■
Single unit
The sizes of the each port are as follows. (Refer to Application and Operating Pressure Range on
.)
■
Manifold
Manifold ports are common at the end plate. Port description and application are the same as the single unit.
Refer to the number of stations that can operate simultaneously for each ejector size on
. If one side
is not used for air supply, plug the unused port or change to the dedicated port plug as shown below.
There are 4 types of port combinations depending on the manifold port specification.
When PS = PD, the common PS/PD ports on the end plate are used, PS port is equipped with One-touch fitting
and PD port is plugged at the time of shipment from the factory. Since the PS and PD are connected inside the
end plate, common supply location can be changed by exchanging the One-touch fitting and the plug.
When PS ≠ PD, PS and PD are not connected inside the end plate. (It is necessary to supply each port
individually.)
