Two Stage Screw Air Compressor

The two-stage air end features the design of equal low internal pressure ratio with low leakage rate during the compression process, which promotes enormously the volumetric efficiency of the whole process (the volumetric efficiency of the two-stage air end is upto 93% while that of single stage air end is atmost 90%). The two stage air end features higher energy savings than the single stage air end .Under the same working conditions with equal discharge volume and pressure, two stage air end save 15% more on energy consumption than single stage air ends. In them ean time, under the same working conditions with equal energy consumption and discharge pressure, two stage air ends get an extra 15% discharge volume over single stage air ends.
