High Pressure Fixed Speed Air Compressor 7.5kW to 75kW

Elily’s High Pressure Fixed Speed Air Compressor 7.5kW to 75kW—customizable for pressures of 10–20 bar. Featuring stable and reliable fixed-speed direct-drive operation, they are the ideal choice for worry-free, continuous high-pressure performance.

Customizable High-Pressure Capabilities

Unlike standard 8-bar (0.8 MPa) models, this Elily’s High Pressure Fixed Speed Air Compressor 7.5kW to 75kW features a design reinforced from the ground up to handle higher pressure ratings for both the air end and the piping system. All models offer customizable pressure settings within the 10–20 bar (1.0–2.0 MPa) range and undergo airtightness testing at 1.3 times the rated pressure before leaving the factory. Users can lock in the specific operating pressure required for their processes, eliminating the need for post-installation pressure adjustments. Operating at a fixed speed, these units deliver stable, fluctuation-free high-pressure output—making them ideal for applications requiring constant pressure and steady air demand (such as bottle blowing and glass cutting).

Stable, Reliable Fixed-Speed Motor

Equipped with a fixed-speed industrial motor (Efficiency Class 2 or higher, IP54 protection, Class F insulation), the unit runs on a standard 380V/50Hz power supply and utilizes a direct-drive configuration. The simple motor design—free from sensitive variable-frequency drive (VFD) electronics—ensures superior adaptability in harsh environments characterized by high temperatures, dust, or humidity.

Forced Air Cooling & Oversized Radiator

High-pressure operation entails high compression ratios and significant heat generation. For these custom high-pressure models, Yililai has incorporated a plate-fin radiator that is 25% larger than standard, paired with a high-efficiency cooling fan. Actual testing confirms that under an ambient temperature of 38°C and a continuous load of 16 bar (1.6 MPa), the discharge temperature remains stable below 88°C. A standard temperature protection switch triggers an automatic alarm and shutdown in the event of overheating, effectively preventing motor burnout. Unlike piston compressors—which are prone to overheating issues (often referred to as "red cylinder" syndrome)—the rotary screw structure is inherently better suited for continuous high-pressure operation, while fixed-speed operation avoids the additional thermal stress caused by frequent speed changes.

Comprehensive Safety Protection

Every custom high-pressure unit undergoes a pressure-retention test (at 1.3 times rated pressure) and a four-hour full-load thermal test before shipment. The system utilizes thickened seamless steel piping and high-pressure-grade fittings. Safety is ensured through a triple-layer protection system combining mechanical and electronic components: a safety valve, a pressure sensor, and a pressure relief valve. A microcomputer controller monitors pressure, temperature, and current in real-time, automatically triggering an alarm and shutdown if any abnormalities occur. Comprehensive power range coverage: select the ideal model from 7.5 kW to 75 kW.

We offer eight power ratings—7.5 kW, 15 kW, 22 kW, 30 kW, 37 kW, 45 kW, 55 kW, and 75 kW—with air delivery capacities ranging from 1.0 m³/min to 13.0 m³/min, depending on the required pressure. You can find a model that precisely matches your needs, ensuring flexible selection and avoiding energy waste caused by oversizing.
