Alphafilter HDF filters are designed for ease of use and simplicity. All HDFs are designed to be highly sanitary and easy to clean. HDF filters are composed of a filtering chamber and complementary components, which work together for operations such as pre-coating, filtration with continuous addition of regulated quantities of diatomaceous earth, cake discharge by manual tipping and removal of the bell housing and lastly, the final rinsing of the filtering elements.
