Ordinary filter materials include traditional needle punched felt, woven filter materials, etc.
The working principle is the so-called “depth filtration” technology, that is, through the collection of filter material fibers, a “primary dust layer” (i.e. powder cake) is first formed on the surface of the filter material, and then this layer of powder cake is used to filter subsequent dust. dust.
PTFE filter material refers to a new type of filter material formed by compounding a layer of PTFE film on the surface of ordinary filter material.
This layer of film is equivalent to a “primary dust layer”. Material exchange is carried out on the surface of the membrane, and effective filtration can be carried out from the beginning of use.
