The oil-free screw airend is the core compression unit in an oil-free air compressor system. Models 1616585180 and 1616585181 are designed for Atlas Copco oil-free screw compressors, where absolute air purity and mechanical precision are critical.
Unlike oil-injected airends, this oil-free design compresses air without any oil involvement in the compression chamber, making it suitable for applications that demand contamination-free compressed air.
Oil-Free Compression Principle
In oil-free screw compressors, the airend relies on precisely machined rotors and advanced surface treatments rather than oil for sealing and cooling. The rotors operate with extremely tight tolerances, allowing efficient compression while preventing metal-to-metal contact.
This design ensures that the compressed air remains completely oil-free, meeting strict air quality standards required in sensitive industrial environments.
Structural Design & Rotor Technology
The airend housing and internal rotors are engineered for dimensional stability and long-term accuracy. Rotor profiles are optimized to maintain consistent compression ratios, reduce internal leakage, and minimize energy loss during operation.
Special coatings on the rotor surfaces enhance wear resistance and thermal stability, helping the airend maintain efficiency even under continuous operation or fluctuating load conditions.
Thermal Stability & Operating Reliability
Oil-free compression generates higher internal temperatures compared to oil-injected systems. This airend is designed with optimized internal airflow paths and heat management characteristics to ensure stable thermal behavior.
By maintaining consistent clearances across temperature ranges, the airend delivers reliable performance without compromising efficiency or air quality.

Air Quality & System Performance
Because no oil is used in the compression process, the airend supports the delivery of Class 0 oil-free compressed air when used within a properly configured system. This protects downstream equipment, reduces maintenance requirements, and ensures compliance with strict industry standards.
Stable airflow and pressure output also help improve overall system efficiency and reduce load fluctuations on the drive motor.
Maintenance & Service Considerations
Although oil-free airends eliminate oil-related maintenance, regular inspection of bearings, seals, and cooling systems remains essential. Proper installation and alignment help ensure long service life and maintain compression efficiency over time.
Replacing a worn or damaged airend with a correctly specified unit restores system efficiency and protects the compressor from secondary mechanical stress.
Why the Airend Matters in Oil-Free Systems
In an oil-free compressor, the airend determines not only performance but also air purity and system longevity. Choosing a precisely engineered airend such as 1616585180 / 1616585181 ensures stable compression, consistent air quality, and dependable operation for demanding industrial environments.
