- Suitable for handling a wide range of workpiece shapes and sizes.

- Allows handling of uneven, heavy, porous and other workpieces by one hand.

- Easy operation with built-in Convum Vacuum Ejector to supply compressed air.

- Compressed Air generating Vacuum through the Convum Vacuum Generator (Ejector) is exhausted into the Balloon Hand, inflating it, and enabling the Balloon Hand to hold the workpiece firmly.

- Exhausted Air goes into the rubber film and inflates like a balloon.

- By using the exhausted Air of the Convum Vacuum Generator in this way, no Air is wasted.
