PAASCHE AIR ERASER COMPOUND 5lb
240 grit aluminum oxide abrasive. This is the standard size that comes with the AEC-K. We have added a 400 grit so we changed the part number from AEX-5 to AEX-5-240. This is the largest grit size that can be used with the AEC model. The AECR and LAC can go slightly larger.
