Tailor made customized solutions The KDF-VB duplex filter can be installed in pressure and in suction line
and is versatile for coarse and fine filtration. It is characterized by
continuous operation during the cleaning phase. The duplex filter comprises two
identical single filters connected via a valve-switching device with butterfly
valves, which can be switched to only one filter body or can be operated in
parallel.















Each single filter consists of a cast or welded body, cover and filter
insert. The filter insert is a basket strainer or ring type strainer made of
perforated plate covered with a stainless steel mesh. The 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.
