FDD filters are sediment separators particularly suited to continuously removing such impurities and preventing the formation of deposits, thanks to the option of adding chemical conditioning products from the AZ® range to the system (universal anti-corrosion and anti-scale protectant, universal cleaners for new and old systems, antifreeze, and anti-algae agents).

FDD filters are constructed from AISI 304 stainless steel and can accommodate a special internal PES/PP filter bag (supported by a stainless steel mesh basket), the spacious compartment of which allows for the storage of the necessary chemical conditioners and protective additives.
A 9000/10000 gauss magnet can be inserted inside the filter bag to facilitate the more thorough removal of heavy metal contaminants.
