Product Overview
ABB ACU-01B (Part No. 3HNA024871-001/12) is an original high-precision Air Control Unit specially developed for ABB industrial painting robot systems, serving as the core pneumatic control component for automated spraying processes. Designed for automatic spraying production lines, it accurately controls the compressed air pressure, flow rate and air ratio during the spraying process, stably adjusts atomizing air and shaping air parameters, and ensures uniform paint atomization, consistent coating thickness and high surface finish quality.
Integrated with high-precision pneumatic regulating modules, signal acquisition and closed-loop control system, the ACU-01B supports automatic program linkage adjustment and dynamically matches robot spraying trajectories and process parameters. Adopting an industrial aluminum alloy body, it features dust resistance, pollution resistance, aging resistance and vibration resistance, adapting to long-term continuous spraying operation in workshops. It effectively solves process defects such as color difference, sagging and uneven coating thickness. The suffix /12 represents the factory batch version, with completely consistent core hardware specifications and full interchangeability with the standard model 3HNA024871-001.
