The oil-free scroll compressor is a high-performance air compression device based on non-contact scroll compression technology. Its core consists of a pair of intermeshing scrolls: a fixed, stationary scroll and an eccentrically rotating orbiting scroll. The orbital motion of the orbiting scroll smoothly pushes gas toward the center of a gradually shrinking, crescent-shaped compression chamber, achieving continuous, pulsation-free compression. The entire compression process is completely sealed, with zero contact between gas and mechanical transmission components, eliminating oil contamination at the source. This delivers 100% pure, oil-free compressed air, meeting ISO 8573-1 Class 0 international oil-free certification.
Due to its streamlined structure and minimal moving parts, this device offers extremely low mechanical friction, operating noise levels below 75 decibels, and boasts 20%–40% higher energy efficiency than conventional compressors. It also maintains excellent stability even under long-term, high-load conditions. Its oil-free design eliminates ongoing lubricant costs and the expense of replacing accessories like oil filters and oil-gas separators, reducing annual maintenance costs by over 30%. Its overall energy consumption and operating expenses are significantly better than those of traditional oil-containing air compressors.
Oil-free scroll air compressors have become essential infrastructure in key sectors requiring extremely high air quality:
In the food and beverage industry, they are used in filling, packaging, and preform purging processes, preventing product spoilage due to oil contamination while significantly reducing energy consumption. For example, one large beverage company saw a 30% reduction in gas and electricity consumption after implementing oil-free scroll air compressors.
In the pharmaceutical and medical fields, they provide sterile, oil-free air for ventilators, pharmaceutical manufacturing, and laboratory pneumatic equipment, meeting GMP and pharmacopoeia standards and ensuring patient safety and a healthy pharmaceutical production environment.
In electronics manufacturing, particularly semiconductor, chip packaging, and PCB manufacturing, they ensure the compressed air is free of residual oil molecules, preventing micro-contamination that can reduce product yields. This has resulted in one electronics company saving over 250,000 yuan annually in electricity and maintenance costs.
They also play a vital role in critical pneumatic equipment in the energy, chemical, and textile sectors, such as power plant desulfurization instrument air, precision spray painting, and high-end loom drives, improving system reliability and product quality.
Oil-free scroll air compressors not only ensure zero gas pollution with leading technology, but also become core power equipment supporting advanced manufacturing, energy conservation and emission reduction, and industrial upgrading with their high efficiency, energy saving, low maintenance costs, and high stability.
