Comparison	Water Lubricated oil-free single screw air compressor	Dry oil-free double screw air compressor
Air Discharge Temp	About 50ºC	About 180-200ºC
Clearance Volume	Rotor has been used twice through one circulation No clearance volume left	Rotor has been used once through one circulation  Existing clearance volume
Air Delivery	Ideal isothemal compression,air delivery volume5%-12% more	Energy lost due to hot air discharge
Efficiency	Normally:59-6.4 kw/(m3/min)	Normally:6.0-6.6 kw(m3/min)
Air Quality	100% oil-free	Oil in the gear,high risk of air quality
Air Purity	Purified by water,clean air after separation	Directly compressed then discharge,containing dust and oil stain
Structure Balance	Radial and axial loads cancel each other	Radial load is not been balanced
Noise and Vibration	Simple structure,Low vibration and less noise,Normally:60-65 dB(A)	High frequency noise due to screw grinding,Normally:64-78 dB(A)
Durability	Rotation speed 3000r/min,theoretically zeao load,long lifetime of screw(30000h),star wheel(50000h)	Rotation speed 18000r/min,high loads on crews,short lifetime of screw(8000-18000h)
Installation	Only a few spare parts,canbe installed and adjusted separately	Complex construction,needs special technical support for installation
Maintenance	Only replaced air filter and water filter,easy maintenance and low cost	Many spare parts and less maintenance cycle,high cost

√ Simple

One screw rotor and two gate rotors which are positioned at right angle to the axis constitute two compressing rooms. Therefore, the screw rotor with six grooves compresses as many as 12 times per rotation.

√ Quietness

Without applying thrust load to the axis direction of the rotor, the force in the circumference direction rotates quietly with good balance. As a result, the load to the bearing is lightened, minimizing the generation of noise or vibration.

√ Durability

The gate rotors are rotated following the rotation of the screw rotor along its gear. The water film formed on the screw rotor's gear and the free floating mechanism maintains the high efficiency for a long time (in case of water lubrication).

√ High Efficiency

Since the lubrication water is jetted in the compressing process, the compression is done smoothly under almost even temperature, realizing ideal, safe and highly efficient compression with slow rotation (in case of water lubrication).
