ABB Air Control Unit (ACU)

The ABB Air Control Unit (ACU) is a high-performing and costefficient air flow controller for paint applications that is easy to integrate into new and existing installations. This extremely accurate and reliable unit controls air flow, enabling paint atomizers an incredibly fast response time, at an even lower working pressure than existing solutions.

Lightweight and compact, the ACU can be installed directly on the paint robot arm of both IRB 5400 and IRB 5500. As compared to the PPRU which is mounted inside the pneumatic cabinet on the IRB 5500, situated outside the spray booth. 

The new ACU design gives you faster response time plus stable and uniform air flow.

Optimize your paint process with the ACU to get access to all the benefits and significant paint- and energy savings.

Benefits include

Paint savings: 

− Minimized overspray

− Improved paint quality result

Energy savings:

− Lower air pressure

Productivity improvement:

− Reduced stop time

− Increased throughput

Paint savings with IPS

With the new ACU‘s millisecond response time you can now take full advantage of BB’s IPS system, designed to save paint. High acceleration painting robots combined with fast process regulation provide optimum use of paint material. In short, IPS reduces your cost to make you more profitable.

Quick and easy replacement 

The ACU replaces MAC-kit PPRU units on S4P, S4P+, and IRC5P paint robots. The replacement may require some adjustments for older generations. The ACU is a plug-andplay solution with pre-calibrated settings, easily fine-tuned or customized, ensuring an extremely accurate and stable overall performance.
