Product Introduction
The HFU660UY1000H belongs to the HFU series of large-flow, pleated filter cartridges. It is designed with a 6-inch (152-165 mm) diameter and has a single open end with no central support skeleton. Its primary function is high-flow depth filtration to remove particulate matter and is commonly used as a protective pre-filter (or “保安过滤器”) for sensitive systems like reverse osmosis (RO) and ultrafiltration (UF).
Filtration Precision
The cartridge is available in a range of customizable filtration precisions. Standard options include 1, 5, 10, 20, 40, 70, and 100 micrometers (µm). For specific industrial applications, such as power plant filtration, a precision of 5 µm is commonly specified.
Flux
A single cartridge is engineered for very high flow rates. Technical data from similar models in the HFU660 series suggests a maximum operating water flow of approximately 1300 liters per minute (LPM) for a 40-inch length cartridge, equivalent to about 78 cubic meters per hour. A characteristic of the series is that a single high-flow filter can replace up to 30 standard-sized filter cartridges, significantly simplifying system design.
Salt Rejection Rate
Not Applicable (N/A). This product is a mechanical depth filter that physically intercepts suspended particles. It does not utilize a semi-permeable membrane process to remove dissolved ionic salts. For salt rejection, a downstream system such as a Reverse Osmosis (RO) unit is required, for which this cartridge often serves as the pre-filter.
Pressure Drop
The pleated design aims to achieve a low initial pressure drop. According to technical parameters, the recommended filter change-out is triggered when the pressure differential reaches 2.4 bar (at 20°C). The maximum allowable pressure drop varies with material and temperature, for example, up to 3.4 bar at 82°C for polypropylene (PP) media.
Molecular Weight Cutoff (MWCO)
Not Applicable (N/A). The concept of MWCO is specific to membrane separation processes 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 does not use a thin semi-permeable membrane. Its separation layer consists of thick, porous, pleated media (e.g., PP or glass fiber) designed for depth filtration. Therefore, membrane thickness is not a relevant parameter.
Replacement Cycle
There is no fixed time-based replacement cycle. Service life is determined by operating conditions and the increase in differential pressure. The cartridge should be replaced when the pressure drop reaches the recommended terminal value (e.g., 2.4 bar). The actual cycle depends entirely on the inlet water quality and contaminant load.
Features
High Flow & Extended Life: The large-diameter, pleated design provides high dirt-holding capacity and long service life.
High Filtration Efficiency: Can achieve high Beta ratios (β≥1000) for its rated particle size, indicating ≥99.9% removal efficiency.
Robust Construction: Features include support structures, thickened end caps, and optional handles for easy installation.
Material Versatility: The filter media can be polypropylene (PP) or glass fiber, with various seal materials (EPDM, Nitrile, Fluorocarbon rubber) for chemical compatibility.
Cost-Effective Design: Significantly reduces the number of cartridges and housing units needed, lowering overall system footprint and maintenance costs.
Application Fields
This cartridge is a versatile pre-filter used across multiple industries requiring high-volume particulate removal:
Water Purification: Pre-treatment for RO systems, seawater desalination, and as a security filter.
Power Generation: Condensate water filtration in power plants.
Process Industries: Filtration in the petrochemical, pharmaceutical, food & beverage (e.g., wine, mineral water), and electronics sectors for water, solvents, and process liquids.
Other Applications: Shipbuilding, municipal swimming pools, and paint filtration.
Conclusion
In summary, the HFU660UY1000H (or HFU660UY1000H1) is a high-flow, pleated depth filter cartridge designed for large-scale industrial water pretreatment. Its core value lies in providing reliable protection for downstream equipment through efficient particulate removal, while its design dramatically reduces system complexity and maintenance frequency. It is a critical component for ensuring the longevity and efficiency of precision filtration systems like RO.
