The system is designed to filter and collect dust or small pieces of material, in suction during the processing phases of the material itself. It is particularly suitable for the removal of dust from industrial processing. The particulate matter and harmful dust on the workstations are picked up directly through suction pipelines and are conducted inside the filter due to the depression produced by the suction fan. The heavier particles fall directly into the hopper and are then discharged and disposed of in compliance with relevant regulations The lighter particles are filtered through bag filters in the upper part of the filter. The purified air is therefore released into the atmosphere.
