MaxReliability Series Oil-Free Scroll Compressor for Industrial Use

The Oil-free Scroll Air Compressor is a revolutionary device in the field of air compression. It is designed with a unique scroll mechanism, where two spiral-shaped scrolls, one fixed and the other orbiting, work in harmony to compress air. This design eliminates the need for oil in the compression process, ensuring 100% oil-free air output.
This compressor offers several outstanding advantages. Firstly, the oil-free operation makes it suitable for applications where air purity is crucial, such as in the food, medical, and electronics industries. It prevents any oil contamination, which could otherwise affect product quality or manufacturing processes. Secondly, its simple and smooth structure leads to lower noise levels during operation, creating a more comfortable working environment. Additionally, with fewer moving parts compared to traditional compressors, it has a higher reliability and a longer service life, reducing maintenance costs over time. Overall, the Oil-free Scroll Air Compressor is an ideal choice for industries demanding clean, quiet, and reliable air compression solutions.

Product Overview


Engineered for quiet, high-purity environments where noise and contamination are critical concerns, our Oil free Scroll Air Compressor revolutionizes compressed air generation through orbiting scroll technology. This innovative design replaces traditional pistons or vanes with two interlocking scrolls—one fixed and one orbiting—to create compression chambers, eliminating metal-to-metal contact and producing Class 0 oil-free air (ISO 8573-1:2010) without lubricants.


The contactless compression process reduces wear, noise, and maintenance needs, making it ideal for sensitive settings such as hospitals, research labs, and electronics cleanrooms. Its compact footprint and ultra-quiet operation (as low as 53 dB) allow seamless integration into space-constrained environments, while its high reliability ensures uninterrupted service for critical applications.


Product Specifications


Pressure Range: Maintains stable output at 8–10 bar (116–145 psi) with ±0.1 bar precision, ensuring consistent performance for sensitive equipment.

Flow Rate: Offers 0.3–1.5 m³/min (10.6–53 CFM) across compact models like the SFR 2-12 (2.2kW) and SFR 15-10 (15kW), suitable for small to medium-scale operations.

Motor: Equipped with 2.2–15 kW motors featuring IP55 protection (resistant to dust and water jets) and IE4 efficiency, balancing power and energy savings.

Noise Level: Achieves ≤53 dB in medical-grade models—quieter than a normal conversation—making it suitable for noise-sensitive environments like hospitals and offices.

Footprint: Requires ≤0.5 m² of floor space, with a vertical design that maximizes space efficiency in crowded labs or clinics.



Ultra-Quiet Operation: The orbit-driven scroll design eliminates valve noise and reduces mechanical vibrations, creating a peaceful environment ideal for hospitals, dental clinics, and research facilities.

Low Maintenance: With no wearing parts like pistons, valves, or vanes, the compressor requires only annual bearing lubrication and filter changes, with extended 10,000-hour service intervals that minimize downtime.

High Reliability: The contactless compression mechanism reduces component wear by 50% compared to piston compressors, ensuring consistent performance and reducing the risk of unexpected breakdowns.

Energy Efficiency: The permanent magnet (PM) motor achieves 94%+ efficiency at full load and maintains high efficiency even at partial loads, lowering energy costs for continuous-operation facilities.

Class 0 Air Quality: Integral 5-stage filtration (pre-filter, main filter, activated carbon, ultra-fine filter, and sterile filter) ensures ≤0.01 μm particle removal and zero oil content, meeting the strictest purity standards.



Medical Facilities: Powers ventilators, anaesthesia machines, and medical suction systems with sterile air, ensuring patient safety and compliance with healthcare regulations like ISO 13485.

Research Labs: Provides contamination-free air for gas chromatography, mass spectrometers, and cell culture incubators, preventing sample contamination that could invalidate 实验 results.

Dental Clinics: Supports dental chairs, air-driven handpieces, and suction units with quiet, clean air, enhancing patient comfort and reducing clinic noise pollution.

Optical Manufacturing: Delivers dust-free air for lens coating processes, fiber optic assembly, and semiconductor lithography, ensuring precision in delicate optical components.
