» PTFE Liquid Filter Bag

The liquid filter bag is a replaceable filter element of the bag filter system. Our bags are made of food-grade nylon material, 8-600 mesh is our best-selling mesh, and liquid filter bags can be customized in size.

And there are a variety of media types for you to choose from, such as polypropylene, polyester, nylon, porous PTFE film and stainless steel, etc.

Characteristics of PTFE

1. It has the characteristics of high temperature resistance, acid and alkali resistance, corrosion resistance and smooth surface.

2. It is suitable for filtration in the acid-base industry, and can be used in the filtration of waste incineration station PH1-14.

3. It can withstand high temperature filtration of 300 degrees, and has a wide range of applications in chemical, pesticide and other industries.

4. It has strong chemical compatibility, benzene, solvents, aromatic hydrocarbons, strong acid solutions, strong alkaline solutions can all be well tolerated.

Double Sewing

The double-layer sewing process will not cause side leakage, which is convenient for cleaning and repeated use.

Single Stitch

During use, there will be no falling off and cutting, which is also conducive to cleaning.
