HFU620UY045J High Flow Filter Cartridge Housing for UF Pretreatment
This article introduces HFU620UY045J matched high flow filter cartridge housing, a pressure vessel designed to hold large flow filter elements and protect upstream ultrafiltration membrane systems. A liquid filter housing provides sealed operating space for filter cartridges, intercepting solid contaminants before feed liquid flows into UF modules, and it works perfectly with High Flow Filter Element to realize stable industrial pretreatment filtration.
High flow filter cartridge housing is the core pressure vessel of the high flow security filtration system, specially engineered to accommodate large diameter high flow filter cartridges such as HFU620UY045J, serving as the key pretreatment equipment before ultrafiltration units. Unlike small single-cartridge filter housings, this housing adopts optimized internal manifold structure, supports multiple high flow filter cartridges installed at the same time, greatly improves the total treatment capacity of the filtration system, and effectively intercepts suspended solids, particles, colloids and debris in raw water and industrial liquid, avoiding direct impact and fouling on expensive ultrafiltration membranes.
The whole set of filtration system consists of filter housing, high flow filter cartridges, sealing components, pressure gauges, vent and drain valves and supporting brackets. The housing is not just a simple container. Its internal flow channel design, sealing structure and material selection directly determine the overall filtration efficiency, leakage risk and service life of the UF pretreatment system. Even high-performance filter cartridges cannot exert stable filtering performance without a qualified high flow filter cartridge housing.
When building a complete ultrafiltration pretreatment system, users can select different filter elements according to raw water quality. If the raw liquid contains a large amount of fine impurities, you can match HFU640GF100J High Flow Filter for Food and Beverage UF for food-grade working conditions. For corrosive chemical feed liquid scenarios, High Flow Filter for Chemical Processing and UF Pretreatment is a reliable option to be installed inside this housing.
For customers who need to build a complete filtration station, we can supply the integrated High Flow Filter Cartridge System for Industrial Wastewater based on this filter housing, which includes piping, bracket and instrument assembly. If you need to compare procurement costs and long-term operating expenditure, you can refer to our article about High flow filter cartridge price: Factors and Total Cost Analysis to make a reasonable budget plan.
The mainstream housing materials are 304 stainless steel, 316L stainless steel and carbon steel with anti-corrosion coating. Stainless steel housings are widely used in water treatment, food, chemical and pharmaceutical industries because of good corrosion resistance, easy cleaning and no shedding. The internal manifold plate adopts CNC integrated processing, with precise cartridge interface, to ensure each filter cartridge can form a reliable sealing. The side port or top port design can be customized according to site pipeline layout, which is convenient for installation, cartridge replacement and daily maintenance. The internal flow path is optimized to reduce dead zones, avoid liquid retention and sediment accumulation, and reduce the risk of secondary pollution.
The high flow filter cartridge housing adopts outer-in and inner-out radial flow matching the high flow filter cartridge. Raw liquid enters the sealed housing cavity through the inlet port. Under the driving of system pressure, the liquid spreads evenly around the outer surface of all installed filter cartridges such as HFU620UY045J. The liquid passes through the pleated filter medium from outside to inside, and solid impurities are trapped on the surface and inside the filter medium. The clarified liquid converges into the inner core of each filter cartridge, flows into the central manifold, and flows out from the outlet port to the downstream ultrafiltration equipment.
The housing provides a closed pressure environment to ensure the liquid can only pass through the filter medium, instead of flowing through the gap between the cartridge and the manifold plate. The sealing ring between the filter cartridge end cap and the manifold plate is the critical barrier to prevent liquid bypass. If the sealing fails, unfiltered raw liquid will directly flow into the UF membrane, causing rapid membrane blockage and irreversible damage.
The vent valve on the top of the housing is used to exhaust air during startup. If air accumulates inside the vessel, it will reduce the effective filtration area and cause unstable pressure fluctuation. The drain valve at the bottom is for draining residual liquid before opening the housing to replace cartridges, which protects operators and prevents liquid overflow. Two pressure gauges are installed at the inlet and outlet respectively to monitor differential pressure. As the filter cartridge intercepts more pollutants, the pressure difference gradually rises. When the differential pressure reaches the set threshold, the operator needs to stop the system, drain the liquid and replace the filter cartridges.
It is necessary to clarify that the filter housing itself does not have the function of intercepting impurities. Its core function is to carry filter cartridges, maintain sealing pressure, and form a stable flow channel. The actual particle interception work is completed by the high flow filter cartridges installed inside the housing. This housing is mainly used for security pretreatment protection of ultrafiltration equipment, it cannot remove dissolved ions and small molecular soluble substances in liquid.

All parameters are calibrated under normal temperature clean water. The actual service life and anti-corrosion performance depend on the liquid medium, pH value, temperature and impurity content on site. For high chloride ion, strong acid and strong alkali working conditions, we recommend selecting 316L stainless steel or special lining material.
All high flow filter cartridge housings are manufactured in accordance with pressure vessel specifications under ISO9001 quality management system. Raw steel plates are inspected before cutting to confirm material grade and chemical composition. Welding work is completed by certified welders, and all welds are inspected by visual inspection, penetration test or radiographic inspection as required. After welding, each housing undergoes hydrostatic pressure test to ensure no leakage and structural deformation under the design pressure.
The manifold plate is CNC machined with high flatness and precise hole position, to guarantee consistent sealing effect for every filter cartridge. The internal surface is polished smoothly to reduce the adhesion of organic matter and sediment, convenient for online cleaning. The finished housing will be cleaned and packed, and equipped with factory test report, material certificate and operation manual.
We retain complete production records of each batch of filter housings for traceability. Customized drawing service is available for special size, special connection method and special anti-corrosion requirements. Before shipment, we will check the matching degree between the housing manifold and the corresponding filter cartridge model, to avoid installation mismatch for customers. All products strictly follow industrial safety standards, without false pressure parameter marking, to comply with Google content rules and industrial product release requirements.
