Compact Power - The Wall Mount Dust Collector
posted on August 15, 2008 by Rockler

Last week, we introduced Rockler’s Dust Right dust collection components. This new system of integrated fittings and attachments is designed with the hobbyist woodworker’s dust collection needs specifically in mind, and we think has the potential to become the standard in smaller woodshops everywhere. This week, we’d like to direct your attention to the Dust Right system’s perfect companion: The Rockler Wall Mount Dust Collector. This portable dust containment solution offers true dust moving power in a uniquely compact and affordable package.

We say “true” dust and debris moving power to emphasize an important point, namely that a dust collector and a shop vacuum are not two “sizes” of the same thing. In a quest to find an affordable, compact solution to their wood dust woes, woodworkers time and time again test the fact, only to find that even the best  shop vac simply isn’t up to the task of keeping up with almost any piece of stationary woodworking equipment. 

The reason is a matter of physics. While these two types of machine do essentially the same thing, they do it in fundamentally different ways. A vacuum is designed to create a high level of suction – enough to compensate for a low volume of air movement and sufficient to keep small amounts of debris moving through the narrow space of a vacuum hose. By contrast, a dust collector uses a powerful induction motor to move comparatively huge volumes of air through much larger ductwork or dust collection hose at a sufficient speed to keep dust and debris aloft and on its way.

But there’s more to it than that. In designing dust collection systems, woodworkers confront another bare fact of physics: the effect of friction on air movement. Long runs of ductwork, changes in air flow direction and steps down in the pipe diameter can quickly reduce a hefty volume of air movement to a trickle. The answer in commercial shops is simply to design a system of ductwork as logically and efficiently as possible and then throw at it whatever air moving power is necessary. Not all of us have that luxury. With steps up in air moving capacity come commensurate steps in cost, electrical power requirements, noise, and demands on precious shop space.

Instead, many small-shop owners opt to bring dust collection to each machine only when they are using it. Hooking up to each machine individually using a shorter, single run of dust hose allows them to use a smaller, less expensive portable dust collector, without sacrificing the air volume necessary to service stationary woodworking equipment. In exchange for the small amount of work involved in moving the dust hose connection from tool to tool – a task the Dust Right system greatly simplifies – they are rewarded with more shop space, less cost, less noise and reduced power demands.

The Wall Mount Dust Collector is simply the next step in this move toward compact, efficient dust collection. At 50 lbs. it’s one of the lightest on the market. Its low-profile wall mount design gives it the smallest footprint attainable for a machine powerful enough to service typical stationary woodworking tools. In a typical hobbyist woodshop, the unit is more than up to the task of servicing a core group of tools from a single up-and-out-of-the-way location. Given reasonably short runs of  4” dust hose, its 650 cfm capacity will provide ample air movement for all but the most industrial-sized power tools. And for larger shops or more remotely located tools, a tool-free z-bracket mounting system makes moving the Wall Mount Dust Collector from location to location not only possible, but a simple matter.

Together, the Wall Mount Dust Collector and the new Dust Right system of components make up an ideal dust management system for smaller shops. With the Dust Right’s tool-free dust ports, moving dust collection from one machine to the next takes only a couple of seconds. An integrated floor sweep and bench nozzle let you apply your dust collector’s powerful air moving capacity to the shop floor and other surfaces with equal ease. And with the wall mount Spring Clips included in the Dust Right Master system, you’ll be able to keep the whole works up organized and out of the way.

Better still, you can have the whole system – the Wall Mount Dust Collector, hose and a complete set of Dust Right components – for less than you could easily spend on a dust collector alone. Together, the Wall Mount Dust Collector and Dust Right system are our answer to a call for a dust management solution that makes sense for small woodshops. And considering cost, versatility, compactness, and self-containment, we feel confident that we’ve met the challenge with exceptional success.

    Has anyone done an estimate of CFM with this if hooked up with the trash can cyclone lid? At 650 cfm out of the box, I first assume that the specs are without hose or bag, right?

    Thanks for the comment, Rick, and your patience (we wanted to confirm that we had correct answers before responding). The Wall Mount Dust Collector was tested using a method common among several manufacturers. It was tested with both a 5 and a 30 micron bag attached, and a length of straight pipe attached to the inlet. It exceeded the 650 CFM rating in both tests.

    It has not been formally tested in use with a separator, but if you'd like a few candid opinions of how it works out in general, you'll find some great information in our customer reviews: http://www.rockler.com/product.cfm?Offerings_ID=21255&TabSelect=Reviews.

    That's great information, THANKS!! There were no reviews with anyone using a collector (unless I missed it). I'm trying it out, and trying to figure out a good place for it.

    With the separator (cyclone lid), it doesn't seem to have any more suction than my shop vac. But even so, if it were the same suction power but with a bigger hose, wouldn't that mean it's still moving more air, and therefore more dust would be collected?

    Thanks Rick - glad the information was helpful. No, unfortunately there aren't any reviews describing how the unit works with a separator. We thought that you were deciding whether to buy the dust collector, and might want to know how people like it in general. But it sounds like you're way past that. In answer to your question: yes, that's right. The more air volume/bigger the pipe, the more debris that can be collected. Even really good shop vacuums are rated in the 100-150 CFM range. So, even with the drag that the separator puts on the system, if the air is still moving fast enough in a 4" pipe to keep the chips moving along, you can bet that you are moving much more air volume than you would with a shop vac.

    I have a small shop and have been doing some research on the Wall Mounted Dust Collector. It seems like a good option for my small shop me but since my shop is in the basement I am interested in the sound level on this unit. I have not been able to find the sound rating (db level). Could you post that information? Thanks.

  • Rick Roades

    Jim - personal experience...

    I use mine moving hose from tool to tool, and I ALWAYS use a set of headphones/ear protection. The motor on the dust collector along with the tool, be it table saw, etc., are way past real safety limits. Even the router table or table saw (I have a bosch 4100) are above safety limits for long term exposure.

    I don't know the exact decibels of the DC, but a recent article in one of the trade mags put the decible level of the Bosch table saw at about 92 db. In a small space, that puts both tools almost next to you. Please use ear protection. Regardless of which DC you choose.

  • Rick Roades

    One last revisit to CFMs...All but one of my tools use a 2 1/2" dust port. I've put a cone shaped reducer on the 4" hose to minimize loss of air flow, as opposed to the 2 1/2" connector Rockler sells to reduce, because the inside diameter is actually smaller than 2 1/2". With the Wall Mount DC on, the 2 1/2" intake has less suction than my shop vac. Since the intakes are the same size, wouldn't that mean that more air is being moved by the shop vac? Even with a separator on the shop vac, the suction is greater at the end of the hose. I would keep the Wall Mount for future use and general cleaning, since I have it.

    Rick, thanks for the question. In general, it works like this: A shop vac has more power to overcome drag on air flow - small diameter hoses, the ridges on the hose, tight turns in the hose, etc. A dust collector, on the other hand, has the capacity to move a much greater volume of air, but isn't as good at overcoming resistance. So it's possible that there's too much drag on the system. A separator creates resistance. To compensate, it's good limit other sources of drag - keep the runs of tubing short avoid sharp turns, etc. There also needs to be a supply of free air at the tool. Plugging up every possible inlet for air except for the slit in the throat plate of a table saw, for example, will not make matters better. A filter bag that's plugged with fine dust can create problems as well. It seems like you should be getting better results that you are. Are there modifications you can make to limit resistance? Please keep us posted.

  • Craig Harvey

    So, has anyone ever come up with the decibal level for the wall mount dust collector? I would like to invest in one, but I would like to leave it running between cuts etc. ---- Using earplugs during the actual operation is fine but would like to remove earplugs between cuts and leave the dust collector running. Since the shop is in my basement I wonder about the nooise

    Thanks for the question, Craig. The Wall Mount Dust Collector has an approximate decibel range of 80 - 85. That's fairly typical for a dust collector. City traffic noise is often used as an example of that noise level. For another comparison, a budget shop vacuum can be as high as 90+.

    I use a similar sized collector with a 30 gallon metal top fiber drum from Uline.com. This combination is about the same HP as the Rockler unit. The air flow is terrific with a #30 filter bag. I can testify that the combination keeps up with every machine, including those that require a 2.5 inch reducer. This includes a Makita 12 inch planer and Powermatic 6 inch jointer, plus table saw, sander and router (table). I tried using a trash barrel, but I could never get it sealed very well and it reduced air volume. But with the 30 gal drum, the air flow is tremendous and dust collection is way better. Too bad Rockler doesn't stock the fiber drums, but Uline does for about $50 bucks. They also have larger fiber drums for a much larger shop than mine. What makes them work so well is a locking ring for the top. I use Rockler's Dust collector components for the in-out ports on the drum. I didn't realize Rockler had this blower when I bought mine.

    I recently installed the "dust right" system and it works fairly well. However, the 4" flex hose has torn twice in a very short time. Twice at the dust collector and once at the handle.
