Fiberglass Material High Flow Filter for UF Pretreatment
Fiberglass material High Flow Filteris a high-performance pleated filter cartridge used for industrial ultrafiltration pretreatment. This liquid filter has excellent particle holding capacity and stable filtration performance under high flow working conditions. Our product portfolio contains Replace 3M 740B Series High-Flow Cartridge and 3M High-flow water filter cartridge to build multi-stage prefiltration skids for raw water treatment. Fiberglass material high flow filter can effectively intercept fine solid contaminants and protect ultrafiltration membranes in power, chemical, oil & gas and water reuse projects.
Fiberglass material High Flow Filter is a wide-diameter pleated filter consumable specially developed for industrial ultrafiltration pretreatment and high precision liquid filtration. Different from conventional polypropylene high flow filter cartridges, this product adopts high-strength fiberglass as the main filter medium. The fiberglass medium features smaller pore structure, superior particle retention efficiency and stronger temperature resistance, making it ideal for working conditions that require fine particle removal before ultrafiltration equipment. Installed on the upstream side of UF membrane modules, fiberglass material high flow filter captures fine silt, iron oxide, colloids and suspended solids from raw water before fluid enters ultrafiltration membranes. It greatly reduces membrane fouling risk, extends the service life of expensive membrane elements and reduces the frequency of chemical cleaning operations for the whole water treatment system.
Compared with ordinary PP high flow filter elements, fiberglass filter medium has gradient pore structure from outer layer to inner layer, which achieves deep filtration instead of simple surface interception. This feature brings much higher dirt holding capacity, longer service cycle and stable filtration precision. Thanks to the large diameter design, a single fiberglass material high flow filter can handle large liquid throughput. Fewer cartridges are needed inside filter housings, lowering spare part management cost and simplifying on-site replacement work. When designing full water treatment skids, system integrators can match this fiberglass filter with PFTM102UNPFC high flow filter cartridge and Parker MFNP010-40N Mega-Flow Filter to form gradient multi-stage raw water prefiltration.
The filter cartridge adopts thermal fusion end cap sealing without adhesive bonding. Fiberglass filter media is compounded with support layers, and integrated with polypropylene end caps and inner/outer support skeletons. This manufacturing method eliminates adhesive dissolution and secondary contamination risk. The fiberglass medium has good chemical tolerance to neutral liquids, weak acid and weak alkali solutions. It is widely chosen for industrial projects that demand strict fine particle filtration before ultrafiltration systems. Whether customers are retrofitting existing UF water lines or purchasing spare filters for newly commissioned ultrafiltration equipment, fiberglass material high flow filter can deliver consistent and reliable pretreatment filtration performance.
Fiberglass material High Flow Filter adopts gradient depth filtration mechanism. Raw liquid enters the filter housing and flows radially inward from the outer surface of the pleated fiberglass medium. Larger sediment and rust particles are trapped on the outer pleated layer. Tiny colloids and fine particulate pollutants penetrate into the multi-layer fiberglass fiber structure and get intercepted inside the staggered fiber gaps.
The unique gradient pore design of fiberglass medium means pore size gradually decreases from outside to inside. Pollutants of different particle sizes are trapped in different medium layers, instead of accumulating only on the outermost surface. This evenly distributes captured contaminants across the filter medium, slowing the rise of inlet and outlet differential pressure, maximizing dirt holding volume and extending filter service time. When pressure difference reaches the preset threshold, the medium is saturated with intercepted impurities, and operators need to replace the fiberglass material high flow filter.
This filter serves as the critical first-stage protection barrier for ultrafiltration membranes. Without effective upstream prefiltration, fine particles in raw water will directly scour UF membrane surface, block membrane pores and accelerate irreversible fouling. When used in series with PFTM11UEPFB high flow filter cartridge for multi-stage combined filtration, the overall stability of ultrafiltration equipment will be significantly improved. It should be noted that fiberglass material high flow filter can only remove solid particulate contaminants, and it cannot filter dissolved ions. It functions as mechanical prefiltration before ultrafiltration membranes.

Each batch of fiberglass material high flow filter passes full-process inspection and finished-product performance testing before delivery. Raw material inspection is implemented for fiberglass filter media, support cores and end caps to guarantee stable batch-to-batch quality consistency. During the production process, sampling inspection covers pleating uniformity, medium tensile strength, thermal sealing integrity and end cap bonding performance.
Finished product tests include bubble point integrity test, pressure impulse cycle test, flow-pressure drop test and particle retention efficiency test. Products with medium cracks, poor sealing or loose structures will be fully screened out. The glue-free thermal fusion sealing avoids adhesive leaching and liquid contamination. The fiberglass medium has stable structure and low fiber shedding rate under continuous liquid flushing, suitable for high-precision industrial pretreatment scenarios.
All products follow strict industrial filtration quality management standards. Each filter is individually packaged to prevent dust and particle pollution during storage and transportation. Complete technical datasheets are provided for engineering design, BOM list making and customer quotation reference. After filter installation and before system startup, users should inspect the filter housing interface and sealing condition to ensure no leakage occurs.
Fiberglass material High Flow Filter is mainly applied as pretreatment filter for ultrafiltration water treatment systems, and also widely used in many other industrial liquid filtration scenarios.
Industrial ultrafiltration system pretreatment: Intercept fine particles, iron scale and colloids, protect UF membrane elements, reduce membrane fouling and chemical cleaning frequency. Suitable for raw water purification and industrial wastewater reuse projects.
Power plant water treatment: Pre-filtration for boiler feed water and condensate water, removing fine suspended particulate impurities.
Oil & gas industry: Produced water pretreatment before ultrafiltration, removal of fine silt and oil solid residues.
Chemical industry: Process liquid filtration and circulating water pretreatment for chemical production lines.
Municipal water reuse: Large flow raw water prefiltration for wastewater recycling plants.
Fine chemical production: Pretreatment filtration of process water for fine chemical manufacturing.
System designers can configure multi-stage gradient filtration scheme according to raw water pollutant composition and turbidity of each individual project to optimize overall filtration effect.
A: Fiberglass medium has gradient depth filtration structure, better fine particle interception efficiency, higher temperature resistance and larger dirt holding capacity. It is more suitable for working conditions that require removal of ultra-fine particles before ultrafiltration equipment.
A: There is no fixed replacement cycle. Service life depends on raw water turbidity, pollutant concentration and operating flow rate. It is recommended to replace the filter once inlet-outlet differential pressure reaches 0.35 MPa.
A: It is disposable pleated filter cartridge. Once fiber gaps are saturated with trapped contaminants, backwashing cannot fully restore original filtration performance. Reuse will bring particle leakage risk, direct replacement is recommended.
A: It fits 40-inch or 60-inch high flow filter housings with bayonet locking interface. Before ordering, confirm housing size, internal space and pressure rating to prevent installation mismatch.
A: The maximum continuous operating temperature is 80℃. For working temperature exceeding this value, please contact our technical team for assessment and customized recommendation.
A: The required quantity is calculated based on total system flow rate, single filter rated flow and raw water quality parameters. Calculate with technical datasheet and reserve reasonable surplus to cope with raw water quality fluctuation.
