A duplex filter consists of two parallel filter chambers that switch over without interrupting the process flow. Where a simplex strainer requires a process shutdown for cleaning, a duplex filter enables continuous filtration. BÈTA industrie supplies duplex filters for industrial processes in chemicals, water treatment, and the food industry.

With a duplex filter, the filtration process can always continue, even while switching or cleaning the filter element. A smart solution to prevent unplanned downtime and keep processes running smoothly. Thanks to the two independently operating strainer baskets, one filter can remain in use while the other is being serviced.

Our duplex strainers are highly suitable for removing coarser unwanted particles, protecting finer filtration downstream. These filters are widely used across a range of sectors, including the chemical industry, water treatment, and the food and beverage industry.

Our range includes a variety of duplex strainers, available with filtration ratings from 10 mm down to 25 microns. We also offer a range of materials, matched to your process and medium.
