Description

For more and more strict demand on filtration precision, we developed  welding filter bag . The welding filter bag is made of high-grade polyester and PP felt .The  surface is singed to avoid fiber falling which will cause pollution to the filtrate. The felt is Needle  Punched which could provide three-dimensional filtration. It is called indepth filtration. The  filtrate passes the felt, while the particles is detained in the surface and inside of felt.
  The even thickness, mesh opening, and reinforced mechanical tensile, guarantee the filter bag  a better filtrating efficiency and long lifetime. The welding method can avoid the silicon oil  pollution and side leak caused by pinprick.
  It measure up the technical requirement in industrial areas as electronics field, foodstuff  industry, etc, and gained the License of Foodstuff Certificate issued by the Ministry of Health
  P R C ,China.
  The plastic ring is made of high quality engineering plastic, which is of high physical  performance and chemical causticity-proof ability. With the special treatment, it can be  equipped in almost bag filters in the market. As a part of the filter bag, the handle is higher
  than the filtrate level, which makes high efficiency for replacement.
  The filter material is Polyester or PP, and filtration precision is from 0.5 micron to **0 micron
