The Clean Air Solution You Need
Both oil-free and oil-flooded compressors can be designed with downstream mechanical filtration in order to remove all impurities in the air. However, oil-free compressors don’t introduce oil or other lubricants into the air compression process, providing an additional safeguard for highly sensitive applications.
What is Oil-Free Air?
Compressed air purity is defined by ISO 8573.1 purity classes, with oil-free applications requiring Air Quality Classes 1 or 0.
- ISO Class 0 is based on the specifications of the particular application, below the ISO Class 1 maximum total oil concentration, which can be achieved with both oil-free and oil-flooded compressors.
- The ISO 8573.1: 2010 table outlines the standards for each of the compressed air purity classes. The table contains the maximum contaminant levels for each of the compressed air quality classes along with the test methods and analytical techniques for each type of contaminant.
