Dust Extractor Testing / Evaluation
For the Dust Extractor Head-to-Head we evaluated the tools in the following categories:
Air Volume (CFM) Test – Tests the Air Flow volume of the unit in Cubic Feet per Minute. This test was conducted twice, once with a clean set of filters/fleece bag and once with the dirty filters/fleece bag.
Suction (Water Column) Test – This provides a relative measure of the motors suction power. We also tested suction with a meter to compare the results to the water column test. This test was conducted twice, once with a clean set of filters/fleece bag and once with the dirty filters/fleece bag.
Airwatts – Calculated standard measurement used in the vacuum industry. 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 was calculated for both the clean and dirty filters/fleece bag.
Noise – Decibel measurements including the average and maximum value under high load.
Cost – Current costs available online.
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.
All of these tests and evaluations were performed by our Tool Box Buzz Team of contractors. Each of the guys on the team is a contractor, a PRO, a guy that actually uses tools every day to make a living. 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.
