1. Product Concept
The DC.7-1422-xx is a precision-engineered coalescing filter cartridge designed for final-stage purification of compressed air and other industrial gas streams. Its core principle is based on coalescence—the process of merging ultrafine, suspended liquid aerosols (oil, water, and process liquids) into larger, heavy droplets that can be easily separated and drained by gravity. This action transforms an invisible contaminant in an air/gas line into a manageable liquid, delivering gas of exceptional purity to protect critical downstream systems and processes.

2. Key Features & Benefits

• High-Efficiency Coalescing Media: Utilizes a multi-layered, graded-density media structure that ensures maximum contaminant removal, achieving extremely low residual oil content (often as low as 0.01 ppm).

• Dual-Stage Filtration: Effectively captures solid particulate in its initial depth filtration layer before the fine-fiber coalescing stage, providing comprehensive protection.

• Optimized Performance & Life: The engineered media pack offers high dirt-holding capacity and low pressure drop, ensuring longer service intervals, reduced energy consumption, and lower total cost of ownership.

• Robust & Reliable Construction: Features a durable center tube and stable end caps to prevent media migration and bypass, guaranteeing consistent performance under variable operating conditions.

• Standardized Design (xx variant): The "xx" denotes specific size/material options, allowing for easy selection and direct replacement in compatible filter housings, simplifying maintenance and inventory.

3. Primary Application Fields
This cartridge is critical in industries where clean, dry, and oil-free gas is non-negotiable for product quality, process safety, and equipment protection.

• General Manufacturing: Protecting pneumatic tools, cylinders, valves, and control systems from liquid contamination.

• Process Industries: Providing instrument-quality air for chemical, petrochemical, and pharmaceutical manufacturing.

• Food & Beverage: Ensuring oil-free compressed air for direct and indirect contact applications (e.g., packaging, mixing).

• Surface Treatment & Painting: Eliminating oil and water aerosols that cause defects in paint spray and coating processes.

• Energy Sector: Conditioning compressed natural gas (CNG) and other process gases.
