SurfPrep’s 3”x4” Storm Air Sanders have a low profile, compact footprint designed for use on flat surfaces, recessed corners, inside drawer boxes, & profiled moldings, etc. The durable, lightweight nylon composite bodied sanders withstand rugged industrial applications and are excellent for both prep & finish sanding. Both the Air and Electric Ray can be converted into a more “aggressive leveling sander” with the simple addition of a pad saver with SurfPrep Film cut sheets. All OEM parts are available.
