Des-Case Hydraulic Off-Line Filtration Units
Brands
Des-CaseThe hydraulic market accepts that 80% of mechanical failures are caused by oil contamination in the system. The Off-Line Filtration System (OLU) attacks contamination of your equipment at the source. In addition to solid particles, this kidney loop system is also capable of removing water from the oil. For critical applications that need regular filtration, or a maintenance location that is hard to access, permanently-mounted OLU improve equipment reliability with continuous-duty, always-on filtration that cleans oil and keeps it clean. A properly sized OLU can turn over the entire volume of a reservoir several times a day (we recommend 5-7 turns), maintaining ISO fluid cleanliness codes well below the upper limit
