With a growing concern for the environment in which we live, along with the products we consume, not only Oil Free, but Contaminant Free air is quite important. To address these concerns a new, more rigorous, class was added to the existing purity classes: ISO 8573-1:2001 Class 0.
The foundation of Hitachi Innovation is derived from more than 50 years of Oil Free Compressor technology, with the world introduction of Hitachi Oil Free Reciprocating compressors in 1954. This history has allowed Hitachi to become one of the worlds leading providers of Oil Free Dry Screw products.
Continuing our pioneering spirit with societal responsibility, Hitachi embarked upon a certification of ISO 8573-1:2001 Class 0 for the Hitachi DSP Series Oil Free Rotary Screw Compressor (15-240kW). To validate our findings for consumer knowledge, third party laboratory testing was contracted with a positive result to standards, which enables Hitachi to provide a variety of Innovative, Technologically Superior, and Value Oriented Product for our Customers. When applications are critical and risk free air is essential to providing superior products, no downtime, and protecting your reputation Class 0 is a must. Class 0 is risk free air.
