Free air delivery, usually quoted in CFM or cubic metres per minute, tells you how much air a compressor actually produces. Comparing machines correctly requires a consistent reference point.
Understand Rated Conditions
Manufacturers rate output at specific inlet conditions. Ambient temperature and altitude change real output, so check the reference basis before comparing models.
Convert Between Units
One cubic metre per minute equals about thirty five cubic feet per minute. Convert all equipment requirements to the same unit before adding demand.
Add a Safety Margin
Include leakage and peak events so the compressor never runs flat out at the edge of its rating.
Our engineers can build a demand table and convert it to a firm machine selection.
