Replacement FACET Coalescer Filter

1. Product Overview

This coalescer filter element is a full equivalent replacement for original FACET filter cartridges, covering all standard CA and CM series model codes

shown in our catalog. It is manufactured from multi-layer composite materials via special production processes and features strong hydrophilic

demulsification performance.

The filter is specially designed for liquid fuel purification, mainly applied to diesel oil, aviation kerosene and other fuel treatment systems. It can

remove solid mechanical impurities and separate emulsified water mixed in fuel oil through demulsification and coalescence, gathering tiny water

droplets into large drops for complete separation, so as to purify fuel liquid and protect downstream precision pumps, valves and measuring

instruments.

2. Material & Layered Structure

The filter adopts integrated multi-layer composite winding structure with stable construction and reliable sealing performance:

(1) Outer Protective Non-woven Layer

Polypropylene non-woven fabric blocks large solid particles from directly scouring the inner filter media, preventing fiber shedding and extending

service life.

(2) Core Demulsification & Coalescing Medium

Special hydrophilic composite filter material is the core functional layer. It breaks emulsified liquid film, captures tiny water droplets suspended in oil

and merges them into large water beads for separation, with large dirt holding capacity and anti-clogging performance.

(3) Inner & Outer Support Mesh

304 stainless steel perforated support screens provide structural strength, resist liquid impact and slight medium corrosion, and will not deform

 under long-term working pressure.

(4) Reinforced End Caps

High-strength corrosion-resistant end caps bonded with high-temperature epoxy resin. The bonding joints are completely leak-proof, matching the

installation size of original FACET filter elements.

(5) NBR Sealing Rings

Oil-resistant nitrile rubber sealing rings fit perfectly with end cap grooves to avoid liquid bypass leakage, fully consistent with the sealing

specification of original FACET filters.

3. Working Principle

Liquid Flow Direction: Outside-in flow (fuel liquid enters from the filter outer wall and flows out through the central core)

(1) Solid Impurity Interception Stage

Contaminated fuel flows into the filter from the outside. The outer non-woven fabric and coarse filter layer trap rust, sediment and solid particle

impurities on the filter outer wall to finish solid-liquid separation.

(2) Demulsification & Water Droplet Coalescing Stage

Emulsified tiny water droplets mixed in fuel pass through the hydrophilic coalescing medium. The filter material breaks the oil-water emulsified film,

captures micro water droplets, and the droplets continuously collide and merge into large water beads under liquid flow.

(3) Water Settlement & Clean Fuel Output

Coalesced large water beads are heavier than fuel, sliding down the filter outer wall to the water collection tank at the bottom of the separator for

regular draining. Purified dry fuel flows through the inner support tube and exits from the filter center, completing liquid-solid and oil-water

two-phase purification.

4. General Product Advantages

(1) Overall dimension, mounting structure and sealing size are completely consistent with original FACET filters for direct plug-and-play replacement

 without equipment modification.

(2) Integrates solid impurity filtration and oil-water demulsification coalescence functions, effectively reducing equipment wear and instrument

 blockage caused by moisture and particles in fuel.

(3) Stainless steel support matched with hydrophilic composite coalescing media delivers excellent pressure and corrosion resistance, suitable for

 various fuel oil treatment working conditions.

(4) The composite filter media has large dirt holding capacity to prolong service life and reduce frequent equipment shutdown maintenance.

(5) Customizable filter length and filtration accuracy according to customer on-site working conditions; complete batch test reports can be provided.

5.FAQ

(1)Q: What medium is this coalescer filter suitable for?

    A: It is a liquid fuel coalescer filter, specially used for purification of diesel oil, aviation kerosene and other liquid oil, not for natural gas filtration.

(2)Q: Can it fully replace original FACET filter elements?

    A: Yes, all CA and CM series model sizes are 1:1 reproduced, which can be directly installed on FACET original separators.

(3)Q: What is the core function of this filter element?

    A: It can filter solid impurities in oil and break oil-water emulsion to separate suspended tiny water droplets from fuel.

(4)Q: What is the standard operating temperature range?

    A: It can work stably at -20℃ ~ 80℃ under normal fuel treatment environment.

(5)Q: Do you support customized filter specifications?

     A: We accept customization of filter length, accuracy and interface size based on your separator equipment parameters.
