7.5kW 8 Bar 4 in 1 PM VSD Air Compressor

Key selling points

I: High-Efficiency Permanent Magnet VSD Technology — Smooth & Low-Noise Operation

Powered by a 7.5kW permanent magnet VSD motor with direct-drive construction to cut transmission energy loss. It provides stable 0.8MPa pressure and 1.0 m³/min airflow, satisfying continuous air demand for light industrial scenarios.

The running noise is only 62 ± 3 dB. Supported by premium air-cooled thermal control, the unit avoids overheating even under long-term continuous operation.

II: 4-in-1 Integrated Design — Space Saving & Simplified Piping

This all-in-one unit comes with built-in air receiver tank and refrigerated dryer, requiring no external air treatment equipment. Compact size makes it perfect for narrow workshops, laboratories and mobile working sites. Realize plug-and-play operation and greatly lower installation expenses.

III: Refrigerated Dryer & Precision Filtration — Clean, Oil-Free & Dry Compressed Air

Equipped with a 1.6 m³/min refrigerated dryer for efficient moisture removal. Matched with a 4-stage filtration system up to 0.01 ppm precision, it fully eliminates oil pollutants and solid particles to safeguard pneumatic tools and precision instruments.

IV: Strict Factory Testing — Outstanding Durability & Reliability

Each 7.5kW 8 Bar 4-in-1 PM VSD air compressor passes multi-item factory tests covering pressure holding, air tightness, vibration and temperature rise before shipment.

It adopts a 10L large-capacity lubricant tank to extend maintenance cycles. This model has accumulated more than 5,000 hours of stable operation in small processing factories, advertising engraving workshops and laboratories, fully verifying its reliable performance.

Product Specifications:

Company Capabilities

Founded in 2010, Elily is among the limited domestic brands that can deliver customized high-pressure screw air compressors. We own exclusive test benches for high-pressure airends and a laboratory supporting 1.5-times pressure burst testing. All high-pressure models pass strict durability verification tests running more than 1,000 hours.

Specialized assembly and inspection production lines are available for our 2-in-1 integrated high-pressure compressor series. Every unit undergoes a pressure holding test at 1.3 times the rated pressure and a 4-hour full-load temperature rise test before shipment. Our air receiver tanks are nationally certified pressure vessels, engineered to endure 1.5 times maximum working pressure, with official inspection documents supplied.

We have delivered tailored compressed air solutions to more than 300 domestic and global high-pressure air users, covering bottle blowing, glass production, laser processing, pressure testing and other industries. Tuning the pressure switch is far from sufficient for reliable high-pressure compressor manufacturing. We thoroughly study every working condition and strictly control all critical safety factors for stable and secure operation.
