Has anyone tried adding a similar baffle to something like the Grizzly G0548Z? I am envisioning something that would go in the central section where the air comes in and maybe have a restricting ring on the top to induce the correct airflow.
I am wondering if it makes sense to have a slope on the upper ring to keep dust from accumulating on top when the filter is agitated after it is shut off?
I found this http://www.jpthien.com/smf/index.php?topic=145.0 (http://www.jpthien.com/smf/index.php?topic=145.0) that was basically the same design. I am going to try it.
