Protect your lungs & face. Breathe Easier. Work Safer.

The combination of the Hot Shield® HS-4 Fire Resistant Mask Housing and the Sundstrom® SR-100 equals easier breathing and greater comfort, even when used for prolonged periods. This special combo allows “fit testing” of individuals because it does not not interfere with fit, form or function.


Hot Shield® Fire Resistant Respirator Housing's patented design provides a high degree of thermal protection to face & neck areas, and to the respirator, using CarbonX, a highly thermally resistant fabric.


 Sundstrom® SR100 APR Half Mask provides the user with the lowest breathing resistance of any half mask available. The ST510 HEPA filter is for protection against soot, ash, and particulates. The SR232 canister protects against multi-gas/vapors. SR-100 canisters are tested to NIOSH standards.


Who could use this combo? 

Wildland firefighters, metal foundry workers, or anyone who needs protection from the hazards of radiant hear, direct flame, embers, particulates, smoke, and vapors.
