Bag Filters

The DUOLINE™ Bag Filters are designed for liquid filtration applications that cannot be shut down for filter bag change-out.

The DUOLINE™ Bag Filters are designed for liquid filtration applications that cannot be shut down for filter bag change-out. These applications include batch process and continuous flow applications in a variety of industries. The bag filter consists of two, double length size, single bag filter housings linked together with a special ball valve or butterfly valve flow switching system. When the bag in one filter housing requires changing, the flow can be diverted to the other housing by opening and closing the valves. The system flow is designed to never shut down.
