KLASSEN SPECIALTY HYDRAULICS INC. - Canadian distributor for C.C.Jensen since 1994

The C.C.Jensen VRU is specially suited to not just mitigation and prevention of varnish related issues, but true removal of varnish from the oil as well as the internal surfaces of the oil system.

By working with the inherent nature of varnish, the specially formulated VRi varnish removal filter inserts become the perfect resting place for varnish to precipitate and collect, instead of the typical trouble areas in your turbine or oil system such as tanks, coolers, and servo valves.

Every VRU is sold with our “No Cure, No Pay” promise to give you complete confidence and ensure your lasting satisfaction.

Never wonder: where did the varnish go?

Filtration Rating: 3µm absolute
