Oil-free Design

Hitachi Oil-Free Scroll Technology is 100% oil-Less. The complete oil free structure is suitable for ISO 14001 factories.


Proprietary Scroll Wrap

(Patent USP 6808373)

Hitachi’s patented wrap design with Labyrinth seal provides superior performance and reliability. Alumite surface treatment also contributes to extended scroll life.


Scroll Compression Principle

scroll air end

To initiate compression, two scroll members comprised of :


  • 1. Orbiting scroll member and 2. fixed scroll member are mated to create compression chambers. The continual rotary movement of the orbiting scroll member compresses air from the atmosphere creating oil-free and contaminant-free air.
