HDT's M48A1 CBRN filter canister is the most versatile and easy-to-use CBRN filter in wide use by the U.S. military and its allies today. Its 100-cfm medium airflow rating and its 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. The M48A1 is also the filter employed on the M93 filter system used on HMMWV-mounted command and control type shelters like the S280.
The M48A1 is a self-contained filter, with both the gas and particulate filter elements housed in one canister. This limits exposure to toxic gases and particulates when removing an M48A1. This simplicity and its 28.8-lb. (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 .3 microns. The M48A1 utilizes ASZM-TEDA 12x30 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.
HDT filters are assembled and tested using strict lot controls to ensure product quality. Each production lot of filters is sampled for live-agent testing. These controls provide the highest quality chemical and biological protection available today.
