Data Sheet: Sundström SR700

Particles-only PAPR

Battery-powered, fan-assisted air-purifying particle filter respirator that can be used as an alternative to negative-pressure filter respirators where these are recommended. This applies particularly to extended periods of hard work in warm conditions. NOTE: This respirator is for PARTICLES ONLY and must not be fitted with gas filters. The fan can be used with Sundström hoods, face shields or full face masks. The fan unit is fitted with two particle filters, and the filtered air is fed through a hose to the facepiece.
