Features of Single-Stage Frequency Conversion Twin-Screw Air Compressor

  1. Energy saving & high efficiency: Frequency conversion drive automatically adjusts speed according to air demand, avoiding frequent starts/stops and optimizing energy usage.
  2. Stable operation: High-precision twin-screw rotors reduce friction loss, ensuring long-term, stable performance.
  3. Low oil content: Advanced oil separation system ensures exhaust oil content ≤ 3ppm, meeting strict air quality requirements.
  4. Intelligent control: Integrated intelligent control system enables remote monitoring, data logging, and automatic fault diagnosis for user-friendly operation.
  5. Multiple cooling methods: Supports both air-cooled and water-cooled options to suit various environments and operational needs.

Working Principle

  1. Suction stage: As the screw rotors turn, air enters the compression chamber through the inlet, forming a fixed volume.
  2. Compression stage: The intermeshing rotors reduce the gas volume, increasing pressure while lubricating oil is mixed in for cooling and sealing.
  3. Exhaust stage: Once compressed to the set pressure, air is discharged and lubricating oil is removed via the oil-air separation system, resulting in clean compressed air.
  4. Frequency conversion control: The inverter adjusts motor speed for optimal energy efficiency under varying load conditions, minimizing electricity waste.
