The M48 Gas-Particulate Filter was designed by the U.S. Army as the NBC protective system of the Abrams A1M1 tank. It is a compact, lightweight, radial filter with a nominal flow of 100 CFM (2830 lt/min), constructed from aluminum alloy and coated with a special chemical resistant paint. Each M48 filter is packed in a hermetically sealed metal can ensuring a shelf-life of at least 5 years.
The M48 filter is also suited for use in armoured cars, troop carriers, riot dispersal vehicles, and mobile shelters. The production of the M48 filters is controlled by rigorous quality assurance tests and procedures complying with Mil- I-45208A. Each filter is tested for air flow resistance, aerosol penetration, R-12 freon leakage, workmanship and metal can leakage.
