Key Features and Working Principle

1.  Core Function: Classified as a dry gas particulate filtration element, it is specifically designed to remove solid impurities (such as dust, rust, grit, and weld slag) from natural gas or air streams, thereby protecting downstream equipment such as compressors, flow meters, and valves.

2.  Filtration Mechanism: Employs depth filtration and direct interception technologies. Gas enters from the exterior of the filter element and passes through the pleated polyester fiber media; solid particles are captured by the fibers, while clean gas exits through the central core.

3.  Design Advantages:

-   High Surface Area: The pleated design provides a larger filtration area within a limited space, resulting in lower pressure drop and extended service life.

-   Corrosion Resistance: Both the metal end caps and the core/cage undergo anti-corrosion treatment, ensuring suitability for harsh operating conditions. -   High Compatibility: Compatible with PECO brand 70H and 70V series filter housings, or adaptable to functionally equivalent housings from competing brands.

Key Application Areas

-   Natural Gas Production & Gathering: Removes sand particles and pipeline scale from produced gas at wellheads and gathering stations.

-   Natural Gas Processing & Liquefaction: Performs pre-filtration prior to entry into dehydration and acid gas removal units.

-   Power Generation Industry: Filters inlet air or fuel gas for gas turbines to prevent blade erosion.

-   Industrial Compressed Air Systems: Serves as a high-efficiency dust removal filter.
