Understand the confusion. This was my setup idea. Similar to yours. However in this configuration, my impeller is turning in a clockwise direction, pulling air out of the Dust Deputy. However, the Dust Deputy air flow is working in a counterclockwise direction. The air meeting the impeller right where you can see the silver joint tape is air colliding and messing up the airflow. From the second pic, I have drawn an arrow of the airflow out of the impeller - heading to the Wynn Filter. So my issue is counterclockwise air flow coming out of the Dust Collector meeting the clockwise pull of the impeller is dropping the vortex action of the Dust Deputy way down due to the turbulence. I can't reverse the impeller, but thinking more about increasing the distance between the Dust Deputy and the impeller and adding something like airvanes in the connection to make the airflow more neutral to both sides. Either that, or my space saving plan goes to poo and I have to stretch this out differently, but in my really tight shop, space is at a premium.
Thanks for any ideas!
