Built 2016. The NF automatically discharged horizontal disk kieselgur filters are suitable for filtering beer and 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 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.
