Technical Product Details

Coalescer Filter Cartridge Specifications

Our Coalescer Filter Cartridges are designed to separate dispersed liquid droplets, free water, oil aerosols, and fine contaminants from liquid or gas streams. The multi-layer media structure helps small droplets come together into larger droplets, making them easier to separate, settle, drain, or be removed by downstream separator elements.

Procurement Problems We Solve

Common Coalescer Filter Cartridge Problems We Help You Solve

Choosing a Coalescer Filter Cartridge is not only about cartridge size. Buyers also need to consider dispersed phase type, droplet size, flow rate, pressure drop, media compatibility, solids loading, separator vessel design, and replacement matching.

1. Free Water or Liquid Droplets Remain

Pain Point:

Fluids contain dispersed water, oil aerosols, or fine mist that cannot be removed by standard particle filters.

Business Impact:

Corrosion, fuel quality problems, equipment wear, and downstream process instability.

Our Solution:

Multi-layer coalescing media helps fine droplets merge into larger droplets for easier separation or drainage.

2. Wrong Cartridge Media for the Fluid

Pain Point:

Different fluids require different media compatibility, surface properties, and coalescing structures.

Business Impact:

Reduced coalescing performance, swelling, chemical attack, and premature cartridge failure.

Our Solution:

Glass fiber, fiberglass, PP, polyester, PTFE, and stainless steel mesh options based on fluid type and compatibility.

3. High Pressure Drop

Pain Point:

Inappropriate media density or small surface area creates excessive pressure drop.

Business Impact:

Reduced flow rate, increased energy consumption, and frequent maintenance.

Our Solution:

Match media area, micron rating, size, and flow direction to balance separation performance and pressure drop.

4. Performance Drops Quickly

Pain Point:

Solids contamination or incorrect pre-filtration reduces coalescing performance over time.

Business Impact:

Water carryover, repeated system contamination, and higher operating cost.

Our Solution:

Recommend suitable pre-filter stages, media structure, and micron rating according to solids load.

5. Replacement Mismatch

Pain Point:

Size, end cap, seal, flow direction, and connection details of replacement elements may not match existing housings.

Business Impact:

Leakage, bypass flow, installation failure, and separation performance loss.

Our Solution:

Replacement matching based on old model number, label, sample photo, drawing, and housing info.

6. Unclear Filter Selection

Pain Point:

Buyers may not know whether they need a coalescer, separator, pre-filter, or standard particle filter.

Business Impact:

Wrong filter selection leads to poor separation, unnecessary cost, or incomplete water removal.

Our Solution:

We compare fluid type, dispersed phase, flow rate, and vessel design before recommending the right cartridge type.

Coalescer Filter Working Principle

What Is a Coalescer Filter Cartridge?

Working Principle

A Coalescer Filter Cartridge is a separation filter element designed to remove fine liquid droplets, water, oil aerosols, and particles from a liquid or gas stream. As the fluid passes through the coalescing media, small dispersed droplets contact the filter fibers and merge into larger droplets. These larger droplets can then settle, drain, or be removed by a separator stage depending on system design.

Industrial Applications

Coalescer filter cartridges are commonly used in fuel filtration, oil-water separation, compressed air treatment, natural gas filtration, petrochemical processes, marine systems, power plants, and industrial process filtration.

Key Difference They are different from standard particle filter cartridges because their main function is not only particle capture but also droplet coalescence and phase separation.

Selection Criteria

When selecting a coalescer cartridge, buyers should consider fluid type, target contaminant, droplet size, flow rate, pressure drop, media compatibility, cartridge dimensions, end cap design, seal material, and replacement model requirements.

Selection Guide

How to Choose the Right Coalescer Filter Cartridge

Before placing an order, confirm the fluid type, separation target, droplet size, flow rate, pressure drop limit, cartridge size, media compatibility, end cap, seal material, and replacement model.

Selection Factor What You Need to Confirm Recommended Choice / What We Support
1. Separation Type Liquid-liquid or Gas-liquid separation? Determines media hydrophobicity/oleophobicity and structure.
2. Fluid Type Fuel, oil, compressed air, natural gas? Dictates media and seal material compatibility (e.g., FKM for certain oils).
3. Target Contaminant Free water, oil aerosol, fine mist? Helps select micron rating and specific coalescing layers.
4. Flow Rate Operating flow rate of the system. Determines cartridge size, quantity, and media area.
5. Cartridge Size OD, ID, Length, or housing dimensions. Custom sizing supported to match existing vessels exactly.
6. End Cap & Seal Open end, blind end, thread, O-ring type? Custom metal or plastic end caps; NBR, FKM, EPDM seals.

FAQ

Frequently Asked Questions

What is a Coalescer Filter Cartridge used for?

A Coalescer Filter Cartridge is used to separate fine liquid droplets, water, oil aerosols, and particles from liquid or gas streams. It helps small droplets merge into larger droplets so they can drain, settle, or be removed by a separator stage. It is commonly used in fuel filtration, oil-water separation, compressed air treatment, natural gas filtration, petrochemical processes, marine systems, and industrial process filtration.

What is the difference between a coalescer cartridge and a separator cartridge?

A coalescer cartridge is designed to capture fine droplets and merge them into larger droplets. A separator cartridge is usually used after the coalescer stage to prevent the separated liquid phase, such as water, from being carried downstream. In many systems, both work together. The coalescer performs droplet growth, while the separator improves phase separation.

Can Coalescer Filter Cartridges remove water from fuel or oil?

Yes. Coalescer Filter Cartridges are commonly used to help remove dispersed water or free water from fuels, oils, and other hydrocarbon fluids. Actual performance depends on fluid type, water concentration, interfacial tension, flow rate, media structure, solids loading, and separator vessel design.

Can you customize coalescer filter cartridges?

Yes. We support custom Coalescer Filter Cartridges by size, media, micron rating, flow direction, end cap, center tube, seal material, handle, label, and packaging. We can also match replacement elements based on old model numbers, drawings, sample photos, product labels, or housing dimensions.

How do I choose the right coalescing media?

The right coalescing media depends on the fluid type, target contaminant, droplet size, flow rate, temperature, chemical compatibility, pressure drop limit, and separation goal. Glass fiber, synthetic fiber, polypropylene, PTFE, stainless steel mesh, or custom media may be considered depending on application.

Why is pre-filtration important before a coalescer cartridge?

Solid particles can plug the coalescing media and reduce separation performance. In applications with high solids load, a pre-filter may help remove particles before the fluid reaches the coalescer cartridge. This can extend service life and improve separation stability.

Can you supply replacement coalescer cartridges for existing housings?

Yes. We can supply replacement coalescer cartridges based on old model numbers, labels, dimensions, end cap type, seal material, media structure, and sample photos. This is useful for maintenance teams, distributors, OEM projects, and industrial filter replacement programs.

What affects Coalescer Filter Cartridge price?

Coalescer Filter Cartridge price depends on cartridge size, media type, micron rating, end cap material, seal material, center tube, flow direction, compatibility requirement, testing requirement, order quantity, label, and packaging. Custom structures and special media may increase cost.
