Sundström Respirators are Leaders in Comfort & Performance

SR 900 half mask Air Purifying Respirator

The SR 905 is a remote filter holder that, combined with the half mask SR900 and breathing hose SR951 or SR 952, offers a low-profile mask with greater freedom of movement. The remote filter holder moves the weight and bulk of the filters away from the face to the waist and is compatible with all Sundstrom APR filters and cartridges. The low-profile mask system fits easily under most welding and grinding shields allowing a wider range of applications. The SR 905  is intended to be used in the same environments as the half-mask respirator. 

About the SR 900 Half Mask

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 APR mask is used in combination with:
• Filters and/or cartridges from the Sundström range.
• Remote filter holder SR 905 according to 42 CFR part 84.
• Powered Air-Purifying Respirator (PAPR) SR 500 and approved filters/cartridges included in the Sundström PAPR range according to 42 CFR part 84. A pre-filter holder for simple checking of the performance is supplied. Best stored in box SR 230 or storage case SR 339."

Common Respirator Applications 

When choosing the right respiratory protection system, it is important to know precisely what work the user will be undertaking and the risks involved. Environmental factors must also be considered and whether there are specific regulations that have to be followed. Below are some common uses for a full-face respirator, however it's important to know your hazard type and concentration levels of the hazardous particulate, chemical, gas or vapour. If the atmosphere is immediately hazardous or dangerous to life or health you must not use a full face mask with filters. Supplied air or a self-contained breathing apparatus is required. Full face masks should only be used with hazards that do not exceed an assigned protection factor of 50.
