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. The characteristics of the SR 540 face shield are as follows: Protects the breathing zone and the crown of the head • Hinged visor unit • Scratch resistant and chemicals resistant PC visor • The supply air flow keeps the visor demisted • Adjustable head harness • Replaceable breathing air hose • Equipped with an exhalation valve • Optional PETG visor, peel-offs and head-cover • Available in one size. The SR 540 is also available in an explosion-protected version designated the SR 540 EX for use in a potentially explosive atmosphere (ATEX Directive 94/9/EC). See the separate product leaflet.
