The EcoCVac, from Dürr Ecoclean offers an effective dry cleaning system that eliminates the need for compressed air. The equipment relies on the newly developed vacuum suction technology. This ensures that contaminants are removed not just from the part but also from the work chamber within 1.5 to 3 seconds of process time, claims the company.
The EcoCVac system comprises a pressure vessel in which a vacuum is maintained permanently. This is connected by a pipe to the vacuum chamber in which the part is placed. Once the chamber is closed, a powerful airflow is directed through it, thereby 'entraining' the chips sticking to the part and taking them into the vacuum vessel.
