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.
1.1 System description
Fig. 1
The SR99-1 compressed air filter mainly consists of a filter regulator
with automatic drain (3), drain bowl (5) and filters (13, 14). Coarser
particles (oil, water, dirt) are removed by centrifugal separation in
the pre-collector. After the pre-collector, the air flows through the
filter, in which even very small particles, as well as gases, vapours
and odours, are removed. The filter is a replaceable filter element
consisting of a central activated carbon filter section (14), sur-
rounded by two particle filters (13).
1.2 Applications
The compressed air filter SR99-1 is used for converting ordinary
compressed air into clean, breathable air. It is also suitable whenever
clean air is needed for pneumatic instruments and tools.
1.3 Warnings
• The filter in SR99-1 must always be depressurized before the
filter element is changed or other work is done on the filter.
1.4 Breathable air
Breathable air shall meet at least the following purity requirements
according to EN12021:2014:
• 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/m
3
.
• the air shall have a sufficiently low dew point to ensure that no
internal freezing will take place in the equipment.
For further particulars of breathable air, see European Standard
EN132:1998 and any other national regulations that may be in
force.

3. Use. Fig. 1
When the filter is used to its maximum capacity, i.e 3 connected
users the available compressor capacity must be at least 900 l/
min. The consumption of any tools connected to this system must
be added to the above values.
The compressor air intake must be located so that there will be no
risk of polluted air being drawn into the system.
• The filter has two outlets (11), one of which is plugged prior to
delivery. Fit the safety coupling supplied (13).
• The inlet thread (2) of the filter is 1 /2” BSP female. Fit a suitable
coupling/nipple.
• The filter is automatically drained to the given level. The drain
can also be opened manually by turning the pre-collector at the
bottom of the drain bowl. Fig 2.
• The filter element is fitted prior to delivery. Note the date on the
label at the outside of the filter housing to be enable you to keep
track of the date when the filter should be changed.
• The SR99-1 is equipped with keyhole mountings for mounting
it on a wall, but it can also be stood on a suitable surface.
4. Maintenance
The person who is responsible for cleaning and maintenance
of the equipment must have suitable training and be well acquainted
with work of this type.
4.1. Cleaning
Clean the outside of the filter as necessary, using soapy water
and a sponge or brush. The filter can also be blown clean with the
compressed air or flushed with water. A good time to clean the filter
regulator and the drain bowl is when the filter insert is replaced.
• Shut of the air inlet.
• Turn the pre-collector at the bottom of the drain bowl to depres-
surise the filter. Fig 2.
• Remove the drain bowl. Press it downward and twist anti-clock-
wise (bayonet mounting). Fig 8. Wash the bowl in hot water (not
