1. Introduction
The half masks are used either as filtering
devices in combination with filters from the
Sundström range, or in combination with the
SR 307 compressed air attachment which then
serves as a breathing apparatus with continuous
flow for connection to a compressed air supply.
The Sundström half masks provide respiratory
protection against airborne pollutants, such
as particles, micro-organisms, biochemical
substances, gases/vapours and combinations
of these substances to a user.
The respirators consist of a mask body made
of silicone (SR 100) or TPE, Thermo Plastic
Elastomer (SR 90-3), that covers the user's
nose, mouth and chin. It is equipped with
inhalation and exhalation valves, an easily
adjustable elastic head harness designed as
a V-shaped loop that holds the respirator in
place and a filter attachment for connecting
standard Sundström filters.
The inhaled air flows through a filter and inhala-
tion membrane into the mask. 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.

or sideburns which cross the respirator
surface.
• If scars or other physical characteristics may
interfere with a proper fit of the respirator.
• Caution must be taken when using the

If you feel uncertain about the selection and
care of the equipment, consult your work
supervisor or get in touch with the sales outlet.
You are also welcome to get in touch with the
Technical Service Department at Sundström
Safety AB. Use of a respirator must be part of a
respiratory protection program. For advice see
EN 529:2005 or AS/NZS 1715:2009.
The guidance contained in these standards
highlights important aspects of a respiratory
protective device program but does not replace
national or local regulations.
