Piab piSAFE Vacuum Safety Ejector Review: Specs, Price and Applications
Piab piSAFE is a COAX-based vacuum ejector with integrated control functions and a vacuum safety non-return valve that holds vacuum in sealed applications during system or power failure. A sensing port connects a good-to-go switch.
Energy-saving features reduce air consumption by up to 98% per cycle. Several release options, centralized or decentralized use, multiple mounting interfaces and a modular design are available. It targets robots requiring high safety, ergonomic lifting devices and cranes meeting EN 13155 and ASME B30.20.
Quick Verdict
A cost-effective safety upgrade that replaces vacuum tanks or mechanical backups while saving almost all the air in sealed holds.

Design and Operating Principle
In sealed applications such as glass or sheet, a check valve traps vacuum in the cups if air or power fails, so the load is not dropped. That can replace more expensive mechanical locks or vacuum tanks.
With energy saving, the ejector switches off once vacuum is reached and only restarts if it drops, which is how air use can fall by up to 98% per cycle.
Light materials reduce EOAT weight, lowering wear on robot drives or allowing a smaller robot.
Integration and Selection
Use on sealed loads where hold-on-failure is required. Connect the good-to-go switch to interlock lifting.
Verify compliance of the complete lifting device with the relevant standard.
