Duplex basket-type strainers are built for continuous flow applications where cleaning shutdowns are not permitted. The duplex system allows the flow to be switched back and forth between two filter vessels, allowing one side to be serviced while the other is in use. Duplex basket strainers provide protection for mechanical equipment by straining foreign matter from the connected piping system, reducing overall operating costs.
