The Type 80 gas mask filter is a robust durable canister intended for military and civil defense utilize. Information technology is especially designed for condolement and extended utilize at a minimal physiological load, having low animate resistance and low weight. Its blueprint assures optimal performance complying with all IDF specifications as well as the performance requirements of the American Army C2 filter canister.

These filters are designed as a twin filter system that sits close to the face, providing high protection and very low breathing resistance which suits in that location armed services utilise in demanding physical environments. They protect confronting chemical, biological, radiological, and nuclear (CBRN) threats (including toxic industrial materials).

More specifically, they are suitable confronting:
Arsine, Asbestos, Bacteria, Benzene, Blister Agent, Blood Agent, Bromine, Carbon Dioxide, Carbon Monoxide
Carbon Tetrachloride, Chlorine, Chlorine Dioxide, Chloroacetophenone (CN),Chloropicrin, o-Chlorobenzylidene Malononitrile (CS), Cyanogen, Cyanogen Chloride (CK), Cyclohexane, Fluorine, Formaldehyde, Hydrogen Chloride, Hydrogen Cyanide (AC)
Hydrogen Sulfide, Lewisite, Mustard (Hard disk), Nerve Amanuensis, Nitrogen Dioxide, Nuisance Dusts, Nuisance Odors, Oleoresin Capsicum (OC, Pepper Gas), Organic Vapors due west/ Boiling Indicate >65 Degree C, Particulates, Phosgene, Phosphine,Radioactive Particulates, Sarin (GB), Soman (GD) Sulfur Dioxide, Tabun (GA), Toluene, Virus, VX, Xylene.

The M61 filters have a predicted shelf-life of 5 years (when sealed and packaged).

How To Choose A Gas Mask Filter

What is the purpose of the gas mask filter?

A war machine-course filter (NBC/CBRN) will work in two means. Offset, it does a simple particle filter, much similar a water filter would, and removes the bacteria in the inhaled oxygen. This is essentially a physical barrier, interim similar a textile being held over your mouth to stop smoke inhalation, only this ane covers much effectively particles. The next process is adsorption and is a chemical process, unlike the first i, to remove toxic gases and molecules. This is where gas masks differ to things such as respirators, dust masks, or using a wet textile over the rima oris while escaping a called-for building.
