Funktionsweise
Permanent-magnet synchronous motor + variable-frequency drive + meshing screw compression: the motor directly drives the screw rotors to progressively compress air from the inlet to the discharge port; an oil separation system reduces oil content to ≤3 ppm. The inverter adjusts motor speed based on system pressure to maintain constant-pressure output and achieve energy savings. Soft-start reduces mechanical shock.
