The Coanda principle
The Coanda Principle
Operating principle
- Pneumatic operation with integrated vacuum generation
- With the Coanda principle, compressed air is guided through an annular gap which accelerates it
- The increase in the flow speed results in the “Coanda effect” in which the escaping air follows a convex surface
- The air flowing along the surface produces suction (“entrainment”) in the ambient air
Advantages
- High suction rate and low air consumption (the required operating pressure is 1 to 5 bar) due to the Coanda effect
- Large contact surface with narrowly positioned vacuum openings prevent the workpiece from being sucked in or damaged
