Product model MF202
1. Purpose
The gas mask is a kind of filtered single-window personal respiratory protective equipment, which can effectively protect the face, eyes and respiratory tract of the wearer from the damage of toxic agents, biological warfare agents and radioactive dust. It can be used by personnel in different fields such as industry, agriculture, medical team and scientific research. It can also be used by the , and civil defense. When equipped with the electroacoustic call function, it can broaden the collaborative dialogue radius between personnel and achieve clear dialogue between personnel.
2. Composition and characteristics:
MF202 series gas mask is mainly composed of mask, gas filter, etc. The mask is mainly composed of high-quality rubber cover body (adopting injection molding process and surface sanding), lens, interphone and headband, and is mainly divided into four types according to different structures
Product model and structure characteristics
A Low resistance and long protection time of double gas filter tank
B Poison filter and drinking water device The drinking water device is easy to operate
C Double talker structure of gas filter tank, main and auxiliary talkers
D Poison filter and electroacoustic talker have voice amplification function
Features: The close frame of the mask is of anti-folded structure, which is comfortable to wear and has good air tightness, and is suitable for more than 95% of adults to wear; Rubber headband or mesh headband can be adjusted at will, with proper tightness. The mask eye window is made of PC material, and the surface is specially treated, which has wide vision and good optical performance; The duplex structure talker has obtained the national patent, and the sound transmission loss is small.
The electroacoustic talker has good ability of resisting environmental noise and electromagnetic interference. It has the voice amplification function, which can compensate for the loss of sound transmission caused by the gas mask, and can realize the clear dialogue between the person wearing the mask and the face. Ensure that the personnel can use the telephone and other communication equipment normally after wearing the mask to broaden the cooperative operation radius between personnel and improve the operation efficiency.
The canister is filled with high-quality activated carbon or activated carbon-catalyst, which can prevent different kinds of poisons, and has small resistance and light weight.
