  • CAGI to verify compressor claims

    The compressed air industry is taking a step that will clear the air about the performance of its equipment. For the first time, many compressed air equipment manufacturers will submit their 50 hp to 200 hp lubricated rotary-screw compressors and 200 cfm to 1,000 cfm refrigerated air dryers to an independent laboratory for performance testing.
