Replaceable filters are built-in on the vacuum
and release sides.
L
Equipped with a pressure detection port
which allows for the connection of a
pressure switch, etc.
L
Can be
combined
with 4-port solenoid
valves, as well as SJ1000, 2000, and 3000
series valves (Special order)
(Please contact SMC for details.)
