Topic tags/keywords: shop vac dust collector

I have a fairly long Shop Vac hose that would be handy to use with my Delta AP400 (1 HP) dust collector for cleaning cracks and crannies in the nether regions of my shop. Good idea? Bad idea? The vacuum burned up years ago or I would just use that.

The only consideration I’ve heard of is keep in mind a dust collector and a vacuum are different. Suck up a 1/2” nut with a dust collector and it goes through the fins unless you’ve got a separator inline. Using the hose to suck up dust should be fine.

You may well be disappointed with what happens. A DC isn’t made to overcome a lot of resistance, like a small hose. I think it may not move enough air to clean anything, but it won’t hurt anything to try. If anything the DC motor would just be coasting along waiting for more air to show up.

I will be adding a separator. The differences between how a DC and shop vac work are a mystery to me but I know there are differences.

Shop vac shave low airflow but high suction, so they work great with small hoses.

Dust collectors have high airflow but low suction, so they work best with large hoses.

Sticking a long 2.5 inch hose on a dust collector is going to disappoint you. Just use your shop vac for cleanup.

Rick, I use to have my vac hose connected to the dust collector, going to a miter station. It worked but in my estimate I lost 60- 75% of the suction before it hit the miter saw. It was still better than not having anything. I would disconnect it from the miter saw and clean up all around the saw, just what you have in mind. It just doesn’t have the same power. You loose a lot.

Rick, I stick a 2 1/2” shop vacc hose on my 1 HP Grizzly DC all the time to clean around the shop. It works just fine but won’t pick up some heavier items like bolts that the shop vac would (not necessarily a bad thing). I do have a chip separator to keep nails and metal out of the DC impeller.

Rick, take 2 swizzle stick like you stir coffee with. Stick one in each nostril and pinch the nostril closed to hold the stick. Walk around the room briskly breathing through the swizzle sticks. That is what you would be doing to your dust collector. It can be done but slower. If you are smaller it is easier so if the dust collector is smaller it would be easier than if it were large.

Thanks guys. I planned to build a floor sweep out of PVC but didn’t want to drag a 4” pipe around the shop if I could get away with using the hose I already had. I’ll rig up a quick adapter and see how it goes.
