Dust collected by the cartridges precipitates down to the lower part of the filter where hoppers conveys it to collection system (cochlea, rotary valve…). The filtering surface media is kept clean thanks to automatic air cleaning cycles that are usually made in reverse direction. The process is managed on the basis of filter pressure drop, in order to limit the compressed air consumption and to increase lifetime of filtering elements. Cartridges with thin folds and a high filtering surface are cleaned using a rotating nozzle system.
Cartridges are made with different materials, diameters and heights so can be selected according to end-user’s technical needs.
