Compact unit that creates a vacuum leading to negative pressure in the cavity. Only 6 Bars of air pressure from the injection machine needed. The vacuum can be made thru the clearance of the ejector pins and/or an air valve.
This unit is able to create the Vacuum (60L/min) and blow-off (6bar) through the same channel. Vacuum is produced throughout the injection process. Blow-off is produced during the ejection process.
