The Atlas Copco ZT22 oil-free air-cooled screw compressor airend is the heart of the entire compression system, delivering stable and clean compressed air without any oil contamination. This model (P/N 1616711781 / 1616710781) is engineered for precision performance, using advanced materials and manufacturing processes to meet the strict air quality demands of industries like electronics, food processing, pharmaceuticals, and textile manufacturing.
Unlike oil-injected types, the ZT22 airend uses dry-running screw technology, where the rotors do not require lubrication. This ensures complete air purity, making it ideal for applications that cannot tolerate even minimal oil presence.
Design & Material Features
Each airend is carefully engineered with asymmetric profile rotors that reduce internal leakage and minimize energy loss. The rotors are machined from high-strength stainless alloy steel, offering excellent wear resistance and stability even at continuous high-speed operation.
The housing and bearing seats are made from precision-cast high-grade aluminum alloy, ensuring lightweight strength and optimal heat dissipation. Surface treatments and anti-corrosion coatings are applied to enhance protection against oxidation and moisture, especially in air-cooled systems that operate under variable ambient temperatures.
Oil-Free Compression Technology
The ZT22 airend adopts a two-stage dry screw compression system that guarantees ISO 8573-1 Class 0 certified air purity. Each stage is separated by an intercooling process to reduce the discharge temperature and increase volumetric efficiency.
- First stage: Draws and pre-compresses ambient air under controlled temperature.
- Intercooling stage: Dissipates heat efficiently through an air-cooled circuit.
- Second stage: Achieves the final pressure level while maintaining 100% oil-free integrity.
This design not only extends the lifespan of seals and bearings but also significantly reduces power consumption compared to traditional single-stage systems.
Performance Advantages
- High Volumetric Efficiency: Optimized rotor profile and precision clearances minimize internal leakage.
- Low Noise & Vibration: Rotor balancing and advanced bearing design ensure smooth, quiet operation.
- Energy Saving: Reduced mechanical friction and improved heat transfer enhance overall system efficiency.
- Easy Maintenance: Modular structure allows for direct replacement of the airend without major disassembly.
- Clean & Reliable Output: Fully oil-free air stream meets stringent industrial standards for critical applications.
Quality Control & Testing
Every replacement airend undergoes strict dynamic balancing, pressure, and temperature tests before delivery. Dimensional tolerances are verified with precision CMM equipment, and rotor alignment is inspected to ensure consistent performance and long-term durability.
Our factory employs ISO-certified production systems to guarantee uniform quality across all batches. Each airend comes with comprehensive traceability and serial number identification.
