VR Series

You are here:

Varnish is the accumulation of oil oxidation and degradation compounds on machine surfaces or components. It has many possible root causes, including; high temperatures, electrostatic discharge, lubricant degradation and microdieseling.
Initially, varnish is hard to diagnose as it is 100% dissolved in oil. Once varnish reaches a saturation point, impurities begin to accumulate on metal surfaces due to their polar nature.
Over time, varnish can case many issue that reduce system performance including valve stiction, lubricant flow restriction, reduce heat rejection and clogged filters.

The solubility of oil is directly related to oil temperature; warmer oil will hold more polar molecules in solution. Both varnish products and water are polar molecules.
The VR series filter cools oil to below 20C, to shift polar substances from solution to suspension.
The molecules are then passed through 114mm of polar, cellulose media, which attracts the varnish contamination and absorbs the water molecules.
