Description
Industrial Duplex Strainers are dual-chamber filtration units designed for applications requiring continuous flow during basket cleaning or maintenance. They consist of two parallel strainer housings connected by a diverting valve or manifold, allowing seamless switchover between chambers without process shutdown. These strainers are ideal for critical systems in industries where downtime is costly.
