SurfPrep’s air (pneumatic) sanders require a large compressor that is typically found in production facilities in the commercial cabinet industry. To power a pneumatic sander, your compressor needs to have an air tank of at least a 90-gallon capacity and capable of producing a constant 3.4 CFM of air at 90 PSI. (A tank of this size will still empty in less than two minutes and cannot catch up to maintain the 3.4 CFM requirement.)
The electric sanders are more versatile as the only requirement is an electrical outlet. For that reason alone, they are the smart choice for using in client’s homes when doing cabinet refinishing and for DIYs at home or in your shop.
