Gas Mask

1 Application and Feature:

The XF0013MF11 mask is a novel design gas mask,the canister of the face piece. when the ambient air is contaminated with chemical biological and radiation agents, the mask can provide effective protection to the we-area’s respiratory organs, eyes and facial skin. The mask is designed for use by military, police and civil defense and can also be used in industry, agriculture, storehouse, scientific research etc.

The mask is equipped with a drinking system. If necessary the face piece may be connected to a canteen by means of accessories to enable the wearer to intake water or fluids in contaminated areas. The flexibility of the face piece is suitable. The elastic straps have elasticity and can be adjusted at random to ensured a comfortable, leak-free fit. Large triangular lenses are manufactured from optical plastic and surface treated specially. The lenses provide a wide visual field and excellent optical properties and have good abrasion and shook resistance.

The canister is filled with impregnated carbon of good quality and high efficiency filter paper and high efficiency filter paper and can filter out toxic gases and particulate aerosol from the influent air except carbon monoxide. The canister has a low resistance, lightweight and long life.

3 USE AND MAINTENANCE

(1) The XF0013MF11 mask is divided into three sizes (small, medium ,large on the left lower part of the face blank with a number:1(small),2(medium) or 3(large).The user chooses a suitable mask according to the user’s head shape. If the user’s eyes after the mask has been worn are at the level of about10 mm above the horizontals center line lf lenses , it is shown that the selected size of the mask is suitable. If the eyes are above the value of 10mm,the mask is too small . If the eyes are below the value ,the mask is too large.

(2) Use of drinking device. A special canteen cap should be screwed previously to the canteen .when the wearer needs to drink water ,unscrew the protective covers from the canter-en cap and the water inlet valve, screw the ends of the connecting tube to the canteen cap and the water inlet valve, actuate the water inlet valve by hand to keep a suction tube in the mouth.

3,The complete mask, particularly the lenses and the expiratory valve, should be kept clean. If necessary the lenses and the expiratory valve may be washed with clear water.

4,the canister can diversities adsorption capacity for toxic gases after it has absorbed the moisture. The closure cap and the plug should usually be attached to the canister to prevent the ingress of moisture.

5,The gas masks should be stored in a cool dry place. If the masks are not in use for a longer time, a support should be placed in each face blank to prevent the deformation. The face piece must not contact organic solvent.
