1. If a tube, stop valve or silencer is connected to the ex-
haust port of the VHS20/30, the effective sectional
area should be larger than the figure indicated in the
following table, to prevent malfunction caused by back
pressure. (This is not applicable to the VHS40/50.)
Caution on Mounting
Note) Use an air filter on the IN side for operating protection.
