KDF-K duplex filters

The KDF duplex filter can be used universally as a coarse and fine filter on the suction or on the pressure side. Filter operation is maintained without interruptions during the cleaning phase. The duplex filter is casted as one and consists of two identical single filters which can be operated alternatively or in parallel via a changeover cock switch device. The single filter consists of a cast body, cover and filter insert. The filter insert is a basket strainer made of perforated sheet metal / perforated plate covered with a mesh made of different materials and mesh sizes. The medium to be filtered enters the filter from above, generally flowing through the insert from the inside outward. Impurities are left in the strainer insert, accordingly.

The KDF duplex filter can be used in pressure and suction modes and is versatile for coarse and fine filtration. It is characterized by continuous filter operation during the cleaning possibility. The filter is compatible with the KSF series. The filter combines the so-called housing sizes (GR) with the various nominal widths (DN) of the flange connection. KDF-K has a bolts and nuts lock and can also bedelivered with screws and nuts as well as with a quick acting lever lock (medium-dependent - risk analysis required). Subsequent on-site retrofitting is also possible.

Brief description and function

The duplex filter, cast as a component, comprises two identical single filters, connected via a cockswitching device to a filter side or can be operated in parallel. Medium to be filtered enters the filter basket from the top and flows through the insert inside out. Dirt thus remains in the filter element. As a special version, the filter is also available with star filters.
