The Vision 3 face masks are designed to be used with the 3M Scott range of breathing apparatus, from the Professional Fire Fighting SCBA to the Airline and escape breathing apparatus range. The multicurvature face mask visor provides excellent panoramic vision and is made of a scratch- and impact-resistant polycarbonate material with a scratch resistant coating. The face mask allows the user to wear integrated spectacle frames without compromising the face mask seal. The face mask features a left-hand side bayonet connection for the demand valve. A speech diaphragm is mounted at the front of the mask to offer unimpeded speech transmission and includes a low-resistance positive-pressure exhalation valve to allow for normal breathing when used in positive pressure mode.
