Description
The SR 900 half mask is an Air Purifying Respirator (APR) made of thermoplastic elastomer (TPE) and polypropylene (PP) in three sizes, i.e. S, M and L. The mask is equipped with two exhalation valves, which ensures very low exhalation resistance. The valve covers with partitions effectively protect the exhalation membrane against dust and paint mist. The material and pigment of the mask body are approved by FDA and BGA for foods, which minimizes the risk of contact allergies. The easily adjustable elastic head harness straps of the mask are designed as a V-shaped loop and have a large dished crown plate, which contributes towards a comfortable and safe fit. The mask is used as an APR in combination with filters and/or cartridges from the Sundström range. A pre-filter holder for simple checking of the performance are supplied. Best stored in box SR 230 or storage case SR 339.
