Description:

Battery-powered, fan-assisted air-purifying 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.

The fan can be used with Sundström hoods, face shields or full face masks. The fan unit is fitted with a suitable filter, and the filtered air is fed through a hose to the facepiece.

IMPORTANT:

The Sundström SR500 is a PAPR (Powered Air Purifying Respirator)

It is a positive-pressure respirator at work requiring less than 225 l/min peak air flows

At higher work rates, the SR500 may provide extra comfort, but NOT positive-pressure protection, and will therefore rely on face seal (provided you have a tight-fitting face piece)
