SE-75 Permanent Magnet Variable Frequency Screw Air Compressor

The SE-75 features a power output of 55 kW and a large displacement of 9.1 m³/min; equipped with an IE4 permanent magnet motor and a three-

stage oil-gas separation system, it provides continuous and stable high-pressure air for heavy-duty manufacturing, large-scale auto parts production, and general industrial applications.

1. 55 kW high power output and a large displacement of 9.1 m³/min: featuring 75 HP power reserve and maintaining a continuous output of 9.1 m³/min at 0.8 MPa, enabling seamless operation for multi-station gas requirements in large workshops, heavy machinery applications, and similar scenarios.

2. IE4 Permanent Magnet Motor + Variable Frequency Soft Starter: The IE4 high-efficiency permanent magnet IP23 motor, when paired with a variable frequency drive (VFD) starter, features a low starting current, minimal grid impact, fast load response, and consistently maintains high operational efficiency.

3. High-capacity heat dissipation ensures no reduction in output under heavy loads: the large-diameter suction-type fan works synergistically with the dual exhaust ports at the bottom for effective heat dissipation; equipped with a 26L lubricating oil capacity, it maintains stable and controllable exhaust temperatures even during continuous 24-hour operation.

4. G1 1/2 large-diameter outlet provides lower pipeline pressure loss: The flanged large-diameter outlet interface, combined with a robust chassis measuring 1200 × 1100 × 1700 mm, reduces pipeline pressure drop and enhances the end-user gas delivery experience.

5. Five-layer electrical protection ensures more reliable operation: with comprehensive protection against phase loss, overload, undervoltage, overvoltage, and phase imbalance, the system maintains stable operation even under grid fluctuations.
