If it were to sit out of the can and you don't use it it would take a long time for it to deteriorate.

This one does not have a second skin. Price includes free second skin.Stemming from one-mask joint branch development experimentation in the early 's, the M45 initially sought to replace all masks in service with the U.
Armed Forces, but due to logistical and ultimately legal issues, only entered service in the aforementioned roles. It is notable that all plastic parts of the mask are ultrasonic welded, a process which has never been applied to a protective mask in the past.
After the Gulf War, the U. V Masks. The main gas mask design that rose out of the program was the XM44 Series. It used a sleek, black silicone facepiece with side canister ports, central voicemitter, and rubber-shrouded outlet valve assembly with integral drinking tube. The most unique feature of the XM44 series was its small, elliptical lenses, similar to the M43's, which were positioned close to the eyes to offer peripheral vision while allowing for integration with optical instruments, such as the novel Helmet-Mounted Display Systems being tested during SIPE.
The masks came standard with a brown butyl-coated nylon protective hood with integral butyl secondary skin, a pair of lens outserts, a C2 Canister, and occasionally an M15A1 Carrier Bag, similar to that used by the M17 Series. Additionally, some models of the XM45 lacked lens crimping and used glued-in lenses, similar to the M43, while others such as the RPD modified a basic XM44 by adding a shrink-wrapped coating over the lens crimping to better interface with optics and resist debris.
Like older prototype masks, a variant existed for several basic military roles:. Notice the metallic hardware and lack of lens frames. Glued-in lenses were a design feature carried over from the M43 Series Masks. Initially, the XM45 was nothing more than an XM44 Facepiece with glued in lenses, hose assembly, and integral mic. As work progressed on the design, the molds were updated to incorporate larger eyepieces and a more streamlined arrangement of valves and voicemitters.
The design continued to be tested and evaluated with little to no change to its overall hardware and function until the mid's, when a major overhaul of the design came about. A display model XM45 XM47 'Land Warrior' Configuration made of transparent silicone, in order to better show off Campbell's unique 'sonic-welding' process.
Notice the Optical Inserts. Army since September After a long series of trial and error, Campbell had designed plastic components for the XM45 mask to replace the bulkier integrally-molded metal ones, not only reducing weight, but also production costs. A unique ultrasonic welding process was developed that melted the components together on the facepiece using a high frequency vibration. Final production and assembly was carried out by Campbell Plastics while the silicone faceblanks, nosecups, and butyl secondary skins were molded by the West American Rubber Co.
The plastic components were molded from M. Hanna Co. These new, upgraded plastic components were a grand departure from the previous aluminum crimps and milled components of past U.
Campbell was respectfully very protective of his innovations, and filed a patent for the XM45 Mask. However, Campbell's reports to the Army throughout the duration of development were failing to meet the "release of invention" demands, and the act of patenting his invention sparked a long legal battle over the rights to the XM45's sonic-welded technologies. It was at this point, the Army began to dispute the terms of Campbell's patent, claiming a joint ownership of the concepts, having been developed under government funding, and the patent rights were forfeited to the U.
On March 14,Richard Campbell appealed to overturn this decision, claiming that he had, in fact, disclosed all available details of the invention albeit not in the form of a DD Formas was outlined as a requirement by his contractand that the forfeiture of the patent should not be determined by favoritism, especially "where the government suffered no genuine harm".
Overall, the object of Campbell's appeal argued that any actions against the terms of his contract were not grounds to forfeit his patent. The board ultimately rejected Campbell's appeal, ruling that Richard Campbell had failed to satisfy obligation of reporting to the Army that his sonic welding process was regarded as an invention.
Further stating that any full details received as a result of the Army's study of Campbell's patent or release of field reports was not as a result of Campbell's cooperation. Consequentially, the board also found that in accordance with FAR Les Brownlee, Acting Secretary of the Army was closed. Production of the M45 Mask from hence onward was handled entirely by the Government.
The Air Warrior kit can readily be identified with the use of a standard Non-Metallic M42A2 Hose with a small OD Webbing Strap on the Canister end, as well as a unique accessory known as a 'canister baffle' - a ventilated plug for the C2 or C2A1 Canister that prevents gear or clothing from inhibiting the air intake. On occasion, the M45 Air Warrior Mask can be seen using the Racal LWPAPR, a unique and compact blower unit assembly, in the form of a rubber cup with a blower fan and motor that fits snug over the canister assembly.
Stemming from the abandoned 'XM47' designation, while the main and primary adopted role of the M45 was as a modern aircrew protective mask system, the M45 CB Mask saw a considerable amount of testing with U.
Army ground forces as a part of the then-ongoing Land Warrior program.The M40 field protective mask was one of various protective masks used by the United States Armed Forces and its allies to protect from field concentrations of chemical and biological agents, along with radiological fallout particles. It is not effective in an oxygen deficient environment or against ammonia. The M40 was the result of a program in the s to develop a successor to the Mseries protective masks which had been in service with the US armed forces since The M40 was to be a return to conventional protective mask design with an external side-mounted filter canister, rather than the internal cheek filters of the M17, which were awkward to change, especially in a contaminated environment.
The final prototype, the XM40, was approved for service and then designated the M The M40 was phased into service with the U. Air Force and Navy. However, both masks suffered from the inadequate protective capabilities of their face pieces, which was of a silicone rubber susceptible to corrosion from blister agents. The M42 series masks are a variant of this mask with alterations that make it better suited for use by armored vehicle crews, who have to connect their masks to and draw air from their vehicle's own filtration system.
The M40 field protective mask is currently being replaced by the M50 joint service general purpose mask. Embassy 's Mutual Logistics Support Agreement program.Elicenser too old
The M40 field protective mask features three voicemitters, one on either the right or left side, and one in front. A voicecom adapter may be placed over the front voicemitter to amplify the user's voice. The mask can be adjusted in the field to accept the filtering canister on either side, so that a weapon may be shouldered.
Right-handed shooters will normally locate the canister on the left side of the mask and vice versa. The C2 canister on the M40 mask can protect the user from up to 15 nerve, choking, and blister agent attacks, and two blood agent attacks.
The M40 comes with a drinking system that allows the user to drink water after donning the mask for long periods of time in a chemically contaminated environment. In order to use the drinking system the user must also have suitably equipped canteen lids or an adapter for other containers. From Wikipedia, the free encyclopedia.
