Piab COAX-in-piGRIP Decentralized Vacuum Gripper Review: Specs, Price and Applications
COAX-in-piGRIP is a decentralized vacuum gripper from Piab that generates vacuum independently at each suction cup. It is designed for very demanding applications with leakage or high speed.
Typical uses include handling smaller parts, bag handling and bag opening, and palletizing smaller boxes in food, consumer, cosmetic and pharmaceutical industries. It accepts the wide piGRIP cup range, mounts on extruded profiles and has auxiliary ports for vacuum switches and blow-off check valves.
Quick Verdict
An elegant building block for multi-cup grippers. Vacuum at the point of use gives fast response and isolates leaks to individual cups.

Design and Operating Principle
In a centralized system, hoses connect many cups to one generator, so every hose adds volume to evacuate and a single leaking cup can drag down the vacuum of all others. COAX-in-piGRIP places the ejector at the cup, so response is immediate and each cup works independently.
Because no vacuum flow is lost in hoses, energy efficiency is high. Flush-mounted cups keep build height low, and multiple mounting directions save space on the lifting device.
Auxiliary vacuum ports accept switches for grip confirmation and check valves for controlled blow-off.
Integration and Selection
Build multi-cup grippers on extruded profiles with the mount kits, choosing cups from piGRIP to suit the product.
Add vacuum switches to confirm grip at critical cups.
