Oil passes slowly through roughly 40 mm of wound cellulose media. The full depth of the bed traps particles down to 3 µm absolute, absorbs free and emulsified water, and holds the soft oxidation products that form varnish. The filter itself applies no heat, no vacuum and has no rotating parts. Where more water has to come out, a CJC Desorber does it by desorption into dry air, not by vacuum.

0.8 µm nominal
Low flow through a deep media bed.
A contaminated tank cleans up in stages. The trend also shows whether the dirt ingress has stopped.
Indicative trend for a hydraulic system of a few thousand litres, six tank turnovers a day. Heavier ingress, colder oil or a bigger tank takes longer.
The lab count measures the change. The samples show it.
Before
Dark and hazy. Water above the alarm limit.
After
Same oil and machine, after offline filtration.

Vacuum dehydration and centrifuges are the common alternatives. Both work within their duty. Both cost more to run, and neither removes the oxidation products that form varnish.
