High-Efficiency Coalescing Filter Element for Fuel & Oil Water Separation


I. 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.

II. 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."
  1. 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 OF COALESCING FILTER ELEMENTS

 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.

 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.

 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.

 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.

Do you accept OEM/ODM for filtration products?

Yes, OEM/ODM is available. Send your detailed requirements to us.We are analyse it and provide  professional solutions and proposals for your choice and help design appropriate filters.


What's the service life of the filter cartridge?

The service life of the filter cartridge is affected by the use environment, frequency of use, the original media state, and the type of filter cartridge. Please provide us with more detailed information and our technical team will help evaluate it.


What are the key factors in selecting the right filter cartridge?

Key factors include micron rating, flow rate, chemical compatibility, operating pressure, temperature, and the type of contaminants to be removed. Our engineers can help you choose the optimal filter element for your application.


How often should filter cartridges be replaced?

Replacement intervals depend on operating conditions, contaminant load, and pressure drop. Regular monitoring and our technical support can help optimize maintenance schedules and reduce downtime.
