BACU | Breathing Air Charging Unit
Ensure your breathing air cylinders are filled safely and in full compliance with EN 12021. Zeevenhooven Air's breathing air filling units are designed to deliver high-quality breathing air for industrial and emergency response applications, guaranteeing a reliable and certified air supply every time.
Available as both trailer-mounted and compact indoor models, our filling units are suitable for filling 200 and 300 bar breathing air cylinders. Built for reliability and ease of use, they provide an efficient solution for companies that depend on a continuous supply of certified breathing air.
Intelligent Buffer System
Our breathing air filling units are equipped with an integrated buffer system that significantly improves operational efficiency and ease of use. The buffer stores compressed breathing air, allowing cylinders to be filled more quickly and with fewer interruptions. This reduces compressor run time, minimizes waiting periods, and enables multiple cylinders to be filled in succession, making the system ideal for demanding industrial environments where productivity and continuity are essential.
