The changeover valve allows Duplex filters continuous operation even during the cleaning phase. Duplex filters are primarily used in applications where service shutdowns are not practical or they are uneconomical. The SAB product portfolio covers Duplex filters for almost every application! With our wide range of products, we are able to filter liquids and gases. From cast Duplex filters (in stock) for water applications, to welded filters certified with TÜV or any other third party approval for highly aggressive fluids.

Duplex Filter
F101
The Duplex Filter F101D is a multi-purpose filter for liquid media. It is characterized by continuous operation during the cleaning phase as well as a high degree of filtration down to very low microns. As a special feature the maintenance and strainer access can be optimized by choosing different filter cover solutions.
The degree of contamination can be optionally monitored with various differential pressure indicators. Further options, for example magnetic inserts or the sacrificial anode enable an application-specific customization.
