The PLPC-P-440-EV S/S Coalesce Filter Element can be used for natural gas filtration and oil filtration. The filter element is made of various composite materials processed by special processes and has hydrophilic properties. It can not only filter out mechanical impurities in the medium, but also separate emulsified water from the medium through demulsification and coalescence, and coalesce into larger water droplets, which is conducive to further purifying the medium.

Droplets of oil, water, and other liquids are captured by ultrafine fibers inside the coalescer. These micrometer sized fibers form a tortuous channel for the airflow, forcing solid particles and liquid droplets to be captured by ultrafine fibers through three filtering mechanisms: inertial collision, diffusion interception, and direct interception. The surface tension of the liquid causes small droplets to coalesce into larger droplets, which settle to the bottom of the container due to gravity.
