The sleeve-filters represent the best rational solution to dust collection as they do not alter its physical status.
They collect atmosphere emissions in compliance with rules and they do not pollute. FFB filters are particularly suiteble to collect dusts from bulk materials discharging inside pit. The length of modules is of 2100 mm. to be coupled between each other till a length of 20m and over.
During product discharging the fan which is placed in the filter upper parto sucks the polluted air. so goes out.
Filtered by sleeves from upper frame through VENTURI pipes (which are placed upstream sleeves).Made in Italy
