Erik – All good points, but as we pointed out we’re not a testing laboratory, we’re all contractors with full time jobs. TBB based our overall performance measurements on Airwatts. What most folks don’t see if the amount of time that goes into these tests. The downside to the Ermator is weight, 65 pounds compared to 31 for the Dustcontrol. The constant in the equation (0.117354) makes the calculated result, over a wide range, come out to where one airwatt is roughly equal to one electrical watt. Nilfisk is the original equipment manufacturer for a number of the extractors in this test. Those who are concerned about noise should consider the length of the hose supplied with a vac, or shop for a long hose they can connect. This is a major issue of health and safety. And far more important. The vacs all seem to have about the same wattage blower. We needed two test jigs built  – one to produce inches of water column (S) and one to give us airflow CFM (F). Select to compare. Yes the filter is what removes the dust. Use a piece, If you didn’t see our post a couple weeks ago ex. For the baseline clean dust extractors the top three included: After sucking up the drywall compound the top three remained the same with: Interestingly enough both Hilti and Festool recorded slightly higher suction values in the dirty configuration. Obviously, the older the filter the performance will drop off…but autoclean features have drastically improved that performance for longer periods. Great job.

I have a thought for the scoring system, you mentioned being open to changing. I use Pulse-Bac and would never buy any of the brands you have tested after buying one. The gents at TBB did a great job of doing a relative comparison of several popular units. Then add up each category turn the test results into percentage based off of closest number easily usable. We have not reviewed the smaller ones. As noted, the data from this review provides the CFM at effectively no static pressure and static pressure at zero CFM end points, but almost no data about the vacuum curve in between. The Bosch GA50DC Dust Collection Attachment works with most Bosch 4-1/2 In. I was thinking of buying the Fein turbo II for home. Agreed that would be a cherry on top. In the other opening is a very small wire that is heated up by a power source in the anemometer. Not to mention the original vacuum to automatically back pulse filters clean while working. Below is a chart showing current pricing (at the time of this publication) for each of the dust extractors that we tested.

Would you show us where you got the information that the Makita’s specs are made at the hose end? I would have liked to see an orbital sander test done as well. The 10x vs 20x issue is largely due to energy formulas vs voltage formulas. For each dust collector we also measured the noise in decibels. We ask them their thoughts on our testing approach, and try to get their consensus on our approach. I would also very much like to know this too. Below is a table with all the results from each category. Were these done with auto clean on? Voltage measurements (iirc, this is usually what sound is measured at, dBa; xdb/V, or whatever unit of voltage is used) is a 20x discussion, with power doubling every 6 dB (again, that is a relative measurement to a baseline — not an absolute number). The formula for this ASTM standard is: P = 0.117354 x (F) x  (S). We chose Airwatts because it is a result of both suction and airflow. As usual, the top three tools were extremely close and rightfully so as they are excellent dust extractors. To accurately measure the air volume (flow) through the dust collectors, TBB used a commercial Dwyer hot-wire anemometer. When I started working with RF electronics years ago, it took a long time to wrap my head around the terms used with decibels (a tenth of a Bell — in honor of old Alexander Bell). Using fleece bags increases the life of the pleated filters (they cost far more than the fleece bags), increases the life of the motor, and makes cleanup easier and safer for users. It this case, you’re the account manager of the company you just claimed to be the best, as stated on your LinkedIn profile. and 5 In. TBB constructed a jig to hold the anemometer probe in the center of the airflow to consistently test units. I have had difficulty finding a hose adapter.

Angle Grinder Concrete Surfacing Attachment. Earlier, William Anderson asked about air quality. During the CFM test, we placed a decibel meter in the same exact location (we placed tape on the floor so the supporting tripod was in the same location) for each vacuum and measured the average and maximum decibel level. Jon. I agree with Fan Guy about testing with a smaller diameter length of pipe at the end of the hose. ... Small Angle Grinder Dust Collection Attachment… I’d really look close at the Hilti extractors. ), Ideal test would adopt methodology as Fan Guy suggests, but with data points for multiple orifice diameters in order to chart the relationship between CFM and static pressure across the potential operating range. *included accessories* – the Hilti comes with the hose, a basic filter, a single plastic bag, and that’s it. The CFM measure is a quasi-open flow condition (#2) with nearly zero suction pressure and maximum flow. I have yet to find an objective comparison point between a standard wet/dry vacuum and dust extractor. They are designed to filter out extraneous noise while transmitting speech. In the second round of testing each dust extractor was used to suck up 20 lbs of drywall compound powder before performing all the measurements and calculations. It’s worth pointing out that the total cost may be a bit deceiving, especially with companies like Hilti and Festool that offer robust warranties.

Divide cfm by 2 to create score(Creating %)… Example. Our tests were conducted at the opening of the canister with a fleece bag and standard filter attached.. Our testing was done consistently for each unit and provides a more realistic measurement during actual use. What should be done to compare “useful” flow is to use a tube with a sharp edge orifice that has a smaller diameter than the tube. TBB data cannot be used for any compliance determinations. Aidelife Angle Grinder dust Collection Attachment, Cutting dust Shroud 4 inch to 5 9.8 9.3 9.9 2: So the test is not really comparing apples to apples per say? OSHA’s respirable crystalline silica rule, which affects 2 million construction workers who drill, cut, crush or … The sound meter was 24 inches away from the units. Festool might be expensive but they also hold value better than any other brands. Our research led us to an industry standard of Airwatt as the objective criteria for overall unit performance, as this unit of measurement is dependent on both pure suction power (measured by inches of water column) and air flow (measured by cubic feet per minute – CFM). The trouble is, what we feel are good tests isn’t what others feel, and at the end of the day, regardless of the system we chose, everyone will rank them differently.
