J. Phil Thien's Projects

Retired,
I built the transition eccentric, but because the dimensions at each end are close to the same, it's a bit tough to determine that it's built that way.
I built the seperator to an existing drum that I had sitting around:  ~16" diam.

Not sure I'm smart enough to understand all of the science of this, but here's what I did:
-I built my separator using a scroll inlet, allowing for a 4" round inlet on the side, 2" offset scroll, with a 4" outlet in the top.  With pipe hooked straight up to the 4" round inlet, I was getting lots of bypass.
-Then, after reading thru some of Bill Pentz's articles, I decided to build a round-to-rectangular transition piece.  Following his instructions, I built a 12" long x 4" round to (in my case) a 2 3/4"w x 4 5/8" h rectangular transition.
-After installing and using it, there is very little-to-no bypass.
I'm not even sure what/if I did correct, only that it made a big difference.
Hope this is helpful.
Thanks,
Rick
