product description
The coalescing filter element is made of a variety of composite materials processed by special processes and has hydrophilic properties. It can not only filter out mechanical impurities in the medium, but also remove emulsified water from the medium through demulsification and coalescence. Separate and coalesce into larger water droplets to facilitate further purification of the media.

Filtration principle
Droplets of oil, water and other liquids are captured by ultra-fine fibers inside the coalescer. These micron-sized fibers form tortuous channels for the air flow, forcing solid particles and liquid droplets to undergo three processes: inertial collision, diffusion interception and direct interception. Under the action of this filtration mechanism, they are captured by ultrafine fibers. The surface tension of the liquid causes the small droplets to coalesce into larger droplets. Due to gravity, the large droplets settle to the bottom of the container.
The glass fiber coalescing filter element is made of high-density gradient glass fiber. It is designed into an overall monolithic tube structure to reduce damage and leakage. The surface of the filter element is treated with hydrophobic and oleophobic treatments to meet various precision grade requirements.
Polyester fiber coalescing filter element The filter element material is usually made of polyester fiber synthetic material, which has good compatibility with various fluids. The filter element is spirally rolled with a multi-layer structure. Each layer uses fibers with different properties. The expected filtration accuracy can be achieved by controlling the shape, size, thickness, density and other parameters of each layer of fibers.
The coalescing filter element mainly uses surface-treated glass fiber or polyester fiber as the coalescing medium. The structure of the filter material is specially designed to make the filter medium have good coalescing performance. The filtration precision can reach 0.1μm.

Product advantages
The glass fiber coalescing filter element is made of high-density gradient glass fiber, which can efficiently coalesce liquid mist and droplets in the air flow and achieve high filtration accuracy. The structure is stable, there is no medium fiber shedding, and it will not cause pollution to the environment or downstream products. It has good compatibility with various fluids; good environmental protection, 100% synthetic materials, complete combustion without residue.
