Versatile, customizable ventilation and NBC filtration systems can be accommodated into any armored vehicle chassis, container or mobile shelter. Our NBC units incorporate highly efficient cyclone filters for heavy duty sand, dust and fine dust extraction, as well as pre-filters that catch any remaining fine dust. Dust- and dirt-free air is then pulled through the NBC filter cartridges to remove nuclear, biological and chemical particles. This cleaned air is then vented into the vehicle, shelter or container’s sealed compartments, providing a continuous cycle of safe air for personnel and equipment.
