Product Introduction
The HFU660UY200H13W is a high-flow, single open-end pleated filter cartridge designed for industrial water pretreatment. It is part of a large-diameter series, where the code “660” typically indicates a 6-inch outer diameter (152.4mm) and a 60-inch (1524mm) length. This product is commonly used as a pre-filter or “guard filter” to protect critical downstream equipment like reverse osmosis (RO) membranes by removing particulate matter.
Filtration Precision
The filtration precision is typically denoted by the numerical part of the model. For this series, “200” often corresponds to a filtration rating of 2 microns, while the suffix “H13” commonly specifies the precision grade within that rating. Based on similar product listings and industry conventions, “H13” likely indicates a 1-micron (absolute or nominal) filtration precision. It is crucial to consult the official manufacturer’s data sheet for the definitive micron rating.
Flux
This series is engineered for very high flow rates. For the 60-inch length variant, a single cartridge can handle flow rates up to 204 gallons per minute per pressure differential (gpm/psid), which is equivalent to approximately 772 liters per minute at 70 millibars. Other sources suggest a maximum recommended operating flow rate for similar large-flow cartridges can be as high as 1300 liters per minute (LPM).
Salt Rejection Rate
This parameter is Not Applicable (N/A). The HFU660UY200H13W is a mechanical depth filter cartridge, not a semi-permeable membrane used in processes like reverse osmosis (RO) or nanofiltration (NF). Its primary function is to remove suspended solids based on particle size, and it does not have the capability to reject dissolved salts or ions.
Pressure Drop
The initial pressure drop for a new, clean cartridge of this type is very low. The key operational parameters are:
Recommended Replacement Pressure Drop: 2.4 Bar. This indicates when the cartridge is considered loaded with contaminants and should be replaced.
Maximum Allowable Pressure Drop: Typically between 3.4 to 3.5 Bar.
Molecular Weight Cutoff (MWCO)
This parameter is Not Applicable (N/A). MWCO is a specific parameter used to characterize the separation capability of ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) membranes, which separate solutes at a molecular level. This pleated cartridge operates solely on the principle of mechanical particle size exclusion.
Membrane Thickness
This product does not utilize a thin-film composite “membrane” in its construction. Its filtration is performed by a pleated media, typically made of polypropylene (PP) or glass fiber. The thickness and specific structure are determined by the chosen pleated media layer and its design for depth filtration.
Replacement Cycle
The replacement cycle is not based on a fixed time interval but is condition-based. The cartridge should be replaced when the differential pressure across it reaches the recommended replacement threshold of 2.4 Bar, signaling it is fully loaded. The actual service life depends entirely on the inlet water quality and operating conditions.
Features
High Flow with Low Pressure Drop: The large 6-inch diameter and optimized pleated design (often described as a unique crescent or geometric fold) provide a large filtration area, enabling high flow rates while maintaining a low initial pressure drop.
High Dirt Holding Capacity: The design maximizes contaminant loading, extending service life and reducing change-out frequency, which lowers operating costs.
Material and Sanitary Design: The filtering media is typically polypropylene (PP). The construction often features thermally bonded, all-polypropylene ends to prevent media migration and avoid secondary contamination.
Structural Options: Some variants in this series come with an internal support skeleton for enhanced pressure resistance, while others feature a cage-less (“UY”) design to minimize waste.
Customization: Available in various lengths (20″, 40″, 60″) and with different sealing gasket materials (e.g., EPDM, Nitrile).
Application Fields
This filter is widely used as a pre-filter in large-scale industrial water treatment systems across multiple industries:
Power Industry: Condensate water filtration.
Desalination & RO Systems: Pretreatment and RO membrane protection.
Biopharmaceuticals: Process water and raw material filtration.
Microelectronics & High-Purity Water: Pre-filtration for ultrapure water systems.
General Industry: Pre-treatment in petrochemical, food & beverage, and painting processes.
Conclusion
The HFU660UY200H13W is a high-performance, large-flow depth filter cartridge engineered for robust particulate removal in demanding industrial applications. Its core advantages are exceptional dirt holding capacity, the ability to deliver high flow rates with minimal pressure loss, and cost-effective operation through extended service life. It serves as a critical first line of defense in protecting sensitive and expensive downstream equipment.
