I’ve never had dust collection, watched some videos so I have a basic understanding but I’m not sure which unit would be best for me. I’ll be venting outside so I shouldn’t need to mess with filters and I’m planning two runs, one about 20 feet with 4 drops and blast Gates and another about 15 feet with 2 drops and blast Gates as well. These will be straight runs at 90 degrees to each other. Collector will be in the corner. I’m considering the harbor freight collector and basically scrapping the bag filter. I’m planning a 55 gallon drum and a cyclone for chip collection. Thank you.

I have 2 of the HF units, both venting directly outside and they work fine; one has a 20’ run with 2 machines and the other has a 12’ run with 2 machines; living in the country does have its advantages

That it does! We were lucky enough to find a place with no visible neighbors and a 30×40 shop. We just had a heater and a few more outlets installed. It’s only 2 acres but the freedom is amazing. Are you happy with the harbor freight model? I suppose I could do two as well maybe share the same chip collector? Not sure what to do with the table saw, I don’t like the idea of tripping over a hose or having one drop from the ceiling. I was thinking a shop vac and setting it up with a separator. I’m planning a big assembly table/out feed table for it.

I can’t say how well this will work for your situation, but I’ll describe mine a bit as it works quite well for me. I bought a Oneida Air Systems Mini Gorilla dust collector a couple of years ago and really like it. My shop is about 30×30 and I have it outfitted with a table saw, band saw, jointer, planer, drum sander and belt/disc sander. I never run more than one tool at a time with my dust collector so I have a 15 foot, 5-inch flexible hose connected to the Mini Gorilla with a 5” x 4” reducer on the end. I swap it between tools as needed.

That takes a bit more work but not enough to be a problem. I rarely need to move it more than a foot or two when I’m emptying its bin. Other than that, it stays pretty much in one place with the hose running to the tools as needed. The hose does run across the floor, however, which I think is the most significant downside to this setup. That’s not a big deal to me, however.

I like the canister outlet filter. The cyclone does a very nice job of separating out chips and it takes on everything any of my tools can send its way. I think the planer challenges it the most and it keeps up very well with that, even with more aggressive cuts.

I’ve been happy with my systems for over 2 years now—-of course I would like one of the fancy, overpriced models that would probably suck the life right out of my shop but I feel good about my less than $400 systems

You mentioned that you just had a heater installed. Remember that when venting outside, your heat goes out with the dust. AC too, if you have it. I don’t understand the outside venting that many posters want to do. If you are collecting the chips inside, the DC is inside, what is the gain? I converted my collector to a Jet pleated filter, and really have no dust. I added a Wen air filter for my hand sanding dust. My 2 HP machine has about a 70 db noise level venting inside. I used 5” steel duct.

When you say chip collector, are you talking about a cyclone? I cannot seen any point of having 2 DCs going through the same cyclone. Usually the cyclone is before the DC impeller. On the other hand, if you are just going to put a bin of some kind outside the shop to collect the bulk of the dust that should be fine but just make sure that you can close off the one that is not in use so that it does not try to blow dust back through the ductwork for that one. Also, if you really are going to vent outside, you may want to make a weatherproof enclosure outside that can house the DC motor as well to get much of the noise outside too.

I need to do this cheap. I know bag filters aren’t very good and I can’t afford dust collector, pipe, blast gates, cyclone and an after market filter. Where I’m putting the dust collector there is an old door that I’ve insulated and closed permanently. If I collect the chips inside then vent outside through the old plywood door I don’t need a filter so I’ll save money which at this point is very good. I can barely afford the wood to do projects at the moment but the dust is driving me insane. One step at a time

Here is my favorite video of modifying the HF dust collector https://www.youtube.com/watch?v=0RAoj4urS-Y. I really like how the modified HF collector still only takes up about the same amount of space as the stock unit.

I realize all of that is out of your budget at the moment. However maybe it will give you some ideas on how you can set up your DC now so it does what you need but leaves room for modifications as funds become available.

Keep in mind that exhausting dust collection air outside will not only impact the ability to heat your shop (much like having an open window, which is something not very economical in colder regions), if you are using propane, natural gas or wood/coal for heating, you will also negatively impact the flow of the bad stuff (i.e. carbon monoxide) out of the building with the dust collector sucking make-up air through the heater exhaust. If you are using an electric or heat pump for heating, there can still be a lot of $$ flowing out with the exhaust over time.

I agree on avoiding the bag-type filters and after researching the options, I decided to wait until a canister filter unit was in the budget. I also wasn’t too keen on buying a HF unit and future upgrades.

It might be worthwhile to check out Facebook Marketplace and Craigslist for the option of acquiring a used dust collector. I was lucky and found a new 2hp Grizzly G0458Z Dust Collector with one micron canister filter at a great price. The seller had bought the Grizzly, but before assembling he bought a larger DC at an auction and the Grizzly sat in the corner of his building until he needed the space for something else. He posted it on FB Marketplace for $250 but when we arrived he wasn’t able to find some of the unassembled parts (while he was searching, I checked Grizzly’s website for parts availability and cost – $40) and when he wasn’t able to locate the parts he gave me the machine for $200 (I had the replacement parts installed less than a week later) and it has been a great unit. The Grizzly is $535 new (plus $99 shipping).

I had previously missed a good buy on a Jet DC w/ canister filter a few weeks earlier, so good deals do pop up. The key though is to do frequent and diligent searching because the best machines at the best price don’t last long (I had the Grizzly in my shop the same day it was listed).

My shop is in a 30’ x 40’ x 10’h building, though my woodworking area is basically contained in a 12’ x 28’ area with the rest reserved for my tractor w/ implement, equipment maintenance & metal / general working area and my pick-up when the space isn’t needing for larger woodworking projects. I have a Mr. Heater Big Maxx heater (propane) that does a sufficient job of heating, though it will be much better once I insulate the ceiling area (the only present insulation is 1/2” on the walls). I ran two sections of 4” PVC with two blast gates and flexible hose to my machines on each. I also have a Super Dust Deputy that I have yet to install in my system. I still use my shop vac / Dust Deputy for my sander, router table & scroll saw at my workbench / assembly area, though may plumb that into the main DC at some point in time.

You can use pleated furnace filters to make a filter box with them rather than buying a Wynn pleated filter. Vacuum it out or blow it clean every couple months. Then you can keep the hot or cold air inside your shop rather than losing it with the DC exhaust.
