| 08The sealing frame of the mask is an arc-shaped folded edge, which is comfortable to wear and easy to be airtight. The mask material has excellent resistance to penetration of toxic agent droplets and washing resistance. There is a convex ridge on the outer edge of the mask body, which can match the gas mask.
The six headbands can be adjusted at will, but must be appropriately tight.
The two circular eye windows of the mask can match optical equipment. The lens is made of optical plastic, with a wear-resistant coating on the surface, and has good optical properties, impact resistance, and abrasion resistance.
The mask communication system is a double-talker form. The main talker is designed as a whole with the exhalation valve and drinking water device. The exhalation valve is easy to disassemble for easy cleaning of dirt. The drinking water device is easy to operate, and the main talker has a small sound transmission loss. The auxiliary talker
is installed on the right cheek of the mask, which can match the communication equipment.
The mask is equipped with a diversion water-blocking cover with two inner suction valves, which has good light-keeping performance.
The gas filter canister is filled with high-quality activated carbon-catalyst and high-efficiency filter paper, which can filter various toxic gases and particle aerosols except carbon monoxide.
