solvent) at a maximum of 60 °C.
• Remove the pre-collector element by turning it anti-clockwise
(Fig. 9).
• Blow the parts clean with compressed air. Check that the drain
outlet is not obstructed.
• Refit the filter element and the drain bowl.

4.2. Filter change

Under normal operating conditions, the filter element has a useful
life of around six months. However, the useful life may vary widely,
depending on the condition of the compressed air system and the
air flow rate through the filter. The condition of the filter element
can be assessed by weighing. The original weight is shown on the
filter element. If the weight has increased by about 100-150 grams,
the filter should be changed. If the smell or taste of the impurities
become detectable, the filter should immediately be changed:
• Shut off the air inlet.
• Turn the pre-collector at the bottom of the drain bowl to depres-
surise the filter. Fig 2.
• Loosen the hose between the regulator and filter lid by pushing
the red sleeve on the coupling and disconnect the hose from the
lid. Fig 3.
• Unscrew the knobs of the filter housing and remove the lid. Fig 4.
• Remove the used filter element. Fig 5. Clean and wipe if necces-
sary.
• Check the seals and change if they are damaged. Fig 6. Two
seals (A and D) seals towards the filter housing (C). Seal (E) seals
against the clean side of the filter element (B) towards the outlet.
• Mount the new filter element. This has identical ends and can
be fitted either way round. Fig. 6.
Then assemble the filter:
• Refit the cover. Fig. 4.
• Connect the hose between the control valve and filter lid by
pushing the hose into the connector. Fig 3.
• Check that the pads on the cover and end caps fit into their
grooves. Fig. 7.
• Tighten the knobs alternately by hand until the lid meets the filter
housing.
Dispose of used filters in an appropriate manner, observing the
relevant rules and instructions.

5. Technical specification

Particle collecting capacity
The class A3P3 filter element collects more than 99.99% of all
particles at a flow rate of 95 l/min and using paraffin oil as the test
aerosol (EN 143:2000).
Collection of gases/vapours
The class A3P3 filter element can adsorb 100–150 grams of oil
before it is saturated (EN 14387:2004).
Supply pressure
6–10 bar (600–1,000 kPa).
Air flow rate
Max. 900 l/min.
Supply pipe
The supply pipe to the compressed air filter must have an inside
diameter of at least 11 mm to ensure that it can deliver the maxi-
mum air flow rate.
Compressed air supply tube
The following tubes are type approved together with all Sundström
compressed air fed equipment.
• SR 358. 10/16 mm rubber tube, made of polyester reinforced
PVC. Oil and chemicals resistent. 5–30 m.
• SR 359. 9.5/19 mm plastic tube, made of polyester reinforced
EPDM. Antistatic, heat resistant. 5–30 m.
• SR 360. 8/12 mm plastic spiral coiled tube made of Polyurethane.
2, 4, 6 and 8 m.
The tubes should be used separately. It is not allowed to join tubes
together.
