  • OT - Opinions on dust collectors

    I have decided that the shop vac just doesn't cut it anymore, and the wife doesn't like MDF dust all over her stuff in the garage. I am looking at getting a dust collection unit and was wondering if anyone has any experience with these 2 models. If the cheaper one will do I would rather go that way and put the extra $100 towards the next project.

    either one of these is better then shop vac but neither will filter out MDF dust a 100%. Friend of mine upgraded the upper bag on his model similar to your upright and it's working phenomenally. I'll ask tomorrow for the info.

        Tool King online and Woodcraft sell the upper bags for the vertical collectors. They're a micro-fiber type material you can launder. Woodcraft suggests using a plain plastic bag on the bottom for collection. Woodcraft gets close to $100 for the conversion, but I was there one Saturday for a demo on a Jet 2 HP collector and it did the job with a planer and a router. The horizontal units impellers take a beating, if they're build anything like the ones Harbor Freight and General Tool carry. The impellers aren't completely protected from debris. I got a vertical HF unit that had been dropped and bent-up. I hammered it back-out and it works, even though it looks like scrap metal. Be prepared, you'll spend as much for plumbing and ports/nozzles for your dust collector as the dust collector. I had 40' of 4" PVC sewer pipe left-over from my new sewer line and used most of it in my little shop.

          If you're using it for MDF, the biggest factor will be the bags as Roman said. Get some felt shaker bags from highland woodworking for the top and bottom. They're very affordable and they are amazing. Don't wash them though. The more you use them, the finer particles they will catch. They will also flow a LOT more air than the stock bags. The bags have so little air resistance that they won't even inflate fully when you first start using them.

          You may also want to think about a shop air cleaner to help with the finest of particles. Your lungs will thank you!

            The collection job will be a lot easier if you stop using mdf. Your're going to great lengths to reduce the mdf dust while missing the easiest part.

              +1 on the finer upper bag for MDF. And I would certainly go with a HF model. The key is not so much which unit, but how well you duct it and position the intake (if the tool doesn't have a fitting). Any air leak will cause a big loss of efficiency. If you are using it for more than one tool, and you have a work area that is dedicated (as opposed to one where you have to put tools away when you are finished).. it will be worth your time and money to "hard wire" your duct system. You can use pvc pipes and joints. Use gates that can be opened and closed on each tool as needed. Also give yourself a dustbin gate on the floor to sweep into. If you are primarily using one or two tools, I would go with a small unit that can attach directly to your saw or router, etc... and augment that with a cheap ambient filter. If you are going to be planning, jointing, etc. (making chunks as opposed to dust), you should get an attachment that goes in-line AHEAD of the unit to drop that stuff into a trash can before it can damage your fan. Like this:

              And I am just going to throw this out there: You should still wear a decent respirator. And hearing protection.

                I have a harbor freight 1HP and IMO its not that great. My wet dry vac is actually much better. But it is better than nothing and does cut down on dust in the air.

                  Thanks for the advice guys. Basically it will be used with the table saw and the router/router table. Looks like my best bet is the taller one with the better bags for dust control. I will start saving my pennies!

                    A friend of mine ordered a 10ft tall bag for his 2hp dust collector. The gain is a better filtration, increased air flow and energy savings.

                      Buy what you can afford now and upgrade along the way.
                      Look for a min. of 1-1/2hp. which is good enough for very short runs of duct. Roll it to the tool.

                      Also look for a model that can accept cartridge type filters. They are the most efficient at trapping fine particles. These work immediately, unlike fabric or other bags that rely on partial clogging to be close to as effective. The cartridges also allow more airflow over the useful life which is important for a smaller collector, keeps efficiency as high as possible.

                      A pre-separator would be the next addition. This will reduce wear on the expensive filters and save you from cleaning them frequently. Do a web search for "Thien Separator" and build that or buy one of the small cyclonic separators.

                        MDF really needs a lot of dust control from what I have found. I use a hood at the table saw blade, a 1hp cleaner with a pleated 1 micron canister, and a general air cleaner hung from the ceiling. This combination takes care of most dust in my small basement shop. Here are some links;

                          I have the Jet DC-1100 with a dust dog pleated filter but cut MDF on a portable table saw outside with a respirator. Everything gets blown off with the leaf blower before it comes inside. Same with routing and sanding MDF.

                            If you get a cyclone style separator inline with the dust system, you will pretty much remove 99% of the dust before it gets to the bag. Oneida makes a 4" inlet version. You could also make one DIY style. Plenty of Youtube videos on that.

                            I have the small dust deputy version inline with my shopvac and after emptying the 5 gal bucket its attached to three times, there is negligible dust in the shopvac.

                            I still wear some sort of dust filtration mask when doing MDF though, I didn't when I was younger and don't want to add to the damage. :-)
