When performing an oil flush on your equipment, it is important to have a plan and procedures that take into account the criteria and materials used for deeming the system clean. This includes particles you cannot see with a naked eye. The width of an average human hair is approximately 40 microns, but particles as small as 2 microns can damage your system. How can you judge your system clean if you cannot see the material? There are several options.

  1. Use a laboratory
  2. Patch kits
  3. Portable particle counters
  4. Visual inspections
  5. Wye strainers
  6. Basket strainers
  7. Witch's hat strainers
  8. Bag filters
  9. Flange screens
