Bartell Global HD2 HEPA Dust Extractor features two-stage filtering with jet-pulse filter cleaning. Dual motors create 240 cfm of airflow @ 100" of water lift. Dual motor switches allow variable flow rates and lower start-up amperages. Filter cleaning is made easier due to inlet valve that allows pulsing to be performed without removing suction hose. Continuous Longo-pac bagging system allows easy emptying and zero exposure to collected dust. End users of the discontinued Husqvarna S26 will find the HD2 to be a great equivalent option.
