The JBC Tools FAE2-5A SMART Fume Extractor is the most efficient solution to avoid exposure to solder fumes and only operates when it detects it is needed. It works with the soldering equipment and starts up when the tool is used. By only turning on when needed it will help save power and extend the life of the equipment. It features a vacuum system integrated into the stand that detects when the tool is at rest and automatically absorbs the fumes. The JBC Tools FAE2-5A SMART Fume Extractor can be used simultaneously in two work areas and has 4 working modes (3 predefined levels of aspiration – Low, medium, and high, and a custom mode). The custom mode allows the user to set the airflow with the low (10%) and max rates (100%).
