Industrial Rotary Screw and Vane Compressors

Compressors are machines that increase the pressure of a contained gas by reducing its volume. This means that they push a gas into a smaller space by compressing it and release it at different pressure levels when necessary, performing a variety of functions in the process. There are different types.

  • Industrial rotary screw compressors work by using two screws that push gas into the release chamber
  • Oil-filled rotary screw compressors utilize oil for a smoother run and act as a seal when pushing gas into the release chamber
  • Dry screw compressors increase pressure with perfectly aligned screws that do not allow air to escape. They are effective but have lesser pressure decreases due to the lack of the oily seal found in their oil-filled counterparts.
  • Rotary vane compressors work with bladed rotors. The oil-filled version produces more pressure as opposed to a dry compressor and can reach levels of 90% efficiency
  • Both have similar technology, quiet and run on fuel or with electric motors.

Rotary screw and vane compressors will do the same job effectively but the screw type produces air more efficiently over the lifetime of the compressor.
