summarize
SF6 gas mask (Winfoss-G11) is a single-eye mask filter type gas mask, a personal protective equipment, which is specially introduced for the personal safety of SF6 electrical equipment installation, commissioning, operation and maintenance, testing and overhaul personnel at the site. It can protect the respiratory organs, eyes and facial skin of the above personnel from toxic and harmful substances such as hydrofluoric acid, sulfur dioxide and low fluoride in SF6 high-voltage electrical appliances, and achieve effective protection. The mask has been inspected by the National Labor protection products Quality supervision and Inspection Center and has obtained a safety inspection certificate, which is in line with the relevant provisions of the national standard GB2890-82. The mask is composed of a mask and a canister. The mask can be used in direct connection with the canister. The anti-virus principle is: when the person inhales, the infected air is purified by the filter tank and then enters the human respiratory system through the mask.
The Winfoss-G11 gas mask provides superior durability and safety for difficult tasks requiring facial and respiratory protection. The standard thread design allows you to choose a variety of filter tanks to protect against gases, organic vapors and particulates according to your individual needs. After a period of use, you can also purchase SF6 special filter tank as a spare part to replace the original filter tank.

Structural principle
l Mask unit
The mask is a new single-eye comprehensive cover, which is composed of a cover body, a water blocking cover, a one-way check valve and a breathing talker.
The cover body is made of rubber molded as a whole, and the mask close frame adopts a folding side belt, which has a certain arc, and forms a similar air cushion tube when worn to ensure comfort and air tightness under various conditions of use. Three-dimensional headband structure, the headband ring adjustment is flexible and reliable, can be freely adjusted according to the user's head type, to meet the needs of various wearers. The eye window uses a single large lens with high light transmittance, which has a wide field of view and good visual performance. The mask is equipped with a water blocking hood and a one-way check valve. When inhaling, the air filtered through the tank enters the respiratory system through the one-way check valve of the water blocking hood. When exhaling, the one-way check valve is closed, and the exhaled humid gas is discharged from the breath valve. Improved window protection performance.
Breathing talker breath valve, suction valve, talker in one, compact structure, can be disassembled, easy to clean up stolen goods or replace. The speaker has clear sound transmission and small sound transmission loss.
l Filter tank unit
The shell of the filter tank is made of metal material, and the tank is equipped with special impregnated activated carbon and F-03 molecular brush composite adsorbent, and it is also equipped with mesh board, gauze, wool felt, which can effectively adsorb hydrofluoric acid, sulfur dioxide, sulfuryl fluoride, disulfide decafluoride, dust and other toxic and harmful substances to achieve the purpose of purification.
