Description

1.Applications and feature

The Gas mask with drinking water equipment components is a novel design gas mask, whose canister is connected directly to the face piece. When the air is a contaminated NBC agent, the gas mask provides effective protection to the wearer’s respiratory organs, eyes and facial skin. The gas mask is designed for the military, police and civil defense and can also be used in industry, agriculture, storehouses, scientific research work, etc.

The flexibility of the face piece is suitable. The straps of elastic webbing have good elasticity and can be adjusted at random to ensure a comfort, gas-tight fit. The large triangular lenses are manufactured from optical plastic and surface-treated specially. The single-piece lens provides a wider visual field and more excellent optical properties and good abrasion and shock resistance.

The canister is filled with good quality impregnated activated carbon and smoke filter made of high efficiency filter paper, and can remove toxic gas and particulate aerosol from the incoming air except carbon monoxide. The canister has a low resistance and lightweight.
