Looking for CamVac advice

[DavidR8]

Managed to get 90% of the ducting completed.
2-1/2 port for overhead collection off the Unisaw
The flex at the end will lead to a 6' length running to my drill press and provide a port for the hose from my tracksaw and router.

Crosses over the ceiling to a drop for my planer and for a dust shroud at my lathe. At the far end is another 2-1/2" port for my mitre saw and bandsaw.
With both motors running the collection off the mitre saw is excellent. I also tried the planer and hogged of 1/8" off a 6" wide board and it carried everything away no problem.
I'm very pleased with the performance.
(I just realized that I have the wye in the picture below upside down! Bugger!)

Alrighty, final installment on the CamVac saga.
After watching Dennis from Hooked on Wood build a baffle box for his CamVac I decided to do the same. I bought some 2" acoustic foam tiles and built a box from 1/2" ply to fit in the rafter bay above the CamVac. 19" wide, 22" long and 6" tall inside. Drilled two holes for the 2-1/2" hoses and one 5" outlet.
Got it mounted and connected the hoses.
Some levels:
As delivered and installed with the baffles: 83.9 db with a distinct whine
With just the hoses: 75.9 db with less whine
With the baffle box: 72.3 db with no whine
Very pleased.
