Products Description
Customized PCHG312 Fuel Filter Coalescing Oil Water Separation Filter element .Glass fiber sintered filter elements are depth-type filtration media manufactured from high-purity borosilicate glass fibers via a high-temperature sintering process. They feature a three-dimensional reticulated pore structure with controllable pore size distribution and high void volume, and are classified as rigid or semi-rigid media.Customized PCHG312 Fuel Filter Coalescing Oil Water Separation Filter element.
Key Features
Superior Filtration Efficiency: Offers high retention rates for submicron particles (≥0.1μm) with consistent, reliable precision.
High Dirt-Holding Capacity: The deep-bed configuration enables substantial solids loading, effectively prolonging service intervals.
Broad Thermal & Chemical Compatibility: Operational across a wide temperature range (typically –40°C to 260°C) and resistant to most organic solvents, acids, alkalis, and oils.
Low Extractables & Shedding: The sintered structure ensures minimal fiber release or leachables, making it ideal for high-purity applications.
Excellent Mechanical Rigidity: Maintains structural integrity under high differential pressures and withstands pulsed or high-velocity flow conditions.
Cleanable & Reusable: Compatible with chemical cleaning, ultrasonic cleaning, and backwashing, allowing multiple reprocessing cycles.
Application Areas
Petrochemical & Chemical Processing: Polymer melt filtration, catalyst recovery, and amine solution purification.
Pharmaceutical & Biotechnology: Sterile gas/liquid filtration for drug manufacturing and fermentation air sterilization.
Food & Beverage: Edible oil clarification, wine/beer polishing filtration, and process water treatment.
Electronics & Semiconductor: High-purity wet chemical filtration, CMP slurry conditioning, and UPW (ultrapure water) point-of-use filtration.
Environmental & Water Treatment: Advanced industrial wastewater treatment, reclaimed water pretreatment, and oilfield produced water re-injection filtration.
Service Life
Service life is highly dependent on operating conditions, including feed contamination level, temperature, differential pressure, and cleaning frequency. Under proper maintenance and regular cleaning, a typical service life ranges from 6 months to 2 years. In clean applications or when used as a pre-filter/protective filter, longer lifetimes can be achieved. The actual replacement schedule should be determined by monitoring the differential pressure rise trend (ΔP) and downstream quality indicators.

FAQ
Q: What impurities can the coalescing filter element remove?
A: It primarily removes emulsified and free water from oil, while also capturing a certain amount of solid particles.
Q: How to determine when the filter element needs replacement?
A: Typically by pressure differential (reaching alarm value), excessive water content after filtration, or reaching the recommended service period.
Q: Is the filter element compatible with different brands of filter housings?
A: Compatibility depends on dimensions, port type, and seal design. Customization is available upon request.
Q: What materials are used in the filter element?
A: The coalescing layer is usually fiberglass or special resin; the separating layer is stainless steel mesh or hydrophobic material. End caps and cages are often carbon steel or stainless steel.
