Product Introduction
HFU620UY020H13 is a compact high-efficiency H13-grade pleated filter cartridge, specifically engineered for precision water treatment and critical fluid pre-filtration in space-constrained systems. It adopts polypropylene (PP) as the core filter medium, paired with a lightweight yet durable PP inner support frame and a high-seal EPDM gasket to ensure reliable sealing and structural stability during continuous operation. With a standard outer diameter of 2.5 inches (63.5mm) and optional lengths of 10”, 20”, and 30”, the cartridge features a symmetric pleat design that maximizes effective filtration area while maintaining a compact footprint. Manufactured via cleanroom hot-melt welding, it eliminates adhesive residue and particle shedding risks, complying with FDA food contact standards and ISO 9001 quality requirements. This product is dedicated to removing fine suspended solids, colloidal particles, and microbial contaminants, providing robust protection for downstream precision equipment such as ultrafiltration (UF) modules, small-scale reverse osmosis (RO) systems, and ion exchange resins.
Filtration Precision
The standard filtration precision of HFU620UY020H13 is 20μm, and as an H13-grade filter cartridge, it achieves 99.97% interception efficiency for particles of 20μm and above under rated operating conditions. For customized application needs, it can be tailored to precision levels ranging from 5μm to 30μm, covering fine filtration demands for high-purity process water and coarse pre-filtration for medium-turbidity water. This precise grading capability ensures consistent filtrate clarity across diverse compact water treatment systems, preventing fine particulate abrasion and clogging of core downstream components.
Flux
Flux is a key performance highlight of HFU620UY020H13, optimized for compact systems. Under standard test conditions (25°C, clean water, 1.0 bar operating pressure), the 20-inch length model delivers a stable flux of 10–14 m³/h; the 10-inch model achieves 5–7 m³/h; and the 30-inch model provides 15–19 m³/h. This high-flux performance stems from its hydrophilic PP membrane and optimized pleat density (85 pleats per linear foot), which reduces flow resistance while retaining H13-grade efficiency. Compared with conventional 20μm filter cartridges of the same size, it improves water throughput by 18% without compromising filtration performance, reducing the need for parallel cartridges in medium-flow compact systems.
Salt Rejection Rate
As a particulate H13-grade microfiltration cartridge, HFU620UY020H13 is not designed for desalination, so its salt rejection rate is negligible, generally below 1.2%. Its core function is to remove physical impurities rather than dissolved ionic substances. In integrated water treatment systems, it acts as a critical pre-treatment component, preventing fine colloids and microbes from adhering to RO or nanofiltration membranes, thereby safeguarding the stable high salt rejection rate (98–99.5%) of downstream desalination equipment.
Pressure Drop
The initial pressure drop of HFU620UY020H13 at rated flow and 20°C is only 0.03–0.05 bar, significantly lower than that of traditional H13-grade filter cartridges of the same specification. As impurities accumulate on the membrane surface during filtration, the pressure drop gradually rises. The recommended maximum allowable pressure drop for replacement is 1.8 bar. Maintaining a low pressure drop minimizes system pump energy consumption, reduces pipeline operating stress, and extends the service life of the entire water treatment system.
Molecular Weight Cutoff (MWCO)
Since HFU620UY020H13 relies on particle size-based filtration rather than molecular separation, its molecular weight cutoff (MWCO) is not a core technical parameter and lacks precise calibration. In practical applications, it can roughly intercept macromolecular substances with a molecular weight of 130,000–230,000 Daltons, such as large colloidal organic matter, microbial flocs, and polymer additives. However, it has no interception effect on small-molecular substances like inorganic salts, monosaccharides, and small-molecular organic acids.
Membrane Thickness
The polypropylene filter membrane thickness of HFU620UY020H13 is precisely controlled at 0.10–0.14 mm, a balanced design that balances filtration efficiency, dirt-holding capacity, and water permeability. The thin yet reinforced membrane structure reduces flow resistance to ensure high flux, while the dense PP matrix provides sufficient mechanical strength to resist water flow impact and mild backwashing pressure without deformation or rupture. Additionally, the membrane’s hydrophilic surface reduces hydrophobic impurity adhesion, enhancing dirt-holding capacity and maintaining stable flux during long-term operation.
Replacement Cycle
The replacement cycle of HFU620UY020H13 depends on raw water turbidity, operating flow rate, and system pressure drop, varying across application scenarios. In ultra-clean industrial process water with turbidity below 1.2 NTU, the replacement cycle can reach 3–5 months; in medium-turbidity environments such as pharmaceutical purified water pretreatment or electronics factory process water (turbidity above 10 NTU), the cycle shortens to 0.5–1 month. Once the system pressure drop reaches the recommended 1.8 bar threshold, the cartridge must be replaced immediately, regardless of service time, to avoid efficiency degradation or equipment damage.
