LGGPM-350 Air-cooled permanent magnet two-stage variable-frequency screw air compressor

LGGPM-350 Air-cooled permanent magnet two-stage variable-frequency screw air compressor

 The LGGPM-350 features a robust 250 kW power output, delivering stable compressed air at 55 m³/min under 0.7 MPa pressure. Its independent air duct system scientifically separates the air intake for filtration, cooling, and overall operation, complemented by a biomimetic centrifugal fan to provide a cool and stable operating environment for high-power units.

1. The independent air duct system features separate channels for air filtration, heat dissipation, and the entire unit, preventing hot air recirculation and achieving higher cooling efficiency.

2. The dedicated air intake filter, paired with a U-shaped soundproof sealing strip, provides simultaneous dust prevention and noise reduction while offering easy maintenance and replacement.

3. The 250 kW system employs a permanent-magnet two-stage compression configuration, delivering superior isothermal compression efficiency and achieving approximately 10% higher displacement per unit power compared to single-stage configurations.

4. A high-quality bionic centrifugal fan with stable air pressure and low noise, providing ample cooling airflow for high-power air-cooled units.

5. The AirLink IoT remote power-on/off function allows one-click device operation via mobile devices or PCs, enabling flexible alignment with production schedules.
