1. General information
The Sundström SR 90 Airline is a breathing apparatus which
is supplied with a continuous flow of air and is designed for
connection to a compressed air supply in accordance with
European Standard EN 14594: 2005 and AS/NZS 1716:2003.
The unique feature of the SR 90 Airline is the scope it provides
for filter back-up.
The SR 90 Airline is available with the facepiece made of two differ-
ent materials, i.e. silicone or TPE, and in two sizes, i.e. M/L or S/M.
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 1715:1994.
The guidance contained in these standards highlights important
aspects of a respiratory protective device program but does not
replace national or local regulations.
1.1 Applications
The SR 90 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 90 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 compressed air supply hose which is approved for breathable
air is connected to a control valve threaded onto the user's belt.
The control valve can be used for adjusting the air flow rate to the
facepiece. The control valve is equipped with a warning whistle
which will come into operation if the air flow 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 which also serves as
a silencer. When the facepiece is in use, the filter mounting must
be blanked off in order to prevent the admission of polluted air.

One of the following methods can be used for blanking off the
filter mounting:
1. Seal the filter mounting by means of the sealing cover supplied.
2. Fit a suitable filter to the filter mounting. The equipment can
3. The back-up filter can be blanked off with the sealing cover
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
• the content of mineral oil in the air must be so low that the air
• 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 49/SR 79
compressed air filter should be connected. Fig. 9-11. The SR 79
compressed air filter consists of a pre-collector and a main filter.
The pre-collector is of centrifugal type, and is specially designed
so that it will also be able to arrest surges of water and oil. It is
also equipped with a sintered pre-filter. The SR 79 is also available
with air heater SR 79H. The SR 49 has a standard type of pre-
collector, but is fitted with the same main filter as the SR 79. The
main filter consists of a gas filter section (A3 as per EN 141:1990
and AS/NZS 1716:2003) with about 500 g of activated carbon,
surrounded by two particle filters (P3 as per EN 143:1990 and
AS/NZS 1716:2003). The collecting capacity is 100 - 150 g of oil.
For further particulars of breathable air, see European Standard
EN 132:1998, Australian Standard AS/NZS 1715:2003 and any
other national regulations that may be in force.
2.1 Unpacking
Check that the equipment is complete in accordance with the
packing list and that no transport damage has occurred.
The equipment can then be used as conventional compressed
air equipment, Fig. 1:a
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
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
