P.4‑279 Coalescer Filter Element, Faudi Replacement for Petrochemical Fuel Purification

Petrochemical plant light‑hydrocarbon purification requires stable Faudi‑system coalescing consumables, Oil Filtration Machine provides complete interchange solution. P.4‑279 coalescer filter element belongs to Faudi P‑series coalescer cartridge, designed for petrochemical filter‑separator vessels, accomplishing emulsion breaking, water coalescing and fine‑solid contaminant interception.

P.4‑279 utilizes progressive gradient glass‑fiber coalescing media. When polluted light‑hydrocarbon fluid flows radially from outer side toward inner core, stable emulsified water droplets are captured by media layers and merge into larger droplets. Enlarged water droplets are transported with fluid to downstream Faudi separator filter element to achieve liquid‑liquid separation. Optimized media structure balances dirt‑holding capacity and low initial pressure‑drop performance.

Our Faudi P‑series coalescer covers P.4‑279, P.4‑362, P.4‑559, P.4‑727, P.4‑842, P.4‑965, P.4‑1093, P.4‑1422, P.7‑362, P.7‑1093. These P‑type coalescer cartridges are fully mechanically interchangeable into original Faudi filter‑separator housings. Every finished cartridge undergoes ISO‑standard burst resistance and media integrity inspection. Check full‑range product: Gas Filter Element.

P.4‑279 is widely used for petrochemical intermediate‑liquid treatment, refinery kerosene & diesel dehydration, large‑scale fuel storage depot processing. Must match Faudi‑series separator filter element to complete two‑stage separation workflow. More system solution: Industrial Oil Purification Equipment.

FAQ

Q: Can P.4‑279 replace original Faudi P‑series cartridge?

A: Yes, same outer dimension, inner dimension and mounting interface for direct swap‑out.

Q: What is operating principle for P.4‑279 coalescer filter element?

A: Multi‑layer gradient glass‑fiber breaks oil‑water emulsion and coalesce micro water droplets into large drops.

Q: What contaminants can P.4‑279 remove?

A: Emulsified water, fine rust particles, pipeline scale and other solid impurities in light‑hydrocarbon.

Q: What replacement differential pressure shall be followed?

A: Recommend full‑set coalescer‑separator replacement when differential pressure reaches 12‑15 psi.
