very good article. Bigger is better until you get below that threshold. Id be concerned about velocity dropping too low and having dust settling in the line. Before I go looking for the pipe; does it come in 8 dia.? If 6 is the way to go why then dont the stores sell fittings for this size.go figure! Youll have to keep an eye on low spots in the line and disconnect after a month or so to see if you have dust settling in the line which can become a major problem over time. Hi Ted. Because of its smooth rigid interior and all-metal construction, hard fixed ducting reduces the risk of static electricity buildup and decreases static pressure over long runs. I have a 2Hp 1200CFM DC. Attach using 1-1/4 drywall screws. I have found this to be a perfect fit on both 4 and 6 ducting, requiring only a pressure fit to stay on, with little noticeable air leak. But I have a 2 questions; 1) If your DC intake port is roughly positioned in the middle of your wall, which way would be better to run your lines. The lack of resources on this topic is disheartening. Some of the cheaper stuff I have used is extremely rigid, making it terrible to work with.

Hi Ted. We are here to meet your needs. How to Size Dust Collector Ductwork? Most if not all collectors come with a warning like this. In a separate article I will walk through the dust collection design at each tool in my shop to help you complete your dust collection system design. Great article. I currently have a 4 H.P. Hi Paul- Good for wood dust, paper trim.
However, plastic flex-hose and plastic duct, are an insulator, and dust particles moving against the, walls of the plastic duct create a static electrical build. Very helpful as I plan out a system. Travis. Once it is started hopefully it will slide the rest of the way in without a problem.
Grounding your existing ductwork would not be expensive or time consuming. To maximize your air flow, focus most of your design efforts around 6 pipe, sometimes 4 when you need to, but nothing smaller than that for stationary tools. If it drags the air from the tool at the far end of the system it should be adequate to move the dust through the rest of the pipe.

Grounding PVC and Other Dust Collection Myths by Rod Cole: http://home.comcast.net/~rodec/woodworking/articles/DC_myths.html Source for those hard to find PVC fittings: http://www.pexsupply.com/PVC-Fittings-470000 Source self made blast gates: http://benchmark.20m.com/articles/BlastGate/blastgatebuilding.html Thanks, Brent, Hi Brent, I would be skeptical of a CFM rating that high on a 4hp machine, as many manufacturers use highly inflated CFM ratings which are probably based on a theoretical max, or something like that. 4" x 6" Industrial Dust Collection Reducer (Style 1), 5" x 6" Industrial Dust Collection Reducer (Style 1), 6" 30 Deg Industrial Dust Collection Elbow, 6" 45 Deg Industrial Dust Collection Elbow, 6" 60 Deg Industrial Dust Collection Elbow. So, you will have to make your own ports, and in some cases, cut holes in your tools to accommodate the port. If I have three separate lines, Id need a 6-4 reducer going into each of the three ports on the collector. So I wrapped a ground wire around the dust collector a couple times and grounded it. every thing that is in the article is great, I made my blast gates from wood and metal with no problems, I use a first primary collection container before my dust bag to catch larger items so they do not go through my dist collection fan and you do not have to empty the dust bag as often. I have emptied the barrel a couple of times and only have a trace amount of dust in the DC bag. Paul. It is easier to do it now rather than pulling your ducts apart later. This can also provide a nice cleanout in a convenient location should something ever get lodged in your ductwork.
Secondly, if you have a means of demonstrating the explosiveness of wood dust in simulated small shop ductwork, I would like to collaborate with you to produce a video on this topic if you are interested, as this would be received extremely well by the woodworking community. I have been using a central dust collector system for over 10 years, utilizing both PVC and HVAC ducting. That port allows massive air movement, and allows my dust collector to pull everything that is not attached to the tool. That way your investment is protected when you expand the system later, and all you need to buy are a bunch of plastic tubes and fittings. If that doesnt give you enough wiggle room you might need to either try different flex pipe that might have a different diameter. Determine the diameter of CFM requirements at machine one. In any case I am leaning heavily towards using PVC. Hi Jim. Even among standard promulgated by the same standards-developing organization, the definitions vary significantly.. So unless you can get your insurer to put in writing, that you are covered ~ ~ ~ ~ ~ ~ ~ ~, Is part 2 of this article out?
For instance, if the machine has a CFM of 395, 4" ducting will be required.
I know how much dust woodworking produces, even with hand tools, and I love to read and hear other ideas on dust collection systems. Would such a small system work, in your opinion? I encourage you to accept the fact that most tools come with insufficient tool ports. The more info about dust collection I can get the better Paul-WWGOA. You could configure a reducer and piece of 4 flex hose for 4 ports, and connect directly to the 6 ports with the coupler.
Happy Woodworking! Go for the bigger machine and pipe to each tool. IMPORTANT SAFETY NOTE: All dust systems must be grounded to avoid a buildup of static electricity in the ductwork or filter. I would either go all 4, or remove the 6x4x4x4 reducer and go 6 for your main trunk.
If you have made an investment in a powerful dust collector, that is a great first step toward creating a healthy shop environment. Tahnks for writing the article, it was very good for me. If there is emerging data in this area then I want to be informed, and I believe that there will be widespread interest across our readership as well. If you start dipping below 4000 FPM, you should reduce the size of pipe. The unit has lots of capacity, a very high MERV rating for the filter and low noise rating (75 dbA at 10 ft.). My shop is located in a basement and space is tight so I have to use the manifold. Return Policy |
Paul-WWGOA. As far as attaching the flex pipe to the coupler, I just tuck it inside and there is enough friction to hold it on place. We have provided solutions for these applications and many more. Installs in less than 1/2 the time of standard flanged duct systems. At his stage, I will probably purchase a 2Hp dust collector. The results were quite interesting when I tested before & after my Clear Vue upgrade: http://local.wordpress/articles/product-reviews/stepping-up-to-better-dust-collection/, Hi Paul; heres an update on my comment from a month ago. That tiny static shock you might feel is plenty to cause a cloud of dust to blow up. On the 4 it is a bit looser, so I have used duct tape to secure it.
When using the HVAC ducting I recommend taping ALL joints and seams as this reduces air leaks and improves preformance. If you end up with schedule 80 or even schedule 40 in an 8 pipe, it will be quite heavy and make installation a bit rigorous. If you have trouble slipping the flex tube over the PVC just cut some slits into the PVC as you see shown in the 2nd picture in this article. Use metal pipe with whatever fittings you choose to afford and make sure to ground it in at least one place. Here is an effective ways to make quick disconnect fittings for 4 and 6 PVC. Ive gone through the design calcs, and it looks like it will work with 4 ducting, but after reading this article Im wondering if he should relocate the DC to reduce the lengths. Because this type of hose has a rough interior and flaccid nature, it causes substantial static pressure loss resulting in higher energy usage which can affect system performance. What are your feeling? Any thoughts? I have a Clearview cyclone can I run the dust container off the bottom at a 45 degree to a barrel outside the wall, I would think so, but I would suggest contacting the folks at Clear Vue with this question to be sure. I would tend to dispute the 6 pipe and the theory of max air volume. Ive had to do this on some dust collectors. I would argue that many of the products that are sold in this category are not up to the task of removing. I searched the internet and read books to do the best I could and I see I managed to get some things right. Suggestions anyone?? Upcoming Events |
I have a radial arm saw with a 2 port so should I run 6 all the way to it. Did you integrate the switches in your equipment?
This was exactly what I was going to do until I put my lawyers hat on and started asking questions.
. Do you think that will have enough power? If you are getting this you will want to either upgrade your dust collector or replace the 6 with 4 pipe to increase the air speed. I slip the PVC over the small end, and then the bell slips over the dust port on the tool. All of our fittings are fully welded to eliminate leakage and give proper support that will last a lifetime. If you have a special requirement, please call us.
I do recommend a direct connection to all machines and a open connection to portable machines that are used sometimes. Manufacturer ratings for CFM are inconsistent, and if I know which machine you have Ill have better estimate of what kind of performance youll see through that configuration. Run hard pipe as close to the tool as possible, and use just the flex pipe you need for convenience in case you need to move the tool. Ive had a 2HP cyclone dust collector for years, its a collection of home improvement store galvanized pipe (probably a combination of 26-30 gauge, I never really check) and high quality smooth elbows and wyes purchased from a variety of mail order sources. We are very well versed in creating custom components to fit your every need.
New shop in new house, so I installed a Harbor Freight DC, Oneida Dust Deputy, 4 ABS for most of system, and a blast gate at each drop. Seal the joints? Watch the next newsletter for specifics on how I optimized dust collection at various tools in my shop. document.getElementById( "ak_js_2" ).setAttribute( "value", ( new Date() ).getTime() ); document.getElementById( "ak_js_3" ).setAttribute( "value", ( new Date() ).getTime() ); Enter in your email and password to create a FREE account, http://home.comcast.net/~rodec/woodworking/articles/DC_myths.html, http://www.pexsupply.com/PVC-Fittings-470000, http://benchmark.20m.com/articles/BlastGate/blastgatebuilding.html, http://local.wordpress/articles/product-reviews/stepping-up-to-better-dust-collection/, https://www.homedepot.com/p/7-in-to-6-in-Round-Reducer-R7X6/100117561, https://www.wwgoa.com/?add-to-cart-multi=1&products=1195090&skipcart=1&coupon=c20716&vscid=c20716&skipcart=1336083/?nabc=0&SubscriberKeyHash=, Woodworking Blog Posts, Articles & Videos to Build Your Skills. My guess is that a dust collector with a 5 inlet will not move enough air to maintain adequate line speed for 6 pipe. This will generally be referred to as Sewer and Drain, sometimes referred to as ASTM d-3034 or ASTM D-2729. The part left inside the ductwork is smooth and shallow and wont catch small pieces.
Thanks ! Be careful out there.
Love the system but for one thing: Insurance companies (Pretty sure every single one of them) will not cover a house fire if there is a non metallic DC system and they can claim that the fire started there. I looked thru your pics and text and dont see anywhere where you have 6 flex over PVC pipe, only inside PVC fittings. Our fabrication department is dedicated to producing quality products. This would be easily able to cause an explosion if the right amount of dust was floating in the air at the time. The fit probably wont be perfect, so youll have to adapt by wrapping with duct tape or similar. The Powermatic 73 is a 1.5 HP unit, which puts it right on the edge as to whether it will deliver enough air speed through 6 duct to prevent the accumulation of debris in the duct. Im planning to use 6 ducts to the tools, and 4 for the vertical runs to keep the velocity up.
check out grizley they have a very good dust pipe assortment TOP SHELF !!!!!!!
Would 2 PVC piping work when connected to a 12 gal shop vac? Privacy Policy |
Great advice! The real danger is having a spark occur at the same time. Without going on too long here, see the directions from Shop Fox above. If it is still tight you can warm up the flex tube a bit with a heat gun. The soap seems like a worthwhile trick to try. Do not forget to connect the, wires to each other with wire nuts when two branches, Ensure that the entire system is grounded. If you have any additional questions please chat, email or call us at 1-855-253-0822. Example: A system where the main trunk line is 6" in diameter (representing 615 CFM) is connected to a machine that requires 395 CFM (4" diameter), you would add 615 + 395 = 1010 which would require a 7" duct. Paul, I am also about to set up a 6 system. My question should I take advantage and use the largest duct I can find for the main then branch off of it with smaller ones?
Wish I had read a a long time ago.
I am in the process of setting up a new workshop and will be looking at a PVC rigid pipe system this time.
Can be taken apart and reconfigured quickly and easily. DC, with suction capacity of 3560 CFM and Static Pressure 16.8.
Thanks, one of the best and simplistic explanations on the web. To prevent static charge and shocks I lined the PVC and fittings with a strip of aluminum foil duct tape with the ends wrapped around the pipe ends and fitting ends so that continuity is maintained from the machine all the way to the dust collector which is electrically grounded. Run the ducting so that it ends directly above each dust port. Its probably no more expensive than plastic. How do you attach the flex inside the coupling? Add screws wherever needed to secure joints. All those wood shavings swirling in a plastic funnel was a wicked combination. Keep in mind the ceiling height, obstructions, electrical service, etc. Here is the experts response, thank you for the question: I havent tried it, but it seems like it might be too soft and could potentially collapse. Does that make sense? I love it! is this the maximum duct size that i can use or should i still use 6 for the main runs and 4 for the branches.

Im still flip-flopping over which piece of PVC (pipe or fitting) I want attached to the flex, based on what is going where in the shop and how much moving will happen.
A connection with pop rivets and a silicone chemical bond will make your system completely airtight. Whether you need an entire system or just a few dust collection components, we offer some of the most competitive dust collection system prices in the market to fit your budget. This process requires flanges to be fitted over each end of the pipe, the edge of the duct is then vanstoned to keep the flange in place, and lastly, flanges are bolted together to join pieces. Hi Frank, thanks for the kind words. If it is super tight I would cut a slit into the flex, cutting through a couple strands of the wire that wraps around it, and that should help you get it started.
