I have the kind of dust collector with a canvas bag, I believe a 3 HP motor (on 240v), and 2 4 inch inlets. i am sure it is manufactured in Taiwan or China. You know the one. The name plate fell off but I think it was branded "penn state industries".
Anyway, I have one of the 4 inch inlets blocked off and use a single hose from the other and just disconnect and reconnect to my various machines. For the most part this works fine, but I am wanting to get better dust collection on my table saw and router table.
Would it be advantageous to remove the two 4 inch inlets and replace them with a 6 inch inlet? Or should I look at other modifications like using a canister instead of the canvas bag? I know that canvas bags are less than ideal for a lot of reasons, but I am not sure if one of them is actually air flow volume.
