Electrostatic charging in hydraulic control and turbine lube oil systems can result in high voltage discharge or ‘sparking,’ causing fluid breakdown and varnish formation.

How do I know if I have electro-static discharge (ESD) in my fluid system? 

• Can you hear a sharp, crackling noise coming from the filter housing or other downstream components such as heat exchangers or the reservoir? If you do, that’s ESD! 
• When you replace your filter elements are there burn marks or holes on the outer filter media?  That’s ESD! 
• When maintaining system components, do you notice scorch marks of the metallic surfaces or that they have a dark, sticky coating, or ‘varnish’ as it is referred to? That’s the effect of oil degradation potentially caused by ESD!
• Or do you need to replace your fluid more often than you would expect?  ESD can be a cause of fluid degradation, reducing the service life of the oil, depleting the additives and generating fine carbonaceous and resinous, varnish forming material. 

We’ve designed the Pall Athalon filter to significantly reduce the level of electrostatic charging and while consistently maintaining superior fluid cleanliness for the full service life of the filter.

Better, more consistent system protection, cleaner, varnish free fluid systems, improved equipment performance and reliability.
