For the vs3-72 Jeff is recommended the following:
MagDrive 24
BlueLine 40HDX, and anything larger
Little Giant 4mdqx-sc, and anything larger
Iwaki 40rlxt and anything larger
PanWorld 40X? and anything larger
Anyone with a 72" have input? Thanks!
I don't have the 72" model, but I would suggest a pressure rated external pump that is capable of at least 25' of head
Sorry guys, Jeff, not Ken. I was thinking today that at one time I had a Dwyer Air Meter for testing amount of air drawn while making mods to my old skimmer. I dug through my fish stuff when I got home and sure enough, still have it. I will run some tests and see what these pumps are pulling for air. I know there was a certain someone back in the thread a ways that was oh so curious to know. Will be interesting to see what each pump pulls.
I don't want to open a can of worms, but, I also thought that a while back we established that air draw and venturi skimmers, or air draw in general is somewhat of a gimmick..? :hmm3:
I'd be curious to know the air draw on an 800gph pressure rated pump vs non pressure rated pumps with 1200+ gph.

From everything I have seen and read there is more going on than just shoving a ton of air into these for sure.

On the VS3-48 here's what the air draw was with the Mazzei 1078;
(I've added some pump specs here in blue, I can never remember which one px vs. pxx, etc is.) :spin2:
Panworld 100PX-X = 16-18 scfh Max flow= 1270gph, Max head = 13ft.
Panworld 100PX = 25-28 scfh Max flow = 790gph, Max head = 21
Panworld 150PS = 40-45 scfh Max flow = 1100gph, Max head = 28ft (Too much air for the body)
All three readings were from a Dwyer RMB-52 air meter.
Looks like the more pressure the better.
These skimmers (36 and 48") seem run best with 16-22 scfh IMO. The foam head is really dense with this amount of air. Around 25 scfh and over not that dense, more wet skimming which is not bad either. Over 25 it seems like it's too much. Like ken6217 stated, balance is the key.
