1. TIG welding technology of stainless steel and galvanized steel ring. The diameter error is only less than 0.5mm and the horizontal error is less than 0.2mm. The filter bag made of this steel ring is installed in the equipment to improve the degree of sealing and reduce the chance of side leakage.
2. The filter bag is produced by high-speed industrial sewing machine without silicone oil cooling, which will not cause the problem of silicone oil pollution.
3. Filter bag filtration accuracy range from 0.5 micron to 300 micron, the material is divided into polyester, polypropylene nylon and other filter bags.
4. All the labels on the filter bag marked with the product specifications and models are selected in a convenient way to prevent the filter bag from contaminating the filtrate during use.
