Dirt and Particles

Dirt and wear particles in your oil act like sandpaper inside your equipment — grinding away at pumps, valves, and bearings. Leading to increased wear, higher maintenance costs, and unexpected downtime. With proper filtration, you can drastically reduce these risks and extend both oil and equipment life.

Water

Even small amounts of water can cause rust, reduce lubrication, and accelerate oil degradation. This leads to premature failure of bearings, gears, and other critical components. With effective offline filtration, you can remove free, emulsified, and dissolved water — protecting your equipment and maximizing reliability.

Varnish

Varnish forms as oil degrades, leaving sticky residues that clog valves, reduce efficiency, and cause failures. It leads to sluggish operation, overheating, and costly downtime. Advanced filtration removes varnish and its precursors, keeping your oil systems clean and reliable.
