Coalescing Separation Filter Element – Dual-Stage Dehydration & Particle Removal

Product Overview

Our Coalescing Separation Filter Element features a two-stage coalescence-separation

 structure that simultaneously captures solid particulates and separates free water entrained

 in fuel oil, providing an effective solution to water contamination issues in oil media.

Unlike conventional single-function filter cartridges, this element integrates both

 a coalescing layer and a separation layer. As a professional manufacturer of import-substitution 

filter consumables, we deliver stable dehydration efficiency, extended service life,

 and competitive total cost of ownership for applications including oil depots, power plants, 

and engineering machinery fuel systems.

Core Advantages

Dual-Function Filtration & Dehydration

Integrates particle interception with oil-water separation in a single operation,

 removing solid impurities and free water simultaneously.

Gradient Composite Filter Media

Specialized coalescing material enables fine water droplets to collide, coalesce, 

and grow into larger droplets for rapid, efficient separation.

High Dirt-Holding Capacity

Slow differential pressure rise extends service intervals, reducing the frequency and 

cost of element replacements.

Stable Structural Strength

Internal reinforced support prevents media deformation under flow surges, 

ensuring long-term operational stability.

Cost-Effective Import Substitution

Factory-direct pricing delivers performance comparable to original imported coalescing elements, 

with significantly shorter lead times.

Installation & Operation Guidance

· Confirm flow direction marking prior to installation

· Avoid violent impact or scratching of filter media during assembly

· Replace the element once the system differential pressure reaches the alarm setpoint

· Keep storage environment dry; avoid prolonged exposure to damp conditions

FAQ

Q1: Can this filter element remove dissolved water from fuel oil?

A1: It is primarily effective for free water and suspended water droplets. 

It cannot remove water that has dissolved at the molecular level within the medium.

Q2: What fluids are compatible with this element?

A2: Suitable for diesel fuel, fuel oil, and low-viscosity mineral hydraulic oils.

Q3: Can it directly replace imported coalescing separation filter elements?

A3: Yes. We support custom sizing and performance parameters to ensure direct

 interchangeability according to original specifications.
