COAX^® is an advanced solution for creating vacuum with compressed air. Based on Piab’s multistage technology, COAX^® cartridges are smaller, more efficient and more reliable than conventional ejectors, that allows for the design of a flexible, modular and efficient vacuum system. The two-stage COAX^® cartridge MICRO is probably the world’s smallest multistage vacuum ejector. Its low weight makes it suitable to integrate close to the suction point in high speed pick-and-place applications of small objects. The two-stage COAX^® cartridge MINI has small mounting dimensions and the three-stage COAX^® cartridge MINI has high initial vacuum flow. The two-stage COAX^® cartridge MIDI has small mounting dimensions and the three-stage COAX^® cartridge MIDI has high initial vacuum flow. The MIDI cartridges are efficient generators of blow-air and are also suitable for fast evacuation of large volumes.
