Function
AIRTEC Classic ejectors operate using the Venturi principle. Compressed air, ideally free from dirt and oil, flows through a Venturi nozzle, increasing velocity to supersonic levels. This creates a vacuum by mixing with atmospheric air in the vacuum line. Protective filters prevent dirt from entering the system, ensuring efficient vacuum generation and reducing malfunctions. A granular silencer minimizes exhaust noise and allows fine dirt to pass through. A blow-off valve can quickly dispel the vacuum, aiding in the release of workpieces and cleaning of filters.

Applications
The ejectors are suitable for handling and mounting applications, transport and conveyor systems, metal and wood industries, the automobile industry, pharmaceutical and food industries, packaging, manipulators, and robotics.

Design
HV Classic ejectors offer high vacuum performance with low air consumption. HF Classic ejectors feature an anodized aluminum body with a compact, robust design, providing higher vacuum performance than HV models with similar air consumption. Both types include removable protective filters and a silencer.
