PCHG-318 High Performance Coalescing Filter Element for Fuel and Gas Processing System
Introduction:Oil & Gas Filters is a necessary separation and purification equipment element for natural gas gathering and transportation pipelines and gas gathering stations, compressor stations, sub-transportation stations, pigging stations, terminal stations and various application fields. It can effectively filter the dirt in the pipeline. And the fragments of the pipe wall peeling off, to ensure the safe operation of gas transmission and gas equipment, and to meet the quality requirements of pipeline transportation and users.

Product parameter:
Series NGGC cartridges provide effective removal of small aerosol mist and liquid droplets from natural gas streams. Fibers of various denier are weighed, blended and thermally bonded, then formed into a compressed filter media sheet. Multiple recipe layers of PEM are then used in the LEFILTER process to manufacture the unique, advanced depth coalescer cartridge.
Saturated Depth Coalescing gas coalescer cartridges work on a principal referred to as Saturated Depth Coalesing. This allows liquid droplets to collect and saturate the pores within the media depth then grow to their fullest potential. The droplets then drain with gravity when they reach a certain size. These liquid droplets often take with them solid contaminant particles, as well, causing a “self-cleaning” effect within the depth media matrix. This principal works very differently than pleated coalescers which use a tight, treated glass media in order to screen/stop small aerosol liquid droplets then shed them off quickly.
Through thermal bonding, spiral layers of engineered filtration media are applied to conform and overlap each previous layer forming a conical helix pattern. This filter structure results in a gradient density pattern that provides an extraordinary flow path in radial, axial and helical directions. This tortuous flow path yields high contaminant loading, structural strength, maximum efficiency, and an overall outstanding filtration performance.
