Finally! Common Test Standards for Air Compressors


Common Test Standards for Air CompressorsOne major development in the field of dryers and air compressors was adopting a common set of test standards. On top of that, test results will now be properly reported thanks to a third party verification programme that was implemented. This major development was accomplished by the Compressed Air and Gas Institute (CAGI). People who use this equipment can be able to make comparisons when they want to purchase dryers and air compressors.

The Compressed Air And Gas Institute has a performance verification program that they sponsor for refrigerated compressed air dryers. The aim of the program is provision of a commercially and uniform practical means of verifying ratings of the participants. All participants must comply with the set standards and guidelines in order to be eligible for this program.

Members of CAGI have always been at the forefront in developing standards for equipment related to air compressors and dryers. The institute has worked with the International Organization for Standardization, European Committee of Compressors, Vacuum Pumps, and Pneumatic Tools and other bodies related to developing standards for gas systems equipment trying to make a unified system for making the best air compressors for home and garage use when it comes to safety of using and storing air compressors (read more over at

A useful tool in calculating energy for the compressors is the using the cost of power, commonly known as the power cost formula. Power cost is equivalent to the brake horsepower being used by the compressor multiplied by the factor of conversion of .746, multiplied by the operation hours, multiplied by the cost of electricity per kilowatt hour in the locality. The result is then divided by the efficiency rating of the motor.

This information should be published on the data sheets detailing the performance of the compressor as provided by the manufacturer. Such information is very useful in helping the consumer make comparisons and select the product that best meets their needs. However, some quack manufacturers tend to provide inaccurate information misrepresenting the information of their products. Therefore, the consumer may purchase a product that is deemed to have a higher performance rating only to end up disappointed. That is where the CAGI comes in. to ensure that the information provided by the manufacturer on their data sheet is accurate.

Who can participate?

Common Test Standards for Air CompressorsParticipation is open to all manufacturers and is voluntary. Participants do not have to be CAGI members. It is just a standard measure to ensure that consumers have the right information with regard to the measurements. The main advantage is that manufacturers who have gone through this procedure will tend to appear more legitimate to the public thus more sales.
How is a manufacturer identified for participation?

The manufacturers who have participated and their results are to be posted on the CAGI website. Manufacturers who have participated and passed the test verification procedures of the program will have the benefit of utilizing the CAGI verification seal on their items, product literature and specifications sheet. This is to prove to the public that the products of the said manufacturer have passed the air flow capacities and efficiencies.

What is being verified?

The information being verified is the one that manufacturers who are participating publish on the data sheets that are available at the CAGI website. Information that is on these data sheets include product performance and the information used during the application and specification decision making process.

How the verification process works

A CAGI administrator selects test samples on a random and regular basis of the equipment in order to prove that it meets the certified performance ratings of the manufacturer. Every participant will have two units tested annually. The items to be tested will be randomly selected from the manufacturer or distributor by the program administrator. If the selected unit does not pass the test procedure, then the manufacturer will have the option of having a second unit tested. If the second unit still fails the test procedure, the manufacturer is expected to adjust the rates on their published information based on the results within thirty days. Failure to do this leads to immediate expulsion from the program.


With the adoption of these industry standards and guidelines, better quality dryers and air compressors are now being produced. In a bid to achieve more sales and better numbers, manufacturers have resulted to producing more efficient products in order to withstand the competition. This is a commendable initiative from CAGI which will help consumers purchase better machines for their jobs thus reducing operating costs and attaining more profits.
