How it works
Oil free screw compressors are air-cooled, twin-shafted, positive displacement machines. Each contains two rotors (male and female) which rotate in opposite directions as a result of synchronized gears which are located outside the compression chamber.
Thus the compressed gas can be said to be completely ‘oil-free’.
The internal compression ratio is attained, and the gas is discharged through the outlet into the delivery pipe. Our asymmetrical 4+3 screw section is especially well adapted to low pressure operation.
HCS series
The single-stage, screw type compressor HCS series are produced as standard units suitably customized with an extensive range of accessories, or optional configurations which can provide customized solutions.
Range
Flows to 8500 m3/h / 5000 CFM.
Pressure to 3.5 bar gauge / 50 Psig.
Vacuum to 350 mbar abs. / 20 inch Hg. |
