The CA333SB coalescer filter element is a direct, high-quality replacement for original equipment coalescer filters used in natural gas transmission, gas processing, compressed air systems, and marine oily water separation applications. It provides reliable removal of both solid particulates and liquid aerosols—including water droplets, hydrocarbon condensate, and oil mist—from gas and liquid streams, protecting downstream equipment such as compressors, meters, regulators, and control valves from corrosion, fouling, and efficiency loss.
The CA333SB element is also widely employed in marine bilge water separation systems , helping vessels meet stringent international discharge regulations by effectively coalescing oil droplets from water before overboard discharge.

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 can I confirm this filter will fit my specific housing?
A: This product is a direct cross-reference for part numbers CA333SB. The surest method is to verify that either of these numbers is listed in your equipment’s service manual, parts guide, or is printed on the filter currently installed in your system.
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.
Q: Is this filter compatible with fire-resistant hydraulic fluids?
A: The standard glass fiber construction is compatible with a wide range of mineral-based hydraulic oils and common synthetics. For use with phosphate ester , water-glycol , or other specialty fire-resistant fluids, verification of chemical compatibility with the filter media and seals is strongly recommended prior to installation. Please specify your fluid type when ordering.
Q: What is the recommended service interval?
A: Replacement intervals depend on your system’s operating conditions, fluid type, water content, and contamination levels. Always prioritize the service interval specified in your equipment manufacturer’s manual. The most accurate method is to monitor the pressure differential across the filter housing and replace the element when the delta-P reaches the manufacturer’s recommended limit. Additionally, monitoring fluid water content can indicate when coalescing efficiency has degraded.
