Depends on configuration
The LGGPM-350 is a 250 kW two-stage PM VSD model for central stations evaluating higher airflow through a DN100 interface. Air delivery is 54.0 m³/min at 0.8 MPa, with a DN100 outlet and a unit size of 3776 × 2126 × 2523 mm.
A shared cabinet size does not mean identical capacity or handling requirements across models. Use the LGGPM-350's own flow, power and weight when checking station expansion, foundations and downstream equipment.
1. 250 kW capacity for large production networks
The LGGPM-350 delivers 54.0 m³/min at 0.8 MPa with a 250 kW motor. This output supports evaluation of higher-capacity station duty at the selected pressure.
2. Two stages with oil-mist cooling between them
Compression is completed in two pressure steps. Cooling between the stages helps manage the thermal load before final compression to the selected operating pressure.
3. Variable-speed permanent magnet drive
The permanent magnet motor is controlled by a variable-frequency drive and connected through direct transmission. This allows compressor speed to respond to changes in plant demand.
4. Variable-speed axial fan cooling
The 250 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. Model-specific handling and installation data
The unit measures 3776 × 2126 × 2523 mm and weighs 6450 kg. These figures support delivery-route and room-layout checks; allow additional space for service and cooling airflow.
6. DN100 outlet with pressure-specific performance
The DN100 air outlet connects the compressor to the air system. Delivery is 55.0 m³/min at 0.7 MPa and 46.0 m³/min at 1.0 MPa, allowing selection at the pressure the process needs.
7. Remote monitoring for station maintenance
The series IoT system supports operating-data checks, fault warnings and maintenance reminders. The supplied communication equipment and network arrangements should be specified for the project.

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 large production-air network or a central-station capacity upgrade, provide average and peak consumption, working hours and pressure losses to the point of use. Use 54.0 m³/min for the 0.8 MPa duty point.
Electrical and cooling provision: Check the 250 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 3776 × 2126 × 2523 mm cabinet, 6450 kg unit weight and DN100 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.

What airflow does the LGGPM-350 provide at different pressures?
Air delivery is 55.0 m³/min at 0.7 MPa, 54.0 m³/min at 0.8 MPa, 46.0 m³/min at 1.0 MPa and 40.0 m³/min at 1.2 MPa. Specify the pressure required by the application when selecting the configuration.
What cooling arrangement does this 250 kW model use?
The LGGPM-350 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.
Can the installation be planned using another model with the same cabinet dimensions?
Use this model's own installation and handling data. The LGGPM-350 weighs 6450 kg, and its electrical and airflow requirements must be checked separately even where cabinet dimensions are shared.
Does VSD guarantee a fixed energy-saving percentage?
Actual savings depend on the demand profile, pressure setting, operating hours and the equipment being compared. Assess performance at the required duty point and review the expected loading pattern for the complete air system.
