To reward the lubrication and reliability community for their participation in the Noria Message Boards, we've started the Post of the Week award. Every week, we award one lucky member $50 (USD).

To nominate a member for the Post of the Week award, send an e-mail to info@noria.com mentioning the name of the member, the topic name and the date and time of the post. Award period is based on the calendar week (Sunday - Saturday) and is awarded on the following Wednesday.

Posts selected for the Post of the Week award rarely stand alone. They are usually a part of an ongoing discussion, and are out of context when presented here. The post should be read in that light.

Forum: Filtration and Contamination Control
Topic: Filter carts vs. 220 vis?

80 ppm of Fe isn't overly bad....but in keeping with your questin we are using a Zinga cart that works well with an ISO 220 at ~ 90F. On a good week we can get down to a 15/13. On a bad week with the same system we are running at a 22/18 (lots of contamination ingress.)

However whenever you are looking at specifying a fltration system for a specific application it is better to know exactly what you are trying to remove. For instance if the reason you are getting such a high PC is because of water in the oil then a standard filter with a high Beta rating won't do anything for you.

If the issue is air bubbles in the oil then filtration will not improve the situation. You can get a 120 filter cart for an ISO 220 at low temperatures, just about anywhere but getting one to suit your application is what you need. I might suggest you consider 1> working with a filtration cart company to analyse and identify your application and contaminent or 2> get your lab to investigate the cause of the high particle count and then proceed to put together a specification to send to several portable filter cart vendors for quote.
