A screw compressor is a type of positive displacement compressor widely used in various industrial applications for generating compressed air. It operates based on the principle of two rotating helical screws (rotors) that compress the air as it moves through the compression chamber.

Product Description

Step by Step Screw Operation

  1. An opening valve sucks gas into the compressor chamber. Located in the chamber are the two screw rotors; when the machine is on, they will rotate at high speeds.
  2. As the impellers rotate, they trap and isolate air in the cavities between the rotors, thus moving the air down the chamber.
  3. The chamber decreases in size and is moved away from the opening valve. As the volume decreases, the pressure increases.
  4. Pressurisation builds and thus the air is condensed.
  5. Air pressure will trigger the compressor’s discharge valve to open, allowing the pressurised air to enter a receiver or other holding tank.
  6. Air is compressed and can be transferred to downstream equipment such as dryers and oil/water separators for drying and contamination removal.
