Depends on configuration
The LGGPM-480 is the 355 kW model in this air-cooled two-stage range, with a listed air delivery of 69.5 m³/min at 0.7 MPa. It is intended for selection into central air systems where sustained plant demand calls for a high-volume compressor and carefully planned distribution equipment.
Two-stage compression, permanent magnet variable-speed drive and direct transmission form the core package. The specified 5426 × 2190 × 2635 mm enclosure, 8300 kg unit weight and DN125 outlet make installation access, floor support, ventilation and downstream equipment capacity key parts of the project review.
1. High-volume duty point
The LGGPM-480 delivers a listed 69.5 m³/min at 0.7 MPa from a 355 kW motor, providing a defined capacity for large central air systems.
2. Two-stage compression with interstage cooling
Compression is divided between two stages, with oil-mist cooling between them. This arrangement manages the compression process in steps rather than in a single stage.
3. Permanent magnet VSD with direct drive
The drive combines a permanent magnet motor, variable-frequency control and direct transmission to respond to changing air demand without a belt transmission stage.
4. Variable-speed axial cooling fans
For the 355 kW air-cooled model, the series specification identifies axial fan cooling with variable-speed control, supported by the cabinet's arranged cooling-air paths.
5. Controller visibility
The series touch-screen control system displays operating information and supports demand-based adjustment, helping operators monitor the compressor from the local panel.
6. Oil filtration and separation
The lubricating system combines oil filtration and oil-air separation to support the compression assembly. Select downstream treatment separately for the required process air quality.
7. Remote monitoring support
The series IoT system supports operating-data monitoring, fault warnings and maintenance reminders. Confirm the communication hardware, connectivity and enabled functions for the supplied configuration.

These values refer to the air-cooled LGGPM-480. Air delivery is listed separately for each pressure point; 1500 rpm is the tabulated motor speed, not a stated VSD operating range. Review site conditions and measurement conditions when comparing performance and noise.
Central-station sizing: Provide a demand profile covering normal production, peak demand and operating shifts. Review the selected pressure point together with dryer, receiver and distribution-system capacity.
Electrical and ventilation planning: Check the 355 kW motor and 380 V / 3-phase / 50 Hz specification with the project electrical team. Plan the cooling-air supply and hot-air exhaust route for the air-cooled package.
Handling and installation: Confirm delivery access and the handling plan for the 8300 kg unit. Allow for the 5426 × 2190 × 2635 mm enclosure, DN125 outlet and additional maintenance and ventilation clearances.
Process conditions: Specify the required air quality and the site's ambient temperature, altitude, humidity and dust conditions. Match air treatment and any non-standard provisions to the actual installation.

What is the airflow of the LGGPM-480 at different pressures?
Air delivery is 69.5 m³/min at 0.7 MPa, 66.6 m³/min at 0.8 MPa, 58.8 m³/min at 1.0 MPa and 52.0 m³/min at 1.2 MPa. Specify the required pressure point for selection.
Is this the air-cooled or water-cooled version?
This page covers the air-cooled LGGPM-480 with variable-speed axial cooling fans. The water-cooled range is a separate specification and should not be used for this page's dimensions or performance selection.
What size and weight should be used for installation planning?
Use the unit dimensions of 5426 × 2190 × 2635 mm and unit weight of 8300 kg as the starting point. Request the installation drawing, lifting details and required service clearances for the selected configuration.
Can operating information be viewed remotely?
The series supports an IoT management system for remote data monitoring, fault warnings and maintenance reminders. The quotation should identify the supplied communication equipment, network requirements and available functions.
