PTFE Filter Bag


A highest-end-variety filter bag

What is a filter bag?

Filter bags can be the ideal solution for your industrial filtration application needs. They are designed to remove contaminants and debris from liquids and the dirt is caught inside the bag.

Other filter technologies collect the solids on the outside of the device giving them the potential to dislodge into the filter upon removal. Filter bags keep the clean side of the filter that way, The filter bags remove the amount and size of contaminants depends on their specific micron rating.

What is PTFE?

When it was first created in the early 1940s, PTFE (also known by the brand name Teflon®) soon shown its value in a variety of applications. A PTFE membrane is a layer of material that filters out particles of a particular size and shape while letting other particles pass through.

What is a PTFE filter bag?

When used to produce filter bags, PTFE is the highest-end-variety material. It has great resistance of erosion, so it is suitable for the occasions which require corrosive resistance and long service life.

Brother Filtration polytetrafluoroethylene (PTFE) synthetic fiber filter bag is made of special materials, which can continually operate at 240℃ and sustant all PH range of acid-base erosion at instant 260℃.

The PTFE Filter Bag has excellent self-lubricated ability and can withstand ultraviolet radiation, meanwhile it absorbs no moistures. However, the wear resistance of PTFE fiber filter material is average, so there are stricter requirements for the filter bag frame.

With its above mentioned characteristics, the PTFE filter bag can perfectly applied to industries such as coal-fired boilers, waste incineration, refining and chemical production process, titanium dioxide (TiO2) production process, treatment of flue gas in the production of carbon block and the first time smelting of some metals.


We always want to present the best products to our customers, so we use the highest quality materials to manufacture our filter bags. The PTFE filter bag is one of our best works.
