Design and function

Central ejector based on the Venturi principle. Includes two pressure supply ports and a vacuum connection.When connection 1.1 is supplied with pressure, the Venturi nozzle generates vacuum. An integrated check valve manufacturer at connection 2 maintains vacuum in systems with slight leakage even when the ejector is switched off. The integrated (automatic) air saving feature turns off the air supply to the ejector when the pre-set upper vacuum level is reached. If the vacuum level drops 150 mbar below this level, the air supply is turned on to the ejector until the pre-set vacuum level is reached again. This fulfills the “EMERGENCY ON FUNCTION”. To release the components that have been picked up, a momentary blow off ejects the components (a signal interrupter integrated into connection 1.2 stops the blow off function after 0.3 seconds). An external 5/2way double industrial solenoid valve is recommended to control the ejector by alternately activating connection 1.1 (start) and 1.2 (release). Change “release” to blow off as seen on page 66. The pressure supply port and vacuum connections are fitted with removable protective filters, which serve to protect the ejector from debris. A industrial silencer with self-cleaning granular filling (with an air consumption of 150 and 300 Nl/min) or a surface mount- ed silencer (with an air consumption of 500 Nl/min) is included in the scope of delivery. 62
