Dust Filtration >> Applications  >> Protein industry

One of the largest American chemical companies has Protein plant with a total investment of over USD40 million. They were sourcing for a regular filter bag manufacturer. Compared several companies, they chose ST Filter as their standard filter bag supplier. Not only because ST Filter can provide the same quality bags, but ST Filter has Chinese FDA Certification for food Industrial.
ST Filter chose the same quality and same techniques for bag sewing, which were originally imported from USA.

Advantage

Thermal setting ¡ª gives a stably size for filter bag even the temperature picks up to 150oC.
Singed¨CPrevent the fiber from drop to down stream and gives more microcosmic filter area.
Self-supporting-- Gives more air permeability compares scrim supporting felt and cost saving.
Ground wire ¨C Ground wires stitching along the tube ensure the persistent antistatic ability.

Ground wire, ensure the sustained conductive ability.

Result

The end user ordered 100 pcs of filter bags for trial. And they ordered 500pcs to replace all of the imported filter bags. Now they do not need to import the expensive filter bags from USA.
