1. General information
The Sundström SR 200 Airline is a breathing apparatus that is supp-
lied with a continuous flow of air and is designed for connection to
a compressed air supply in accordance with EN 14594:2005. The
unique feature of the SR 200 Airline is the scope it provides for filter
back up. If you have any questions regarding the selection and main-
tenance of equipment, consult your work supervisor or get in touch
with the sales outlet. You can also contact the Sundström Safety
AB's Technical Support department.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 pro-
gram but does not replace national or local regulations.
1.1 Applications
The SR 200 Airline can be used as an alternative to filtering devices
in all situations in which the latter are recommended. This applies
especially if the user is doing hard or sustained work, and if the
pollutants have poor warning properties or are particularly toxic.
1.2 System description
The SR 200 Airline is designed for connection to a suitable source of
breathable compressed air. The pressure in the facepiece prevents
polluted ambient air from entering the facepiece.
• A Sundström compressed air supply hose is connected to a
control valve, which is threaded onto the user's belt. The control
valve can be used for adjusting the airflow rate to the facepiece.
• The control valve is equipped with a warning whistle, which will
come into operation if the airflow rate should drop below the
recommended value.
• From the control valve, the air flows through a breathing hose
with check valve and into the facepiece. The connection in the
facepiece is provided with an air distributor that also serves as a
silencer.
In order to prevent the admission of polluted air, the filter mounting
must be blanked off either with the sealing plug supplied or with a
suitable filter. One of the following methods can be used:
1. Seal the filter mounting by means of the sealing plug supplied.
The equipment can then be used as conventional compressed
air equipment. Fig. 1:a.
2. Connect the filter adapter to the filter mounting and fit a suitable
filter. See 2.4.1. The equipment can then be used as a filtering
device when no compressed air is supplied, e.g. when the user is
in the course of moving to or from the work area, or in the event
of inadvertent interruption in the air supply. Fig. 1:b.
3. The back-up filter can be blanked off with the sealing cover in order
to extend the useful life of the filter. The sealing cover must then
obviously be removed when the system is in use in order to allow
breathable air to be admitted through the filter, if necessary. Fig. 1:c.
1.3 Breathable air
Breathable air shall meet at least the following purity requirements:
• the pollutants shall be maintained at a minimum and must never
exceed the hygienic limit value.
• the content of mineral oil in the air must be so low that the air will
have no oil smell (the threshold of smell is around 0.3 mg/m

• the air shall have a sufficiently low dew point to avoid internal
In the event of uncertainty as to whether the above demands have
been met, a filter such as the Sundström type SR 99 compressed air
filter should be connected. Fig. 25. The SR 99 compressed air filter
consists of a pre-collector and a main filter.
The main filter consists of a gas filter section (class A3 as per EN
141:1990 and AS/NZS 1716:2012) with about 500 g of activated
carbon, surrounded by two particle filters ( class P3 as per EN 143:1990
and AS/NZS 1716:2012). The collecting capacity is 100 - 150 g of oil.
The SR 99H is an air heater that can be connected after the compres-
sed air filter SR 99. Fig 26. For further particulars of breathable air,
see European Standard EN 132:1998, Australian Standard AS/NZS
1715:2009 and any other national regulations that may be in force.

o Connect the breathing hose of the facepiece to the control
valve. Fig. 3
o Connect the compressed air supply hose to the control valve.
Fig. 4.
o Turn the control valve knob anti-clockwise as far as it will
go, in order to throttle the airflow rate to a minimum. Fig. 3.
o Place the facepiece in the bag and grip the opening of the
bag so that it seals around the breathing hose. Fig. 2.
o Grip the flow meter with the other hand and hold it so that
it points vertically up from the bag.
o Read the position of the ball in the tube. It should float level
