Duplex Filters

Duplex basket filter & strainer permits continuous operation because flow can be switched back and forth between two filter
sections. This allows one side to be serviced while the other is in use. Normally duplex basket filters are separated with three
way ball valves or two way ball valve/ butterfly valve connected with equalization tee, between two baskets filter housing.

Operation of Duplex filters

Unfiltered liquid enters the basket housing and passes down through them. Duplex Basket filters & strainers are normally supplied with nut/bolt arrangement at the top of filter element. This will ensure any type of bypassing & confirm the position of basket, even in case of reverse flow. Fluid bypass around the basket is prevented by an optional O’-Ring seal between the basket rim and the housing inside diameter. The valves provided along with the assembly make sure you get intermittent operation.
