Certainly the results could vary depending on the application, but we felt this was a great way to show before and after performance.Īs stated above, we used fleece bags in all of the dust extractors as the primary filter to prevent premature clogging of the pleated filters. This helps show the potential performance in a real application. 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. Each dust extractor was equipped with a filter(s) and a fleece bag (without a bag the filters would clog very fast, and we always recommend using fleece bags on the jobsite). Using Fleece Bags as Primary Filterįor the air volume, suction, and airwatts measurements and calculations, testing was done with clean dust extractors as an “out of the box” baseline. We know you have lots of places to get this sort of evaluation of tools, but we think ours are the best based on our vast construction experience. Each of the guys on the team is a contractor, a PRO, a guy that actually uses tools every day to make a living. Ergonomics and Features – We ranked each vacuum in categories including: Canister handles, wheels, locking caster feature, accessory attachment, hose attachment to vac, ease of controls, auto-clean switch, power broker switch, maneuverability, hose storage, cord storage, cord length, hose features, ease of filter change, mess changing filters without fleece bag, compactness, and weight.Īll of these tests and evaluations were performed by our Tool Box Buzz Team of contractors.Noise – Decibel measurements including the average and maximum value under high load.Airwatts was calculated for both the clean and dirty filters/fleece bag. Best indicator of the overall relative power and efficiency of the units because it takes into consideration both the water column and the CFM factors. Airwatts – Calculated standard measurement used in the vacuum industry.This test was conducted twice, once with a clean set of filters/fleece bag and once with the dirty filters/fleece bag. We also tested suction with a meter to compare the results to the water column test. Suction (Water Column) Test – This provides a relative measure of the motors suction power. ![]()
