The particle suction extraction developed and patented by CleanControlling represents a unique extension of the testing spectrum of technical cleanliness. With the further development of the suction extraction system C|PS², which was first presented in 2018, the complete system C|PS³apex, equipped with a digital control system, represents a further milestone in technical cleanliness today. The fully equipped complete system with digital user guidance ensures reliable performance of repeated tests. The compact system C|PS² enables the mobile use of the suction extraction, e.g. on site in the production environment.
