International Air Quality Class Standards

ISO 8573-1 Air Quality Standard

N/A ISO 8573-1, the international standard for compressed air quality, defines the amount of contamination permissible in compressed air.
The ISO standard identifies three primary forms of contamination in compressed air systems - solid particles, water and oil Contaminants are classified and assigned a quality class, ranging from Class 0, the highest purity level, to Class 6, the most relaxed.

HPR and HPRN series refrigerated air dryers offer the perfect balance between technology and simplicity to dry compressed air systems to ISO 8573-1 Air Quality Class 4 to 5 - pressure dew points.

Option Pre-Filtration

N/A NGF series - PF grade filtration - removes solid and oil contaminants from the air stream before entering the dryer.

ISO Air Quality Class:
  • Solids - Class 2
  • Remaining Oil - Class 4
  • Removes solids 1.0 micron and larger
  • Remaining oil content 2.0. mg/m³

Option After-Filtration

N/A NGF series - HF grade filtration - provides high efficiency oil removal protecting downstream equipment .

ISO Air Quality Class:
  • Solids - Class 1
  • Remaining Oil - Class1
  • Removes 99.999+ % of solids ≥ 0.01 micron
  • Remaining oil content < 0.01 mg/m3
  • 1 Conditions for rating dryers are in accordance with ISO 7183 (Option A2). Compressed air at dryer inlet: 100 psig (6.7 bar) and 100 ºF (38 ºC); ambient air temperature: 100 ºF (38 ºC); operating on 60 Hz power supply.
