Hey Bro....I`m not familiar with any inline fans other than vortex , so maybe Mr D`ll chime in......but......Back at it tonight. Dire Straits for a while tonight with my medicine.
Picked up a good selection of shims and will get the floor joists in their final positions tonight. The type of concrete pillar that I'm using is very forgiving. I'll just shim a bit and then quadrupple check my floor slope. I want the slope of the floor such that water will always drain away from the two sides near the house toward my new sump.
Going to hopefully get this floor insulated and installed soon!
BTW - Mister_D and DHF - I listed 12" wind tunnels in the drawing. I intend to put whatever fans I used in the floor and sound proof them, isolate them. I can use 12" or 10" and whichever brand you two feel is better. I've read that the sunleaves wind tunnels can be encased in foam to make them very quiet. that is why they are listed. I'm not married to any mfr. tho.
Best All -
peace out
Interesting dig we have going on here...
