2.4. Which air consumption should be taken account of for the MQL?

The devices which spray the medium from outside by spray air (for e.g. Lubrimat / Sawfix / /Spraymat ) need approx 50 NI/min per nozzle at 6 bar under normal conditions with the external lubrication. With the internal lubrication (Toolmat / Centermat), the consumption amounts to approx. 20 – 150 NL/min per tool based on the size of the cooling duct. The “airless systems” Pulsomat do not have any relevant compressed air use.
