Traditional fixed-speed compressors run at a constant speed, regardless of the actual air demand. This means they often consume more energy than necessary, especially when the demand is low. VSD technology, on the other hand, allows the compressor to adjust its speed according to the air demand.
[pdf] Displacement (m³/min): It refers to the volume of air discharged by the compressor per unit of time, also known as flow rate or volumetric flow rate. Discharge pressure (MPa): It indicates the pressure of the air at the compressor’s outlet, usually measured in megapascals (MPa).
[pdf] If the capacity of the air compressor is really too low, check the following: Check differential pressure over oil separator. Replace separator when necessary. Check and replace compressed air filters (if installed). Compressor does not unload. Check if pressure switch is correctly set and working.
