1. General information
The Sundström SR 507 compressed air attachment can be used
together with Sundström human interfaces (hoods SR 520/SR 530/
SR 561/SR 562, face shield SR 540/SR 570/SR 540 EX, helmet
with visor SR 580, welding shield/helmet with visor SR 584/SR 580,
welding shield SR 590 and half mask SR 900/SR 951) below
named head-tops. This combination forms a breathing apparatus
with continuous airflow for connection to a compressed air supply.
If you feel uncertain about the selection and care of the equip-
ment, 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.
1.1 Applications
The SR 507 is an attachment that enables a given head-top to be
converted between a fan-assisted respiratory protective device and
a protective device with compressed air supply.
The compressed air attachment can be used as an alternative to a
filtering device in all situations in which the latter is recommended.
This applies particularly if the user is doing hard or sustained work
and if the pollutants have poor warning properties or are particularly
toxic. The SR 507 is made of materials that are not liable to give rise
to sparking when subjected to friction, which enables the attach-
ment to be used in an explosive or fire-hazardous environment.
1.2 System description
The SR 507 is designed for connection to a suitable source of
breathable compressed air. The pressure in the head top prevents
polluted ambient air from entering the head top. A compressed air
supply hose, which must be approved for breathable air, is con-
nected to a control valve that is threaded onto the user’s belt. The
control valve can be used for adjusting the airflow rate to the head
top. From the control valve, the air flows through the connecting
adapter to a breathing hose, and then into the head top.
The control valve is equipped with a warning whistle, which will
come into operation if the airflow rate should drop below the recom-
mended value.
1.3 Breathable air
Breathable air shall meet at least the following purity requirements
according to EN 12021:1998:
• The pollutants must be maintained at a minimum and must never
exceed the hygienic limit value.
• The content of mineral oil shall be so low that the air will have no
oil smell (the threshold of smell is around 0.3 mg/m³).
• The air shall have a sufficiently low dew point to ensure that no
internal freezing will take place in the equipment.
In the event of uncertainty as to whether the above demands have
been met, a filter such as the Sundström type SR 99-1 compressed
air filter should be connected. Fig. 7.The SR 99-1 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 activa-
ted 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. 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.
