When using 8" insulated flex duct between the blower and filter, is there a problem keeping the duct from blowing off from the back pressure? I don't really know what to expect for maximum back pressure when using 2 partially clogged Wynn filters (normal dust buildup). The force on an 8" ID duct should be about 2 lbs/WC". I suppose putting something like gaffer's tape on the pipe or fitting before putting the flex duct on with a hose clamp would hold it on better.
