Precautions
1. Insertion of the tube
(1)
Cut the tube perpendicularly, being careful not to damage the external surface. Use SMC’s tube cutter
TK-1, 2 or 3 for cutting. Do not cut the tube with pliers, nippers, scissors, etc. If the tube is cut by any tools
other than a tube cutter, the cut surface of the tube will be slanted or flat, making it difficult to be connected
securely, causing the tube to come off or air leakage after the tube is connected. Also, allow a sufficient
margin of tube length.
(2) Hold the tube and push it in slowly, inserting it securely all the way into the fitting.
(3) After inserting the tubing, pull on it gently to confirm that it will not come out. If it is not installed securely all
the way into the fitting, problems such as leakage or disconnection of the tube can occur.

Description
Ejector System
Vacuum Pump System
PV
Air pressure supply port
Compressed air supply for operating ejector
-
(Operating pressure range)
0.3 to 0.6 MPa
Note 1)
-
Vacuum pressure supply port
-
Vacuum source (vacuum pump)
(Operating pressure range)
-
0 to -100 kPa
PS
Pilot pressure supply port
-
Compressed air supply for pilot valve
(Operating pressure range)
-
0.3 to 0.6 MPa
PD
Individual release pressure supply port
Release pressure, Compressed air supply for individual setting (Option)
(Operating pressure range)
0 to 0.6 MPa
(PD ≤ PV)
0 to 0.6 MPa
(PD ≤ PS)
V
Vacuum port
For connecting adsorption equipment including pad
EXH
Exhaust port
Exhaust when ejector operates
Note 2)
-
PE
Pilot pressure exhaust port
Exhaust when valve operates
Note 3)
Note 1) For models without valve, pressure can be 0.3 MPa or less.
Note 2) For ejectors with silencer, air exhausts from A (slit on both sides). For port exhaust type, air exhausts from B.
Note 3) Pilot pressure for ejectors is exhausted from the ejector and the common exhaust. Vacuum pump system exhausts air from
PE port on the spacer. (Female thread type (M3) is available by option “C” for PE port of the pump system.)
