VK Series Vacuum Generator

Share to:
18 different combinations of multi-functional vacuum generators which are also available as manifolds.
  1. Vacuum Generator can be used in various combinations with built-in check valve, vacuum switch, vacuum breadking valve, etc., or their units to suit your applications.
  2. The vacuum switch offers a selection between the high-performance electronic type and the low-cost, easy-to-use mechanical type.
  3. The vacuum breaking valve, which allows you to choose from the solenoid valve type and the air timer type, incorporates a special change-over valve, thus enabling quick breaking of vacuum or air blowing.
  4. Multiple vacuum generators can be formed into a manifold, and each of them can be set to a different capacity.

Product Description

  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).

Main Dimensions

■ Piping Example

VPC VK - Pneumatic Vacuum Ejector

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.
