Custom 15kW High Pressure PM VSD Air Compressor 7.5kW to 75kW

I. High-Pressure Customization Capability (Freely Selectable Range: 10–20 kg/cm²)
Unlike conventional 0.8 MPa models, this series of High-Pressure PM VSD Air Compressors features a design fundamentally engineered to enhance the pressure resistance ratings of both the air-end and the piping system. For the 15 kW model, the air delivery rates at various pressure points are as follows: 0.7 MPa → 2.4 m³/min; 0.8 MPa → 2.3 m³/min; 1.0 MPa → 2.0 m³/min; and 1.3 MPa → 1.7 m³/min. Should requirements extend to 1.6 MPa or even 2.0 MPa, customized solutions can be achieved by adjusting the motor speed in conjunction with the air-end. This series has successfully replaced piston compressors in high-pressure applications—such as bottle blowing—receiving positive feedback regarding pressure stability and significantly reduced energy consumption.
II. High Efficiency and Low Consumption via PM VSD Technology; Energy-Efficient Even Under High-Pressure Conditions
The Custom 15kW High Pressure PM VSD Air Compressor 7.5kW to 75kW is equipped with an IE4-efficiency Permanent Magnet Synchronous Motor, paired with a variable frequency drive (VFD) capable of 0–100% stepless speed regulation. When air demand decreases, the system automatically lowers the operating frequency, thereby eliminating the energy waste associated with the frequent load/unload cycles typical of piston compressors. Real-world data demonstrates that under operating conditions of 1.3 MPa and an air demand of 1.5 m³/min, this unit saves approximately 3 kWh per hour compared to a 7.5 kW piston compressor, resulting in annual electricity cost savings exceeding 6,000 RMB. The typical return-on-investment (ROI) period ranges from 6 to 12 months.

III. Forced Air Cooling + Enlarged Radiator; No Overheating During Continuous High-Pressure Operation
To address the high compression ratios and significant heat generation inherent in high-pressure operating conditions, this series is specifically configured with a plate-fin radiator that is 20% larger than standard models, complemented by a high-efficiency cooling fan. Under real-world test conditions—at an ambient temperature of 35°C and a continuous load of 1.3 MPa—the discharge temperature remained stable within 85°C. The unit comes standard with a temperature protection switch that triggers an automatic alarm and shutdown in the event of overheating. Compared to piston compressors, the screw-type structure demonstrates superior durability and resilience during continuous high-pressure operation, effectively preventing "red cylinder" failures caused by excessive heat.

IV. Silent and Low-Vibration Operation; No Dedicated Soundproof Room Required
The operational noise level is merely 65 dB(A), which is equivalent to the volume of a normal conversation. The screw air-end features a low-noise profile design; the cabinet interior is lined with sound-absorbing cotton, while vibration-damping pads effectively isolate vibration. It can be installed directly alongside the production line—eliminating the need to construct a dedicated compressor room—thereby saving on civil engineering costs. This unit is widely deployed in noise-sensitive production environments, such as glass cutting operations.

V. Comprehensive Factory Inspection: Ensuring High-Pressure Safety
Prior to shipment, every high-pressure model undergoes an airtightness test at 1.3 times its rated pressure, as well as a 4-hour full-load thermal test. The piping system utilizes thickened seamless steel tubing, and all fittings are of a specialized high-pressure grade. Standard safety features include a triple-redundancy protection system comprising a safety valve, a pressure sensor, and a pressure relief valve. The unit comes with a one-year warranty on the complete machine and a three-year warranty on the air-end.

Procurement Considerations

Determining Actual Maximum Pressure
We do not recommend selecting a model with excessive pressure headroom. For every 0.1 MPa increase in pressure, the air displacement volume decreases by approximately 8% at a constant power output. Please provide your precise pressure requirements, and we will assist you in calculating the optimal equipment configuration.
Piping Pressure Rating
The equipment supplied from our factory already meets the required pressure rating standards; however, any user-supplied air receivers, piping, and valves must also meet these same pressure standards. We can also supply matching high-pressure air receivers and provide the corresponding inspection and certification documents.
Cooling Conditions
High-pressure operation generates a significant amount of heat; therefore, please ensure that the installation site is well-ventilated or that a dedicated cooling air duct is provided.
Lubricant Selection
High-pressure models come standard with synthetic oil. This lubricant offers superior oxidation resistance, allowing the oil change interval to be extended to 3,000 hours.

Genuine Customer Feedback

FAQ

1. Can this Custom 15kW High Pressure PM VSD Air Compressor 7.5kW to 75kW reach a pressure of 2.0 MPa?
The standard maximum pressure for our 15 kW model is 1.3 MPa; however, we can upgrade it to 1.6 MPa—or even 2.0 MPa—by replacing the high-pressure air-end and piping system. Note: Upgrading the pressure capacity will result in a reduction in air output volume. Please consult our sales team and provide your specific air consumption requirements for precise figures.

2. Are high-pressure air compressors more prone to breakdowns?
At Yililai, our custom high-pressure models feature a reinforced design across all components—from the air-end, bearings, and piping to the cooling system. We have been active in the high-pressure compressor market for four years, maintaining a repair rate of less than 2%. We utilize SKF bearings and imported seals for our core components; provided you follow the standard maintenance guidelines outlined in the manual, you can expect worry-free operation for at least three years.

3. Is the noise level really just 65 dB?
Based on actual measurements taken at full load (1.3 MPa) at a distance of one meter from the unit, the noise level is approximately 65–67 dB(A). This is significantly quieter than piston-type compressors; there is no need for a dedicated soundproof room—the unit can simply be placed in a corner of your workshop.

4. Do you support different voltages and frequencies?
Yes, we do. We can customize the voltage (e.g., 220V, 380V, 400V, 415V, 440V, etc.) and frequency (50 Hz / 60 Hz) to meet the specific requirements of your export destination country or region. Please specify your requirements when placing your order.
