SurfPrep’s 3 2/3” x 7” Storm Air Sanders have a low profile, large footprint designed for use on flat surfaces, recessed corners, large areas & 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 Surge 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. You will need a VERY LARGE air compressor to run this sander. See video below before purchasing an air sander.
