Using the Miller FILTAIR Purifier is straightforward. First, make sure it's properly connected to a 460V, 3 - phase, 60Hz power source. Once powered on, the system will start capturing weld fumes and circulating filtered air. For safety, always keep an eye on the temperature sensor. If it indicates high temperatures, the water sprinkler may activate to reduce the risk of thermal hazards. Regarding maintenance, the self - cleaning pulsed air system helps extend the life of the FilTek XL Filters (MERV 15). When the filters need changing, you can easily access them externally without any tools. Empty the particle disposal bin regularly to keep the system running efficiently. And when using the integrated control panel, the simple and intuitive display makes it easy to operate and monitor the purifier.
