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.
2.1 Shut off the air inlet.
Turn the pre-collector at the
bottom of the drain bowl to
depressurise the filter.
2.2 Loosen the hose between
the regulator and filter lid by
pushing the red sleeve on the
coupling and disconnect the
hose from the lid.
2.3 Unscrew the knobs of the
filter housing and remove the
lid.
