Comfo Elite¨ Half-Mask Respirators

The Comfo Elite Respirator provides protection against a variety of respiratory hazards. The respirator uses chemical cartridges or aerosol filters, or a combination of the two, to remove specific contaminants from the inhaled air. The filters/cartridges are interchangeable among most other MSA Twin-Cartridge Respirators.

Chin-Type Gas Masks

The Chin-Type Gas Mask provides face and respiratory protection against particulate matter, vapors and gases by means of a lightweight, replaceable canister. The small, oval-shaped aluminum canister and facepiece are designed to permit downward head movement. This comfortable, lightweight model is often chosen as an alternative to the heavier models. The MSA Chin-Type Gas Mask is designed for respiratory protection against a specific gas or group of gases as indicated by canister identification. The gas mask assembly has the following Maximum Use Conditions: Entry-100% the Permissible Exposure Level-do not exceed the Immediately Dangerous to Life and Health (IDLH) concentration. Escape-contaminant concentrations up to the maximum use concentration of the gas mask (generally 5,000 ppm (0.5%) by volume; see canister selection chart for details), providing there is adequate oxygen (19.5% by volume) to support life. At these upper use conditions, the service time may by extremely short (as low as 12 minutes).

Super-Size & Industrial-Size Gas Masks

The MSA Super-Size and Industrial-Size Gas Masks are designed for respiratory protection against a specific gas or group of gases, as indicated by canister identification. The gas mask assembly has the following Maximum Use Condition: Entry--100x the Permissible Exposure Level--do not exceed the Immediately Dangerous to Life or Health (IDLH) concentration. Escape--contaminant concentrations up to the maximum use concentration of the gas mask (generally, 20,000 ppm (2%) by volume; see canister selection chart for details), providing there is adequate oxygen (19.5 percent by volume) to support life. At these upper use conditions, the service time may be extremely short (as low as 12 minutes). As indicated by its name, the Super-Size Gas Mask has an extra-large canister which will last approximately twice as long as the equivalent Industrial-Size Canister because of a larger volume of chemical fill.
