View Printer-Friendly PDF Page


 The addition of a control valve for the air supply transforms the basic JB series vacuum generator into a compact vacuum system, with built-in vacuum control. The control valve is mounted directly to the vacuum generator body and all air passages are internal to the system.

Usage:
This vacuum generator is recommended for use where compact size and precise control are important. Pneumatic control is available for explosion proof operation as well as additional voltages.  Consult factory for assistance in choosing the proper vacuum generator for your application.
