Measuring fan static pressure experiment

post #1 of 34
Thread Starter 
I'm not sure where I'm going to go with this if anything, but I wanted to see if I could do it.

Most people refer to a fan's performance based on CFM, yet that's really no different than comparing pumps based on maximum flow rate only . As you know pressure is equally as important for the net result and a fan produces a curve very similar to a pump.

Viper and Cathar already covered the based on actual air flow on a PA120.1, but I'm curious how that changes if at all when you have more dense finned radiators.

Anyhow, this is just more of a quick test to see if I could do it and compare my results to a manufacturers results.

So with that I acquired a more sensetive manometer -20 to 20 inches of water at a .01" resolution to add to my manometer collection

Then I built as small little box to seal a fan on, cut and tapped a 1/4" barb in the side and painted the interior with a coating of silicone for a good seal.

And here it is...
My test setup:


and a little interior shot of the rough box. I wasn't sure it was even going to work so I didn't spend too much time on it.



My results:

Fan: Panaflo FBA12G12M
Static Pressure: .18-.20" H2O (Specs .18" H2O)
Power consumption: 12.03V x .28V = 3.37 watts (Specs 3.36 watts)

Panaflos fan specification brochure:
http://www.panasonic.com/industrial/...s/i/fba12g.pdf

That's pretty darn close!

When I get my anemometer I might add a hole to the back to create a port tube to measure and adjust air flow rate and see if I can plot a full fan curve.

Any wagers what a yate loon's D12SL12 or D12SM12's static pressure is?

Nice. I would love to see a comparison of "industrial" fans (Panaflo, Yate Loon) vs PC fans (Thermaltake, Silenx). See which are truer to specs.

Now you need another chamber with an variable orifice (probably a plate with several orifices) between them and a manometer on both. Then it would be possible to measure flow and pressure, to get the whole PQ curve.

However, I sure you are doing that already

P.S.
You took all the stuff you didn't test yourself out of the spreadsheet!

Yeah, although I'm finding my manometer still really isn't quite sensetive enough, having trouble with the low speed fans.

Thanks for the yate site, I didn't even know they had one. This is what they had for our yates we use daily, nothing on pressure though.

And yes I took all the stuff I didn't test out. Even though I really intended for the tool to be used as educational, people were using it to compare products and I didn't think it was fair to compare two products that were tested on different test beds. After hearing that issue repeated over and over again, I have to agree. While I do everything I can to make my own testing as accurate as possible, I have no way of knowing what others have done. Only way to control that issue is to make sure that I've tested it.

Eventually I'll get those lost parts put back in if the manufacturers are interested in doing so...

Hey, that works to, I did something similar, I was always just trying to feel the air coming into the radiator on the other side of the radiator. Those Panaflos are nasty on the finger bites though..

Yeah they bite......That shot its pulling through the rad, the crazy thing is if there is much of a difference you can feel it pretty easy..I was checking Sunon 108's in that pic..Someone linked me to that fan review that showed the 108 Sunon from Petra sucked, I didn't believe that at all so I checked it...Well they do, they are a 3.2W-108 and I just thought they had done a power saving upgrade or something to them since all the other spec's were the same.. I have some of the 3.2W but I never put them on a rad, just had them blowing on my mobo or whatever..They aren't much more powerful then a 86cfm Pana when you put them on a rad...I have the old 6.8W-108 Sunon on my rad and they pull as well as the 115 Pana...I cant find any of the old 108's anywhere either, they might of quit making them, I hate that, they were good fans for cheap..

This is a 3.2W..


This is the 6.8W...
