I was playing around the crown duct, and found a 360 outlet at the bottom performed a little better than just 6 outlets, but that was using 5015. The cpap style might be different.
I don't think the original crown duct can work with 5015/5020/axial. It needs some good pressure to perform. In stock form is lackluster with regard to flow. But no idea on it's effectiveness printing and at what speed. I may try a wedge design at some point, but I want to play with this duct a little. I have already added the 'valve' function of Valvnator and reduced the number of ports to 4. I need to find out how it flows 360 before I Can add more. In my mind, 4 is all that is needed + the valve slit.
@@MrRocksaltive used a similar design 360 duct with decent effect with a overvolted 5015 fan, but found the side directly opposite from the fan would still suffer when reducing the fan speed. Having a fan on both sides helped a lot. Might need to try it with 2x roborock cpap next.
Love the reaction
The joy in your voice!
Damn, nice performance!
Excellent results.
Thank you for the great video
You got super excited on this one. Cant wait to see your improvements!
Epic design!
It's awesome that a more compact duct gives such encouraging results ! It's probably lighter too, did you make input shaping comparisons ?
