Sundström SR900 respirator system

Description

A half mask and a system

Use in a variety of ways

SR 900 is a completely new system where the user can easily customise the product based on site requirement and needs. The respirator can be easily configured for filters, PAPR, supplied air, as well as a remote filter holder mounted on the waist belt.

Remote filter holder: ideal for welding

By removing the filter attachment on the mask (simply twist the bayonet fitting) and attaching the breathing hose and remote filter holder, you can wear the filter behind your back.
The filter sits on a waist belt and can be moved to any position.
In turn, the mask itself is given a very shallow profile. This makes it ideal for welding, as it easily fits inside a welding shield or visor.
An additional benefit is that the filter is mounted well away from any welding hazards, such as sparks, heat and metal fumes.
