Ejectors with four, five or six independent vacuum circuits maintain the vacuum level of each circuit even though the other circuits do not have contact. The built-in blow off releases objects distinctly in all circuits simultaneously.
Air operated blow-off
The blow-off signal activates the blow-off function by closing the exhaust port, reversing the supply air fast and distinct to all vacuum circuits. Several ejectors in series can be connected to one common blow-off signal.
