The Freeman PHFBG High Flow Blow Gun with Venturi Nozzle provides more air flow than standard air guns and is perfect for cleaning out hoses, pipes, clogged lines, and gutters, and for moving large amounts of debris. This rugged air powered tool is built to last with durable and lightweight aluminum construction, and a comfortable pistol grip reduces fatigue while increasing control. The high performance variable flow trigger precisely controls air flow from the Venturi nozzle attachment, designed to fit into tight spaces. The High Flow Blow Gun with Venturi Nozzle connects to air hoses with 1/4" NPT threads, and makes fast and easy work of surface preparation or heavy duty clean-up projects around the garage, workshop, home, and jobsite.
