Description

Comparisions

	Water-lubricated Oil-free Single Screw Air Compressor	Dry Oil-free Double Screw Air Compressor
Working Principle	Water-lubricated Oil-free Single Screw	Dry Oil-free Double Screw
Air Quality	100% Oil Free	Oil in the gear
Air Purity	Clear air after purified by water	Contain dust and oil stain
Lubrication Media	Pure Water	Dry
Air Temp	Less than 55℃	About 180~200℃
Compression	Single-Stage	Two-stage
Cooling method	Don’t need cooling system	Need interstage and after Cooling system
Structure	Simple and Balance Structure	Radial load is not balance
Vibration and Noise	Low vibration and noise	High frequency noise due to the two screws
Durability	Ideal Rotation speed 3000r/min, theoretically zero load. Long lifetime of the screw (30000h) and star wheel (50000h)	Rotation speed 18000r/min, high loads on screws. Short lifetime of screw (8000~18000h)
Maintenance	Only air and water filter elements	More spare parts
