PTFE bag filters, also known as integrated filters or disposable filters, have various significant characteristics and a wide range of application fields. The following is a detailed analysis of PTFE bag filters:


1、 Product Features


Excellent material quality:


Shell: It is usually made of polypropylene (PP) material, which has excellent chemical stability and mechanical strength, can withstand the erosion of various chemical substances, and ensure the structural strength of the filter.


Filter cartridge: The internal filter cartridge is made of polytetrafluoroethylene (PTFE) material, which is known for its excellent chemical inertness, high temperature resistance, low temperature resistance, corrosion resistance, and other characteristics, making it an ideal filter material.


High filtration accuracy: PTFE bag filters offer multiple pore size options, which can be configured according to different filtration needs to achieve high-precision filtration effects. Its filtration accuracy range is usually between 0.1-10 μ m, which can effectively remove small particles, impurities, and microorganisms in the fluid.


Compact structure: The bag filter adopts a compact integrated design, with a sturdy appearance and low retention capacity, reducing the need for installation space. At the same time, its disposable filter structure does not require a filter cartridge device, simplifying the operation process and reducing the risk of splashing and leakage.


Easy to install and maintain: Capsule filters are easy to install and usually connected to piping systems through threaded connections. The replacement of the filter element is also very simple and fast, reducing maintenance costs and time.


High temperature resistance and chemical corrosion resistance: Due to the use of materials that are resistant to high temperatures and corrosion, PTFE bag filters can maintain stability and durability in harsh working environments. This makes it particularly suitable for handling high-temperature fluids and corrosive media.


High pressure sterilization capability: This filter supports high-pressure sterilization treatment, which can meet strict hygiene requirements while ensuring filtration efficiency.


2、 Application Fields


PTFE bag filters are widely used in various industries, including but not limited to:


Chemical industry: used for filtering solvents and corrosive solutions.


Biopharmaceuticals: Used for liquid filtration in biopharmaceuticals, laboratory filtration, and other applications.


Food industry: Used for filtering solvents and medicinal liquids in the food production process.


Optical storage industry: used for dye filtration in CD-R and DVD-R production.


LCD production: used for filtering photoresist.


Semiconductor manufacturing: plays an important role in processes such as photoresist technology, grinding fluid filtration, and lithium battery electrolyte filtration.


Air and gas filtration: serving as a pre filter for reverse osmosis and gas filtration, as well as a vent filter for air and gas.


PTFE bag filters are favored by the market for their excellent material, high-precision filtration effect, compact structure, and wide range of applications. It plays an important role in various industries such as chemistry, biomedicine, food, optical storage, LCD production, and semiconductor manufacturing. With the continuous advancement and innovation of technology, the performance and application fields of PTFE bag filters will continue to expand and improve.
