Re: CFM and RQ Gaps
I have a few questions about the cfm...is there a certain point
where you're moving too much air? I've seen air compressors run on
blast gaps before, and I'm using a squirrelcage blower at some
obscene cfm, and have found an even more powerful blower from an AC
air handler (for such a small motor, fan, and enclosure it moves a
*LOT* of air...and I mean a *LOT*..came out of a 3 bedroom house's
air handler...it's free, so I'm out no money on it, but I do wonder
if there get to be a point of "too much air"...
Just wonderin', and I'll of course hook it up for myself to check
and see ;) I s'pose the best way to find out is to hook it up and
find out :))
