Reply to "Hydraulic oil filtration"

The best way for filtration of hydraulic oils is microfiltration! But you have to use a real microfiltering system. EUROPAFILTER takes particles down to 0,1 micron and all kinds of water. It's made of woodpulp and take both particles and water in the same operation.
98 % of the particles are below 5 micron and will not be counted when using ISO4406 or NAS1638. Mostly of the filters on the market don't take particles below 3 micron. But even that, no one comes down to ISO4406 class 14/7 or so. EUROPAFILTER goes down to ISO4406 class 8/6 and water to under 50 ppm.
