The large-flow filter element is also known as the high-flow folded filter element. Compared with traditional filter elements, the large flow filter cartridge has comprehensive advantages such as large flow rate, wide effective filtration area, high pollutant retention capacity, low pressure loss, and simple disassembly and maintenance. The product adopts an external-inlet and internal-outlet gradually varying pore size folded structure. The surface layer is dense to intercept impurities, and the inner layer is loose to guide the flow of fluids. This can effectively delay the rate of filter material clogging. The high flow pleated filter cartridge is suitable for various industrial water treatment, pure water preparation, and multiple types of fluid filtration conditions, and is the core supporting consumable of large-scale filtration systems.
1. Core technical parameters
1. Physical structure specifications
The industry standard outer diameter is 152mm, while the only niche custom-made model has an outer diameter of 115mm. The mainstream market is divided into three length specifications, covering various application scenarios forhigh flow water filter cartridge: 20 inches (508mm), single branch rated flow rate of 30-50m³/h, suitable for small water purification equipment, laboratories, and auxiliary filtration systems; 40 inches (1016mm), single branch rated flow rate of 60-80m³/h, with an effective filtration area of up to 3.5-6㎡, with extremely high adaptability, becoming the universal standard for industrial projects; 60 inches (1524mm), single branch rated flow rate of 90-110m³/h, specially for large centralized water treatment and large-scale water supply projects. Thelarge flux filter cartridge is composed of filter material, reinforced supporting framework, and sealing end cover, with a rigid overall structure that can be stably used in continuous operation conditions.
2. Filter accuracy grades
This product has standardized filtration accuracies ranging from 1μm to 100μm. Based on its filtration performance, it can be classified into two major specification grades for the high flux filter cartridge: the nominal precision type filter element has an impurity retention efficiency of approximately 90%, which can meet the pre-treatment requirements of various filtration systems; the absolute precision type filter element has a β value of ≥1000 and a solid impurity retention rate of up to 99.9%, and is suitable for various high-demand precision filtration conditions.
Precision matching suggestions: 1-5μm are suitable for electronic ultra-pure water, biopharmaceuticals, and food and beverage terminal precision filtration oflarge flow filter cartridge; 10-20μm are mostly used for reverse osmosis pre-protective, industrial circulating water, and equipment cooling water in conventional fluid systems for high flow pleated filter cartridge; 40-100μm are suitable for the front end of pipeline primary filtration, mainly to intercept large-sized solid impurities such as sand and suspended particles with cost-effective high flow water filter cartridge.
3. Flow and pressure difference performance
The flow and pressure difference parameters are based on the test results under a constant temperature of 25℃ and a reference pressure of 0.2MPa. The initial operating pressure loss of the new large flux filter cartridge is ≤ 0.02MPa. The low resistance characteristic can effectively reduce the pump load and reduce system energy consumption costs. Under normal temperature conditions, the maximum allowable working pressure difference of the high flux filter cartridge is 0.24-0.34MPa; affected by temperature, the medium temperature increase will weaken the structural pressure resistance performance, and the safe pressure resistance upper limit in high-temperature conditions is 0.2MPa. Industry standard replacement threshold: when the operating pressure difference rises to 0.24MPa, it indicates that the pollutant retention capacity of the large-flow filter element has approached saturation, and it is necessary to replace the large flow filter cartridge in time to prevent constraining system flow and reducing filtration quality. In addition, the viscosity of the medium and the flow capacity are negatively correlated. When the viscosity of the liquid doubles, the actual flow capacity of thehigh flow pleated filter cartridge will decrease by approximately 30%.
