What is an air economy circuit?
When a vacuum generator is being used without other additional functions, it requires energy for as long as “Vacuum on” is active. If a vacuum generator with vacuum monitoring via a sensor and an integrated non-return valve is being used, the vacuum only needs to be created (and thus energy consumed) if the vacuum falls below a predetermined level. As long as the vacuum in the system remains within the preset limit values, the vacuum generation is automatically deactivated to save energy. An energy economy circuit like this can be controlled via a PLC. However, the control system can also be fully integrated into a vacuum generator.
