OVERVIEW

High-Efficiency Coalescing Filter

Element for Fuel & Oil Water Separation

What is a Coalescing Filter Element?

A Coalescing Filter Element is a filter element processed from various composite

materials through special techniques. It is characterized by hydrophilic properties

and excellent coalescing performance. Filtration Precision: Can reach up to 0.1 um.

FUNCTION AND WORKING PRINCIPLE OF COALESCING FILTER ELEMENTS

The main function of a coalescing filter element is to achieve deep purification of the medium through two core mechanisms: "filtration" and "separation."

CORE FUNCTIONS

Filter Mechanical Impurities

Capable of filtering out solid particles and other mechanical impurities contained in the medium (such as oil, water, or other liquids).

Separate Water

This is the core function. It separates emulsified water from the medium through the mechanisms of demulsification and coalescence.

Coalesce into Large Droplets and Settle

The separated small water droplets coalesce into larger droplets due to surface tension inside the filter element (e.g., on ultrafine fibers). These large droplets settle to the bottom of the container due to gravity, thus achieving the separation of water from the medium and facilitating further purification.

Brief Description of the Working Principle

Solid particles and liquid mist droplets in the medium are captured by ultrafine fibers under the action of three filtration mechanisms: inertial collision, diffusion interception, and direct interception. Small droplets coalesce and grow larger due to surface tension, and finally settle due to gravity.

APPLICATIONS

Coalescing Filter Elements Are Widely Used In The Purification And Dewatering Of Various Liquid Media

Fuels

Aviation fuel, gasoline, kerosene, diesel, liquefied petroleum gas (LPG), coal tar.

Lubricating Oils

Turbine oil and other low-viscosity hydraulic oils and lubricating oils.

Aromatics

Benzene, toluene, xylene, cumene, polybenzene propene, etc.

Alcohols/Ketones

Cyclohexane, isopropyl alcohol, cyclohexanol, cyclohexanone, etc.

Others

Other hydrocarbon compounds.

BENEFITS

01

Ultra-High Filtration and Purification Precision

Achieves deep medium purification with a maximum filtration precision of 0.1um, effectively removing solid particles and mechanical impurities.

02

Highly Efficient Oil-Water Separation (Coalescing Core)

Core function relies on hydrophilic properties and excellent coalescing performance to demulsify and coalesce emulsified water into large droplets that settle by gravity for separation.

03

Diverse Materials and Stable Structure

Constructed using fiber media (e.g., glass fiber, polyester) or polymer media, providing superior chemical resistance and high structural stability for efficiency and longevity.

04

Broad Application Scope for Liquid Media

Widely used for dewatering and purification of various liquids, including all types of fuels (e.g., aviation fuel, diesel), lubricating oils (e.g., turbine oil, hydraulic oil), and aromatics/alcohols/ketones.

FAQ

What is a coalescing filter element and how does it work?

A coalescing filter element removes fine solid particles while separating dispersed water droplets from fuels, oils, and other liquid media. Small droplets are captured within the filter media and gradually combine into larger droplets, which can then settle by gravity and be separated from the main fluid stream.

What types of fluids are suitable for this coalescing filter element?

How do I choose the right micron rating for a coalescing filter element?

What affects oil-water separation efficiency in a coalescing filter?

When should a coalescing filter element be replaced?

How do I select the correct coalescing filter element for my existing system?
