COAX is a technical evolution for generating vacuum from compressed air. Based on Piab's multi-stage technology, COAX cartridges are smaller, more efficient and more reliable than traditional ejectors, facilitating the design of modular, flexible and energy-efficient vacuum systems. The COAX MICRO two-stage cartridge is without doubt the world's smallest multi-stage vacuum cartridge. Its ultra-small size means it can be integrated directly at the suction point for high-speed pick-and-place applications involving small objects. The COAX MINI two-stage cartridge is smaller in size than the COAX MINI three-stage cartridge, which has a higher initial suction rate. The COAX MIDI two-stage cartridge is shorter than the COAX MIDI three-stage cartridge, which has a higher initial suction rate. MIDI cartridges are capable of both blowing a lot of air and rapidly evacuating large volumes of air.
