Topic tags/keywords: dust collection router table router

Hello, I’m trying to get equal quality dust collection under the router table vs at the fence. Here is my setup (all new): a Bench Dog Promax router table, a Bench Dog Pro Fence, a Triton TRA001 router, and an old Craftsman “shop-vac”.

I come out of the shop-vac to a Y-adaptor with 2.25 inch line to fence and 1.5 inch hose to Triton router dust port. The problem: apparently the large line going to the fence is “starving” the smaller line. The “path of least resistance” is to the fence. When bit is partially buried in the fence DC is great; lots of suction. Pull the fence away from the bit to mill a dado and there’s dust going EVERYWHERE. Very little is being pulled down. For reference this little test was with a 1/2” straight bit set at 1/4” high.

My solution for now is to just use fence collection when the bit is buried and connect the router direct to the shop-vac for operations well beyond the fence. With the router connected directly it works great; the shop vac is doing its thing and the Triton does a very good job of pulling the dust down.

Maybe my best answer as to build a box around the router with a 2.25 collection port, directional baffles and some ports in the front to assist with circulation. I was hoping to not have to go this far quite yet but maybe I will need to.

Does anyone have any suggestions short of the box? Your input would be very much appreciated.

There is the Dustrouter from keen-products. ( )
I do not have one so I cannot comment on it, however the reviews are positives. search on LJ
I am contemplating to get one however getting it shipped in Canada is prohibitive.
Let us know what solution is working for you in the end.
Good luck

I have the Keen DustRouter and it works very well. It’s actually a silicone shroud that surrounds the bit and creates massive air flow around the bit. So everything is pulled down and into the dust port.

The problem with the box method is, unless you have a huge dust collector, you don’t really get much air flow around the bit. So, the only dust that is captured is what just happens to fall below the table. And as you are aware, what is not caught by the fence port just flies all over the shop. Very little goes below the table. Because the DustRouter is right under the bit, it actually pulls everything in.

I highly recommend it. It’s cheap and installs in about 10 minutes.

Have your say...
