Very cost-effective for handling high volumes of gas in vapor recovery. Low maintenance and high reliability are inherent because they have few moving parts. There are no valves, rings, or packing to wear out or cause loss of efficiency.
Smooth operation results from no unbalanced forces.
No special foundation is required, and there are no piping vibrations from pressure pulsations. All iron or steel construction with no copper or brass making these compressors compatible with natural gas: sweet or sour.
Rotary Screws are by far the most efficient and reliable way to move gas.
