2 Key features Product overview Vacuum generator All Festo vacuum generators have a single stage design and operate according to the venturi principle. The product families described below have been designed for a wide range of applications. The different performance classes of the individual product families make it possible to select vacuum generators tailored to suit specific requirements. Standard and inline ejectors VN Ī 6 / 9 Nominal size 0.45 Ī 3 mm Max. vacuum 93% Temperature range 0 Ī +60 C A range of extremely effective generators suitable for use directly in the workplace Available as straight or T shaped housing Low space requirement Low cost No wearing parts Extremely fast evacuation time Vacuum switch (optional) VAD Ī/VAK Ī 6 / 35 Nominal size 0.5 Ī 1.5 mm Max. vacuum 80% Temperature range 20 Ī+80 C Range of vacuum generators with sturdy aluminium casing VAK Ī: Built in reservoir VAD Ī: Connection for additional external reservoir Maintenance free VAK Ī: Reliable setting down of workpieces 6 / 2 Products 2004/2005 Subject to change 2005/07

Laval nozzles in six nominal sizes: 0.45 mm 0.7 mm 0.95 mm 1.4 mm 2.0 mm 3.0 mm for high suction rates resulting in very short evacuation times Low space requirement Compact and sturdy design Wear resistant and maintenance free Modular system: Large selection of different types Can be used directly in the workplace, making them very effective Plastic housing Versatile connection options: Push in connector QS Screw in thread Push in sleeve Screw in silencer Easy mounting thanks to the double sided latching function of the mounting plate With or without integrated vacuum switch to monitor the vacuum with PNP output Two housing types Standard T type Connection options: QS push in connectors Female thread Male thread Silencers Mounting options: Direct mounting with screws Indirect mounting by latching onto a mounting plate. This plate is suitable for H rails 35x7.5 to DIN EN In line version Connection options: QS push in connectors Push in sleeve Mounting options: Extremely compact housing with supply and vacuum port arranged in a line and with unducted exhaust air. As a result, this housing type can be installed directly into the tubing line. Two operating principles Standard T type housing Design: Supply port at 90 to vacuum port. The drawn in flow is diverted 90 from V to R. Inline T type housing with exhaust port Straight housing without exhaust port for space saving assembly in a tubing line or directly in the suction cup holder Design: Supply and vacuum ports arranged in line. 6 / 4 Products 2004/2005 Subject to change 2005/07

5 VN Features Two variants High vacuum up to 93% High suction volume up to 339 l/min which results in very short evacuation times Vacuum p u as a function of operating pressure p 1 Suction rate q ns as a function of operating pressure p 1 pu [bar] qns [l/min] System comparison High vacuum high suction volume The first type of generator has been optimised for the generation of high vacuum at comparatively lower suction flow rates. The second type of generator, on the other hand, can achieve very short evacuation times because of the high suction flow rate at relatively low vacuum. pu [%] t [s] High vacuum High suction volume 2005/07 Subject to change Products 2004/ / 5

34 VAD/VAK Key features and type codes At a glance Vacuum generation via ejector principle Mounting holes in metal housing Connecting thread for the suction cup Compressed air flowing from 1 to 3 generates a vacuum at port 2 in accordance with the ejector principle. The low noise levels which occur during exhaust can be further reduced with a silencer at port 3. Workpieces can be picked up in any position. When the compressed air is turned off, the suction process ends and the vacuum dissipates. During the suction process, the vacuum generator VAK fills a reservoir of approx. 32 cm 3 with compressed air, which creates an ejector pulse when the input pressure is switched off and reliably releases the workpiece from the suction cup. Max. switching frequency approx. 10 Hz at 6 bar and with approx. 1 m suction line. Vacuum generator VAD Ī without ejector pulse Workpieces can be picked up in any position. Sturdy and resistant to environmental factors Easy to install No moving parts, maintenance free Connecting threads and mounting holes available Exhaust air (3) Vacuum generator Vacuum suction cup Vacuum (2) Compressed air (1) Vacuum generator VAK Ī with ejector pulse Quick and reliable setting down of parts via an ejector pulse from a pre filled reservoir Robust vacuum generator for a broad field of applications Optional silencer Connection for additional external reservoir Integrated reservoir for quick release of parts Vacuum generation based upon the "venturi principle" Aluminium housing Wide selection of suction cups and complete suction grippers VAD M5 Type VAD VAK Vacuum generator Vacuum generator Connection sizes M5 Thread M5 x Thread Gx ¼ Thread G¼ y Thread Gy H Note Possible combinations can be found in the ordering data. 6 / 34 Products 2004/2005 Subject to change 2005/07
