Under-table router dust collection cabinet

I built my own years ago and quickly found out that I needed to create a way to regulate to air-flow.
It worked well enough until I got the Triton router. It would physically fit in the box, but the lift crack knob was very difficult to actuate. I removed to box and just used the built-in hose connection. Because of all of the cladding built into it, this does work pretty well, depending on the type of cut. Sometimes the fence connection seems to work better.
I do have the capability to Y them together, but don't do that very often.
 
Well, it's not the prettiest thing, but I managed to slap together a quick cabinet from some leftover 3/4" MDF, glued and screwed. I might add some magnets to hold the door in place but with the DC turned on, there's more than enough suction to hold it. I attached it to the worktop with several 3-1/2" cabinet screws.

My INCRA CleanSweep rings arrived this afternoon so I'm looking forward to seeing how well it all works.

I've used the original Dust Router Y hose, now marketed by Milescraft on my self made table for more than 20 years.  I have a PC 7518 mounted in a massive Bench Dog lift and an Incra Wonderfence.  The Dust Router hoses are connected to a 2" Fein hose and a Festool Y splitter.  There is minimal fall through under my table with this setup which enables me to store my bit box and CMT spiral and wing cutter sets below.  Router is totally unenclosed and has run at times when fabbing plastics and quarter sawn red oak for 8 hours at a time.

IMO this is the best system. It does initially take a little more fussing conceptually and mechanically but it is the most effective.

The big box under the router is nice and simple but it puts negative pressure right at the motor cooling fan attempting to reverse the cooling air flow the manufacturer designed.

Wouldn't this be a problem with all router boxes? Or is there something with my DIY box that I should've done differently?

Andrew Klein recently developed a dust extraction box that does not enclose or suffocate the router motor.

Your box is fine. You may need an adjustable opening on the side. Sometimes when router insert ring is small it restricts airflow too much.
I disagree with previous post about negative pressure affecting cooling. It's the same pressure (95+% of normal atmospheric) throughout the box and the motor is simply pooling it from one side to another. Obviously, you need DC running to ventilate the box.
Having said that, I was always suspicious of these boxes causing more dust to circulate through the motor. However, I've never heard from people who operated these for years to notice any ill effects of this setup.

Andrew's setup reduces the airflow at the bit too much IMHO, because now DC has to suck additional air that motor takes from the outside and pumps into the box. And that's a lot of air, much more than those adjustable vents you see on router enclosures.

Thanks, Svar.

I'll be using these rings which are meant to help with flow and collection. I'll look into adding one of those adjustable vents like what is on the side of the Rockler box.

Looking good. It's basically finding the right balance between all the openings and DC suction for optimal collection via trial and error.
 
4nthony your dust box looks great and will do the trick I think.

Those Incra rings with the extra slots etc will increase the extraction at the bit nicely I think.

I modified my router lift plate inserts by drilling extra holes to achieve the same thing.
