Thanks!

That's probably because Ben has sourced them and probably has them for sale. Most people I know start with either an air powered venturi or a series of marine bilge blowers hooked up in series Or a dimmer controlled vaccuum or a battery powered leaf blower...  Lots of work arounds. If you check out www.driveonwood.com you can quiz the brain trust there for free and read most posts. there is a paid section but if you are building an imbert style downdraft unit like Ben's style those threads are all on the free side...

Thanks David. I am building the unit in Ben's book. I don't think he still sells the blowers. I've been to driveonwood, but I'm still looking for specifics--either names/part numbers of the exact units people have had success with, or at least a number for CFM, RPM, lift, etc. Finding high-suction blowers in DC is tough. That said, since I'll be using my gasifier to power a genset, I don't see why I can just use an AC unit with 20 inches of lift.

Thanks Anne—very helpful explanations!

I’ve been scouring this site to try and figure out what these titles mean—pollinator, steward, gardener, etc. They seem to correlate with the number of posts someone has made, but I’m sure there’s more to it than word count. Can somebody direct me to the page that explains this?
