Nic Obie showed several pictures of his dual configuration cyclone and Bill Pentz replied to an earlier query with this post. Awesome to hear from Bill pentz on this,he seems to be the authority on this.
"Dual Blower Cyclone
<hr style="color: rgb(209, 209, 225);" size="1"> <!-- / icon and title --> <!-- message --> You can use a couple of blowers to power a cyclone, but then should always check the motor amperage to ensure you are not trying to move more air than the motors can handle. Mostly this means blowers in series will burn up motors, so we have to put the blowers in parallel. To do this go from your main to a wye, then to each blower, then back to a wye. Jim Halbert did this ages ago and it worked fairly well, but he did have some motor problems, so please check.

I tried to do a search on this archive and the Badger pond archive (no longer exists) but this doesn't look as popular as I previouslly thought.
Bill, I don't see any alternate configurations like dual blowers on your site, would you know of any plans or test data for this type of setup?
Does anyone else have a setup similar to Nic Obie's dual configuration?
