1. Product Concept

The CAA28-5 is an advanced-tier, high-efficiency coalescing filter cartridge designed for applications where the highest levels of fluid purity and reliability are non-negotiable. As part of the premium CAA28 series, it incorporates enhanced filtration media and refined engineering to deliver performance that exceeds standard coalescing filters. Operating within a compact 5-inch form factor, it is engineered to achieve ultra-low residual contamination levels, providing exceptional protection for the most sensitive downstream equipment, instruments, and processes in critical industrial environments.

2. Key Features & Advantages

• Superior Filtration Performance

• Utilizes a proprietary, multi-stage composite media designed for maximum coalescing efficiency, typically rated to remove liquid aerosols and solid particles down to ≥0.01 µm.

• Capable of achieving and maintaining extremely low residual oil content, often ≤0.01 ppm or lower, setting a benchmark for air and gas purity.

• Enhanced Media & Construction

• The advanced media structure offers a higher dirt-holding capacity while maintaining a very low initial pressure drop (e.g., 0.02–0.06 bar), optimizing both filtration life and system energy efficiency.

• Built with robust components, including a metal support core and epoxy-sealed end caps, ensuring structural integrity under variable operating conditions.

• Designed for Critical Reliability

• Engineered for consistent performance, with a high degree of moisture and oil aerosol removal efficiency that minimizes the risk of downstream contamination.

• Rated for standard industrial pressures (e.g., up to 16 bar) and a reliable temperature range.

• Standard Compatibility with Premium Output

• Features universal fit dimensions (approx. 69-70 mm OD, 5-inch height) and a standard M30×1.5 male thread interface, allowing it to serve as a direct, drop-in upgrade in housings designed for standard 5-inch coalescing filters, but delivering premium results.

3. Primary Application Areas

• Ultra-High-Purity Compressed Air: Critical uses in semiconductor fabrication (Clean Dry Air, CDA), pharmaceutical manufacturing (process gases), and food & beverage packaging (where the highest air quality is mandated).

• Precision Instrumentation & Analytics: Protection of sensitive gas chromatographs, laser systems, and high-accuracy pneumatic controls.

• Critical Process Gas Systems: Filtration of instrument air, nitrogen, and other gases in petrochemical, biotechnology, and electronics industries where any contamination can compromise product quality or process safety.

• General Industrial Upgrade Applications: Any system where upgrading from a standard filter to a premium model is justified to reduce operational risk, improve product yield, or extend the life of valuable downstream assets.
