The filter elements were notoriously difficult to change, often taking 15 to 20 minutes to complete the task. [9] This contract was to help design the drinking and resuscitation assembly that would be used on this new mask. For service members that require corrective lenses, two types of optical inserts were developed for the M17 series mask. or Best Offer. M6A2 hood, waterproof bag. The NAAK was issued when there was a likelihood of a nerve agent attack. It may also exchange with a less harmful substance at this site. Web$24.99 U.S. MILITARY M17 Gas Mask Filters - 1 Set Unopened, vacuum sealed set of military filters for the US M17 gas mask. brass fasteners. When the reactive substance comes in contact with the resin, it will bond to it, removing it from the air stream. Westinghouse personnel met with persons from CRDL (Chemical Research Development Laboratories) to review CRDLs work so far on the project. The cap did not work with the older style canteens when introduced due to a threading mismatch but worked with all modern U.S. Army one-quart and two-quart canteens. Because of this, the inserts do not offer ballistic protection. WebGI M17 Gas Mask Filters CH_MA200 $12.95 Add to Cart U.S. G.I. U.S. Military M17 Series Gas Mask Parts The gas masks became as uniform as the students' uniforms. This item was a late Vietnam era accessory for the M17A1 that made it possible to use a headset with a semi-integrated microphone that would be attached to the front of the mask. Though it was crude, the hypo helmet was a stopgap measure for British troops in the trenches that offered at least some protection during a gas attack. Filters against specific chemical agents can last up to 20 hours. There are two main difficulties with gas mask design: A primitive respirator was designed by Alexander von Humboldt in 1799 for underground mining, Various gas masks employed on the Western Front and Eastern Front during World War I, Finnish civilian gas mask from 1939. [21] Another early design was the "Safety Hood and Smoke Protector" invented by Garrett Morgan in 1912, and patented in 1914. Thus a resin can be tailored to a particular toxic group. These offered the same amount of protection as the later M6A2 hoods though were found unsatisfactory due to the lack of vecro adjustments and the lack of a zipper for ventilation which lead to the development and introduction of the ABC-M6A2 Protective Mask Hood in around the mid 60s. The M17A2 is shown above. Due to this problem, the resuscitation system was dropped with the design of the M17A2. These include: Similar to the ABC-M17 but made of a light grey rubber and a different outlet valve cover assembly. +$13.50 shipping. August 1975, 50 pages, 4" x 5-3/4". Likewise, the M13 series filter elements will not fit into any of the M17 series clones.[17]. They very quickly were adopted as a standard issue accessory to be used at all times on the ABC-M17 as a type of ballistic outsert to help protect the masks lenses from damage. Although thorough training and the availability of gas masks and other protective equipment can nullify the casualty-causing effects of an attack by chemical agents, troops who are forced to operate in full protective gear are less efficient in completing tasks, tire easily, and may be affected psychologically by the threat of attack by those weapons. Product Reviews. $19.92. Filters will fit US M17 gas masks. The M1 (E49) drinking system designed for the M17A1 is believed to be the first in the world, followed shortly thereafter by British and German designs. ADDRESSES ONLY! The left and right filter elements had to have a breathing resistance of plus or minus 5 mm of water to be considered a matched pair. It was a simple device consisting of a cotton hood with two hoses which hung down to the floor, allowing the wearer to breathe the safer air found there. Language links are at the top of the page across from the title. [13], The filter element pouches on the mask were closed with a series of plastic dumbbell-shaped buttons and buttonholes in the rubber of the face blank and nose cup assemblies. This purpose for the extra-small M17A2 was eventually phased out when the extra small M45 was fielded as part of the Land Warrior program. Drager 40mm NBC Gas Mask Filter Canister, Unused Military Surplus . It also should be noted that very early examples of inlet valve assemblies would have a little metal tab molded to the cap frame to help with easy removal of the caps.

A modern mask typically is constructed of an elastic polymer in various sizes. It was designed to protect the valve disks from freezing in environments below freezing, usually at below 20 degrees Fahrenheit (-30 Celsius). The 3 models and the canteen were studied by CRDL personnel and their comments on the design were: In answer to the first objection, the Second Developmental Model will incorporate a shutoff valve of a rotary style action. The M17 series mask design was copied in at least four countries. There are lightweight masks solely for protection against riot-control agents and not for NBC situations. This allowed copper ions to migrate into the rubber around the hardware of the mask making the rubber weak and brittle. Tracking and insurance are optional. (later on was used to store the M1 waterproofing bag) The carrier also had a small snapped pouch on the rear to accommodate the M5 treatment set and later on the M13 and later M258 personal decontamination kits. These inserts were used for day use only. This model had both the Drinking coupling and resuscitation system set up as two different systems that each had their own tubes instead of a singular Mouthpiece like on the Westinghouse model. [7], A filter type that can protect against multiple hazards is notated with the European symbols concatenated with each other. The mask was stored in the carrier with eye lenses facing the opening of the carrier with the head harness folded inside of the mask and the hood stored inside out to facilitate the rapid donning of the mask if installed. The ABC-M17 was used by civilian law enforcement agencies for crowd control operations when protection from tear gas was required. Later versions of the mask carrier were made from a water-resistant nylon material. This design was also not considered satisfactory due to the fact the mouthpiece remained in the user's mouth at all times. Although there was little risk of the use of lethal chemical warfare agents by either side, the American Army made extensive use of riot control agents (most commonly, CS) during certain missions. For non-particle hazards, the level "1" is assumed and a number "2" is used to indicate a better level. Panoramic lenses were not popular until the 1930s, but there are some examples of those being used even during the war (Austro-Hungarian 15M). These are new in the original wrap and dated 1972. Specially outfitted Soldiers would then clear the tunnels of enemies and booby traps. Such lack of instructions can only increase the appreciation for today's included instruction manuals on a lot of filter packages. [13] Each wipe was labeled as either "1" or "2." The Rotary-Actuated model also had problems with the rotary lever being difficult to operate, though it was still preferred over the Push-Pull design. Some masks have one or two compact air filter containers screwed onto inlets, while others have a large air filtration container connected to the gas mask via a hose that is sometimes confused with an air-supplied respirator in which an alternate supply of fresh air (oxygen tanks) is delivered. The second type attached to the area where the eye lenses met the face blank with a set of prongs. WebProduct Overview The M17 gas mask was the primary mask issued to US troops in the 1960s, 70s and 80s. The mask carrier had fiberboard stiffeners sewn into the sides of the pouch to add to the structural integrity of the bag. It was used up till the 1980s. Sure you can get a U.S M9A1 from the 50s and wear it fine. They had ended their contract by 1964 leaving MSA as the only remaining manufacturer of face blanks. Isoamyl acetate, a synthetic banana flavourant, and camphor are often used as innocuous challenge agents. However, if the mask is for a particular use (such as the protection from a specific toxic material in a factory), then the design can be much simpler and the cost lower. The cloth was to be taken out of its container after you moisten the inner surface of the masks lenses with your fingertips. During the Cold War, it was seen as inevitable that there would be a constant NBC threat on the battlefield and so troops needed protection in which they could remain fully functional; thus, protective gear and especially gas masks have evolved to incorporate innovations in terms of increasing user comfort and compatibility with other equipment (from drinking devices to artificial respiration tubes, to communications systems etc.). [13], The filter elements were composed of lightweight gas-aerosol filter material that fit into cheek pouches of the mask. Crucially, it is connected to a filter cartridge near the mouth either directly, or via a flexible hose. Filters will clog up, substrates for absorption will fill up, and reactive filters will run out of reactive substances. While more comfortable for the wearer, the design was rejected since there was the concern of penetration of liquid persistent chemical warfare agents such as VX. This filter provides single-stage filtration through application of a composite material consisting of fine particle size impregnated activated carbon (for vapor filtration) mixed with glass and polymer fibers (for aerosol filtration). THE FILTERS ARE NOT RETURNABLE. A early M17 Mask Carrier worn in the hip carrying configuration. This was coupled with a tube that extended outside the mask with a quick disconnect assembly on the end to attach to a specially modified canteen with a hose extension so the wearer could drink from the hip.
