The SR 540 face shield together with the battery-powered SR 500 or SR 700 fan and approved filters are included in the
Sundström fan-assisted respiratory protection device systems. The breathing hose of the face shield is to be connected
to the fan, equipped with filters. The pressure generated in the face shield prevents particles and other pollutants from
entering the hood.
The SR 540 can also be used with the SR 507 compressed air equipment. This combination forms a breathing apparatus
designed for continuous air flow, for connection to a compressed air supply.
The equipment can be used as an alternative to filter respirators in all situations for which filter respirators are recommended.
This applies particularly to work that is hard, warm or of long duration.
