PTFE filter element is also called PTFE filter element and fluorine membrane filter element. Its filter medium is hydrophobic PTFE microporous membrane.
Main characteristics：
Strong hydrophobicity, higher resistance to water erosion than ordinary polyvinylidene fluoride filter membranes
Shock Resistance, Back Pressure Resistance and Repeated Steam High Temperature Sterilization
100% interception of bacteriophages, bacteria and particulates above 0.02 um for gas filtration
It is composed of polytetrafluoroethylene and polypropylene by hot melting. Non-bonding, no falling off, clean and stable, suitable for pharmaceutical industry with strict standards
Introduction of parameters：
Polytetrafluoroethylene (PTFE) Folding Filter Core-High Temperature Gas Degerming Precision Filter Core
Specification: Conventional 10-40 inches, special customizable. The outer diameter is about 60MM, and the inner diameter depends on the interface mode.
Interface: 226; 222; 224; 220; 215; Flat pressure type; Fin type; Three-piece type; Melt blown plug.
Accuracy: 0.02-70 um
Testing: According to the national GMP requirements, each filter element was tested for water integrity at 23 C.
Pressure difference: forward 4.2 bar; reverse 2.1 bar
Filtration area: > 0.55_per 10 inches
Working temperature and pressure difference:
Type C < 95 ~C Pressure Difference 1bar--Imported Polypropylene and Stainless Steel
Flow: 0.5 M³ calculated every 10 inches
Selection of appropriate filter element instructions:
1: Really need to use PTFE filter element occasion, mainly because the filter element has: high temperature resistance, sterilization, acid resistance, alkali resistance function.
2: This filter element can be divided into two kinds of air and liquid filters, the material is hydrophobic and hydrophilic, and there is an appropriate price gap.
3: Real PTFE filter element, the quality mainly depends on the quality of the membrane, there are imported membranes, there are domestic membranes, and now the domestic standards are not strict. If you see that the customer's use requirements are not strict, there is an individual dealer driven by the price interests, will use other cheap materials to replace, such as N66 (nylon membrane), so that it can also be replaced in a short time. To use.
4: Industry characteristics: high temperature, sterilization, acid-base industry, especially medicine, sulfuric acid and other industries.
