Oil/Water Calculator

A guide to help you size your compressor installation with the correct SEPURA™ oil-water separator.

The total free air displacement capacity of the compressor system in cfm, m3/h or ls.

This is a required field

Average Ambient Temperature in °C.

Please enter a value between -70°C and 70°C

The pressure dew-point of the compressed air when a refrigerant air dryer is installed in the system is usually around 3°C. If no refrigerant dryer is installed then this figure should be around 5°C higher than the ambient temperature figure.

Please enter a value between -70°C and 70°C

Enter the average relative Humidity in %.

This is a required field

If you know the ppm/oil water then choose the 'Oil Loading Factor' that reflects this figure. (you will have to press Calculate) Otherwise this figure is subjective. For Example insert a number '2' for a very new and lightly used compressor and up to 6 for a very well used compressor.

This is a required field

Working air pressure of the compressed-air system in bar (g).
