The latest dust extractor from Festool, the CT SYS, is extremely compact and portable. It weighs just 15 pounds and fits into a systainer 2 (with a hose garage in a systainer 1). Even in a small package: its HEPA certified, has on-board storage for a crevice tool and upholstery tool and has manual and tool-triggered operation.
The CT SYS is Festool's most compact, portable dust extractor. The Dust Extractor fits inside a Systainer 2 and comes with a hose garage the size of a Systainer 1. It's small enough to carry around with the included shoulder strap.
