Product Introduction
The HFU660UY1000H4 belongs to a family of large-flow, pleated cartridge filters. This series is typically produced as direct or compatible replacements for filters from major OEMs (like Pall, 3M, Parker). A key design feature is its large diameter (152-165 mm), which, combined with a folded media design, provides an extensive filtration surface area. This design drastically reduces the number of cartridges and filter housings required in a system, offering a cost-effective solution for high-flow industrial applications.
Filtration Precision
Filtration precision is customizable. Standard micron ratings available across the HFU660 series include 1, 5, 10, 20, 40, 70, and 100 micrometers (µm). A common standard precision is 5 µm.
Flux
Designed for high single-cartridge throughput. The specific flux is highly dependent on the cartridge length. Based on technical data for similar models, approximate maximum water flow rates are:
20-inch length: ~660 liters per minute (LPM)
40-inch length: ~1300 LPM
60-inch length: ~1900 LPM
Salt Rejection Rate
Not Applicable (N/A). The HFU660UY1000H4 is a mechanical depth filter. It removes suspended particles based on size exclusion and does not separate dissolved salts. Its primary role is often to serve as a pre-filter (or “guard filter”) for downstream Reverse Osmosis (RO) systems that perform desalination.
Pressure Drop
The pleated design aims for a low initial pressure drop. The recommended standard for replacing these cartridges across the series is when the differential pressure reaches 2.4 bar (at 20°C). The maximum allowable operating pressure drop can be as high as 3.4 bar at 82°C.
Molecular Weight Cutoff (MWCO)
Not Applicable (N/A). The concept of Molecular Weight Cutoff (MWCO) is specific to membrane separation processes like Ultrafiltration (UF) and Nanofiltration (NF). This is a depth filter cartridge that operates on a micron-based particle size exclusion principle.
Membrane Thickness
Not Applicable (N/A). This is a pleated depth filter, not a thin-film membrane element. Its separation is performed by a thick, porous media (such as polypropylene or glass fiber). Therefore, “membrane thickness” is not a defined parameter. The key structural elements are the filter media and its support skeleton.
Replacement Cycle
There is no fixed time-based cycle. Service life is determined by the increase in differential pressure. The cartridge must be replaced when the pressure drop reaches the recommended terminal value (typically 2.4 bar at 20°C), indicating the media is saturated with contaminants. The actual cycle depends entirely on feed water quality and system operating hours.
Features
High Single-Cartridge Flow: Reduces the number of filter vessels needed, lowering system footprint and cost.
Large Dirt-Holding Capacity: The extensive pleated surface area provides long service life and high contaminant loading.
Robust Construction: Features include internal/external polypropylene (PP) support skeletons and reinforced end caps for structural integrity.
Material Flexibility: Filter media can be Polypropylene (PP) or Glass Fiber (GF), with seal options like EPDM or Nitrile rubber for chemical compatibility.
High Filtration Efficiency: Can achieve high Beta ratios (βx≥1000), indicating ≥99.9% removal efficiency for its rated particle size.
Application Fields
This series is a versatile pre-filter for industrial processes requiring large-volume particulate removal:
Water Purification: Pre-treatment for Reverse Osmosis (RO) systems, ultrafiltration, and seawater desalination pretreatment.
Power Generation: Condensate water filtration, particularly for removing metal oxides (e.g., iron) in power plants.
Process Industries: Filtration in petrochemical, pharmaceutical, food & beverage (e.g., bottled water, wine, juices), and electronics (high-purity water) sectors.
Conclusion
In summary, the HFU660UY1000H4 is inferred to be a high-flow, pleated depth filter cartridge within the well-established HFU660 series. Its design prioritizes high single-cartridge throughput, extended service life, and reduced system complexity. It serves as a critical component for protecting sensitive downstream equipment (like RO membranes) through efficient mechanical removal of suspended solids.
