1. Introduction
The SR 200 Full face mask can be used in three different
configurations:
• Together with filters from the Sundström filter range.
• Together with fan unit SR 500 or SR 500 EX.
• Together with compressed air attachment SR 307
which then serves as a breathing apparatus with
continuous flow for connection to a compressed air
supply.
In addition, the SR 200 is available in a special version - the
SR 200 Airline - that is designed for connection to com-
pressed air, but is also provided with filter back-up.
The Sundström SR 200 Full-face masks provide respira-
tory and eye protection against airborne pollutants, such
as particles, micro-organisms, biochemical substances,
gases/vapours and combinations of these substances
to a user.
The respirator consists of an outer mask with polycar-
bonate or laminated glass visor that covers the user's face,
an integrated inner mask with inhalation and exhalation
valves that covers the user's nose, mouth and chin, a head
harness with 6 mounting points that hold the respirator
in place, and a filter adapter for connecting standard
Sundström filters. The inhaled air flows through a filter
and inhalation membrane into the inner mask. Part of the
air flows past the inside of the visor in order to prevent
misting. The exhaled air is discharged from the face piece
through two exhalation valves. A wide range of accessories
are available. See section 6, List of parts.
