1. Product Concept

The DC.4-842-xx series is a modular line of high-efficiency coalescing filter cartridges designed for liquid and solid contaminant removal in compressed air and gas systems. Operating on the principle of coalescent filtration, the cartridge captures sub-micron oil and water aerosols along with fine particulate matter from the air stream. Through its multi-stage depth media, these suspended aerosols are merged into larger, heavy droplets that drain away by gravity, effectively preventing liquid carryover. The "xx" designation indicates specific performance variants within the series, allowing tailored selection based on efficiency, flow rate, or connection requirements.

2. Key Features & Advantages

• High-Efficiency Multi-Stage Media: Utilizes a graded-density matrix of fine glass fibers and synthetic layers to ensure superior aerosol capture, typically achieving 99.99+% efficiency at 0.1 micron.

• Low Pressure Drop & High Dirt-Holding Capacity: The optimized media structure maximizes contaminant loading while maintaining minimal restriction to airflow, reducing energy costs and extending service intervals.

• Robust, Leak-Free Construction: Features durable inner and outer support cores, along with precision-molded end caps and reliable elastomeric seals (e.g., Buna-N O-rings), ensuring structural integrity and preventing bypass.

• Versatile Compatibility: Designed for broad operational compatibility with mineral and synthetic lubricants, and suitable for standard industrial temperature and pressure ranges.

• Easy, Safe Replacement: Engineered as a one-piece, drop-in cartridge for quick maintenance without risk of media contamination or handling exposure, minimizing downtime.

3. Primary Application Fields

• General Industrial Compressed Air Systems: Protecting downstream equipment such as pneumatic tools, cylinders, valves, and actuators from liquid and solid contamination.

• Critical Point-of-Use Applications: Ensuring ultra-clean air for precision instrumentation, painting systems, laser cutting, food and beverage processing, and pharmaceutical manufacturing.

• Pre-Filtration for Sensitive Equipment: Serving as an essential pre-filter for desiccant dryers, membrane dryers, and sterile filters to extend their lifespan and maintain performance.

• OEM and Packaged Systems: Integrated by original equipment manufacturers into compressor packages, air treatment skids, and modular filtration units for reliable, off-the-shelf performance.
