This is a Paint Zoom, a popular type of high-volume, low-pressure (HVLP) paint sprayer. The kit includes a blue main unit housing the motor and a compressor, a black spray gun for applying paint, and a flexible hose connecting the two. It also comes with accessories like a viscosity cup, used to ensure the paint is thinned to the correct consistency. This sprayer is designed to provide a quick, even, and smooth finish for home and DIY painting projects, eliminating the need for traditional brushes and rollers.
