CA28‑9SB Screw‑Base Coalescer Filter Cartridge For Bulk Fuel Terminals
CA28‑9SB screw‑base coalescer filter cartridge from LEFILTER, high‑flow coalescer filter element for aviation and refinery fuel dehydration, works as coalescer cartridge filter to break emulsified water inside light hydrocarbon fluid.
Product Introduction
Oil Filtration Machine from LEFILTER delivers reliable Coalescer Filter replacement parts for global refinery and aviation‑fuel sites. CA28‑9SB coalescer filter cartridge is a popular screw‑base coalescer filter element. As a high‑throughput coalescer cartridge filter, this coalescer cartridge is engineered for screw‑mount fuel filter‑separator housings, widely applied for bulk fuel receiving terminals and large‑capacity refinery light‑hydrocarbon workflows.
This coalescer filter adopts multi‑layer gradient glass‑fiber coalescing media. When polluted jet‑A1 or diesel fuel flows outside‑to‑inside through media layers, stable oil‑water emulsion will be broken. Micro emulsified water droplets collide and merge into large‑size settleable droplets. Reinforced screw‑base end‑cap improves sealing performance under frequent flow surges. LEFILTER’s CA‑series covers CA11‑9, CA14‑5SB, CA22‑3, CA28‑9, CA28‑9SB, CA33‑5, CA38‑3SB, CA43‑9SB for diversified site requirements.
Every CA28‑9SB coalescer filter cartridge passes ISO 2941 collapse‑burst test, ISO 2942 media integrity test and ISO 2943 fluid compatibility test before LEFILTER factory shipment. This coalescer cartridge filter cannot run independently and must pair with matched screw‑base separator cartridge to realize complete two‑stage liquid‑liquid separation.

Frequently Asked Questions
Q: What working media is compatible with CA28‑9SB coalescer filter element?
A: Jet‑A1 aviation fuel, kerosene, diesel and other light‑weight hydrocarbon fuels.
Q: What does SB suffix stand for in CA28‑9SB model?
A: SB means screw‑base mounting interface, not interchangeable with rod‑mount coalescer cartridge.
Q: Can I mix different mounting‑style cartridges in one filter‑separator vessel?
A: Not allowed, mismatched mounting will create fluid bypass and reduce filtration performance.
Q: When should we replace full coalescer‑separator set?
A: Replace coalescer and supporting separator together once system differential pressure reaches 12‑15 psi.
