The SR 100 half mask Air Purifying Respirator is made of silicone and is available in two sizes, S/M and M/L.

The mask is equipped with two exhalation valves, which ensures very low exhalation resistance.  Valve covers with baffles effectively protect the exhalation membrane against dust and paint mist.


The easily adjustable elastic head harness is designed as a V-shaped loop and has a large, dished crown plate, which contributes to a comfortable and secure fit.


The compressed air attachment SR 307 can be connected to the SR 100 half mask, this combination is called a Type C Continuous Flow Supplied Air Respirator.
