CBRN Vehicle Filters

EMCEL manufacture the CBRN filters for protection on military vehicles and other applications. The filters contain a HEPA section, better than 99.997% efficient against BS3928 Sodium Flame for the removal of biological agents. And a specially impregnated carbon section for the removal of nuclear/chemical vapours and gases.

Since 2009 EMCEL have been independently testing materials in order to satisfy the requirements of AEP54. As a result of this work EMCEL meets the gas test requirement of AEP54, Version B, Edition 1 (October 2014) for all essential contaminant levels and desirable levels.

EMCEL have logged new Nato Stock Numbers for our AEP54 compliant Vehicle Filters.

The NSN number that corresponds with the EMCEL manufactured CV90 Filters is 4240-99-250-3437.

The NSN number that corresponds with the EMCEL manufactured No.1 Filters is 4240-99-176-1162 .

EMCEL also produce Training filters utilised to run normally when CBRN protection is not required. Utilising Training filters for testing, training and in no-threat situations reduces the usage of real filters, thus giving considerable  cost savings. Features include replication of weight, pressure drop and optional HEPA filtration if required. Other options are available such as:

  • Alternative designs
  • Reduced Flow Versions
  • Panel Filter options


Filter options currently include UK No.1 Vehicle Filters and Filters compatible with CV 90 and CV 170 CBRN Systems utlised by NATO forces.
