MADE IN THE U.S.A.!!! I developed the FAN NOZZLE-HF1 attachment to throw out a wide narrow pattern of powder to help with covering a large area of sheet metal or expanded metal in a more efficient manner, much like a professional paint spray rig does. The FAN NOZZLE-HF1 has a 5/16th inch slot machined into a very dense hard plastic that will give a long service life and repeatability.
