CAGI data sheet

A CAGI data sheet is the compressed-air industry’s standardized performance disclosure, published under the Compressed Air and Gas Institute’s third-party verification program. Every covered model has a single-page sheet that reports the same fields in the same units under the same test method, making compressor-to-compressor comparison reliable.

What it is

CAGI data sheets are produced under the PNEUROP / CAGI / ISO 1217 test code. For rotary compressors, the headline fields are full-load capacity (SCFM at rated discharge), full-load package input kilowatts, specific power (kW per 100 SCFM), and inlet conditions. For variable-speed compressors, the sheet adds turndown range and part-load efficiency. Third-party verification audits a sample of submitted sheets each year.

Why it matters

Before CAGI, manufacturer-published flow numbers varied by test method. Different reference conditions, different inlet losses, and different measurement points could shift apparent SCFM by 10 percent or more. A CAGI sheet eliminates that ambiguity. For any energy-sensitive purchase, specific power on the CAGI sheet is the right number to compare.

How it is used in our catalog

We link to the CAGI data sheet for every covered model in the compressor catalog wherever the manufacturer participates. The sheet is the source of truth for SCFM and kW at rated pressure. Browse rotary screw archives for side-by-side CAGI links.

Common questions

Are CAGI sheets required by law?

No. They are voluntary, but participation is the industry norm and absence is informative.

Does CAGI cover piston compressors?

The verification program is strongest for rotary screw, scroll, and centrifugal. Piston coverage is more limited.
