NF automatically discharged kieselgur filters

The NF automatically discharged horizontal disk kieselgur filters are suitable for filtering wines and lees, and they are particularly effective in brightening and finishing processes. Filtering with kieselgur is a very widespread practice in the winemaking world, and Della Toffola’s exclusive horizontal disk system has been adopted by thousands of wineries all over the world. The NF filters are perfect for filtering operations on large amounts of liquid with low percentages of solids in suspension because they combine very rapid working times with excellent filtering results. This type of filter relies on a unique system that keeps the filter cake intact even in the case of accidental interruptions in the filtering process. The centrifugal discharging of the cake also makes the emptying and cleaning operations quick and easy, and servicing procedures also take up very little time because the filter’s structure has been designed to facilitate these activities to the utmost. The filters are made in compliance with the 97/23/EC PED. All the filter parts are made of  AISI 304 stainless steel, while the reduction units and electric motors are protected with an acid-proof epoxy-based paint. Models from 5 to 50 m².
