SurfPrep 3" x 4" Storm Air Sanders


SurfPrep’s 3” x 4” 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. 
You will need a minimum 80 gallon air compressor to run air sanders properly.

User Manual

*Product Update*

SurfPrep is updating their 3" X 4" tools, accessories, and abrasives with a new 6-hole pattern instead of the standard 4-hole. Throughout the next few months, all inventory will be replaced by the 6-hole pattern. Once replaced, 3” x 4” 4 hole items will no longer be available. Please keep in mind that a 4-hole abrasive will work great on a 6-hole backup pad and vis-versa.
