PECO FG-372 Fiberglass Filter Filters Natural Gas Filter Element

Product Introduction:

coalescer cartridge is a type of filter element made of various composite materials processed by special technology, with hydrophilic properties. Its main function is not only to filter out mechanical impurities in the medium, but also to separate emulsified water from the medium through demulsification and coalescence, and coalesce into larger water droplets, thereby further purifying the medium. The filtration principle of the coalescing filter mainly relies on its internal ultrafine fibers, which form tortuous channels for the airflow, forcing solid particles and liquid droplets to be captured by the ultrafine fibers through three 

filtration 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.

The materials of the coalescing filter usually include glass fiber and polyester fiber. The glass fiber coalescing filter is made of high-density gradient glass fiber and designed as a single piece tube structure. The surface is treated with hydrophobic and oleophobic properties to meet various precision level requirements. The polyester fiber coalescing filter cartridge is made of a multi-layer spiral structure, with each layer using fibers of different properties. The desired filtration accuracy is achieved by controlling the shape, size, thickness, and density of each fiber layer. These filter cartridges mainly use surface treated glass fiber or polyester fiber as the aggregation medium.

Characteristics of coalescer cartridge:

coalescer cartridge mainly include its multi-layer composite material structure, high filtration accuracy, good coalescing effect, pressure resistance, long life and low maintenance cost, as well as a wide range of applications. ‌

Multi layer composite material structure: The coalescer cartridge is made of various composite materials processed by special processes, and has hydrophilic properties. This multi-layer structure design enables the filter element to filter layer by layer, improving filtration efficiency and suitable for purification treatment of various liquid media, including but not limited to industrial water, lubricating oil, hydraulic oil, fuel, etc.

High filtration accuracy: The coalescer cartridge can filter the medium with high precision of 1-25 μ m, effectively removing solid impurities and tiny water droplets from the oil, ensuring its efficient filtration performance.

Good coalescing effect: The coalescer cartridge captures droplets of oil, water, and other liquids through its ultrafine fibers. Through demulsification and coalescing, the emulsified water is separated from the medium and coalesced into larger water droplets, facilitating further purification of the medium.

Pressure resistance performance: The coalescer cartridge is made of high-strength materials and has good pressure resistance performance, ensuring the normal operation of the filter element under high flow and high pressure conditions.

Long lifespan and low maintenance cost: Due to its efficient coalescence and separation mechanism, coalescence filters have a longer service life compared to traditional filters. At the same time, its structural design is easy to clean and replace, reducing maintenance costs and downtime, providing strong support for the continuous production of enterprises.

Wide application range: Agglomeration filters are widely used in many industries, including but not limited to fuel, gasoline, diesel, tar, liquefied petroleum gas, and low viscosity hydraulic and lubricating oil filtration.

In summary, coalescing filter cartridges play an important role in the industrial and fluid processing fields due to their high filtration efficiency, good coalescing effect, pressure resistance, long lifespan, low maintenance cost, and wide range of applications.

Working principle of coalescing filter cartridge:

The working principle of the agglomeration filter is mainly based on the filtration and agglomeration of ultrafine fibers, as well as the utilization of liquid surface tension. ‌

The coalescing filter captures droplets of oil, water, and other liquids through its internal ultrafine fibers. These micrometer sized fibers form tortuous channels for 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, and due to gravity, larger droplets settle to the bottom of the container. This design is particularly suitable for applications that require high-precision filtration, such as the purification treatment of aviation fuel, gasoline, kerosene, diesel and other oil products.

Agglomeration filter cartridges are usually made of multiple layers of composite fiber materials with different densities, which have been specially treated to adsorb and agglomerate tiny water droplets. When the oil flow containing fine water droplets passes through these filters, the small water droplets are adsorbed by the fibers and gradually aggregate into larger water droplets. These larger water droplets are easily separated from the oil under the action of gravity, thus achieving the purpose of dehydration. This technology can not only be used for a long time when physical or chemical damage is not severe, but also greatly reduces operating costs, which is the unique feature of agglomeration separation technology. ‌

In addition, coalescing filter cartridges have shown significant effects in industrial applications, especially in the treatment of emulsion emulsions and dehydration. The excellent performance of the coalescing filter element makes it an efficient oil-water separation solution. By filtering out various small particles, moisture, fibers, and suspended solids in the fuel, the coalescence separator can provide a solution that integrates filtration and dehydration, suitable for various fields including aviation fuel, gasoline, kerosene, diesel, liquefied petroleum gas, low viscosity hydraulic lubricants, turbine oil, etc.
