PES folding filter selection of German imported film, bubble point for 0.24-0.3mpa, raw materials in line with GMP and FDA, the choice of ultrasonic hot melt, do not use adhesives. Model: Double head flat pressure type: outer diameter φ70mm inner diameter φ28mm length International General Specification: 10, 20, 30, 40 inches.
Characteristics:PES Folding FilterMembrane as the center of the membrane folding filter, to determine the filter film raw materials, by polypropylene nonwovens (mesh), divided into diversion layer and support folding, insert the central tube, loaded into the shell, all parts are selected without adhesive hot melt welding technology, melt seal composition of intact integrated filter, free of chemical contaminants, product implementation of 100% integrity testing. Endotoxin ≤0.25ev/ml fits in with the American Pharmacopoeia (VSP) specification.
Commonly used Specifications: 5 "10" 20 "30" 40 "Interface type: 215222226M30M36 polyether sulfone Folding Filter (PES): high filtration accuracy, high flow rate, long life, good chemical stability.
Structure: The filter cartridge for double-layer polypropylene discount structure, the inner layer for (pp,ptfe,pes three of one) for the final filtration layer, the outer layer selection of the aperture on the non-woven fabric for the coarse filter layer, played a pre-filtration role, the table bracket for polypropylene or stainless rigid data; Therefore, the filter cartridge is pre-filtration and final filtration combined. Filtration accuracy: 0.10, 0.22, 0.45, 0.65, 0.8, 1, 3, 58 aperture, according to the different requirements of users to choose.

Operating conditions: 20 ℃ When the large operation pressure difference 5bar60℃ when the large operation pressure difference 4bar80℃ The large operation difference 2.8bar high temperature sterilization temperature does not exceed 100 ℃ advantages: Discount structure filtration area is large, starting pressure difference is low, fast flow rate, filter volume is small, cost is small. By so pre-filtration and final filtration into one, so the filter capacity can be larger. The application life is longer than that of a single aperture filter. A single pure polypropylene raw material, easy to judge its chemical compatibility.
Defects: Because of the filter layer paper fold, the working pressure generally can not surpass 0.3MPA, such as beyond the pressure microporous has the phenomenon of expansion, solid easy to wear filter, special working temperature greater than 60 ℃, recoil effect is not ambitious.
Scope of application: PH1-13, Pharmaceutical, food, beverage terminal filtration. Filtration accuracy: 0.10.110.450.65um application temperature: ≤70℃ PTFE Film (PTFE) folding filter: High filtration accuracy, with resistance to high temperature, acid and alkali properties. Scope of application: PH1-14, Pharmaceutical, fine chemical, terminal filtration. Filtration accuracy: hydrophilic 0.220.45 hydrophobic 0.10.2 application temperature: 70-120 ℃.
