Oil free Screw Air Compressor

Oil free Piston 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.
