Note 5)
With check
valve
Note 4) The check valve has
the function of preventing the
exhaust air from the exhaust
unit from overflowing to the v
acuum port side when a mani
fold is used. However, depen
ding on usage conditions, it d
oes not completely suppress
air overflow.
Please thoroughly inspect the
actual machine before use.
Also, in order to completely p
revent the overflow of exhaust
air, leave plenty of space
between the check valve unit
and adjacent ejector to avoid
interference from the ejector's
exhaust unit.
Note 5) The check valve option
cannot be selected when “1U” is
selected for (2) and “J1” or “J2”
is selected for (3).
Warning
- The check valve cannot be
used for vacuum retention.
- Use a release valve.
Without a release valve, the
workpiece may not be released.

Note 1) The suction filter used in this product is a low-cost
filter. When used in a dusty or dirty environment, the
Filter
will quickly clog. If this is the case, consider using th
e ZFC series or other air suction filter along with it.
