A filter bag is a device used for filtering and separating solid particles or liquids. According to different application requirements, there are many different types of filter bags to choose from. The following are some common types of filter bags, introduced by filter bag manufacturers:

Bag filter: Made of different types of fabrics, you can choose different fabric materials according to your needs, such as polyester, polypropylene, cotton fiber, etc. Suitable for a variety of applications from particulate to liquid filtration.

Needle felt filter bag: It is made of multiple layers of fibers and has high filtration efficiency and dust holding capacity. It is often used in industrial fields, such as particle filtration in cement, metallurgy and other industries.

Nylon mesh filter bag: Made of nylon mesh, it has the characteristics of high temperature resistance and corrosion resistance. Commonly used in liquid filtration, such as food, chemical industry and other fields.

Filter bag with splint: There are splints on both sides of the filter bag, which can be used for special shape filter equipment. Suitable for some filtering needs that require a fixed shape.

Activated carbon filter bag: Add adsorbents such as activated carbon to the filter bag to remove odors, pollutants, etc. in the gas.

PTFE membrane filter bag: Adding polytetrafluoroethylene (PTFE) membrane to the surface of the filter bag provides higher filtration efficiency and corrosion resistance, and is suitable for some environments with special requirements.

Metal mesh filter bag: Made of woven metal wire, it has the characteristics of high temperature resistance and corrosion resistance. It is suitable for filtering high temperature, high pressure and corrosive gases.

Paper filter bag: Made of paper material, suitable for filtering low-viscosity liquids, such as food, medicine and other fields.

Microporous membrane filter bag: Adding a microporous membrane on the surface of the filter bag material can be used to filter fine particles, such as medicine, electronics and other industries.

The above are just some common types of filter bags. In actual applications, there are more variants and customization options depending on factors such as filter media, particle size, temperature, pressure, chemical properties, etc. When selecting a filter bag, it is necessary to consider the application requirements and consult with a professional supplier or engineer to ensure that the appropriate type of filter bag is selected.
