The DSP oil-free rotary-screw air compressor is available in variable-speed and fixed-speed versions. Features include stainless steel first- and second-stage rotors; patented PTFE-free coatings to ensure high-quality air; and an oil-mist remover to prevent oil mist from venting into the atmosphere. A PQ wide-mode speed adjustment provides greater output at lower pressures, and a Hi-Precooler provides cooling and thermal protection. The unit is also designed for low sound levels and vibration isolation.
