Detailed Product Description

We provide high quality plastic ring welded filter bags, welded seam filter bags, steel ring welded filter bags, steel ring stitch filter bags which used for solide-liquid saparation, and air or fume filtration in many circumstances.


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 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.
