Depends on configuration
The LGGPM-125 is the 90 kW two-stage PM VSD option for plants evaluating a higher-capacity supply through a DN65 outlet. Air delivery is 19.8 m³/min at 0.8 MPa, with a DN65 outlet and a unit size of 2360 × 1580 × 2250 mm.
Its cabinet is taller and narrower than some other models in the range, making the complete dimensions important when reviewing the available location. Electrical capacity and cooling-air routing should be checked together with the required operating pressure.
1. 90 kW output at a defined duty point
The LGGPM-125 delivers 19.8 m³/min at 0.8 MPa with a 90 kW motor. Pressure-specific capacity helps align the compressor with the plant load instead of relying on the model number alone.
2. Staged compression for industrial air supply
Two compression stages divide the total pressure increase. Oil-mist cooling between the stages supports thermal management within the compression assembly.
3. PM VSD operation with direct transmission
The permanent magnet motor and variable-frequency drive adjust output to changing demand. The direct-drive arrangement avoids routine belt adjustment in the motor-to-airend transmission.
4. Variable-speed centrifugal fan cooling
The 90 kW air-cooled package uses variable-speed centrifugal fan cooling. The cooling-air system supports heat removal without a cooling-water circuit; keep the inlet and discharge paths clear.
5. Cabinet proportions for room-layout planning
The unit measures 2360 × 1580 × 2250 mm and weighs 2570 kg. These figures support delivery-route and room-layout checks; allow additional space for service and cooling airflow.
6. DN65 outlet with pressure-specific performance
The DN65 air outlet connects the compressor to the air system. Delivery is 20.8 m³/min at 0.7 MPa and 16.9 m³/min at 1.0 MPa, allowing selection at the pressure the process needs.
7. Front-panel operating checks
The touch-screen interface gives operators a local view of machine operating information, supporting routine checks before and during production shifts.

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 plant-level air network with variable production demand, provide average and peak consumption, working hours and pressure losses to the point of use. Use 19.8 m³/min for the 0.8 MPa duty point.
Electrical and cooling provision: Check the 90 kW motor and 380 V / 3-phase / 50 Hz supply with the installation team. The centrifugal fan system requires an unobstructed cooling-air inlet and a suitable hot-air discharge route.
Handling and connections: Plan for the 2360 × 1580 × 2250 mm cabinet, 2570 kg unit weight and DN65 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-125 provide at different pressures?
Air delivery is 20.8 m³/min at 0.7 MPa, 19.8 m³/min at 0.8 MPa, 16.9 m³/min at 1.0 MPa and 14.3 m³/min at 1.2 MPa. Specify the pressure required by the application when selecting the configuration.
What cooling arrangement does this 90 kW model use?
The LGGPM-125 is air-cooled and uses variable-speed centrifugal fans. A process cooling-water circuit is not required for this version; adequate cooling-air supply and hot-air discharge remain essential.
Does the LGGPM-125 use an axial cooling fan?
The 90 kW LGGPM-125 uses variable-speed centrifugal fan cooling. Ventilation and exhaust routing should be designed around the supplied air-cooled configuration.
What should be checked if equipment-room height is limited?
The cabinet height is 2250 mm. Check the complete delivery route and the required overhead and maintenance clearances, using the installation drawing for the selected machine configuration.
