• Air flow: 16.000 m³/h
• Filter type: Cartridge filter AIRCOMPACT ATEX
• Fan: PR 500/2 – 18.5 kW

General description

For the extraction and the removal of dust developed during production, a system was built as follows: two suction benches, 4 meters in length each are arranged in series, with the aim to remove the pollutant directly during the grinding operations.

The benches are connected to a main pipeline, which conveys the pollutant to AIRCOMPACT cartridge filter, ATEX version, with  compressed air self-cleaning: the polluted air is then drawn in through the inlet chamber connected to the hopper. The dust, due to the considerable decrease in speed, will precipitate in the collection container and subsequently is conveyed to the filter cartridges passing from outside to inside thus depositing the impurities and returning the purified air. During the operation, the filter is kept perfectly efficient, through a counter-current cyclic cleaning system. The filter is also provided with safety panels: this protection allows to put explosion in direction of one safety area. The necessary depression of the entire circuit is guaranteed from a high performance centrifugal fan , which has the additional function of bring filtrated gas into the atmosphere through chimney.
