Has 2-1/2 female vacuum adapter (actual mating surface diameter 2.25")

Sanding kit provides hosing and bucket to work with any standard wet/dry shop vacuum to eliminate 95% of the dust from drywall sanding.  

The Sand&Kleen system uses a 5-gallon Aqua-Air filter. It allows for 20' of reach from the Sand&Kleen sanding head to the filter. The sanding head has 36 suction ports and uses any standard abrassive screen.

Does require more effort because of suction and scratches drywall surface pretty easily.


Please clean after each use- drywall dust is not toxic.
