The document summarizes technical specifications for AIRTEC Central ejectors. The ejectors use the Venturi principle to generate vacuum up to 80% when compressed air flows through the nozzle. Models include automatic air-saving functions and blow off capabilities. Vacuum levels can be preset or reprogrammed depending on the model. Accessories include silencers that are included to reduce noise.

Series Functions Air consumption Model code PE = Vacuum, air-saving automatic function 150 = 150 Nl/min see accessories and blow off, without vacuum switch (0.152 Cv) page 75 PEV = Vacuum, air-saving automatic function and 300 = 300 Nl/min blow off with pre-set vacuum switch for parts control (0.305 Cv) PEVT = Vacuum, air-saving automatic function and blow off 500 = 500 Nl/min with re-programmable vacuum switch for parts control (0.508 Cv) Design and function Central ejector based on the Venturi principle. Includes integrated solenoid valves, air supply connection, and vacuum connection. When the solenoid Y1 is activated, compressed air flows through the Venturi nozzle generating vacuum. An integrated check valve 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 when sole- noid Y2 is activated. The protective filters are cleared of debris and the double solenoid valve is closed as well. (The pressure supply port and the suction connections are fitted with removable protective filters which protect the ejectors from debris.) A silencer with self-cleaning granular filling (with an air consumption of 150 and 300 Nl/min) or a surface mounted silencer (with an air consumption of 500 Nl/min) is included in the scope of delivery.
