Antwerp, 3rd September 2007: Atlas Copco has yet again proven its world leadership in air-compressor manufacturing – with new ISO 8573-1 CLASS 0 certificates for oil-free industrial air compressors in the centrifugal, tooth, scroll and water-injected screw ranges. The ‘Class 0’ rating for these industrial compressors is the next step in a continuous drive in innovation that began with the certification of the Z screw compressor range in 2006, the first compressors in the world to be TÜV certified ISO 8573-1 CLASS 0.

With these latest ‘Class 0’ certificates, Atlas Copco can offer its customers a wide range of optimal and efficient compressor solutions capable of meeting every compressed-air application where high air purity is critical.

Testing of Atlas Copco oil-free compressors was carried out by the renowned independent Technische Überwachungs-Verein (Technical Monitoring Association, or ‘TÜV’), using the most stringent test methods available and simulating realistic industrial environments. Even with such rigorous testing, the TÜV found no traces of oil in the output air stream under any of the test conditions.
