Single Phase VFD for Air Compressor – 220V to 3-Phase 380V

A single phase VFD for air compressor lets you run a three-phase compressor motor from a regular single-phase 220V outlet – no grid upgrade, no phase converter. The SHZK 300-S3 is a purpose-fit 220V to 380V converter for air compressor: single phase in, three phase out, driving screw and piston compressors up to 18.5kW with soft start and pressure-holding sleep/wake logic.

Why Convert Your Compressor to Variable Speed?

  • Run a 3 phase air compressor on single phase without rewiring the workshop
  • 20-45% energy saving by matching speed to air demand
  • Soft start cuts inrush current and mechanical stress
  • Built-in PID pressure control; auto sleep when the tank is full
  • Works with 380V, 400V and 415V three-phase compressor motors
