Product Overview

The DEWALT 20V Powered Water Tank (Tool Only) is the convenient, portable way to provide a non-potable water supply to the jobsite. The 4 gallon (15 liter) tank provides water based dust suppression when cutting concrete or masonry with cutting or drilling equipment. The electric pump works with any DEWALT 20V MAX* battery (sold separately) and allows the user to work more efficiently because there is no need to manually pump the water tank.
