Hose Assembly: The hose assembly provides a connection between the mask and the vehicle collective protection system. When the mask is worn, the filter element stuck out of the face blank of the mask and became a natural "lever arm" that could break the seal of the mask when working in confined spaces or simply through the rigor of combat operations. The FM50 is identical to the M50 and intended for allied military sales. endstream endobj 288 0 obj <> endobj 289 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text/ImageC/ImageI]/XObject<>>>/Rotate 90/Type/Page>> endobj 290 0 obj <>stream

The face blank has an inverted peripheral face seal and an integrated chin cup and is available in four sizes with interchangeable silicone nose cup for a custom fit. The nose cup assists in controlling the flow of air throughout the mask to minimize the fogging of the eye lenses during breathing. In the mid-1990s, the M40 series masks were replacing the old M17 series throughout the armed forces of the United States but CBDCOM (later SBCCOM) was already looking forward to the next mask series. Filter alignment marks are molded into both the M61filters and the facepiece assembly to ensure the proper attachment.

Secondary Filtration Media - No one filter media formulation can protect against all conceivable threats at the same time, so an additional filter is being developed to augment the standard M61 filter for specific missions. Current filter developments include: An add-on secondary filtration element seen attached to the standard M-61 filter element. It should be noted that the filter elements do not contain hexavalent chromium as some previous filter media formulations have. These ingredients are toxic and can cause mucous membrane irritation, but are safe as long as the shelf life indicator patch is not disturbed. M61 (Twin Low Profile) There Are Slight Variations Between Each Mask, Such As The Thread Color And Color Of The Back, Typically Worn On Uniforms, Bags or Helmets. Succeeded by Evolving protection capability to meet the operational needs of the tactical operator has meant Avon Protection are the market leader among Law Enforcement and SWAT users around the world. PAPRs have air blowers to pull air through the filters and deliver the purified air to the mask wearer.

[4] The foreign military sales version of the M50 is the FM50. The closed-circuit type filters, supplements, and recirculates exhaled gas commonly called a "rebreather."

Installation 1.

This configuration combines the tank supplied air of the SCBA with the air blower capability of the PAPR to minimize the stress on the wearer on long-duration missions in a contaminated environment.

The mask  features a variable resistance exhalation unit (activated with a simple twist of the outlet valve assembly) that allows for the following modes of operation depending on the specific mission: This protective mask was developed to counter the multiple threats encountered on the modern battlefield, war on terrorism and peacekeeping operations around the world. Ability to safely and quickly change filters while in a contaminated environment. Although the issue has generated some internal criticism and may complicate NATO interoperability and logistic issues, the US decided that the benefits of the non-standard filter design outweigh the benefits of NATO standardization. The mask was designed to incorporate state-of-the-art technologies to protect US and allied forces from current and anticipated CBRN threats. Filter The decision to move to the large external C2 and C2A1 filter elements for the sake of NATO standardization made the mask bulkier (although lighter) than its predecessor, the M17.

The "How To" video series provides audiences the opportunity to get an inside look at how Marines train and go about their daily activities. The clear outsert is issued with an outsert pouch which can also be used to clean the mask. The adoption of the M61 series filters departed from the Standard NATO Agreement (STANAG) governing NATO filter sizes (STANAG 4155) that require a 40mm screw-mounted filter with a 1/7 turn ratio. The facepiece assembly incorporates a flexible, single, polyurethane eye lens; a front module that provides a direct speech capability and integrates the exhalation disk valve, drinking system components, and communications interface; two filter mounts (left and right) that integrate the air inlet/outlet disk valves, self-sealing disk valves, air deflectors; and a nose cup that controls the flow of air throughout the mask. h�bbd``b`�$B���+$؎ ��X��jL� ى@��&F�u m����� 0 ^

ARZ-CoZZAT Sorbent - Researchers at Defense Threat Reduction Agency combined current M61 filtration materials with two new sorbents; ARZ, primarily composed of zinc chloride, and a metal oxide composite made of cobalt (Co), zinc (Z), silver (A), and triethylenediamine (T) additives (CoZZAT)  in a tri-layered M61 filter bed to improve toxic industrial chemical and chemical warfare agent protection. 22 CFR 125.4(b)(5) applicable. The M61 filters contain activated carbon media and a high-efficiency particulate filter. The facepiece assembly is made of chlorobutyl rubber-silicone blend giving the mask a high degree of flexibility and comfort for extended use. The hose is attached to the service member's uniform using the Clothing Clip to prevent the hose from pulling the mask away from the face.

By ordering this item, customer warrants that they have the required training and authorization to use this item. There are two mask variants: the M50 (ground and shipboard use) and M51 (ground vehicle use). Take your favorite fandoms with you and never miss a beat. The development of the M61 filters continues as new technologies, materials, and manufacturing techniques emerge. The 53-Series Protective Mask was specifically developed to meet the unique requirements of Special Operations Forces (SOF) and is not a standard mask issued to other service members. Fully integrate the mask into the warfighter's combat ensemble for the next generation. Microphone, Microphone Adapter, and Communications Lead: The microphone is attached to a microphone adapter that is attached to the communications port in the front module main body inside the facepiece assembly. *Venture Surplus is closed on all federal holidays, please use email to contact us on those days. Also The additional filter simply clips onto the current M61 filter and provides an extra layer of protection for specific threats.

Your email address will not be published. High-Efficiency Synthetic Particulate Air (HESPA) filtration material - HESPA offers several advantages to the current M61 filter program. JSLIST, night vision devices, optical sites, helmets, etc.. Reduce the size of filter elements and shape it in different configurations to fully integrate it into the mask. M40MCU-2/PM45 The filter can be used on either side of the mask to accommodate left and right-handed wearers. PAPR (Powered Air Purifying Respirator). Nose Cup Assembly:  The nose cup assembly is located inside the facepiece assembly. Unlike activated carbon, which traps poisons via relatively weak physical adsorption, CoZZAT filters these molecules by reacting with them chemically with strong covalent bonding. It provides excellent protection against traditional chemical and biological warfare agents, selected Toxic Industrial Materials (TIMs), selected Toxic Industrial Chemicals (TICs) and particulate matter including radioactive dust.

The facepiece is designed with an inverted peripheral face seal and an integrated chin cup.

Venture Surplus assumes no liability for its misuse.

Additionally, economies of scale could significantly lower costs if all armed service could use the same mask system instead of having many models spread out among the services. A mask that could filter out common industrial hazards would greatly assist sensitive site exploitation and other military operations.

They serve as inlet disk valves and permit filtered air to enter the mask.

MCRD-CBRN-1001 Employ the Field Protective Mask (FPM), Medical Management of Chemical Casualties Handbook, https://gasmaskandrespirator.fandom.com/wiki/M50_Series?oldid=41177. Field of View The M61 substitutes a non-toxic zinc-based formulation to counteract cyanogen chloride and hydrogen cyanide gas (NATO designation CK and AC respectively). %%EOF Secondary filters are being developed for ethylene oxide, ammonia, and formaldehyde challenges. Consequently, there were few actual prototypes used in the development of the mask however, there were several mockups to illustrate different features for decision-makers.
