Depends on configuration
The LGGPM-425 is a 315 kW air-cooled two-stage PM VSD compressor for large central stations with substantial production demand. Air delivery is 62.0 m³/min at 0.8 MPa, with a DN125 outlet and a unit size of 5426 × 2190 × 2635 mm.
At this capacity, the compressor should be selected as part of the complete station: electrical provision, ventilation, delivery access and treatment capacity all matter. Use the pressure-specific output rather than the model designation to assess the intended duty.
1. 315 kW output for major plant air demand
The LGGPM-425 delivers 62.0 m³/min at 0.8 MPa with a 315 kW motor. The defined pressure point supports assessment of a large central station against the production load profile.
2. Two-stage compression for high-volume supply
Compression is split between two stages, with oil-mist cooling between them. This arrangement manages the pressure and temperature rise through the compression process.
3. PM VSD control with direct transmission
The permanent magnet motor, variable-frequency drive and direct transmission form the main drive system. Speed control responds to changes in air consumption across the selected operating duty.
4. Variable-speed axial fan cooling
The 315 kW air-cooled package uses variable-speed axial fan cooling. The axial fan arrangement supports cooling airflow through the package; plan adequate inlet air and a clear hot-air discharge route.
5. Complete handling data for a large enclosure
The unit measures 5426 × 2190 × 2635 mm and weighs 8220 kg. These figures support delivery-route and room-layout checks; allow additional space for service and cooling airflow.
6. DN125 outlet with pressure-specific performance
The DN125 air outlet connects the compressor to the air system. Delivery is 65.0 m³/min at 0.7 MPa and 55.0 m³/min at 1.0 MPa, allowing selection at the pressure the process needs.
7. Station monitoring and maintenance support
A local touch-screen controller provides operating information, and IoT support enables remote data checks, fault warnings and maintenance reminders when configured and connected.

Air-delivery values correspond to the individual pressure points shown; they are not a VSD minimum-to-maximum flow range. Confirm the required pressure configuration and site conditions when ordering. Motor speed is a specification reference, not a stated VSD speed range; compare noise levels under equivalent measurement conditions.
Pressure and demand: For a high-capacity industrial station serving major production loads, provide average and peak consumption, working hours and pressure losses to the point of use. Use 62.0 m³/min for the 0.8 MPa duty point.
Electrical and cooling provision: Check the 315 kW motor and 380 V / 3-phase / 50 Hz supply with the installation team. The axial fan system requires an unobstructed cooling-air inlet and a suitable hot-air discharge route.
Handling and connections: Plan for the 5426 × 2190 × 2635 mm cabinet, 8220 kg unit weight and DN125 connection. Obtain the installation drawing and allow the required service and ventilation clearances.
Air quality and site conditions: Specify the receiver, dryer and filters for the required process air quality. Report high temperature, high humidity, severe cold, altitude or heavy dust so that the proposed configuration can be reviewed for the actual site.

Review qualification documents
What airflow does the LGGPM-425 provide at different pressures?
Air delivery is 65.0 m³/min at 0.7 MPa, 62.0 m³/min at 0.8 MPa, 55.0 m³/min at 1.0 MPa and 47.0 m³/min at 1.2 MPa. Specify the pressure required by the application when selecting the configuration.
What cooling arrangement does this 315 kW model use?
The LGGPM-425 is air-cooled and uses variable-speed axial fans. A process cooling-water circuit is not required for this version; adequate cooling-air supply and hot-air discharge remain essential.
What handling weight should be used for the LGGPM-425?
The unit weight is 8220 kg. Confirm the lifting points, unloading procedure, delivery access and support requirements in the supplied installation documents before moving the machine into position.
Is the air-cooled model suitable for every site environment?
High temperature, high humidity, severe cold and heavy dust need a separate configuration review. Provide the actual site conditions so that ventilation and any non-standard provisions can be assessed before ordering.
