DUOLINE multi-bag filter housings are designed with two single bag filter housings fitted together at the inlet and outlet by a butterfly valve or ball valve. This increases flow capacity and allows the filtration process to run continuously even during filter bag change-outs.
Key DUOLINE bag filter applications:
For Continuous and High Flow Rate Applications
An integral valve linkage assembly is available for DUOLINE bag filter housings with butterfly valves that permits operation of the valves with a single handle.
DUOLINE bag filter housings are available in carbon steel or stainless steel for size 02 (double length) filter bags. End connections are either 2" or 3" flanged.
