Depends on configuration
The LGGPM-300 is a 220 kW two-stage PM VSD compressor for projects requiring a high-volume supply through a DN100 connection. Air delivery is 47.0 m³/min at 0.8 MPa, with a DN100 outlet and a unit size of 3776 × 2126 × 2523 mm.
The enclosure and handling weight call for early coordination of delivery access, floor support and ventilation. Assess the selected pressure point together with treatment capacity and distribution losses before finalizing the station layout.
1. 220 kW supply for high-volume central air
The LGGPM-300 delivers 47.0 m³/min at 0.8 MPa with a 220 kW motor. Use the pressure-specific flow to size the station and its downstream treatment equipment.
2. Two-stage compression with interstage cooling
Air is raised to an intermediate pressure before second-stage compression. Oil-mist cooling between stages supports temperature management within the compression assembly.
3. Direct transmission with demand-responsive VSD
A permanent magnet motor and variable-frequency drive regulate compressor speed as demand varies. Direct drive transfers power to the airend without a belt transmission stage.
4. Variable-speed axial fan cooling
The 220 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. Project-ready dimensions and handling data
The unit measures 3776 × 2126 × 2523 mm and weighs 5980 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 48.6 m³/min at 0.7 MPa and 41.9 m³/min at 1.0 MPa, allowing selection at the pressure the process needs.
7. Oil filtration and separation within the package
The lubricating circuit includes oil filtration and oil-air separation. Service planning should allow access to the filter, separator and coolers alongside the specified oil quantity.

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-volume central-air project with DN100 pipework, provide average and peak consumption, working hours and pressure losses to the point of use. Use 47.0 m³/min for the 0.8 MPa duty point.
Electrical and cooling provision: Check the 220 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, 5980 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-300 provide at different pressures?
Air delivery is 48.6 m³/min at 0.7 MPa, 47.0 m³/min at 0.8 MPa, 41.9 m³/min at 1.0 MPa and 38.0 m³/min at 1.2 MPa. Specify the pressure required by the application when selecting the configuration.
What cooling arrangement does this 220 kW model use?
The LGGPM-300 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 should be arranged before equipment delivery?
Check the complete access route, unloading position, floor support and lifting plan against the unit dimensions and weight. Obtain the installation and handling instructions for the selected configuration before delivery.
How should the dryer and filters be selected?
Use the required air quality and the selected pressure-specific flow, with appropriate allowance for site conditions and the treatment equipment's own rating criteria. Review pressure losses through the complete downstream system.
