Vacuum Pumps and Vacuum Generators
Energy Saver Vacuum Pumps With Pneumatic Pilot Valve
JEDS-P Series

The JEDS-P Series Energy Saver Vacuum Generator features programmable vacuum level and blow-off, adjustable flow volume, and vacuum loss prevention. Compressed air is used only when required to maintain the vacuum. Standard check valves are built in.

The JEDS-P system can be used in automation applications to replace conventional vacuum generating stations. This is a dependable and energy efficient system. The JECS-P is equipped with a pneumatic control for explosion-proof applications.
