Vilter‘s line of single-screw compressors for natural gas and process applications (VSG) is used in a variety of applications, including digester gas, fuel gas boosters, landfill gas, LNG boil-off, vapor recovery process gas and natural gas gathering.

These compressors have been designed with efficiency and versatility in mind, providing both performance and maintenance advantages.

The key is in the balanced design. The positive displacement rotary compressor uses a single main screw intermeshed by two opposing gaterotors. Gas compression occurs when the individual fingers of each gaterotor sweep through the grooves of the main screw as the screw rotates. Fewer moving parts mean fewer overhauls resulting in significant maintenance savings.

The balanced main screw results in ultra-low bearing loads and significantly decreased vibration and sound levels.

In addition to supplying the bare compressor, you can also count on our team of engineers to design and manufacture complete packages for the natural gas and process industries.
