Abstract: A dust suction system for a dry degreasing and deburring machine includes an air suction circuit, a suction fan, a settling chamber provided with a filter cartridge, and an unclogging unit provided for injecting a flow of unclogging air into the filter cartridge during an unclogging operation. The dust suction system includes a control unit that controls the fan and the unclogging unit depending on measurements of pressure and load in the air suction circuit.
