sorry i missed this question.
the dart cant push the bubbles down that long of a pipe with out the bubbles breaking and combining into bigger bubbles. even when its pulling air on its own the bubbles will combine. i had a super short piece of 2" pvc pipe on the end with a 45 deg fitting on it and the bubbles got twice as big as with out it. there is just too much air there and not enough water you need ot get the bubbles out of the pump and into the main chamber as fast as possable. the shorter the distance the less chance the bubbles will combine into larger bubbles.
ther reason air stone skimmers are still around is because of there effecient way of producing vast amounts of air in tiny bubbles, for little wattage. this is just the next step in making a more effecient skimmer design. more air for less watts, but also less maintaince too. air stones need maintaince almost every month to replace the stones. these pumps will run months/years with out major maintaince.

Well the number two impeller is made , Not going to put a center cone on this one , want to see if it makes adiffrence . There are 87 pins on this thing . Its a pain in the *** to cut all those pins ,but worth it .
I am overwhelmed at how well the nw works . Now I just have to get the body of the skimmer built . Should have it finished next week .

OK, tell us the truth, what's in the water? stresscoat?
Really, thats is truly awesome, foamtastic, it looks like another benchmark has been set. Now you no what you can use that 6'x6' cylinder for.
This wheel raises all kinds of questions. like zapata41 noticed. so the smaller dia needles and more space in between the pins.
how do you think that effect the performance?
what size skimmer are you puting that on? would controlling the rpm on that pump be a good way to adjust the output so maybe it can work on smaller skimmers without using valves?
congrates on the wheel good team work

Ima working on a wheel tonoght that has twice the number of pins .See howthat goes , IAm going to use two of these on my 25 inch tube to make a skimmer. I use a high tech , percision machined , chunk of two inch pve with a hole drilled in it fir the venturi . Took all of about 2 seconds to make , works good thou . Spazz shold be showing up tonight so it will be interesting to see what we come up with .
