Product Introduction
The HFU660UY045J is a large-diameter, pleated depth filter cartridge widely used in industrial water treatment. It is designed to handle very high flow rates in applications requiring the removal of suspended solids. This cartridge is known for its compatibility with many foreign filter brands, such as PALL.
Filtration Precision
The cartridge supports a wide range of standard filtration ratings, typically from 1 μm to 100 μm. The specific filtration rating is often represented by the last part of the model number; for this “045” model, the standard rating is 5 μm.
Flux
A single cartridge can handle a very high flow rate, significantly reducing the number of filter housings needed in a system. The rated flow depends on its length:
20-inch (508 mm) length: Maximum recommended flow of 660 liters per minute (LPM) or approximately 110 m³/h.
40-inch and 60-inch lengths are also available, offering proportionally higher flow capacities.
Salt Rejection Rate
Not Applicable (N/A). This is a mechanical, depth-type filter designed to remove particulate matter. It does not remove dissolved salts or ions. For salt rejection, a Reverse Osmosis (RO) membrane system would be required downstream.
Pressure Drop
Operating Pressure Drop: Engineered to have a low initial pressure drop due to its large, pleated design.
Replacement Indicator: The cartridge should be replaced when the differential pressure across it reaches 2.4 bar at 20°C.
Molecular Weight Cutoff (MWCO)
Not Applicable (N/A). The concept of MWCO is specific to membrane separation processes like Ultrafiltration (UF) or Nanofiltration (NF), which separate molecules by size. This cartridge operates on a micronic rating system based on particle diameter.
Membrane Thickness
This parameter is not specified for pleated depth filter cartridges. The focus is on the filter media material (Polypropylene – PP) and its pleated structure, which provides a large surface area for particulate retention and depth loading.
Replacement Cycle
There is no fixed time-based replacement cycle. The service life depends entirely on the contaminant load of the incoming water. Replacement is triggered when the pressure drop reaches the maximum recommended limit of 2.4 bar.
Features
High Single-Cartridge Flow: Reduces system footprint and complexity.
High Dirt-Holding Capacity: The pleated design offers extended surface area for longer service life.
Chemical Compatibility: Made from polypropylene (PP), which is chemically resistant.
High Filtration Efficiency: Can achieve a high Beta ratio (e.g., β≥1000 for its rated particle size), indicating 99.9% or higher removal efficiency.
Structural Integrity: Features a reinforced design with a support skeleton and secure O-ring seals to prevent bypass.
Application Fields
It is a versatile cartridge used for prefiltration (guard filtration) in numerous industries:
RO System Protection: Safeguarding reverse osmosis membranes from particulate fouling.
Power Generation: Condensate polishing in power plants.
Desalination Pretreatment.
General Industrial Process Water: Food & beverage, pharmaceuticals, chemicals, electronics, and petrochemicals.
Conclusion
The HFU660UY045J is a high-performance, high-flow depth filter cartridge. Its primary role is to provide reliable mechanical protection for downstream equipment by efficiently removing suspended particles. Its design prioritizes long service life, low pressure loss, and cost-effective system design in large-flow industrial applications.
