The CBRN Air Filtration Station CBRNX3 is widely used for NBC protection in Civil Defence and military shelters for filtration of Nuclear Fallout and Biological and Chemical Warfare agents. The CBRN Air Filtration Station CBRNX3 is designed to optimize efficiency/ floor space ratio in the HVAC and Air Handling plant rooms by providing maximum filtering efficiency.


The Castellex CBRNX3 Air Filtration Station is a high-efficiency particulate aerosol (HEPA H14) filter and an Activated and Impregnated Carbon gas adsorption filter enclosed in steel containers (NBC cells) and providing a three-stage filtration of the air intake. Aerosol and particle filtration followed by gas adsorption. The filter is enclosed in a rigid gastight container made of steel. Container design ensures shock and blast resistance of the NBC cell. An advanced carbon packing and compression system are applied to guarantee that the carbon beds retain their integrity and tightness. NBC cells composed of layers of prefilters, HEPA element and activated carbon compressed in the way to guarantee that beds retain their integrity. Whole NBC system designed to retain integrity and tightness even in extreme usage/ conditions.
