AD051 is a state-of-the-art dust filter unit designed to deliver high filtration power density while adapting to specific dust characteristics. Air enters the filtration area vertically downwards and is distributed evenly across the filter chamber by the inlet baffle.

True Downflow technology, which combines a downflow air pattern with vertical filter elements, forces the separated dust down into the dust disposal solution and ensures that following pulse jet cleaning the dust is directed downwards. The incoming air stream ‘washes’ dust from the vertical filter elements enabling a two-stage cleaning system for optimized efficiency. Vertical filter elements allow this washing due to their orientation – traditional horizontal filter elements can compact dust on the top. Using vertical filter elements also means that the dust that is cleaned from each element is directed straight into the dust disposal solution, not onto filters below as with a horizontal arrangement.

The cartridges can be monitored by a differential pressure sensor that measures the cleanliness of the filter elements and only cleans on demand to ensure optimal filtration efficiency and reduced energy consumption. AD filters can be equipped with a HEPA filtration stage if required, making them suitable for internal air recirculation.
