Self-cleaning filter for dust treatment
The cartridge filter dust collector is a self-cleaning mechanical filter used to separate particulate matter contained in an air stream to be treated.
This technology is suitable for powders of different granulometry and, thanks to compactness of cartridges, it is used in industrial contexts characterized by reduced spaces.
The polluted air stream enters the lower part of the dust remover and passes through a pre-filtering chamber that allows coarse dust to precipitate, protecting the cartridges from excessive loads.
The flow, then, reaches the cartridges and passes through them realizing consequently the separation of particulate matter that stops on the filtering media surface.
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.
The following table shows main cartridges technical variables:
Diameter | Height (H) | Application field | Features | |
Cartridges for fine dust | From 125 to 156 mm | From 600 to 2000 mm | Fumes and powders from laser and plasma cutting processes and welding fumes in general… | Contained filtering surface, wide folds |
Cartridges for medium-fine dust | From 218 to 230 mm | From 600 to 2000 mm | Cement, wood and minerals processing… | Filtering surface and folds are sized according to the powders |
Cartridges for coarse dust | From 300 to 350 mm | From 600 to 1500 mm | Shot blasting, metalworking, powder coating | High filtering surface, thin folds and compactness |
