Product Introduction
The HFU660UY045HW is a high-flow, single-open-end, pleated filter cartridge. It features a large-diameter design without a center core, employing an “outside-in” flow pattern. This design maximizes filtration area, allowing for high dirt-holding capacity and extended service life, which reduces the number of cartridges needed and overall system footprint in industrial applications.
Filtration Precision
The standard and most common filtration rating for this model is 5 microns (µm). It utilizes high-quality polypropylene (PP) media designed for consistent and reliable particulate removal.
Flux
This model is engineered for high single-cartridge throughput. For the standard 20-inch (508 mm) length, the nominal flow rate is approximately 660 liters per minute (LPM), or about 110 cubic meters per hour (m³/h).
Salt Rejection Rate
Not Applicable (N/A). This is a depth filter cartridge designed for mechanical separation of suspended solids. It does not remove dissolved salts or ions; therefore, it has no salt rejection capability.
Pressure Drop
Initial Pressure Drop: Engineered to be low, thanks to its optimized pleat geometry and large surface area.
Maximum Recommended Differential Pressure: The cartridge should be replaced when the pressure drop across it reaches 2.4 bar (35 psi) at the standard test conditions (typically 20°C water).
Molecular Weight Cutoff (MWCO)
Not Applicable (N/A). MWCO is a characteristic of membrane processes like ultrafiltration (UF) or nanofiltration (NF). This cartridge operates on a micronic (size-based) filtration principle and does not separate molecules by their weight.
Membrane Thickness
Specific membrane thickness is not a primary published specification for pleated cartridges. The focus is on the filter media material (Polypropylene) and its pleated structure, which provides depth filtration and high contaminant loading capacity.
Replacement Cycle
The service life is not time-based but is determined by the increase in differential pressure caused by accumulated solids. The cartridge must be replaced when the differential pressure reaches the maximum limit of 2.4 bar. The actual cycle depends entirely on influent water quality and system operating hours.
Features
High Flow Rate: A single cartridge can handle large flow volumes, simplifying system design.
High Dirt-Holding Capacity: The deep pleats provide substantial capacity for particulate retention.
Broad Chemical Compatibility: The inert polypropylene (PP) media is resistant to a wide range of chemicals.
High Filtration Efficiency: For its rated particle size, it can achieve high Beta ratios (e.g., β≥1000 for 5µm), indicating ≥99.9% removal efficiency.
Cost-Effective: Reduces housing, manifold, and labor costs due to fewer cartridges required.
Application Fields
This cartridge is a standard choice for industrial pretreatment, including:
Guard Filtration for Reverse Osmosis (RO) and Ultrafiltration (UF) systems.
Pre-filtration for seawater desalination plants.
Condensate polishing and general process water filtration in power generation.
Process water and utility water filtration in chemical, pharmaceutical, food & beverage, and microelectronics industries.
Conclusion
In summary, the HFU660UY045HW is a high-performance, 5-micron pleated depth filter cartridge. Its primary role is to provide reliable, high-flow-rate protection for downstream equipment by removing suspended particles. Its design prioritizes long service life, low operational pressure drop, and cost-effective system integration.
