Sure, but we're talking about shopvacs. Wood dust extractors are their own very different thing and usually come with a whole network of ducting around the shop. What's more, good wood and metal shop practice includes a real air purifier like from Grizzly or Jet (for cheap options) to cycle air through layers of filters. My metal shop has one, it cost $250. Wet/dry vacs are for cleaning up and maybe preventing a bit of spread at the source.
