Wear debris on the way back

Return-line filter

Mounted in the return line where system pressure stays at 1.6 MPa or below, holding back the metal powder and seal rubber that components shed, so the oil going back into the tank stays clean.

Drawing, sample or measurement accepted. Samples are confirmed before mass production.

A return filter is sized on the return flow, not the pump flow. The differential pressure switch is what turns it from a filter into an instrument: you change the element on the signal instead of on a schedule.

What it does

How this housing works

  • Fitted with a differential pressure switch
  • Switch signals when the pressure drop across the element reaches 0.35 MPa
  • Element is then washed or replaced before bypass pressure is reached
  • Protects the tank charge, the next start-up and the pump

Where it runs

Typical duties

  • Hydraulic power units
  • Machine tool and press circuits
  • Gearbox and lubrication return lines
  • Test stands
