Dust collector forcing chips to one bag1/24
Hello all. I've recently had an Extrema DC-3000 TYPHOON dust collector installed in my shop and I'm having issues with it forcing most of the chips to one of the far outside bags. It fills it up with all the fluffy chips and we have to empty it 10 times for ever one of the others and the two inside bags might get emptied once every other month. The manufacture has recommended reducing the air flow through clamping it down so I installed a 18" blast gate to reduce flow in the main intake line but that's not helped. Has anyone else had this happen? Any help would be greatly appreciated.
You can install your own baffles to force the chips into the lead bags. The bag closest to the inlet could have for example a 6" high baffle straight up out of the bag opening, the next opening could have a 12" high baffle and so on. Only the chips that are in the air space above the baffles will make it to the last bag.
The baffles can be as simple as aluminum sheet stock (flashing) tacked into place.
Thanks BH Davis. That's what I was thinking but I had an idea to have a metal guy bend me some say 18 gauge steel as tall as the steel barrel part that connects the upper filler bag and lower collection bag. Screw it to the sides to create vertical fins inside the barrel that would force the chips out of the air stream and down into the collection bag. I can't quite visualize the idea you have. Do you mean a piece of metal placed in a horizontal position inside the steel drum?
Sorry I wasn't more clear. What you describe is exactly what I meant.
Only thing is I would only do it from the bottom. Having the baffles hanging from the top is going to make chips fall down through the center of the air stream. This could possibly cause more problems. By putting the baffles only from the bottom, with the ones further down the air stream being taller than the ones closest to the chips inlet, you won't be disturbing the upper half of the air stream/chip flow. This will allow the bottom mounted baffles to capture chips and drop them into the bags while the chips higher up in the air flow just pass by. You can experiment with baffle height until the 3 bags are filling evenly.
I have a shop built system (due to low ceiling heights where it is located) and have done something similar to balance the 3-bag load. From my experience with this system I can tell you there is no perfect solution. Different wood species chips will have different mass and blow different distances. On average though our 3 bags fill relatively evenly.
Thanks. I'll give it a go and let everyone know what happens.
