacity should I choose?
It is determined by shelter volume and occupancy. Use the table above to find the capacity (m³/h) you need, and contact us for requirements outside the table.
What do the filter stages do?
The G4 coarse filter captures dust, the AC100 activated carbon filter removes chemical gases and odour, and the NBC filter screens nuclear, biological and chemical threats.
Does it work in normal times?
Yes; in normal times it supplies fresh air with a G4 filter, and NBC filter stages engage during danger.
