The Atlas Copco ATSL-165E scroll compressor airend represents a new generation of oil-free air compression technology. Unlike conventional rotary screw or piston compressors, this scroll head operates without lubrication in the compression chamber, providing 100% oil-free, contaminant-free air suitable for the most demanding clean-air applications.
This air end is widely used in Atlas Copco oil-free scroll air compressor series, where high reliability, low noise, and consistent air purity are critical. It is engineered with a compact form factor, advanced scroll geometry, and precision-matched components to deliver continuous, pulsation-free compressed air at stable pressure levels.
Design and Construction
The ATSL-165E scroll air end is constructed with dual interleaved spiral scrolls, one fixed and one orbiting. The moving scroll compresses air progressively toward the center, resulting in a smooth, continuous flow of compressed air with minimal pulsation and vibration.
Key material and manufacturing features include:
- High-strength aluminum alloy housing with hard-anodized inner surfaces for excellent corrosion resistance and heat transfer efficiency.
- Precision-ground scroll plates made of wear-resistant alloy steel, ensuring long-term dimensional accuracy and sealing performance.
- Special PTFE-based sealing rings at the scroll edges to minimize internal leakage and maintain stable compression ratios.
- CNC machining with micron-level tolerances guarantees perfect meshing of scroll spirals, optimizing volumetric efficiency.
- Integrated cooling channels within the housing to dissipate heat evenly during long operation periods.
Every ATSL-165E unit undergoes a dynamic balance calibration to ensure quiet running, typically producing less than 60 dB(A)—ideal for laboratory and indoor industrial environments.
Working Principle
In a scroll compressor, one scroll remains stationary while the other orbits around it. Air enters through the suction port at the outer edge and becomes trapped in crescent-shaped pockets. As the orbiting scroll moves, these pockets gradually reduce in size, compressing the air toward the center outlet.
Because this process occurs continuously and without valves, it offers steady, vibration-free compression, eliminating the pulsation commonly found in piston compressors. Moreover, since the compression chamber contains no oil, the output air meets ISO Class 0 oil-free standards—ideal for applications where purity and precision are non-negotiable.
Performance and Advantages
The ATSL-165E air end combines mechanical simplicity with exceptional energy efficiency:
- 100% Oil-Free Air Output: No lubricants inside the compression chamber, ensuring contamination-free compressed air for sensitive operations.
- Low Noise and Vibration: Orbiting motion and dynamic balancing reduce sound levels and mechanical wear.
- High Energy Efficiency: The progressive compression process minimizes internal leakage and energy loss.
- Compact and Lightweight Design: Ideal for integrated and portable air systems, saving installation space.
- Thermal Stability: Optimized cooling pathways prevent overheating even under continuous duty cycles.
- Low Maintenance Requirements: Fewer moving parts and no oil management system reduce service frequency and costs.
Applications
The Atlas Copco ATSL-165E scroll head is used in a wide range of precision industries where air purity is crucial:
- Medical and Dental Equipment: For clean air supply in ventilators, sterilizers, and dental tools.
- Electronics Manufacturing: Prevents contamination in semiconductor and PCB assembly.
- Laboratory and Research: Supports controlled environments with particle- and oil-free compressed air.
- Food & Beverage Processing: Ensures compliance with hygiene and safety standards.
- Optical and Instrument Calibration: Provides stable air pressure for sensitive instruments and metrology equipment.
Its oil-free and vibration-free operation also makes it suitable for indoor installation close to work areas.
