Structure and features
MF22 type gas mask is a head-band type mask, including three types: large, medium and small. It is equipped with a talking device. The sealing frame is provided with a reflex-edge structure, with the features of comfortable to wear and good air tightness. Lens is reinforced by polycarbonate surface coating and anti-fog treatment, with good light transmission and good optical impact resistance. The cover body is made of high quality chlorinated butyl gum, with good properties of antitoxic droplet penetration and anti-washing performance, and can be used in combination with chemical protective clothing.
The mask interphone system is adopted with the form of dual interphone. The main interphone is integrated with the breath valve and drinking water device. The breath valve is easy to be removed to facilitate removing dirt on it. The drinking water device is easy to be operated and the main interphone has small sound transmission loss. The secondary interphone is mounted on the right cheek of the mask and can be matched with the communication equipment.
