This new Makita 2.1 gallon vacuum meets OSHA Table 1 requirements based on its 99.97% filter efficiency, filter-cleaning mechanism and CFM rating.
It can be used for small drilling and chipping applications. the best part is it weighs 21.8 pounds. [including 2 batteries]
For us the compact, lightweight ability to get a cordless dust extractor operation to the jobsite was appreciated and makes following Table 1 easier.
