The OM-90 is the current service gas mask of the Armáda České republiky (Army of the Czech Republic). Its production started in the year 1990. It comes in three sizes, with size 2 supposedly fitting 95% of the population.
Overview[]
The facepiece is made of bromobutyl rubber. It's lenses are two circular, forward-looking tempered glass eyepieces optimized for optical use. It features a drinking tube system which is compatible with the camelbak system, and a center primary voice emitter. Breaking away from the previous M10 and M10M series masks, the OM-90 has a textile 5-point head harness. The OM-90 also sports a dual filter port design. That being said, the filter(s) can be inserted on the left side, the right side, or both. Although, it is not uncommon to find the OM-90 with a free port and a plugged second one. It features an oral nasal cup and an inner rubber seal. The voice clarity through the emitter is over 95% (as stated by the maker) as one would notice, continuing the Czech tradition it is a clone of the Avon S10/FM12 mask with the eye pieces having slightly less peripheral and drinking system using the same push-pin style as the M17 (and subsequent M10/M10M clone masks)
Filter[]
The OM-90 is a STANAG 4155 compliant mask, and, when issued in military kit, comes with an OF-90 (Ochranný Filtr 90) filter
Kit[]
The kit consists of a rubberized bag with plastic rectangles in the sides for it to keep shape, manual, the OM-90 mask, OF-90 filter, drinking tube-compatible canteen cap, and an NBC suit, either the JP-75A, or JP-90. The masks are sometimes seen with vz.95 camo'd pouches, and even thought these pouches are made mainly for the civilian sector, soldiers do sometimes buy and use them.
