Application of Sock Filter Housing
FiltEdge’s Sock Filter Housing is widely used in petrochemical, water treatment, food and beverage, fine chemical, automotive manufacturing and other industries. Submit your working conditions and we will make a filtration system program for you.
In food and beverage, resin, paint, ink, and automotive electrophoretic paint filtration. With 1% side leakage of filter media, the finished product will have particulate impurities and become defective.FiltEdge’s Sock Filter Housing utilizes a three-point tight locking design, and a patented double-step sealing structure. It ensures 100% slurry interception, reduces the defective rate by about 15%-30%, guarantees the stability of your finished product batch, and reduces the economic loss caused by rework.
In large scale water treatment, petrochemical, and paper industries. With huge flow and pressure, Sock Filter Housing is easy to burst the bag and cause downstream equipment damage and shutdown. FiltEdge provides CE/ASME thickened filter housing, which passed 1.5 times design pressure test. This ensures that your production line can run smoothly, reducing the failure rate by more than 40%, and avoiding hundreds of thousands of dollars of downtime loss in one day.
In electroplating, pickling, and pharmaceutical intermediate applications. Chemical corrosives can cause damage to housings, environmental penalties, and wasted raw materials. FiltEdge manufactures your Sock Filter Housing using a corrosion-resistant 316L substrate and Viton/PTFE seals. Dramatically extends seal replacement intervals by 30%-50%, ensures 100% leak-free filters, and enables safe production so you can easily respond to local regulatory audits.
