The Wolfbox earns its win the honest way: it ignores
the RPM arms race and simply moves the most air — 73 CFM, 334 grams of
force, past 200 mph with a nozzle, and the fastest wood-chip time at 2.1
seconds. Dual batteries and five attachments round it out. At $90 it's
priced like the flagship it is, and it's also the loudest unit tested.
The AC-27 is the reason to read the charts before paying flagship money. At
$30 it finished the real-world cleanout just half a second behind the
Wolfbox, moves 36 CFM, and posts one of the strongest force numbers in the
group — its only serious weakness is a large stock nozzle that blunts its
close-range speed. The Duort is the specialist pick:
the fastest bare-outlet speed at 133.8 mph in the lightest body here, but
with an 8-minute rated runtime and no nozzles.
Across the board, treat spec sheets in this category as fiction: all
fifteen dusters measured below their RPM claims, some by a factor of four,
and the measured champion (Mershgaya, 130,000 RPM) still lost the cleaning
race to a unit spinning at 24,800. The good news is real: the top five
units genuinely replace canned air — nine beat it outright — and can handle
jobs like drying a car that no $8 can ever will.
