Description
The SR 574 welding shield is intended for use together with the battery-powered SR 500 or SR 700 fan-assisted respiratory protection device systems. The breathing hose of the face shield is to be connected to the fan, and equipped with filters.
The overpressure in the face shield prevents particles and other pollutants from being admitted into the breathing zone.
The products can also be used with compressed air attachment SR 507. This combination forms a breathing apparatus designed for continuous air flow, for connection to a compressed air supply. See separate product leaflet SR 507.
The combinations protect against harmful gases/particles, radiation, and spatter during welding, flame-cutting, grinding, and similar work. The design makes them useful for work in confined and inaccessible areas.
The equipment can be used as an alternative to filtering respirators in all situations for which filter respirators are recommended. This applies particularly to work that is hard, warm, or of long duration.
Before use, a welding lens with appropriate density must be mounted in the welding shield. The SR 574 is delivered with automatic welding lens EN 4/9-13 and protective lens in polycarbonate.
