Abstract
A two-stage oil-injected screw air compressor includes an integrated compression casing, and the integrated compression casing further includes a first stage compression chamber, an intermediate cooling channel, and a second stage compression chamber parallel stacked in the integrated compression casing. A straightforward oil injector aims at the intermediate cooling channel to spray lubricating oil into the intermediate cooling channel.
