Working Mechanism

  • These compressors have two interlocking helical screws / rotors that turn in opposite directions inside a casing.
  • The rotors have a specific profile, allowing them to mesh together closely without touching each other.
  • As the rotors turn, the air gets drawn in through an inlet port and gets trapped between the rotors and the casing.
  • As the rotors continue to turn, the air volume between them decreases, which causes compression.
  • The compressed air is then forced out through a discharge port into a storage tank or a pneumatic system.
