By-pass filters



  • Longer oil change intervals
  • Reduction of operating costs
  • Higher operational reliability
  • Reduced abrasion
  • Reduction of the water content in the oil

By using a bypass filter, particles up to one micrometer and water are filtered out of the system during operation. The chemical aging process of the oil is slowed down, which increases the lifetime of the oil and noticeably extends the replacement intervals. The filters are suitable for filtration of all hydraulic-, gear-, engine-, processing- and other oils, as well as diesel fuel.
