I have a 2 hp 1200 cfm DC and it couldn't remove all the sawdust either when I first hooked it up. I did a bunch of static pressure testing and found the bag filters and cyclone were robbing a significant amount of flow. That prompted me to reconfigure the whole thing, including eliminating the bag filters and blowing the air outside. After that, I had enough CFM at the bandsaw to handle the sawdust w/o a problem.
