Msa Safety 464046 Respirator Cartridge Acid Gas Organic Vapor

Product Description

The MSA SAFETY 464046 is a replacement respirator cartridge designed for use with the Ultra Twin series powered air-purifying respirator (PAPR) and half/full-face respirator systems. It provides combined protection against acid gases and organic vapors, with N95 and R95 filter ratings that meet NIOSH approval standards. Identified by its yellow color code for quick visual identification in the field, this cartridge is the correct service part when replacing spent filtration media in the Ultra Twin platform. Installation is performed by qualified safety professionals, industrial hygienists, or trained workers operating in environments with airborne chemical hazards.

This cartridge is suited for industrial and occupational environments where workers may be exposed to acid gas vapors or organic vapor concentrations within NIOSH-approved service limits. Typical applications include chemical processing, painting and coating operations, petrochemical facilities, and similar settings requiring NIOSH-rated respiratory protection. The Ultra Twin product line compatibility makes it a direct-fit service replacement for existing Ultra Twin respirator assemblies already in use on a job site or in a facility program.
