High Efficiency & Reliability for Industrial Applications

Everything You Need to Know About Centrifugal Air Compressors

Centrifugal air compressors use high-speed rotating impellers to convert kinetic energy into pressure energy. Known for their oil-free operation, high efficiency, and large capacity, these compressors are widely used in industries like power generation, chemical processing, and air separation.

Working Mechanism Section

How Do Centrifugal Air Compressors Work?
  • Air Intake: Ambient air is drawn into the compressor.
  • Kinetic Energy Conversion: High-speed impellers accelerate the air, increasing its velocity.
  • Diffuser Stage: The velocity is converted into pressure as the air slows down in the diffuser.
  • Multi-Stage Compression: For higher pressure, the process is repeated across multiple stages.
