Vacuum Connection

A hose that is suitable for vacuum applications must be connected at the installed hose connection
and secured with a suitable hose clamp. The supply hose must have the same nominal diameter as
the installed connection. The maximum recommended hose length is around 10 meters. A reduction of
the internal hose diameter or the use of longer hoses could impair the functionality of the system.
Vacuum
Once vacuum is applied in a gripper, it immediately begins suction when the cylin-
der is open.
