In numerous branches of industry and industrial applications, self-cleaning automatic filters have established themselves as process-safe and powerful filter systems of mostly low-viscosity liquids. Reasons therefore are continuous operation, low maintenance requirements and the long service life of the filter media used. Consequently, automatic backflush filters are used, for example, in water treatment (cooling water, process water, building water, wastewater, spraying water, drinking water), in the filtration of seawater, water streams in metallurgical plants and rolling mills, liquid fuels, and water-based and non-water-based cooling lubricants. The highly reliable technology and design of FAUDI fully automatic backflush filters has also been proven in the most challenging environments of numerous offshore installations.

The sizes of the two FAUDI backflush filter series are suitable for very high flow rates depending on the filter medium, the filter fineness and the type of backflushing. A modular design allows individual adaptation of the flow rate in each case from 15 m³/h to 12,000 m³/h. We are able to complement our standard sizes in welded construction as needed with project-specific products using the ideal materials, coatings and controls – all tailored to your use case or the customer specifications, standards and norms required.

How does a fully automatic
backflush filter work?

Filtration

The medium which has to be filtered flows through the filter elements from the inside to the outside and impurities are retained on the inside at the surface of the filter elements. Thereby, the pressure difference between the dirty and clean side of the filter elements increases.

Backflush

RSF F30 with filter elements

If the differential pressure has exceeded a set limit or a time interval has expired, the backflush filter automatically opens the backflush circuit in the cleaning unit. Due to the rotation of the cleaning unit, a partial flow of the filtered product passes through each filter element in turn from the outside to the inside and flushes the impurities from the smooth filter surface by reversing the flow. The backflush medium will be flushed out through a separate connection. During the backflushing process, the actual filtering process is not interrupted.

RSF F32 with filter cylinder

If the differential pressure has exceeded a set limit or a time interval has expired, the backflush filter automatically opens the backflush circuit in the cleaning unit. Compared to the filter element design (RSF 30), in the filter cylinder design (RSF 32) suction is applied locally through a slot in the rotating cleaning unit at a defined surface element of the filter cylinder (sequential backflushing). The backflush medium will be flushed out through a separate connection. During the backflushing process, the actual filtering process is not interrupted.
