Vacuum Generator Series
■ Characteristics
●
Easy maintenance by a lock-on manual button.
● 2 vacuum sensor selections: LED display Type and
Mechanical Type which is simple and user-friendly.
● An LED display is used for LED digital pressure sensor to
enhance visibility.
● Two types of vacuum switch : 2 switch output, 1 switch
output with 1 analog output are available depending on the
desired application.
●
4 Standard nozzle bores are 05(ø0.5mm), 07(ø0.7mm),
10(ø10mm) and 12(ø1.2mm).
● Blow-Off Mechanism can be selectable from solenoid valve
type and air timer (air chamber) type. The built-in switching
valve realizes fine tuning of quick blow-off air and fine
adjustment of air rate.

①Filter
Dusts sucked up from a vacuum pad are filtered and blocked from
entering inside the vacuum generator.
②Blow-off air rate adjustment needle
Turning the release needle to right (clockwise direction) reduces blow-
off air and turning it to left (counterclockwise) increases blow-off air.
③Vacuum Filter
Dusts and water drops exhausted from the vacuum generator are filtered.
④Filter / Regulator
Select a filter and a regulator which ensure an adequate flow pressure
and rate of VK.
⑤Vacuum Sensor with LED display
Easy adjustment of vacuum level by the LED display. 2 types of output
are available; ①2 switch output and ②1 switch output with analog
output.
⑥Blow-off Solenoid Valve (R)
The solenoid valve functions to release a work-piece from a vacuum
pad.
(Blow-off air is generated during the electric power supply)
⑦Suction Solenoid Valve (S)
The solenoid valve generates vacuum.
