11.1

 

FMHD with separating cylinder and blow-off function 

 

Optimum flowing compressed air pressure 6.0 bar 

 
 
 
 
 

 
Before initiating the blow-off pulse, ensure that the gripper (with attached workpiece) is not pressed 
against a solid surface. The workpiece must be able to freely detach from the gripper. 
 

 

 

 

Maximum overpressure 

The maximum overpressure in the gripper (vacuum reservoir or valve chamber) 
must be limited to a maximum of 0.2 bar. For example, no continuous blow-off pulse 
as long as the gripper is placed on a workpiece in the waiting position, or similar.
