Product Introduction
The HFU660UY100H4 is a member of the HFU series of industrial-grade, high-flow water filter cartridges. Designed as direct or compatible replacements for filters from major brands like Pall (Pall), these cartridges feature a 6-inch (152mm) large diameter and a single-open-end design without a center support core. The fluid flows from the inside out, and the unique large-diameter, pleated construction significantly increases the effective filtration area. This allows for reduced numbers of cartridges and smaller housing sizes in a system, lowering investment and operational costs.
Filtration Precision
This model series offers a range of customizable filtration ratings. The available standard precision levels include 1, 5, 10, 20, 40, 70, and 100 micrometers (µm). Other common options like 4.5µm and 6µm are also available within the series.
Flux
Flux is a key feature of the HFU series. A single cartridge is engineered for extremely high flow rates, which vary depending on the cartridge length (20″, 40″, or 60″). For reference, a 40-inch (1016mm) length cartridge in this series has a recommended maximum water flow of 1300 liters per minute (LPM). This is equivalent to approximately 78 cubic meters per hour (m³/h).
Salt Rejection Rate
Not Applicable (N/A). This cartridge is a mechanical depth filter, not a semi-permeable membrane. Its function is the physical removal of suspended solids and particulate matter based on size exclusion. It has zero capability to remove dissolved ionic salts. For desalination, this cartridge is typically used as a pre-filter (or “guard filter”) to protect downstream Reverse Osmosis (RO) systems.
Pressure Drop
Maximum Pressure Drop: The cartridge is designed to withstand operational pressures. For a cartridge using polypropylene (PP) filter media, the maximum allowable pressure drop is 3.4 bar at an operating temperature of 82°C.
Replacement Indicator: The cartridge should be replaced when the differential pressure (pressure drop) across it reaches 2.4 bar (measured at 20°C).
Molecular Weight Cutoff (MWCO)
Not Applicable (N/A). MWCO is a parameter specific to membrane separation processes like Ultrafiltration (UF) and Nanofiltration (NF), which separate solutes based on molecular size. This is a pleated depth filter cartridge that operates on a micron-based particle size exclusion principle and does not have an MWCO rating.
Membrane Thickness
Not Applicable (N/A). This product is not a thin-film membrane element. It is a depth filter cartridge that utilizes a thick, porous, and pleated filter media (such as polypropylene or glass fiber). Therefore, “membrane thickness” is not a relevant technical parameter.
Replacement Cycle
There is no fixed time-based replacement cycle. The service life is determined by the increase in differential pressure across the cartridge due to contaminant loading. The cartridge must be replaced when the pressure drop reaches the recommended terminal value of 2.4 bar. The actual cycle depends entirely on the quality of the feed water.
Features
High Single-Cartridge Flow: Significantly reduces the number of filter housings required, saving space and cost.
High Dirt-Holding Capacity: The large diameter and deep pleats provide extensive surface area, resulting in long service life.
Robust Construction: Features include support/flow guides made of polypropylene and end caps made of glass fiber-reinforced polypropylene.
Material Versatility: The filter media can be Polypropylene (PP) or Glass Fiber. Seals are typically made from EPDM (Ethylene Propylene Diene Monomer) or Nitrile (NBR) rubber.
Wide Operating Temperature: Depending on the media, it can operate up to 82°C for PP and 120°C for glass fiber.
Application Fields
This high-flow cartridge is a versatile pre-filter across numerous industries requiring large-volume particulate removal:
Water Purification: Pre-treatment (security filtration) for Reverse Osmosis (RO) systems and seawater desalination plants.
Power Generation: Condensate water filtration in power plants.
Food & Beverage: Filtration of bottled water, juices, soft drinks, milk, edible oils, and syrups.
Pharmaceutical & Biotechnology: Filtration of process water, solvents, and raw medicinal liquids.
General Industry: Process water filtration in petrochemical, microelectronics, and paint industries.
Conclusion
In summary, the HFU660UY100H4 is a high-performance, high-flow depth filter cartridge from the established HFU series. Its core value lies in providing reliable, high-efficiency protection for sensitive downstream equipment (like RO membranes) by removing suspended solids. The design prioritizes extended service life, reduced system complexity, and lower overall capital and operational costs through high single-cartridge throughput.
