Vacuum Generators In-Line Type of Venturi Vacuum Generator VU,VUM,VY Vacuum Pad Direct Mounting In-Line Type Small-seized In-Line Type Blow-Off Mechanism Equipped Type Compressed air (P) Vacuum Generator VU （Pipe Type Union Straight） Air powered venturi vacuum can be used in combination with a vacuum pad to handle materials. Vacuum Tube Vacuum Pad Vacuum (V) Work-piece in line vacuum generator coming with a plastic body is very lightweight and compact. VUM Type ( Super small In-line type) ● Super small and lightweight vacuum generator Outer diameter : 0.33 inches (ø8.5mm), Weight : Max. 0.3 oz. (7.7g) ● Nozzle VY Type ( With Blow-Off Mechanism) ● Ejector and Blow-Off Mechanism are integrated. VY Type provides a high cost performance, compared to a normal solenoid valve equipped type. ● Small and lightweight body makes it possible to place on the terminal part of the vacuum piping. High speed cycle of suction and Blow-Off Mechanism is achiev

Blow-Off Mechanism Equipped (VY) Type ■ Example 1 ■ Example 2. Usage with Twin 3-way valve (SVA21). Check valve Connect P Port and PD Port with Check Valve (Purchase separately). The residual pressure between Check Valve and PD Port turns into a blowoff air. The flow rate of the blow-off air is adjusted by a release needle. Blow-off time can be controlled by the tube length between Check Valve and PD Port. Work-piece can be released instantly by adjusting a blow-off pressure and a flow rate. But it is necessary to pay attention not to blow away the work-piece. The above figure shows an example...
