Festo VADMI-140-N Venturi vacuum generator with 1.4mm Laval nozzle. Achieves 85% max vacuum. Features integrated NPN switch, ejector pulse, and IP65 rating.
The Festo VADMI-140-N (Part Number: 162531) is a high-performance, single-stage vacuum generator operating on the Venturi principle. This model features a 1.4 mm Laval nozzle capable of achieving a maximum vacuum of 85%. Engineered for industrial handling and automation tasks, it integrates a threshold value comparator vacuum switch with an NPN electrical output for real-time monitoring. An integrated ejector pulse valve facilitates the rapid and reliable detachment of workpieces, minimizing cycle times. It also incorporates a built-in 40 µm compressed air filter to protect the system and an integrated closed silencer to reduce exhaust noise. Rated for an operating pressure of 2 to 8 bar and powered by a 24V DC supply, its robust wrought aluminum alloy housing ensures durability. The compact 22 mm grid dimension unit offers an IP65 protection class, making it highly reliable in demanding automation environments.

Integration into robotic end-of-arm tooling (EOAT) for lifting and maneuvering non-porous objects like sealed boxes or plastic containers.
Ensures quick cycle times during pick-and-place operations. The integrated ejector pulse valve forcefully detaches the payload without delay, preventing latency during part release.
Used in automotive or metalworking facilities to feed sheet metal into stamping presses or transfer panels between machining stations.
Accurately monitors vacuum levels to prevent dropped parts. The integrated NPN vacuum switch continuously checks the threshold, immediately signaling the PLC if leakage causes the vacuum to drop below safe holding levels.
Utilizing the vacuum generator in clean or semi-clean environments to pick and place delicate electronic components or silicon wafers.
Prevents contamination and limits exhaust noise in precision assembly lines. The built-in 40 µm filter stops internal fouling, while the integrated closed silencer ensures the exhaust air does not exceed local noise constraints.
