Depends on configuration
The LGGPM-30 brings two-stage permanent magnet variable-speed compression to installations with modest airflow requirements and limited equipment space. Air delivery is 4.1 m³/min at 0.8 MPa, with a G1¼ outlet and a unit size of 1476 × 1026 × 1430 mm.
Its cabinet dimensions and threaded outlet make it straightforward to assess a new local air station or the replacement of a smaller compressor. Compare simultaneous tool demand with output at the required pressure, then allow space for storage and air treatment.
1. 22 kW capacity for local air supply
The LGGPM-30 delivers 4.1 m³/min at 0.8 MPa with a 22 kW motor. This duty point suits evaluation of a local compressor station serving equipment with matching air consumption.
2. Two-stage compression in a smaller package
Air is compressed in two successive stages with oil-mist cooling between them. Dividing the pressure rise helps manage the compression process within the compact machine.
3. Direct drive without belt adjustment
The permanent magnet motor drives the compression assembly directly. This removes belt tensioning from the drive maintenance routine, while variable-frequency control adjusts speed as air demand changes.
4. Variable-speed centrifugal fan cooling
The 22 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. Compact cabinet for space planning
The unit measures 1476 × 1026 × 1430 mm and weighs 720 kg. These figures support delivery-route and room-layout checks; allow additional space for service and cooling airflow.
6. G1¼ outlet with pressure-specific performance
The G1¼ air outlet connects the compressor to the air system. Delivery is 4.2 m³/min at 0.7 MPa and 3.5 m³/min at 1.0 MPa, allowing selection at the pressure the process needs.
7. Touch-screen access to operating information
The local touch-screen controller brings operating status and control functions to the front of the compressor, supporting routine checks in a small air station.

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 dedicated production cell, workshop air network or smaller plant utility system, provide average and peak consumption, working hours and pressure losses to the point of use. Use 4.1 m³/min for the 0.8 MPa duty point.
Electrical and cooling provision: Check the 22 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 1476 × 1026 × 1430 mm cabinet, 720 kg unit weight and G1¼ 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-30 provide at different pressures?
Air delivery is 4.2 m³/min at 0.7 MPa, 4.1 m³/min at 0.8 MPa, 3.5 m³/min at 1.0 MPa and 3.2 m³/min at 1.2 MPa. Specify the pressure required by the application when selecting the configuration.
What cooling arrangement does this 22 kW model use?
The LGGPM-30 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 compact cabinet include an air receiver and dryer?
The stated dimensions describe the compressor cabinet. Receiver, dryer and filter requirements depend on the application and should be identified in the quotation; cabinet size alone does not define the complete air-system footprint.
What should I provide for a workshop installation?
Provide the required pressure, the air consumption of tools used together, the operating schedule and the available power supply. Include the intended location and air-quality requirements so that storage, treatment and ventilation can be reviewed.
07 Request an LGGPM-30 Quotation
Request an LGGPM-30 quotation with your required pressure, average and peak air demand, operating hours, available power supply, quantity and destination.
Include the tool list and available floor space so that the compressor, receiver and treatment equipment can be assessed together.
