III. Five Structure Types for Precise Matching of Diverse Filtration Conditions
Not all pleated filter cartridges are universal! Based on requirements such as filtration rating, dirt holding capacity, pressure resistance, application scenarios and backwash capability, our filter cartridges are categorized into five types: A, B, C, D and E. Select the right model according to your needs to avoid unnecessary costs and compromise on operating conditions.
???? Type A｜General Basic Grade
It adopts a conventional inner and outer support cage structure. Raw materials undergo strict quality inspection. Featuring a stable overall structure and balanced strength, it delivers high cost performance. Suitable for most general basic filtration applications, it is the preferred standard cartridge for industrial basic filtration.
???? Type B｜High Pressure & High Dirt Holding Type
Equipped with upgraded thickened inner and outer support cages, it achieves a 30% improvement in overall pressure resistance for more stable equipment operation. Featuring a multi-layer gradient filter media structure, it greatly increases the dirt holding area. Suitable for working conditions with high impurity content requiring long-term filtration, it effectively extends the service life of the filter cartridge.
???? Type C｜High Flow & Backwashable Type
Fitted with imported flow guide layer and multi-layer composite filter membrane, paired with thickened pressure-resistant support cages, it features high flow rate, zero fiber shedding and repeated backwashing capability. With high cleanliness and outstanding stability, it is widely used in food, beverage, electronics and other industries demanding high water purity.
???? Type D｜High-End Precision Filtration Type
It is available with a variety of high-end filter media including PES, PTFE, PA6, PA66 and PVDF. Manufactured in a Class 100,000 cleanroom and thoroughly rinsed with 18 MΩ ultra-pure water, every filter cartridge undergoes integrity testing. Free of contaminants, it offers high precision and exceptional stability, engineered exclusively for high-end precision filtration applications.
???? Type E｜For Non-standard Vessels
It comes with three dedicated integral outer support cage sizes: 60, 80 and 130. Purpose-built to solve filter cartridge matching challenges for various non-standard filter vessels and custom tanks, eliminating the trouble of unavailable compatible cartridges for non-standard equipment.
