A Chinese-language interactive guide to the structure, operation, and configurations of a Sauer WP 400 compressor.

Landing page captured for the 2026-09-29 issue.
For
Readers studying compressor structure and operation
Worth noticing
The page compares drawing configurations 7205 and 7204, including dimensions, weights, connection sizes, and which version has an attached cooling-water pump.

Field notes

The guide cites manual page ranges throughout, including pages 22–28 for the system overview and 35–36 for the flow diagram. Its configuration comparison distinguishes the 7205 and 7204 drawings, noting that the displayed overall lengths are inferred from drawing dimensions rather than printed as total lengths. It also flags where the teaching model simplifies undocumented geometry and operating details.
