TIANYUAN Filter Bags

The filter bags we can provide:

1. dust collect filter bags: we can provide polyester needle felt filter bags, antistatic needle felt bags, water-oil repelled needle felt filter bags, Aramid (Nomex) needle felt filter bags, PPS needle felt filter bags, P84(PI) needle felt filter bags, PTFE needle felt filter bags, fiber glass needle felt filter bags, fiber glass wove filter cloth filter bags, FMS needle felt filter bags, besides, we also can provide some mixed material filter bas for some special usage.

2. liquid filter bags: we can provide polyester, polypropylene and polyamide filter press filter bags, centrifuge filter bags or other wove filter cloth filter bags. Beside, we adopt some special polyester and polypropylene fiber to make the nonwoven filter bags for liquid filtration, the precision from 0.5 micron to 200 micron.

3.we provide various of mesh filter bags.

The ring and the sewing method can be customized.

The Features about our filter bags:

       1) Can filter normal temperature or high-temperature gas including corroding gas mixed with acid and alkali, water, oil.

       2) Widely used in metallurgy, chemical industry, building materials, smelting, generating electricity, pottery, machinery, mine, petroleum, dyestuffs, food, grain processing.

       3) Ideal medium to separate liquid from solid or purify gas.

The new workmanship of filter bags making in our factory:

weld joint:

The propertity for  welding bags:

     1.In traditional thread sewing method, to avoid the thread breaks during constant working, silicon oil is commonly used to lower the temperature on sewing thread. The silicon oil will cause the second pollution to filtrate , while 100% welding method can avoid this situation, because there is no need of thread and silicon oil.

    2.Because there is no pinprick, so there is no side leaking. This makes filtration without any leak.

    3.In traditional thread, sewing bag, at the top, there will be protrusion, which is composed of two layers of filter cloth. This protrusion will lead the side leaking at the top, and the filtrate will go to the backward position of the bag. This will influence the efficiency of filtration. The welding bag has a much lower protrusion, which can avoid the side    leak.

   The precision rang of welding filter bag is from 0.5 micron to 300 micron. The material could be Polyester and Polypropylene. The top is with stainless steel ring, galvanized steel ring, or Polypropylene ring.

   The high quality of stainless steel ring and galvanized ring    make it is possible to reduce the diameter tolerance under    0.2mm and horizontal tolerance under 0.2mm. This can    lower the possibility of side leaking
