An oil-free scroll air compressor is a positive displacement air compressor that uses scroll compression technology and requires no lubricating oil for gas compression. Its core components consist of a fixed static scroll and a rotating orbiting scroll. The meshing motion of these two scrolls allows gas to be drawn in, compressed, and discharged, without any oil contamination.

Features and Advantages
100% oil-free
No lubricant enters the compression chamber, and the output air meets ISO 8573-1 Class 0 oil-free standards, meeting high-purity requirements in industries such as pharmaceuticals, food, and electronics.
Highly efficient and energy-efficient
The scroll structure operates smoothly, minimizing mechanical losses and saving approximately 30% energy compared to piston compressors, making it suitable for intermittent or continuous operation.
Low noise and vibration
With no reciprocating parts, noise levels are typically below 60 decibels, making it suitable for quiet environments such as laboratories and hospitals.
Simple maintenance
The oil-free design eliminates consumables such as oil filters and oil separators, requiring only regular air filter replacement and seal inspection.
Compact and lightweight
The simple structure and small size make it easy to install and move.
Applications
Medical
Air supply for ventilators, dental equipment, and surgical instruments.
Food and Beverage
Packaging machinery, fermentation processes, and pneumatic conveying.
Electronics
Chip packaging, PCB cleaning, and precision instruments.
Laboratory
Analytical instruments and pneumatic control.
Other: Photovoltaics, chemical processes, and other applications requiring oil-free air.
FAQS
Q1: Can oil-free scroll compressors replace oil-containing air compressors?
A: They are only suitable for clean applications. High-power requirements (such as large-scale industrial applications) still favor screw compressors.
Q2: What is their lifespan?
A: The core scroll has a lifespan of approximately 40,000 to 80,000 hours, but dust and liquid inhalation must be avoided.
Q3: Is post-processing equipment required?
A: A dryer (such as a refrigerated dryer) is typically required to remove moisture, but an oil removal filter is not required.
Q4: What are the advantages and disadvantages compared to oil-free screw compressors?
A: Scroll compressors are quieter and less expensive, but their flow rate per unit is generally ≤20 m³/min; screw compressors are suitable for higher flow rates.
Q5: How do I determine whether I need an oil-free compressor?
A: If the end equipment or process requires "oil-free air" (such as for FDA certification), then an oil-free compressor is essential.
