Advantages of 2 Bag Filter Housing
- 1.Adopting a three-point locking method to achieve sealing, each filter bag is locked separately to prevent side leakage and ensure liquid purity.
- 2.For your filtered liquid, carbon steel/ss304/ss316/Hastelloy material is used to achieve high pressure and corrosion resistance for you.
- 3.You can choose from four opening and closing methods including rocker arm quick opening, flip cover, and concave cover, making it easy for you to replace the filter bag.

The number of fixed filter bags inside the 2 Bag Filter Housing mainly depends on the size of the filter bags you choose to handle the flow rate it can handle. But in practical production applications, the viscosity of your slurry, the accuracy of the filter bag used, and the inlet and outlet pipe diameters will all affect the processing capacity of your filter. The processing flow rate of the 2 Bag Filter Housing under normal circumstances is as follows.
#2 specifications (double bag): Recommended flow rate is 60-80 m ³/h.
#1 specification (double bag): Recommended flow rate is 30-40 m ³/h.
#4 specifications (double bag): Recommended flow rate is 15-20 m ³/h.
The commonly used materials for the 2 bag filter housing of FiltEdge include carbon steel ss304、ss316。 If you have special working conditions, you can contact us to customize the materials.
Our 2-bag filter typically has a pressure range of 0.6-1.0MPa. If your working condition belongs to a high-pressure environment, you can customize a high-pressure resistant 2 Bag Filter Housing with a maximum pressure of 2.5MPa.
The backpack style 2 bag filter housing refers to the liquid inlet and outlet on the same side of the filter, just like a backpack. If your factory space is limited, you can use backpack filters, which can also be used against walls.
