Note 2) The unit selection function is not for use in Japan due to a
new measurement law. (October 1999)

Note 5)
With check valve
Note 4) The check valve has a function to prevent
the exhaust air from the silencer overflowing
to the vacuum port side when a manifold is
used, but it cannot prevent overflow of the
exhaust air completely. During usage,
please inspect thoroughly with actual
machine.
Note 5) When VA or VB is specified for (1), the check
valve is already built in.
