I thought I'd make another thread to discuss testing my G0443 with a hot wire anemometer.

First, I'd like to thank John Lanciani for the gracious loan of his equipment. I've treated it better than I treat my own tools, and I'll have it back in the mail ASAP.

Second, some discussion about the setup. I've got a G0443 that I vent to the outside. Testing with the filter installed did not show much of an improvement with venting outside, so I'm not going to hook up the filter again for these tests. All the ducting is 6' 26 gauge sheet metal ducts, as well as the connections to the machines themselves to ensure maximum performance. All duct seams have been coated in mastic to seal them. In most cases I've stretched out any bends to be ~5' long, rather than two short 90s. The longest run is to the SCMS and jointer at ~45', where it runs across the shop, down a wall along another wall, then up.

For the purposes of this test I did not test the 4' drops of which there are a few, all very short runs. Previous testing has shown those get a bit squirrely, and don't necessarily reflect the ability of the DC.

I have not taken any of the piping apart, and I don't intend to do so. Outside of that, I'd be happy to do any re-tests for those who are skeptical of my results.
