Product Name: CA28-9 High-Efficiency Coalescing Filter Element (9-Inch)

1. Product Concept

The CA28-9 is a high-capacity, extended-length coalescing filter cartridge engineered for industrial compressed air and gas systems that demand superior flow handling or extended operational life. Its fundamental design principle leverages a 9-inch (229 mm) length to provide a substantially larger filtration media area compared to standard shorter filters. This enables the element to process higher volumetric flows or capture a greater contaminant load before requiring replacement. It is dedicated to the efficient removal of oil mist, water aerosols, and fine particulate matter, ensuring the delivery of clean, dry fluid to protect sensitive downstream equipment and maintain process integrity in medium to high-flow applications.

2. Key Features & Advantages

• Enhanced Flow Capacity & Service Life

• The 9-inch extended length offers approximately 80% more active media area than a standard 5-inch filter. This allows it to support significantly higher flow rates or, at equivalent flows, greatly extend service intervals, reducing maintenance frequency, downtime, and total cost of ownership.

• High-Efficiency Coalescing Performance

• Incorporates a multi-layered, gradient-density glass fiber or synthetic media pack designed for efficient coalescence, typically rated to remove liquid and solid contaminants down to ≥0.1 µm.

• Consistently maintains low outlet fluid contamination, with residual oil content generally ≤0.1 ppm under standard operating conditions.

• Optimized System Efficiency

• The increased surface area results in lower face velocity for a given flow, which typically translates to a lower initial pressure drop and more stable long-term pressure differential. This design contributes to reduced energy consumption of the compressor or blower over the filter's lifespan.

• Robust Construction & Reliable Compatibility

• Built with a durable metal support core and epoxy-bonded metal end caps to withstand system pulsations and pressure cycles.

• Features a standard industrial connection (commonly a M30×1.5 male thread for 9-inch housings), ensuring secure installation and compatibility with designated extended-length filter housings from various manufacturers.

3. Primary Application Areas

• Main Air Header & Centralized Filtration: Point-of-entry or main distribution line filtration in manufacturing plants, workshops, and large compressed air networks.

• High-Flow Process & Instrument Air Systems: Supply lines for large pneumatic machinery, bulk instrument air systems, and high-volume process gas (e.g., nitrogen, argon) streams.

• Applications Requiring Minimal Maintenance: Remote or hard-to-access installations, critical continuous processes where filter changes are logistically challenging or costly.

• System Upgrades & Retrofit Projects: Used to replace standard-length filters in compatible housings to increase system capacity, improve efficiency, or reduce maintenance burden without major piping modifications.
