What is Multi Bag Filter Housing?
Multi Bag Filter Housing is also known as multiple bag liquid filter vessel or multi-sock filter tank. It is a pressurized industrial filtration unit that can hold 2-32 bags inside, solving your extra large flow rate.
These filter tanks can be configured for coarse pre-filtration or high precision fine filtration in your production line. Depending on your production process, you can choose the required filtration accuracy (1-1000μm) to protect your downstream equipment and improve the quality of your products.
FiltEdge’s rugged Multi Bag filter housing is widely used in the petroleum, chemical, pharmaceutical, water treatment, paint, ink and electronics/semiconductor industries. It handles acidic and alkaline liquids, high flow cooling water and solid particulate contaminants in harsh conditions, ensuring that your filtration quality remains consistent.
