Multistage Ejector
CVZ Series

Equipped with a three-stage flow multi-nozzle system, delivering a maximum suction flow rate of 877 L/min (ANR).

Ideal for handling porous workpieces, heavy loads, and large-volume evacuation.

Three-stage nozzles provide both a high suction flow rate (up to 877 L/min (ANR), Note 1) and a high vacuum level (-88 kPa). By using the exhaust air from each nozzle as the supply pressure for the next nozzle, it achieves extremely high efficiency.
Note 1) For model CVZ-4-ZSR at a supply pressure of 0.55 MPa.

Vacuum Handling of Sheet Metal Parts

Multiple ejectors can be consolidated into a single CVZ unit, reducing the number of units required and simplifying maintenance.

Cardboard Box Suction

The ejector's suction flow rate exceeds the air permeability of the workpiece, enabling stable suction.

The number of nozzles (air consumption) can be selected according to the required suction flow rate.

By selecting the 0.3 MPa supply pressure specification, the compressor discharge pressure can be reduced, enabling energy savings and providing a greater pressure margin.

A large-capacity filter can be installed to separate foreign matter and debris.

Clear Case for Visual Clog Inspection.

Can be disassembled for cleaning, and the filter element can also be replaced.

Can be directly mounted to the suction port of the CVZ.

Equipped with a vacuum pressure monitoring port, allowing a pressure sensor to be mounted directly on the unit.

Note) It is not possible to install both a box-type pressure sensor and a large-capacity filter simultaneously, as they interfere with each other. If both are required, attach a fitting to the vacuum pressure monitoring port and use tubing or similar means to extend the connection before mounting the pressure sensor.
