Simplified Test Codes for Blowers

Blower manufacturers offer packaged centrifugal compressors and blowers in both a serial-production manner and made to order. The blower package is fitted with all of the necessary ancillary devices for operation and is marketed as a standard offering by manufacturers.

Existing test codes provide for detailed measurement of the core, or bare blower, but no test standard was available to measure a blower’s package performance; therefore, the Compressed Air and Gas Institute (CAGI) took on the task of developing supplementary codes referencing the existing flange to flange blower — compressor codes ISO 1217 and ISO 5389. The industry and the users of blowers needed a standard method of rating performance of the entire package. This provides users with relevant, accurate information regarding performance of the entire package, true wire-to-air performance.
