baghouse polyester dust collector bag

Good air-permeability Needle punched craft High quality raw material:PET Acid and alkali resistance Good abrasion resist

1)  PET dust bag is made of PET staple fiber by needling process.

2)  The surface of this product is neat and smooth after certain finish treatment such as heat setting, 

      Singeing, calendaring or coating.

3)  is an ideal filter medium under normal temperature in areas of solid-liquid separation and 

      gas- solid separation and widely used in steel industry, 

      non-ferrous metal, chemistry industry, cement and foodstuff etc.
