In December 2011, Avon Protection Systems, Inc. in Cadillac, MI won a 5-year, $176.4 million firm-fixed-price contract to make M61 filter canisters for the new M50 Joint Service General Purpose Mask. Work will be performed in Cadillac, MI, and is expected to run until Dec 22/16. The bid was solicited through the Internet, with 6 bids received by U.S. Army Contracting Command at Aberdeen Proving Ground, MD (W911SR-12-D-0001).
The new M50 mask is designed to be more compact, lighter, more comfortable and more effective than the older M40. When worn in conjunction with a MOPP suit, the mask allows over 24 hours of protection against chemical or biological agents and radioactive particulates. Improvements include a single cast, optically correct visor with a wider field of view than the previous twin-lens design, and a twin conformal filter for a 50% improvement in breathing resistance. Anyone who has ever tried heavy physical exertion in a gas mask understands how much that improvement means. The convenient integrated 3L Camelbak for drinking, and clip-on sunglasses or corrective lenses, will also be appreciated.
