Organic Vapor/Acid Gas Cartridges *Old Series* (Pair)

*These cartridges fit the old series (navy blue) masks that are no longer available. If you are purchasing or own a new series (black) mask, you must purchase Item C-139-19.

Approved vapor protection against 50 ppm hydrogen chloride, 50 ppm sulfur dioxide, 10 ppm chlorine, and 1000 ppm organic vapors having good warning properties. Hydrogen Chloride is one of the fumes emitted from salt kilns. However, because of the variable emissions from a salt kiln, the appropriateness of using this mask during the salt firing process must be carefully considered. This cartridge is also useful for application and firing of metallic lusters. Sold in Pairs only: one Pair required per mask.

NOTE: This cartridge does not provide any protection against dust on its own. A Dust/Mist Pre-Filter can be added if dust protection is also required. See Item No C-139-13K.
