Industry processing, scene, mine, Petroleum Industry operation field etc. are given containing toxic and harmful or shortage oxygen
User brings the place of harm.According to the difference of operation principle, air respiratorresuscitator can be divided into positive-pressure type
Respiratory organ and negative-pressure type respiratory organ.Positive-pressure air respirator is the one of positive-pressure type respiratory organ, and filters
Formula canister respirator is the one of negative-pressure type respiratory organ.
Positive-pressure air respirator be utilize the self-contained clean compressed air of user as air supply source,
User does not relies on outside ambient air when using, and therefore uses safe class higher.But its shortcoming exists
In being affected by the source of the gas carrying amount entrained by user, generally use the time shorter, and again fill
Fill out source of the gas the longest.Particularly in fire control field, the most all can there be many fire fighters because entering
After entering fire scene rescue, the source of the gas carrying amount of respiratory organ is not enough and can suck a large amount of toxic gas or dense smoke, causes
The somatic damage that cannot retrieve even is sacrificed.
Filtermask is then to utilize canister to be carried out by the toxic and harmful in ambient air
Filter, be catalyzed so that it is arrive nontoxic rear suction.The shortcoming of filtermask is to filter poison
The kind of gas is limited by material filled in canister, so filtermask is commonly used to not
Anoxia and the preferable place of ambient air quality.
