Chip or vacuum extractor for router table?

[Hsmith192]

Does anybody know if you should use a Chip or vacuum extractor for a router table??

The ports are comparatively tiny, so HPLV extractor is better as it will pull the air through them better.

Hi @Jake & all

I have a similar dilemma to the OP.

The port on the back of my router table fence is 63mm. Not that tiny.

I have two options. I could step down from the 100mm ports on either a HVLP double filtration chip extractor or a HPLV Numatic NVD750 shop vacuum.

Which do you think is preferable and why?

I've read the excellent guide to dust extraction by @siggy_7 but still not sure what the best option is in this scenario. Any advice appreciated!

Cheers!

63mm is tiny for a HVLP extractor. They barely like 100mm, and 63mm is well under half the area/volume. I'd use the Numatic.

Plus to get good extraction you need a wye to the machine port as well, which is invariably even smaller.

I run a Numatic NV750 on my router table. It works fine for most of what I use the router for.

Depends what router you have in your table. Are you talking the monsters going up to 1/2” shanked bits, using the large cutters for example regular door making. Or, something more middle sized say like a Bosch POF model, or a trim router in a desktop table. I have the NV750 on my beefier router table. Via a cyclone. My Makita trim router in a desktop table is connected to my wet’n’dry vac.

I have the Bosch GMF1600. Using 1/2” shanked bits including a slot cutter set and a large chamfer bit. From what you and others have said, it seems the NVD750 (with attached cyclone) is the better of the two options.
Cheers.

I should have mentioned in my post but didn't, I have the DeWalt DW625 on a half inch shank in my table and coupled to the NV750 through a cyclone.

I used both. I bought one of these and fitted it underneath the table, below a hole cut just beyond the insert plate; I refer to it as The Black Hole because it sucks in everything thrown forward. A 100mm hose runs to the larger extractor and a 63mm comes off the fitting to extract from the dust port on the fence. A small shop vac hose connects directly to the router.

This is the one I have been using, swapped my numeric for it, and it has a larger diameter pipe than the numeric I did get the turbo head from eSpares and what a difference that makes I just plug my power tool into the plug on the vac and as you switch it on the vac starts up, so there’s no messing about with two switches I think they are Swedish, I’ve got there power washer as well about £60 if it breaks at that price I’d just get another but I’ve had it 3 years and it’s still going

This is how I made mine. I cut the front off a soil pipe fitting (100mm) and attached it to the fence. There is also a repurposed Scheppach hold down roller. These are great, spring loaded in the vertical plane and by turning the rubber wheel pivot in they also push towards the fence.
Basically a hand powered 'power feed'.
The only 'fault' in my system is that you cannot separate the infeed and outfeed fences.
