Features
- Vacumm pressure ranges from 33 mbar to 1013 mbar.
- Gas emmision ranges from 3 to 20400 m3
- Near-isothermal compression, pollution-free.
- No lubrication required in the working chamber, thus absolutely oil-free.
- Capable of handling nearly all gases and vapors.
- Able to process small amounts of entrained liquids.
- Easy maintenance, high reliability.
- Low noise, virtually no vibration.
- wide choice of materials, therefore applicable nearly everywhere.
