Sundström SR900 modular half-face respirator

Click2Contact

The Sundström SR900 is a breathing protection system which offers wide-ranging connection possibilities.

The half-mask respirator is not only made of Thermo-Plastic Elastomer and can be fitted with any Sundström gas or particle filter or filter combination, but when the filter attachment is removed a number of extra connection possibilities are available. Users can twist apart the mask body at the bayonet fitting, which allows the respirator to be connected to other devices, such as Sundström’s PAPR fan units and compressed air supply. This is done through a single or double breathing hose fitted to the mask.

The mask takes on a very shallow profile, making it suitable for welding, since it can fit inside a welding shield or visor. An additional benefit is that the filter is mounted well away from welding hazards, such as sparks, heat and metal fumes.

The SR905 remote filter holder is also available for the respirator, which can also be used with single or twin breathing hoses. The filter sits on a belt and can be moved to any position around the waist. Flame-resistant non-spark protective sleeves are also available for the hose, as well as a spark-catching mesh mounted inside the filter holder.
