What is Compressed Air Testing and Why do you need it?

When testing industrial compressed air for contaminants, the International Organization for Standardization (ISO) in ISO-8573:1 identifies four types of contaminants vital for testing and removal: air, oil, water and microbial.

What is compressed air Testing?

Compressed air testing is simply a standardized test that can be used to analyze the quality of the air and detect any contaminants.

The international standardized test for compressed air contaminants is found in ISO 8573. It checks for the three most common contaminants: oil, particles, and water. The formatting for this test is ISO 8573-1:2010 [P:W:O].

Why do you need to test?

Compressed air manufacturers must test for contaminants and provide this information in the equipment specification sheets. Some of the contaminants that are present in compressed air include gases, microorganisms, oil, particles, and water. If these particles remain in the compressed air, they can make their way into the final product and contaminate it. Compressed air is considered a critical control point and therefore annual testing is also a requirement of ISO/FSCC22000, SQF and other food safety and pharmaceutical safety standards.
