The sprayer features multiple adjustable settings to suit your project needs, including an adjustable flow control, spray width, spray pattern and variable speed power settings displayed on the LED panel. The sprayer also includes two nozzles: the iSpray nozzle for spraying broad surfaces like shed siding and a Detail Finish nozzle for spraying a smooth, fine finish on projects like cabinets and furniture.
