Donaldson BOFA’s innovative AM 400 filtration technology is now expanding across the U.S. to support a broader range of voltage requirements, making it even more accessible to advanced metal additive manufacturing operations. Notably, the AM 400 features a large filter design, enhancing filter life, reducing maintenance frequency, and improving operational efficiency.
The 230 V version of the portable fume extraction system released earlier this year in Europe, is now available, joining the previously released 110 V model. The AM 400 features patented technology to enable filters that capture particulate in inert atmosphere additive manufacturing printers to be exchanged securely on site. This is particularly valuable for metal additive manufacturing processes, such as aluminum and titanium printing, where pyrophoric reactions can occur.
The filtration technology enables additive manufacturers to exchange filters without risking oxygen entering the inert chamber environment, which could lead to a thermal event.
With Donaldson BOFA’s AM 400, filters are contained within a separate housing with a robust seal, enabling exchange to be completed quickly and safely without isolating the additive manufacturing equipment.
The AM 400 is engineered not only to improve safety during filter exchange in metal additive manufacturing but also to deliver measurable productivity gains by minimizing production downtime. This is especially valuable for manufacturers producing high-value metal components using additive manufacturing technologies. The system is hermetically sealed to maintain an inert gas environment, preventing oxygen ingress and ensuring process stability. With automatic flow control, users can pre-set airflow rates tailored to their application, reducing noise levels and helping to protect higher-value HEPA filters from excessive wear. As filters approach saturation, the system issues a timely alert, enabling proactive replacement and keeping operations running smoothly.
The 230 V model operates within an airflow/pressure range of 88 cfm min – 188 cfm max, while the onboard Intelligent Operating System (iQ) provides real-time data on extraction system performance, including individual filter status monitoring.
