We know: You’ve seen dozens of not-inexpensive dust collection vacs, and if you can’t afford one, you’ve probably managed to throw your own together with an auto switch and shop vacuum. So why tell you about this new one from DeWalt? Answer: It cleans its own filters.

Every 15 seconds, this vac pushes a pulse of air back through the filter to dislodge any dust buildup. Theoretically this lets you keep on cuttin’ (or sandin’ or…) without stopping to bang on the filter. Besides auto-clean, it’s a standard, pretty powerful vac, delivering 129 CFM via a 9 A motor. It weighs in at 32 lbs, and DeWalt claims the filters are 99% efficient. (We note the absence of the word HEPA, but then again your home-built solution isn’t HEPA certified, either.)

Expect to shell out around $550 for one.

    While I wouldn’t turn down receiving one of these I dunno if would spend the premium for self-cleaning. I own a Dust Deputy from Oneida and it really cuts down on the amount stuff that makes it to the vacuum. Keeping two cleanstream filters on hand makes it not too terrible to always keep one clean.

    seriously—-this is a PC vac painted yellow. Just look at it.

    Nothing new here…..move along.

    With Stanley having aquired B&D – I bet we’ll see even more rebranding. They’re putting the Bostitch name on Fat Max products and B&D was already blurring the lines with PC, DeVilbiss, Delta and Dewalt. From my consumer’s point of view – I wouldn’t mind seeing some rationalization take place so you could gage where each product line was targeted and what you might expect in terms of performance and features. I’m guessing that some marketing gurus (maybe left over car salesmen) have the notion that the more distribution channels you have – with as many cosmetic-only differences you can think up – the more you will sell. Anybody still want to pay a high price for a Cadillac built on a Chevy chassis?

    From my experience, a backwards puff every 15 seconds won’t do much beyond provide a placebo effect. A long time ago Sears made a vacuum with a ratchet that you could crank to dislodge crap from the filter when it was turned off – it actually worked fairly well so we bought a few for our service techs. Next year they were discontinued.

    Why not just get a dust deputy or make a Thien lid and forget about spending $550? You can take a $60 shop vac and turn it into a dust collecting beast without having to skip a car payment.

    Like all shop vacs, what I look at first is how LOUD they are. Some can be deafening. Others only slightly less so. Does anybody know of a good vac with a 2.5″ hose that won’t blast your eardrums out?

    We’ve been using Fein vacuums for several years in situations where noise is a big issue. You might take a look at them – not perfect – and a bit pricey – but quiet.

    I’ve used the hilti iteration of this vacuum while hooked up to my concrete saw and the filter cleaning works way better than I thought it would. Works awesome for cutting up a section of floor in an area where you want zero dust.

    I don’t have much to compare to other than an older Craftsman but I like my Ridgid with Scroll Noise Reduction. It doesn’t have the whine of my Craftsman. I managed to get a SS version on clearance a year or more back for like $99 at HD. Unfortunately I can’t give you solid numbers which of course would vary depending on how close you hold the mike. You might want to see if any of the woodworking magazines did a round up. If you use the vac as tool hookup definitely get a tool activated outlet so it only is on as long as you need.

    I assume DeWalt is releasing this in response to the new EPA guidelines imposed on contractors, so expect it to be HEPA certified. I have already seen several other vacuum companies, many I have never before heard of, that recently hopped on the EPA/HEPA marketing bandwagon. Fein looks to be most aggressive so far.

    Although I am not one of those Fein or Festool junkies, I will say that those (along with Alto) are the benchmark when it comes to dust collection vacs. At $550 it costs more than Fein or Festool. Is a china made Stanley/BD product really better than it’s German competitors? Most tool rankings put the Porter Cable version in the bottom of it’s class so I assume the DeWalt version would be right next to it.

    The only upside I can see is that it has some sort of storage and good looking wheels both of which are severely lacking in most vacs, including the Fein.

    If you are a pro still using a Craftsman/Ridgid/Shop-Vac you need to give one of these european vacs a try; they are certainly worth the investment.

    I’ve been taking a closer look at the Festool model since I became a little fanatical about dust collection recently.

    When the argument is framed in the manner of ” Does $500 seem like a lot of money comapared to a hospital stay due to pulmonary failure form wood dust infection?”, the choice seems logical. But is everyone destined to have a serious infection issue with sanding dust?

    Bill Pentz’s website is a well written and researched and certainly expresses his history and experience. I’m still trying to sort out how much is solid technical information and what part is paranoia? One thing is clear. I hate coughing up sanding dust. Anything that makes sanding a bit more enjoyable and clean makes me take interest.

    The Festool unit CT22E is HEPA rated and filters to 0.3 microns, which I guess is the HEPA spec. The Festool has a manual cleaning T handle that you exercise back and forth from the back of the unit. I’m not sure how often.

    I can’t say I would pay more for a Dewalt version. The pricing does seem off. I think the Dewalt D27905 is being marketed at a street price of about $430 (Grizzly Catalog). The HEPA filter is another $100.

    I bought a Dewalt DC500 for $100 and it comes with a HEPA filter cartridge. I sent an email to Dewalt asking for a rating on CFM. They responded that the unit is not marketed as a “dust collector” and therefore does not have a CFM rating. A rather odd and dodgey answer in my opinion. It does connect nicely to my Dewalt orbital sander and with a wall mounted switch I can auto switch the vacuum with my sander. A poor man’s version of the fancy tool port HEPA vacuum I guess. I’m sure it pulls less air than a 130CFM (Festool or Dewalt) “Dust Collector”. However, it is much less noisy and irritating than a shop vac and the hose is flexible which allows a more ergonomic operation.

    Thumbs up to Toolmonger for reviewing an interesting tool!

    Cool idea, but for half the price I can get a good regular shop vac and a dust deputy and have it last a long time between filter cleanings.
