Abstract
A tool allowing both the inflation and deflation of air-filled bags such as dunnage bags is disclosed. The tool comprises rotatable controls to easily and safely manipulate both the flow of air into the device and the mode of operation between inflation and deflation. A venturi tube is used to draw air rapidly from a bag when the tool is deployed in deflation mode, while a radial vent system dissipates the force of the air exiting the device during deflation.
