The custom dehydration coalescer filter element is a high-performance filtration cartridge specifically engineered for the removal of both particulate contaminants and free/emulsified water from industrial fluids. This oversized coalescer element is designed for heavy-duty filter-separator vessels and coalescing dehydration systems serving demanding industries including jet fuel handling, power generation turbine oil conditioning, hydraulic and lubrication circuits, petrochemical processing, and marine fuel management.
Unlike standard particulate filters that only capture solid particles, a coalescer filter element is a depth-type filtration solution engineered for the high-precision separation of immiscible liquids, such as oil and water. It combines precision particle filtration with high-efficiency dehydration using advanced “coalescence separation” technology. As the fluid passes through the specialized multi-layer media, microscopic water droplets are merged into larger droplets, which are then separated by gravity and drained away, while solid contaminants are captured simultaneously.

This compact coalescer is essential in systems requiring precise phase separation:
Huahang Filter‘s coalescing filter elements embody our expertise in coalescing separation technology. We understand the precision engineering required for effective coalescing.
Q: How do I confirm this coalescer filter element will fit my housing?
A: The most reliable method is to verify the exact outer diameter , overall length , seal type, and end cap configuration against your current element. If you have a drawing or sample, our technical team can cross-reference it for perfect compatibility.
Q: How does a coalescer element differ from a standard hydraulic filter?
A: A standard hydraulic filter removes solid particulate only. A coalescer element is specifically engineered to also remove free and emulsified water by causing microscopic water droplets to merge into larger droplets that separate by gravity. This is essential in systems where water contamination causes corrosion, oil degradation, and component wear.
Q: What is the typical water removal efficiency?
A: Under proper operating conditions, the coalescer element can achieve >99% removal of free and emulsified water, reducing water content to well below 100 ppm (parts per million). Actual efficiency depends on fluid viscosity, temperature, flow rate, and influent water concentration.
Q: Can I use this element with fire-resistant fluids like phosphate ester?
A: The standard construction is compatible with mineral oils and common synthetics. For phosphate ester (HFD-R/S), water-glycol (HFC), or other specialty fire-resistant fluids, please contact our technical team to verify seal and media compatibility before ordering.
Q: How does the coalescing process work?
A: The coalescing media (typically glass fiber) is engineered with oleophilic (oil-attracting) and hydrophobic (water-repelling) properties. As oil passes through, tiny water droplets adhere to the fibers, collide with other droplets, and merge (coalesce) into progressively larger droplets. These larger droplets are then released from the downstream side of the media and settle by gravity into the collection sump of the filter housing.
