Product Introduction
This product is a high-flow, single open-end filter cartridge. Based on the search results, the HFU660UY200J model and other similar codes (HFU660UY200H4W, HFU660UY200HW) belong to the same series of large-diameter pleated filter cartridges, typically used for industrial water treatment. The core design features a unique crescent-shaped geometric pleating method, which provides a large effective filtration area. The standard filtration direction is from the inside out, effectively trapping contaminants within the cartridge.
Filtration Precision
The filter cartridge can be produced in various filtration precision ratings. Available options typically include 1, 5, 10, 20, 40, and 70 microns, among others. Specifically, for the HFU660UY200J model mentioned, the 200 in the code often signifies a 2-micron (μm) rating, while H1 in the HFU660UY200H1 variant likely indicates a 1-micron (μm) absolute filtration precision.
Flux
This series is characterized by extremely high single-cartridge flow rates. Data for the 60-inch (1524mm) long cartridge shows a maximum flow capacity of up to 204 gallons per minute per pressure differential (gpm/psid), which is equivalent to approximately 772 liters per minute at 70 millibars. Another source suggests a maximum recommended flow rate of up to 1300 liters per minute (LPM).
Salt Rejection Rate
This filter cartridge is a mechanical depth filter, not a reverse osmosis (RO) membrane. Therefore, it does not have a salt rejection function. Its primary purpose is the removal of suspended particles, sediment, and other particulates to protect downstream equipment such as RO membranes.
Pressure Drop
The initial pressure drop is very low, typically around 0.02 MPa. The recommended replacement pressure drop (indicating the cartridge is exhausted) is 2.4 Bar. The maximum allowable pressure drop is 3.4 to 3.5 Bar.
Molecular Weight Cutoff (MWCO)
As a micron-rated pleated filter cartridge, it operates based on particle size exclusion rather than molecular weight separation. Therefore, the Molecular Weight Cutoff (MWCO) parameter, which is standard for ultrafiltration (UF) and reverse osmosis (RO) membranes, is not applicable to this product.
Membrane Thickness
This product does not use a thin-film composite “membrane.” Its core filtration medium is pleated filter material, such as polypropylene (PP) or glass fiber. The thickness is determined by the specific pleated media layer.
Replacement Cycle
The replacement cycle is not a fixed time interval but is determined by the operating conditions and water quality. The key indicator for replacement is when the system’s pressure drop across the filter reaches the recommended replacement value of 2.4 Bar.
Features
High Flow Design: The large diameter (6 inches/152.4mm) and pleated design allow for high flow rates with minimal pressure drop, reducing the number of cartridges and housing size needed.
Cost-Effective: Reduces installation, operational, and labor costs due to fewer cartridges and less frequent change-outs.
High Dirt Holding Capacity: The design increases contaminant loading capacity, extending service life.
No Internal Cage: The “UY” series often features a construction without an internal metal support cage, minimizing waste.
Material Options: The filter media is typically polypropylene (PP), and sealing gaskets are available in various materials like EPDM, Nitrile, Fluorocarbon, and Neoprene.
Sanitary Design: All-polypropylene construction with thermally bonded ends prevents media migration and secondary contamination.
Application Fields
It is widely used as a pre-filter (guard filter) in large-scale industrial water treatment systems, including:
Pre-filtration for Reverse Osmosis (RO) systems.
Pretreatment for seawater desalination.
Filtration of power plant condensate water.
Pre-filtration for high-purity water in electronics.
Filtration in petrochemical, oilfield injection water, and biopharmaceutical industries.
Conclusion
The HFU660UY200H1 (and its series variants like HFU660UY200J) is a high-performance, large-flow depth filter cartridge. It excels in applications requiring high flow rates with low pressure drop and is designed to protect sensitive downstream equipment by efficiently removing particulate matter.
