This coalescer filter element is designed as a direct, high-performance replacement for original equipment coalescer filters, delivering exceptional separation efficiency for hydraulic oils, lubricating oils, turbine oils, diesel fuels, and other industrial fluids. By combining fine particulate filtration with advanced coalescing technology, it provides comprehensive fluid conditioning that protects critical components, prevents corrosion, and extends system service life.
The 130×485.5mm coalescer element utilizes specialized glass fiber or synthetic coalescing media engineered to capture and agglomerate microscopic water droplets suspended in oil. As fluid passes through the media, tiny water droplets adhere to the fibers, collide, and merge into larger droplets. These coalesced droplets then release from the downstream side and separate by gravity, draining to a collection sump. Simultaneously, solid particulate is captured by integrated filtration layers. This dual-action capability directly contributes to reduced oxidation, minimized additive depletion, lower maintenance costs, and enhanced equipment reliability across power generation, marine, steel, and heavy industrial applications.

This compact coalescer is essential in systems requiring precise phase separation:
Instrument & Control Air: Final polishing of compressed air for pneumatic instruments, control valves, and logic systems.
Small Compressor Aftercoolers: Removing oil and water aerosols from the discharge of small industrial or medical air compressors.
Natural Gas & Biogas: Dehydration and removal of compressor oil mist in small-scale gas streams.
Fuel Conditioning: Polishing of fuels (diesel, aviation fuel) to remove entrained water before sensitive injectors or engines.
Process Gas Lines: Protecting analytical equipment, sensors, and reactors from liquid carryover.
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.
