OLD Laser Fume Extractor windspeed reading
The Anemometer reads 12.4 m/s through a 4" duct for our old fume-extraction unit.
That's 2441 ft/min * (0.08727 ft^2) = 213 cubic feet per minute for our little Epilog Helix. Not bad, but certainly not great. It's plenty for the small, well-focused volumes in this little laser, but nowhere enough volume to filter out the new large 4'x3' laser!
