Minimum quantity lubrication vs. oil mist systems

MMS doses very small oil volumes precisely – cleanly and efficiently. Oil mist systems Nebulize oil finely and distribute it over a larger area. Which solution is right depends on the process, cleanliness and target values.

Working principle

  • MMS: Oil is delivered in minimal quantities with air (oil-air), directly to the cutting/contact zone.
  • Oil mist: Oil is atomized and led to larger areas via pipes/ducts.

Areas of application

  • MMS: Machine tools, clean environments, precise spots, little rework/cleaning.
  • Oil mist: large/sensitive areas when light film is desired.

Advantages & Disadvantages

  • MMS advantages: very low consumption, clean processes, exact dosage.
  • MMS limits: not ideal for very open/wide areas.
  • Oil mist benefits: even surface wetting, easy distribution.
  • Oil mist limits: more oil in the area, more cleaning effort possible.

Media & sizing

  • Oil selection based on viscosity/temperature and process (H1 optional).
  • Ensure air quality & pressure stability.
  • Sensors/monitoring: flow/pressures at a glance.

Frequently asked questions

Can you retrofit MMS

Yes, if the machine geometry/space is suitable; Check cable routing & air supply.

How much oil does MMS use

Very small quantities – depending on process/interval; Consumption is typically significantly lower than with oil mist.
