HDT’s M48A1 Gas/Particulate Filter is self-contained with both the gas and particulate filter elements housed in one canister, limiting exposure to toxic gases and particulates when removing an M48A1. This simplicity and its 28.8 lbs (12.9 kg) weight allow for one person to easily handle the filter. The filter employs a glass micro-fiber particulate medium per MIL-F-51079, which removes biological agents, chemical agents in aerosol form and radioactive particles and is 99.97% efficient for particles of 0.3 microns. The M48A1 is compliant with the requirements of AEP-54 and utilizes ASZM-TEDA 12 x 30 activated carbon to adsorb toxic warfare agents in vapor or gaseous form. The filter canister is packed in a hermetically sealed shipping container for transport and long-term storage.

  • The M48A1 is a versatile and easy-to-use CBRN filter in wide use by the U.S. military and its allies. A 100 CFM (170 m3/h) medium airflow rating and the filter’s modularity make it ideal for positive-pressure systems in vehicles, vans and mobile shelters. Tested, qualified and field proven, the M48A1 filter set is currently used in a variety of vehicle applications and is employed on the M93 filter system used on HMMWV-mounted command and control type shelters such as the S280.

  • 100 CFM (170 m3/h) airflow
