The 1050 model offers power and durability with its 20 gauge steel tank for collection and strong 176 CFM airflow. The HEPA filtration system filters out nearly 100% of the dust produced when milling drywall keeping the work area dust-free. Like all PanelMax vacuums the 1050 uses patented technology to clean the filter while you work so you never have to stop work to unclog a filter. For use with PANELMax ST48 and FT30.
