Liquid-liquid separation

Coalescing separator filter

Built around two different elements — a coalescer and a separator — to take free water out of oil without changing the oil itself.

This is the unit that dries oil rather than filtering it. If the problem is water and air in the oil, the answer is a coalescing separator or a purification unit; if the problem is solids in the pipe, it is a strainer.

What it does

How this housing works

  • Stage 1: oil enters the first tray, passes the coalescer element inside-out; solids are held, droplets grow and settle into the sump
  • Stage 2: oil enters the separator element from outside in, collects in the second tray and leaves at the outlet
  • The separator element is oleophilic and hydrophobic: oil passes, free water is held outside and drops to the sump
  • Water leaves through the drain valve at the bottom; the oil leaves dry
