Air Quality
The compressed air at the compressor outlet contains the following impurities: Solid particles, Moisture, Oil from the compressor, Vapor substances present in the intake air.
Each equipment downstream of the compressor that operates with compressed air needs a
specific air quality level regarding the above-mentioned impurities, which are measured according to ISO 8573-1:2010 standard.
This standard defines with 3 sequential numbers the values of solid particles, moisture, and oil present in the air respectively, as shown
in the following example:
Depending on the characteristics of the air present at the compressor location, actions must be taken to control the values of the above parameters through filtration, dehumidification, and oil removal treatment.
Unless otherwise specified in technical documents, AIRON components require air quality according to ISO 8573-1:2010 7-4-4; AIRON filters with standard filtration grade of 25 μm ensure achieving grade 7, while the dew point below 3°C and oil content below 5 mg/m³ must be achieved through preliminary drying treatment and subsequent oil removal. The use of a 5 μm filtration grade, available upon request for all AIRON filters, improves component durability.
The use of lubricators now occurs only in certain applications due to environmental pollution concerns; however, their initial use requires ongoing maintenance as the oil's washing action removes the lubricating grease present on all pneumatic components at the time of assembly.
