Piab COAX Di16-2 Dust-Proof Cartridge Review: Specs, Price and Applications
The Piab COAX Di16-2 is a MINI-size, two-stage vacuum ejector cartridge without flap valves, designed so that dust and dirt pass freely through the nozzles. It reaches vacuum levels down to 21 inHg at a feed pressure of 87 psi.
It is designed for Piab's VGS3010 vacuum gripper system, which combines a suction cup and multi-stage air-driven pump in one unit, and targets dusty environments such as packaging with corrugated dust, where filters would clog.
Quick Verdict
A pragmatic fix for vacuum grippers that clog on cardboard dust. Removing flap valves lets debris pass through instead of stopping the line.

Design and Operating Principle
Multi-stage ejectors usually include flap valves between stages, which open and close as vacuum builds. In dusty environments, particles lodge in these valves and degrade performance. The Di16-2 eliminates them, so dust flows straight through.
COAX technology integrates multi-stage pump internals into a compact cartridge, making the ejector small, efficient and quiet. The cartridge format allows easy replacement within modular systems.
Combining humidity and dust can create sticky deposits; the free-flow nozzle design reduces the risk of clogging in such conditions.
Integration and Selection
Fit the Di16-2 in VGS3010 grippers used on corrugated cartons and other dusty products. Supply 87 psi feed pressure for rated vacuum.
Remove or avoid fine filters that would clog, relying instead on the cartridge's dust tolerance.
