Removes particles to 3 micron levels
Cellulose depth filtration captures particles far smaller than conventional filters — protecting your equipment from wear and extending oil life dramatically.
Absorbs water and moisture as a multipass
Unlike standard filtration, By Pass systems remove both particulate contamination and water simultaneously — keeping your oil dry and your machinery protected.
Works continuously alongside your existing system
By Pass filtration runs in parallel with your existing system — no downtime, no disruption. Just continuous, silent protection for your oil and your equipment.
