CAGI: why fit, form and function matter when sourcing centrifugal compressor maintenance parts
The Compressed Air and Gas Institute lays out why replacement parts built to the original spec - not just parts that physically fit - keep a centrifugal compressor's efficiency, warranty cover and reliability intact.
Illustrative photoCAGI's centrifugal compressor section lists Atlas Copco, FS-Elliott, Hanwha Power Systems, Ingersoll Rand and Sullair as members; the piece frames maintenance parts around fit, form and function rather than price alone.
Its example is an air filter: one built to a lower micron rating with more pleats filters more surface area than a generic part rated to looser tolerances, which can let larger particles reach downstream components.
CAGI's recommendation is to confirm a part's specification against the compressor's documentation before it goes in, whichever supplier it is sourced from.
