7.5kW 8 Bar 4 in 1 PM VSD Air Compressor

Key selling points

I: High-Efficiency Permanent Magnet VSD Technology—Smooth and Quiet Operation
Equipped with a 7.5kW permanent magnet variable speed drive (VSD) motor, featuring a direct-drive structure that eliminates transmission losses. It delivers a stable output of 0.8 MPa with an air displacement of 1.0 m³/min, meeting the continuous air supply demands of light industrial applications. Measured noise levels are a mere 62 ± 3 dB; thanks to an excellent air-cooled temperature control system, the unit remains free from overheating even during prolonged periods of continuous operation.
II: 4-in-1 Integrated Design—Space-Saving and Streamlined Piping
The unit features a fully integrated layout with a built-in air receiver tank and refrigerated air dryer, eliminating the need for external drying equipment. Its compact dimensions make it ideal for use in confined workshops, laboratories, or mobile work environments; simply plug it in and it is ready to use, significantly reducing installation costs.
III: Refrigerated Dryer + Precision Filtration—Pure, Oil-Free, and Water-Free Air Supply
Configured with a 1.6 m³/min refrigerated air dryer for powerful moisture removal, the unit also features a four-stage filtration system with a precision rating of 0.01 ppm. This system thoroughly removes oil contaminants and particulate matter, effectively protecting pneumatic tools and precision instruments.
IV: Comprehensive Factory Testing—Durable and Reliable
Every 7.5kW 8 Bar 4 in 1 PM VSD Air Compressor undergoes a rigorous multi-stage inspection process prior to leaving the factory—including tests for pressure, air tightness, vibration, and temperature rise. The unit is supplied with a 10-liter lubricant capacity, extending maintenance intervals. The Yililai 7.5kW model has demonstrated proven reliability, having successfully operated for over 5,000 hours in various settings such as small-scale processing plants, advertising engraving workshops, and laboratories.

Company Capabilities

Established in 2010, Elily is one of the few domestic brands capable of providing customized high-pressure screw air compressors. The company is equipped with a dedicated test bench for high-pressure air ends and a laboratory for 1.5x pressure burst testing; consequently, every high-pressure model undergoes rigorous durability validation totaling over 1,000 hours.

For our 2-in-1 integrated high-pressure models, we have established specialized assembly and inspection lines. Prior to leaving the factory, every unit undergoes a pressure-holding test at 1.3 times its rated pressure, followed by a 4-hour full-load thermal test. The air receiver tanks are nationally certified pressure vessels, designed to withstand a pressure 1.5 times the maximum operating pressure, and are accompanied by official inspection certificates.

We have successfully provided solutions to over 300 domestic and international clients requiring high-pressure air, serving diverse sectors such as bottle blowing, glass manufacturing, laser applications, and testing. Selling high-pressure compressors involves far more than simply adjusting a pressure switch; we possess a deep understanding of—and meticulous attention to—every critical safety detail involved.
