Depends on configuration
The LGGPM-100 supplies two-stage PM VSD compression in the 75 kW power class for shared plant air systems. Air delivery is 16.5 m³/min at 0.8 MPa, with a DN65 outlet and a unit size of 1980 × 1480 × 2130 mm.
The DN65 connection and pressure-specific airflow figures provide practical reference points when reviewing a station upgrade. Check that the existing dryer and filters can handle the selected operating point without excessive pressure loss.
1. 75 kW capacity for a plant air station
The LGGPM-100 delivers 16.5 m³/min at 0.8 MPa with a 75 kW motor. This operating point supports assessment of a station upgrade based on actual plant demand.
2. Two-stage compression with intermediate cooling
Air passes through first- and second-stage compression, with oil-mist cooling between stages. Splitting the pressure rise helps manage the load on the compression system.
3. Direct PM drive with demand-based speed control
The permanent magnet motor, inverter and direct transmission form the drive system. Compressor speed responds to changes in demand while the local controller presents operating information.
4. Variable-speed centrifugal fan cooling
The 75 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. Defined dimensions and handling load
The unit measures 1980 × 1480 × 2130 mm and weighs 2100 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 17.5 m³/min at 0.7 MPa and 12.5 m³/min at 1.0 MPa, allowing selection at the pressure the process needs.
7. Oil filtration and planned servicing
The lubricating circuit incorporates oil filtration and oil-air separation. The cabinet layout allows these systems to be included in a planned maintenance routine alongside the intake filter and cooler.

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 air station with a DN65 distribution connection, provide average and peak consumption, working hours and pressure losses to the point of use. Use 16.5 m³/min for the 0.8 MPa duty point.
Electrical and cooling provision: Check the 75 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 1980 × 1480 × 2130 mm cabinet, 2100 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-100 provide at different pressures?
Air delivery is 17.5 m³/min at 0.7 MPa, 16.5 m³/min at 0.8 MPa, 12.5 m³/min at 1.0 MPa and 11.2 m³/min at 1.2 MPa. Specify the pressure required by the application when selecting the configuration.
What cooling arrangement does this 75 kW model use?
The LGGPM-100 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.
How much lubricating oil is specified for this model?
The lubricating-oil quantity is 54 L. Follow the supplied filling, level-check and maintenance procedures; the amount used during a particular service operation depends on the procedure and the oil remaining in the system.
What should be checked when connecting a DN65 air outlet?
Confirm the supplied connection details, isolation arrangement and pipework support. Check pressure loss and the flow ratings of the dryer, filters and distribution line at the selected pressure.
