Description
WITH-CHEM OM-90 gas mask – Developed for the benefit of the Czech forces, designed for use in hostile zones, within integrated units. Designed for use with weapons and optics, provides protection of the respiratory tract and face against toxic NRBC agents (vapours, gases, aerosols, contaminated dust) in conjunction with either filter cartridges or a powered respirator.
CE standardized mask EN 136: 1998, class III & EN 148-1 (thread), manufactured from bromobutyl rubber (vulcanized polyisobutylene) - maximum impermeability to TIC (Toxic Industrial Chemicals) and CWA (Chemical Warfare Agents), excellent thermal and mechanical resistance. Hypoallergenic silicone internal half-mask, perfectly waterproof - no fogging, even with sustained effort - significant reduction in the presence of CO2 in the mask & low mechanical resistance to inspiration / expiration (physiological constraints of the wearer greatly reduced ).
Two side threads (40 × 1/7 “ – 40mm NATO standard) allow the addition of two filter cartridges simultaneously – depending on the saturation of the atmosphere with toxic agent – or with a single cartridge (the second thread then being locked and sealed). The hydration system – which allows you to drink in a contaminated area – is immediately operational (a bottle is provided with the mask).
The communication system allows understanding of 95% of voice exchanges - up to a distance of 2 to 3 meters, without sound distortion. The mask is attached to a head harness (rubber & textile) - suitable for ballistic helmets, integration of eyeglasses (not included) in the mask compartment if needed, sweat evacuation via the exhalation chamber (allows for long wear).
LIFETIME: 20 YEARS / MANUFACTURER WARRANTY: 05 YEARS
