I covered the openings in the front of my saw with magnetic vent covers. The DC still pulls in plenty of air through the back of the saw, but I get none out the front. I also use a zero clearance insert and yes there is some sawdust on the table, but the majority goes out the bottom of the cut. You can't close all the openings or you will not remove any sawdust. You have to leave an opening at least the same size as the exhaust port.

I have a table mounted router and if I forget to turn on the DC when running the router the air in the enclosure gets warm very quickly.
