What is varnish?

Varnish takes the form of insoluble oil ageing products which settle in the tank, in valves or in bearings. These can be non-filterable gels or solid paint type deposits.

With the VMU series, the removal of varnish is on the basis of absorption on an active surface. Therefore, the VMU series answer to an offline utilisation.
