I recently ran into an article on the internet about neutral vanes and air ramps and how they rob separation efficiency in order to increase air flow. Per the article allowing the circulating air to collide with the incoming air improves the collection efficiency and the neutral vane and air ramps have been installed in the home shop market DC’s to reduce pressure drop and keep HP and blower size smaller.

So the solution to clean filters is still frequent cleaning or maybe a commercial DC.

I clean my filters by reversing the flow threw my filters after each use. I keep my filter pressure below .5”H2O. I recently sanded 35 bf of maple down from 15/16 to 3/4 ” with a 24” drum sander. The filter pressure never changed.
