Product Introduction
The HFU660UY1000H4W is a high-flow, pleated cartridge filter designed for large-scale industrial water pretreatment. This model, belonging to the HFU series, is a direct replacement for original equipment manufacturer (OEM) cartridges from major brands like Pall. It features a large diameter and a single open-end design, utilizing a pleated polypropylene (PP) or glass fiber media to maximize filtration surface area. A key characteristic is its ability to handle extremely high flow rates, significantly reducing the number of filter housings needed in a system.
Filtration Precision
The cartridge is available in a range of standard filtration precision (micron) ratings. Common options include 1, 5, 10, 20, 40, 70, and 100 micrometers (µm). A common standard precision is 5 µm.
Flux
Engineered for high single-cartridge throughput, the flux is highly dependent on cartridge length. Based on technical data for the HFU series:
A standard 40-inch length cartridge can achieve a water flow rate of approximately 1300 liters per minute (LPM).
A 60-inch cartridge can handle up to 1900 LPM.
These high flow rates allow one cartridge to replace dozens of standard-sized filters.
Salt Rejection Rate
Not Applicable (N/A). This is a mechanical depth filter. Its function is the physical removal of suspended particles and solids based on size exclusion. It does not remove dissolved ionic salts. For desalination, this cartridge serves as a critical pre-filter for downstream Reverse Osmosis (RO) systems.
Pressure Drop
The pleated design provides a low initial pressure drop. The recommended standard for replacement across the HFU series is when the differential pressure reaches 2.4 bar (at 20°C). The maximum allowable pressure drop varies with media material and temperature, reaching up to 3.4 bar at 82°C.
Molecular Weight Cutoff (MWCO)
Not Applicable (N/A). MWCO is a parameter specific to membrane separation technologies like Ultrafiltration (UF) and Nanofiltration (NF). This pleated cartridge 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. It is a depth filter cartridge that utilizes a thick, pleated media (e.g., polypropylene or glass fiber) for particle capture. Therefore, “membrane thickness” is not a relevant technical parameter.
Replacement Cycle
There is no fixed time-based cycle. Service life is determined by the increase in differential pressure due to contaminant loading. The cartridge should be replaced when the pressure drop reaches the recommended terminal value (e.g., 2.4 bar at 20°C). The actual cycle depends entirely on the quality of the feed water.
Features
High Flow with Single Cartridge: Dramatically reduces the number of filter vessels required, saving space and lowering system costs.
High Dirt-Holding Capacity: The large diameter and deep pleats provide an extensive surface area for long service life and high contaminant loading.
Robust Construction: Features include internal and external polypropylene (PP) support skeletons and thickened end caps for structural integrity.
Material Versatility: 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 (e.g., β≥1000 for its rated particle size), indicating ≥99.9% removal efficiency.
Easy Handling: Often includes a handle for convenient installation and removal.
Application Fields
This high-flow cartridge is a versatile pre-filter used across industries requiring large-volume particulate removal:
Water Purification: Pre-treatment for Reverse Osmosis (RO) and Ultrafiltration (UF) systems, seawater desalination pretreatment.
Power Generation: Condensate water filtration in power plants, especially for removing metal oxides like iron.
Process Industries: Filtration in petrochemical, pharmaceutical, food & beverage (e.g., bottled water, wine), electronics (high-purity water), and chemical production.
Conclusion
In summary, the HFU660UY1000H4W is a high-performance, high-flow depth filter cartridge designed for large-scale industrial water pretreatment. Its core value lies in providing reliable, efficient protection for sensitive downstream equipment (like RO membranes) by removing suspended solids. Its design emphasizes extended service life, reduced system complexity, and lower overall operational costs.
