Hi,I attended a presentation yesterday regarding various varnish removal systems. Our paper machine oil systems,(PM220) have what I would call a great amount of varnish build up and would like to post here and see what is regarded the best for removing varnish. Has anyone had any luck with electrostatic removal systems or have you found the CC Jensen type celluose filters work better? I believe this could apply to hydraulic systems,(with a kidney loop). The PM220 oil has vacuum dehydrators attached. Any suggestions? Thanks Much, Brett
