Depends on configuration
The LGGPM-75 is a 55 kW model for factories sizing a common air supply around a defined pressure and production load. Air delivery is 12.5 m³/min at 0.8 MPa, with a G2 outlet and a unit size of 1810 × 1430 × 2080 mm.
Its operating data allows the compressor to be assessed alongside the receiver, dryer and plant distribution network. The enclosure dimensions describe the machine itself; service and cooling-air clearance must be added when laying out the room.
1. 55 kW capacity for factory air networks
The LGGPM-75 delivers 12.5 m³/min at 0.8 MPa with a 55 kW motor. This rating helps assess a common air station supplying several production areas.
2. Two-stage pressure rise with oil-mist cooling
The compression load is divided between two stages, and oil-mist cooling moderates temperature between them. This arrangement supports the two-stage compression process across the stated pressure configurations.
3. Variable-speed response across production shifts
The permanent magnet VSD adjusts motor speed as air consumption changes between production periods. Direct drive transfers motor output to the airend without a belt transmission stage.
4. Variable-speed centrifugal fan cooling
The 55 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. Installation data for an existing compressor room
The unit measures 1810 × 1430 × 2080 mm and weighs 1810 kg. These figures support delivery-route and room-layout checks; allow additional space for service and cooling airflow.
6. G2 outlet with pressure-specific performance
The G2 air outlet connects the compressor to the air system. Delivery is 12.8 m³/min at 0.7 MPa and 9.6 m³/min at 1.0 MPa, allowing selection at the pressure the process needs.
7. Local operating visibility
The touch-screen controller displays operating information at the machine. Its interface supports routine pressure and status checks as part of plant maintenance.

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 common factory air network serving production shifts, provide average and peak consumption, working hours and pressure losses to the point of use. Use 12.5 m³/min for the 0.8 MPa duty point.
Electrical and cooling provision: Check the 55 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 1810 × 1430 × 2080 mm cabinet, 1810 kg unit weight and G2 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-75 provide at different pressures?
Air delivery is 12.8 m³/min at 0.7 MPa, 12.5 m³/min at 0.8 MPa, 9.6 m³/min at 1.0 MPa and 8.6 m³/min at 1.2 MPa. Specify the pressure required by the application when selecting the configuration.
What cooling arrangement does this 55 kW model use?
The LGGPM-75 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.
What needs to be checked for an existing compressor room?
Check the delivery route, floor support, electrical capacity and cooling-air path. Equipment dimensions are not a substitute for service clearance, and hot exhaust air should be directed away from the cooling inlet.
Can the compressor alone provide dry, oil-free process air?
This is a lubricated screw compressor. Air treatment must be selected for the required moisture, particulate and oil limits at the point of use. Specify the receiver, dryer and filters as part of the complete system.
