Description

Comparisions

	Screw Air Compressor	Piston Air Compressor
30~40bar Air Compressor	Oil free Screw Air Compressor	Oil free Piston Air Compressor
Air quality	Oil free (TUV Class 0 Certificate)	Air cylinder Oil free, Crankcase has oil
Compression Method	2 Stage Screw	3 Stage Piston
Lubricating Medium	Pure Water	None
Temperature	Low: < 55℃, No need for cooling	High: 125~200℃, After cooling about 60℃
Cooling Method	Air Cooled or Water Cooled (Only one cooler for lubricating water)	Water Cooled (Two interstage cooler and one after cooler for compressed air)
Rotate Speed	3000 r/min Ideal Speed	600~900 r/min Low Speed
Vibration and Noise	Balance and Simple structure, low vibration and less noise	The pistons rise and fall or move back and forth causing too much vibration and Noise

Costs – Purchasing	More	Less
Costs – Foundation	No costs	Require foundation and grouting due to high unbalanced forces & high vibration.
Costs – Maintenance	Only Air filter elements and Water filter elements	High wear & tear of moving parts like piston rings, valves, etc.
Costs – Energy	Motor Power: 112kW (1st stage 75kW+2nd stage 37kW) (e.g. 40bar 10m3/min)	Motor Power: 132kW (e.g. 40bar 10m3/min)
Capacity Loss	There is no loss / very minor loss in Capacity over a period.	There is De-ration in Capacity due to wear and tear in-cylinder crankcase, piston rings, pistons, and valves.
