Product Features
The air-intake temperature of the second stage is decreased by the strengthening oil-injected cooling after the first stage compression. The air is isobaric compressed. Each stage compression ratio is much more lowered than that of single stage compression work. It greatly decreased return leakage between rotors, highly increased volumetric efficiency and the diabatic efficiency and accordingly promoted compressed air capacity. Two stage compressor air capacity can be 15% higher than single stage compressor and save energy as much as 15%.
