Welding Filter Bag with plastic ring for Liquid Filtration

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 300 micron
