Respirator Protection can be divided into 2 types, which are air pollution-free type. Before entering the air (Air purifying devices), including
1. Particle filter mask Serves to filter particles that are suspended in the air, including dust, fume, smoke
Air filter Consists of air filter materials (filters) that are commonly used. There are 3 characteristics:
Type is a sheet made of compressed fiber To be appropriate For filtering particles By providing maximum air filtration efficiency And the least resistance to inhalation The type of air filter material is contained in a loose cartridge. Suitable for dust filters High efficiency type By using air filter material That looks like a thin sheet folded up and down To be pleated in a cartridge To increase the surface area For particles to go to the island And reduce breathing resistance Standard type of dust filter See details at Particle filter standards Head strap which can be adjusted as needed In order to always fit the wearer's face There is also a particle filter mask. Disposable type The composition of the mask is the mask and the filter material will combine to the same piece. The upper part of the mask has a soft metal sheet. Which can be adjusted to bend Along the nose line To help the mask attach to the wearer's face
2. Filter gas vapor mask Serves to filter suspended gases and vapors in the air
The main component of the gas and vapor filter mask is
The mask and head strap Just as mentioned above The air filter is a cartridge or canned chemical container. Which is the capture of pollutants by absorbing Or react with pollution The air that passes through the filter cartridge is clean and pollution free. This air filter can be used only for each type of gas or vapors specified, such as air filters used to filter ammonia. Will be able to protect only ammonia gas Can not prevent other types of pollution, etc. Therefore, people who will use gas and vapors filter should choose to buy and or choose the appropriate With the type of pollution that will be protected as American National Standard has set the standard (ANSI K 13.1-1973)
Particle Filter Standard N95, USA Used together with the 6000, 7000 air filter cartridge, combined with 501 cover to prevent dust, metal vapor, model 6100/6200/6800/7501/7502. That can be used
Made from synthetic rubber material that does not smell annoying and does not slip while sweating a lot. Lightweight plastic filter cartridge that does not rust even when exposed to concentrated chemicals designed to be horizontal. Not obscuring the eyes while working The filter is easy and convenient. By using a lock Adjustable head strap For comfortable wearing Large hard coated lenses Making it visible.
Dust and chemical protection The face-to-face contact is made of fine silicone. Good material is a dust-proof mask and chemical filter replacement that is easy to use Double pipe mask Ventilated than general masks Can change the filter cartridge immediately one at a time while in use Passed the standards of leading industrial countries such as Australia, South Korea, Japan, America, Europe
Used to filter harmful substances in the atmosphere, moisturize the vapors of organic substances Add particle filters With filtering efficiency in the top grade S1, size 55 cc
3M 6001 Organic Vapor, anti-vapor, solvents, solvents such as lacquers, thinner, toluene, insecticides, steam, used for the protection of hazardous substances in the atmosphere, vapors of organic matter Which effectively meets the requirements of the National Institute for Occupational Safety and Health (NIOSH) and Mine Safety and Health Administration (MSHA), USA
3M 6002 Acid Gas prevents chlorine gas, hydrochloric acid (Hydrochloric acid), sulfuric acid (sulfuric acid), sulfur dioxide, chlorine gas, hydrogen sulfide gas (hydrogen sulfide), used only for escape), passed the standards of leading industrial countries such as America, Europe, Japan
3M 6004 Ammonia / Methylamine Preventing ammonia and vapor methylamine Passed the standards of leading industrial countries such as America, Europe, Japan
3M 7502 Half Facepiece Respirator Medium Advance silicone material for increased comfort and greater durability Proprietary 3M CoolFlow valve helps makes breathing easier Dual-mode head harness adjusts easily for either standard or drop-down mode Exhalation valve cover directs exhaled breath and moisture downward to reduce fogging
