CAGI Data Sheets: Comparing Blower Package Performance

CAGI Data Sheets are blower package performance sheets that allow air users to compare the efficiencies of different blower packages in a standardized format. Only CAGI member companies can utilize these sheets to present performance data. Most of the critical measures that aid the understanding of blower performance are documented on these sheets and, most importantly, can be verified by an independent third-party administrator.

With CAGI sheets, consumers now have a standard way to compare performance, and the independent verification process provides assurance that the numbers are accurate.

CAGI Data Sheets should not be considered an all-encompassing feature/benefit comparison for blower packages. The Fixed Speed Data Sheets only report performance at the blower’s full flow capability. Because demand in a pneumatic conveying or wastewater facility typically varies throughout the day, blower packages can produce flow below their full load capability. To understand the efficiency of a blower package during part load periods, you should work with a blower package salesperson.

Utilizing the data sheets is the fun part. For ease of comparison, every data sheet for similar types of blower packages is organized in the same way. At the top of the sheet, you will find the manufacturer and model of the package: fixed speed or variable frequency drive. Note that for fixed speed blower packages, all data assumes the blower is operating at full load, so it is important to take into account how your unit will be operating (for assistance, see your blower package sales expert).

Once you understand how to read and interpret CAGI data sheets you can make apples-to-apples efficiency comparison across blower technologies and manufacturers.

An efficient blower package, operated by a well-designed control system ensures you are getting maximum productivity at the lowest possible cost from your blower system. Armed with CAGI Data Sheets and a blower package expert, you have the knowledge to implement the best air system for your application and to keep the system at its optimal efficiency level for years to come.
