History Edit

The Avon S10 is the predecessor of the Avon FM12 and was the replacement mask for the S6. The S10 was used as a CBRN protective mask for the British police and military.

The Kit Edit

The S10 kit comes with two vacuum sealed NBC filters, a haversack/carry bag, a canteen adapter lid compatible with the drinking hose), chemical detection papers, an S10 manual, an NBC survival booklet entitled "Survive to Fight", cotton glove liners and rubber chemical gloves, and a bottle of decontamination powder called Fuller's earth. Weight 950g. Spare canister weight 225g. DKP No1 Mk1 105g. Autoject (Combopen) x 3 = 100g. Carrier 305g.

Design Edit

The S10 is made of a thick black rubber which is extremely durable and has a 20 year service life from the date stamped on the mask.  

The S10 features two voice diaphragms which are located on the front of the mask and on either the left or right hand side of the mask depending on whether the mask was manufactured for left or right handed shooters. A microphone made specifically for the S10 clips onto the secondary voice emitter and interfaces with the Clansman radio system. The lenses on the S10 are almost identical to that of the Canadian C4 in that the "face" of the lenses are flat and a plastic ring keeps the lenses locked in place.

The exhale valve is also located in the middle of the mask and is found in the same assembly as the primary voice diaphragm. The S10 is STANAG 4155-compliant which means the filter thread is the standard 40mm thread diameter and pitch. This means you can use any filter utilizing NATO 40mm threads. The S10 also features a drinking tube that can be adjusted from the outside of the mask; by spinning a flat piece of plastic near the voice diaphragm you move the straw on the inside of the mask from the side to the middle of the mask making it far easier to access the straw while the mask is worn. This system ensures the inner straw isn't in the way of the wearer. The drinking straw is wrapped around the primary voice diaphragm/exhale valve assembly and then inserts into a holder which stops the straw flapping around and getting in the way while the mask is worn.

The S10 has a ridge running around the edge of the mask to form a tighter seal with the hood of the Mk4 NBC smock and its successors.

Using Prescription or vision correcting lenses Edit

There was an alternate lens style available for wearers of glasses and other prescription lenses. This alternate lens style had the addition of a clip in the flexible plastic lens retainer which allowed the fitting of prescription lenses. The prescription lenses were specifically supplied by unit medical centres to individuals requiring these lenses. Prescription lenses were only fitted and replaced by qualified NBC instructors using the S10 maintenance toolkit. The prescription lens fitting did have the problem of trapping fullers earth between the respirator and prescription lenses which would further restrict vision during NBC environment training.

Accessories Edit

The S10 mask has a number of accessories available such as tinted black flash lenses (ballistic outserts), a Nomex fire resistant hood, red light enhancing lenses (for use at night), laser rejection filters/lenses (to stop lasers blinding you), a microphone, and a hose. Outserts are the most expensive accessories around, whereas microphones are relatively inexpensive.

Current uses Edit

The S10 is being replaced by the British MOD (Ministry of Defense) with the more modern General Service Respirator (GSR)  manufactured by Scott Safety. (Currently underway - 2014)

Successors Edit

The FM12 is an overall upgrade of the S10 and there are several differences between the S10 and the FM12. Some of those differences include a smaller exhale valve/voice diaphragm assembly on the FM12,  a longer drinking tube on the FM12, and on some FM12s the secondary voice diaphragm can be unscrewed which enables filters to be placed on either the left or right hand side of the mask or to be removed completely to accommodate another filter (two filters are usually used in highly contaminated areas). Although the Avon FM12 was never used by the British military officially, it was (and still is) used by numerous law enforcement agencies and military forces all over the world.

It is worth noting that a mid life redesign that brought in a few modifications were carried out to the S10. The inhale and exhale valves were replaced with a different specification of rubber. A new design was brought in that more effectively held in the place the harness straps

Variants Edit

There were several alternative versions of the S-10 Made, each intended for different purposes, with the masks being modified to suit that purpose better than the S-10 in its 'stock' state.

AR-10 Edit

This mask is similar to the S10, however it doesn't have a drinking tube and it has flat polycarbonate eyepieces. The AR10 polycarbonate eyepieces which are a lot stronger than the brittle plastic lenses on the S10 and they also provide a greater field of view. Also, the AR10 is a dual port mask, with a blank plug used to block the unneeded port.

N10 Edit

Like the AR-10, the drinking tube is absent, and the lenses are flat polycarbonate. The exhale valve cover, lens frames, inlet, blanking plug (instead of secondary speech module) and strap fittings are all grey plastic. Some models have been fitted with a white exhale valve cover. The head harness is made of thicker rubber.[1][2] The mask has been seen in use by nuclear reprocessing staff at Sellafield.

SF-10 Edit

The SF10 is made for special forces such as the SAS and many police/ LE agencies. It is identical to the AR10, except the Sf10 has a blank plug to block unused port.

SF-10IM Edit

The SF-10IM is a very rare variant of the SF-10 that has a microphone built in to the mask in place of the drinking tube on the S10.

Foreign Copies And Export Models Edit

Due to the S10's successful reputation, at least two countries currently developed their own copies of the S10. Most likely under license. These include Pakistan and China, however some models have been exported to other countries.

MF-10 Edit

A rather rare export model of the S10, redistributed by KX Defense[3][4], an American company. Its key difference is that the mask was pre-packaged with a six-point elastic head harness, seen on most US military masks, unlike the standard rubber one used on the original. While it was designed for law enforcement agencies within the US, it still retained the drinking tube, overall it's just the standard S10. Meaning it is compatible with most, if not all of its accessories.[5]

PAK-10 Edit

A licensed and direct clone of the Avon S10, in service with the Pakistani Armed Forces.

PAK-10 Twin Edit

The same as the mask mentioned above, but has dual filter ports for heavy decontamination and possibly to accommodate left handed shooters.

SD-10 Edit

A licensed and direct clone of the SF-10, possibly issued to Pakistani special forces and/or police.

MF-22 Edit

The Chinese clone of the S10, which features a different voice diaphragm and exhale valve assembly, as well as a different exhale valve cover. Currently in service with the Chinese PLA. There is a version designated as MF-22A, which is the same as the original, but features dual filter ports.
