CDD Oil-Free Double-Stage Air Ends

The CDD oil-free double-stage air ends are designed to meet the highest standards of compressed air purity and operational efficiency. Engineered for applications where air quality is critical, these air ends combine advanced compression technology with robust construction to deliver oil-free performance without compromising reliability. Designed for OEM integration, the CDD series supports consistent output, optimized energy consumption, and long-term operational stability across a wide range of industries.


Oil-Free Compression for Critical Applications

The CDD Series is specifically developed for industries that require contamination-free compressed air, such as food processing, pharmaceuticals, electronics, and healthcare. Its oil-free design eliminates the risk of oil carryover, ensuring the integrity of end products and processes.

This clean-air capability not only meets strict regulatory requirements but also reduces the need for additional filtration, simplifying system design and lowering maintenance complexity.

Double-Stage Technology for Superior Efficiency

At the core of the CDD Series is a double-stage compression process designed to maximize overall efficiency. By splitting the compression into two stages, the system reduces thermal stress and enhances energy performance compared to traditional single-stage solutions.

This design leads to lower discharge temperatures, higher volumetric efficiency, and decreased power consumption, making it especially suitable for continuous-duty applications where reliability, performance, and cost efficiency are critical.

Engineered for Continuous Reliability

Reliability is fundamental in demanding industrial environments, and the CDD air ends are built to perform under continuous operation. High-quality materials, precision manufacturing, and optimized bearing configurations ensure smooth operation and reduced mechanical wear.

This durable design extends service life and minimizes downtime, providing users with consistent performance and lower lifecycle costs.

Seamless OEM Integration and Design Flexibility

The CDD Series is developed with OEM requirements in mind, offering flexible integration into customized compressor systems. Its modular design allows manufacturers to adapt configurations based on application needs, ensuring compatibility with different system layouts.

This adaptability enables the development of advanced compressor solutions that meet both technical specifications and market demands while maintaining compact and efficient system design.

Optimized Thermal Management and Performance Stability

Double-stage compression inherently improves thermal control, which is essential for maintaining efficiency and protecting internal components. The CDD Series benefits from optimized airflow and cooling characteristics, ensuring stable operation even under high load conditions.

This stability contributes to consistent compressed air delivery and enhances overall system performance, especially in applications requiring uninterrupted operation.

With decades of experience in compressor design, we've mastered the art of delivering top-notch oil-free screw compressor air ends. Our integrated solution features the compressor stage directly flanged onto a gearbox, complete with essential components like the oil tank, oil pump, and oil filter. Plus, our unique Ultracoat rotor coating ensures higher efficiency and corrosion protection. 
Our CD.S single-stage oil-free screw compressor blocks are perfect for low pressure applications like pneumatic conveying, jet starting, N2 generation, and bulk tanker ship unloading. 
For high-pressure demands, we offer the CD.D double-stage air ends, which are flanged onto the gearbox alongside the low-pressure stage. Rotors operate smoothly on anti-friction bearings, running freely without contact in demanding applications such as chemical, automotive, pharmaceutical, and food and beverage industries. 
With over 60 years of market experience in oil-free compressor units, trust us to meet your needs with expertise and excellence.
