Miniature Screw Compressor

Model VSM from Vilter Manufacturing Corp. is a rotary, positive-displacement compressor that incorporates a main screw and two gate rotors. Its compact design has no external tubing on the compressor, no gearbox and an optional oil pump. Its Parallex slide system has capacity and volume slides that move independently of each other based on load, eliminating over- or undercompression and saving motor horsepower. The unit is controlled via the company's Vantage microcontroller for user-friendly operation, dual processing power and multiple languages.
