Nil
Without option

B
With one bracket for mounting a
single unit
(Mounting screw is attached.)
Use when a single unit is mounted to the floor in an upright
position is requested.
(When ordering only bracket, refer to
C
Vacuum pump system PE port female
thread specification(M3)
Note 18)
Use for pilot pressure exhaust piping.
(Standard vacuum pump system is released to the atmosphere.)
If (3) combination of supply valve and release valve is R, select
the option with the relief pressure supply (PD) port .
Single unit / Manifold: Option (D)
Manifold: Option (P)
D
With individual release pressure
supply (PD) port(M3)
Note 19)
Use when supply pressure for vacuum release is individually
requested.
E
Vacuum release flow adjusting
needle.
Driver type long lock nut type
For manifold, vacuum pump system or exhaust port type,
tightening work of the needle is improved by lengthened lock nut
which tighten the needle.
J
Vacuum break flow adjusting needle
Round lock nut type
Thicker than standard hexagon type. More suitable for hand
tightening.
Round lock nut improves operability when manifold, vacuum
pump system, or exhaust port type is used.
K
Vacuum break flow adjusting needle
Screwdriver operation type
Slotted type improves fine adjustment performance when
manifold, vacuum pump system, or exhaust port type is used.
L
Manifold individual supply
specification
Note 20, 21, 22)
Adjust the supply pressure individually for manifold in order to
adjust the vacuum pressure reached by each ejector.
P
Manifold common release pressure
supply specification
When selecting “D” (with common release pressure supply (PD)
port) for manifold option, supplying a pressure which is different
from for common PV to common PD is requested.
W
With exhaust interference prevention
valve
Note 23, 24, 25)
When ejectors are operated individually, exhausted air may flow
backward from the V port of ejectors that are turned off. Exhaust
interference prevention valve prevents backflow.
Note 17) When more than one option is selected, list the option symbols in an alphabetical order. Example)

Note 18)
U
se One-touch fitting (M-3AU-4) or barb fitting for piping. (O.D.: within ø5.8)
Note 19) Use One-touch fitting (M-3AU-4) or barb fitting for piping. (O.D.: within ø6.2)
Note 20) Select when a PV pressure of 0.3 MPa or lower is required.
Note 21)
Select body for manifold. Select “L” for (5) Options for manifold model. When the common supply and individual supply are
mixed, please contact SMC.
Note 22) When
“F” or “H” is selected for (1) System/Body type and “L” is selected for (8) Options, the vacuum break flow-adjusting
needle option “K” can be additionally selected for increased workability.
Note 23) To prevent backflow of the manifold common exhaust, not for holding vacuum. This option does not completely stop the
backflow of the exhaust air. Select port exhaust type depending on purpose.
Note 24
) When “J” is selected for (3) Combination of Supply Valve and Release Valve and “W” is selected for (8) Options, install a
release valve or vacuum breaker.
Note 25
) When “K, Q, R, S” is selected for (5) Pressure Sensor/Pressure Switch for Vacuum Specifications, models with exhaust
interference prevention valve is provided. So, it is not necessary to select “W”.
