Vilter VSG™ Single-Screw Compressors for Natural Gas and Process Applications

Vilter’s line of single-screw compressors offer unique advantages making them a perfect fit for natural gas and process gas applications. 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 VSG Single-Screw Rotary Compressor

gaterotors. Gas compression occurs when the individual fingers of each gaterotor sweep through the grooves of the main screw as the

The Vilter Advantages: • Balanced main rotor with no axial

or radial loads

screw rotates. Fewer moving parts means fewer overhauls resulting in significant maintenance savings.

• Low bearing loads • Clockwise rotation models available • High suction pressures available

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

• Parallex ™ Slide System • Low noise levels

In addition to supplying the bare compressor, you can also count on our

• Low maintenance costs

team of engineers to design and manufacture complete packages for the natural gas and process industries.
