Vacuum Pumps and Vacuum Generators
Air Powered Vacuum Pumps with Supply and Blow-off Control Valves
JBD Series


Note: JBD shown with Electronic Vacuum Switch.

These pumps are also available with internal safety check valves.

The JBD Series Vacuum Generators allow you to create a vacuum generating system with separate controls for the air supply and the blow-off. Two valves are mounted to the generator body, and all air passages are internal, creating a compact, leak-proof system. The blow-off feature can be regulated in time through control programming, or in volume, with a built-in adjustable needle valve.

We recommend using these generators with single- or multiple-cup vacuum systems that require an object to be pre-cleaned before handling and/or the quick release of a load. The JBD Series can decrease the overall operating cycle time by allowing you to break the vacuum seal quickly.

Specify pneumatic control for explosion-proof operation.
