These elements still get affected by electrostatic problems, any element that isn't stat-free that has a hydraulic load applied to it by fluid (l/min /cm^2) will cause electrostatic charge to be built up.
Instead of what filters you use, you should be asking what are the properties of your...
Here are some graphs that I've taken from a presentation we've done in a seminar to several large companies.
These were measured using a stat stick in a normal non "stat-free" element.
It seems like you're covered then Pkruse, it's up to you what you do with your system and...
It can cause a few problems, obviously depending on the fluid it can be explosive!
Much more common problems are caused by the sparks it gives causing holes in the filter element, which will obviously be larger than the elements micron rating, this allows unwanted contamination of large...
I just typed out a massive post and accidentally pressed the back button and wiped it!
Anyway:
Apologies for the delayed response I'm currently away on a course and unable to get decent internet access.
Electrostatic discharge is a fairly new phenomenon due to oil companies becoming under...
I know this is a general Mechanical Engineering forum, but there is no Hydraulic forum and this is the nearest trade.

I've been doing a project on electrostatic discharge, and the company I work for (I won't mention the name as I'm not here...
