Techno CFM test

[Padden McFadden]

Joe Brister lent me a gauge to do a little 4 to the door cfm testing. Here is a short clip.

what was the cfm hard to see the meter?

Sorry about the glare, if you look close you'll see it was reading between 261 and 255. The average was 257. I did several tests and they all were averaging around 257 cfm at 50 ft. And 248 with the inline filter.

Will that TM clean puke?? The video was neat, but the shakey camera had my stomach going...

Nice clean setup.

What size was the funnel opening you had the fan on? 3" or 4"?
