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 of the mask is designed as a V-shaped loop and has a large, dished crown plate, which contributes towards a comfortable and secure fit.

The Compressed air attachment SR 307 can be connected. A pre-filter holder and test disc for simple checking of the performance are supplied. Best stored in box SR 230 or storage case SR 339.
