[pdf] Loose screws, bolts, or other components can vibrate and create noise during operation. Tightening these components can often resolve the issue. 2. Worn Bearings Bearings wear out over time, causing friction and noise. Replacing worn bearings can restore quiet operation. 3. Intake Air Filter Clogged
[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).
