The Chief Dust Extractor 63L offers a smaller, more economical version of Chief's original Dust Extractor 85L, with all the same features and benefits. The extractor has a detachable water tank that functions as a wet mix separator, as well as a clear tube gauge that indicates when the tank is full. It is compatible with any pneumatic sander that has a vacuum function and can service two sanders at once. The extractor is stainless steel and comes with a coalescing HEPA filter that captures 99.995 percent of ultrafine contaminants at .3 microns in size, according to the company.
