■  Characteristics

●Selection of the most suitable module for your application is possible by the modularized each unit and rich combination of units.

●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.

●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).

※ⅰSuction flow of the vacuum port size with 5/32" O.D. and ø4mm may be different from the above values.

※ ⅱ Supply pressure is 72.5psi (0.5MPa) for H and L type and 50psi (0.35MPa) for E type.

※ ⅲ Air consumption values in ( ) represents that of E type.

※ ⅳ The values in the table are reference values only. Suction flow varies according to the vacuum system conditions; vacuum port dia. or tube length.

④ W → Combinations (18 types)

⑤ 1/4 → Vacuum port (tube dia.)

※5/32" (code: 5/32) and ø4mm (code: 04) is selectable for Nozzle Bore 0.5mm and 0.7mm only.

■ Manifold type (VKM)

00：Applicable to a manifold installation top-mounting unit alone, with the port to be installed on the side and to model code for manifold-base alone with different vacuum port size.

※ ⅰ5/32" (code: 5/32) and ø4mm (code: 04) is selectable for Nozzle Bore 0.5mm and 0.7mm only.

※ ⅱRefer to the Manifold Type reference picture to select the port position.

⑥ 1/4 → Air supply port (tube dia.)

■ Stand-alone type

※5/32" (code: 5/32) and ø4mm (code: 04) is selectable for Nozzle Bore 0.5mm and 0.7mm only.

■ Manifold type (VKM)

⑧ E → Solenoid valve type

⑨ B → Color

⑩ □ → Number of stations (Manifold type only)

※ Special-order for those with 11 or more stations.

⑪ □ → Vaccum switch (※ Selectable only when ④Combinations is one of E, F, L, M, R and W)

■ Piping Example

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 blowoff 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 generatesvacuum.
