Ventilation Fan...Suggestions Needed

Sounds like a plan.

You can hook the fans up to a single adapter. You only need two adapters if you want to adjust or control each fan individually.

FishDad2.....keep us posted when you get the parts and how you wire them all together. I am going to be ordering components shortly and I'll be curious to hear your reviews on those parts.....

yeah, okay. A fan rated at 45 dba is quieter than a fan rated at 28 dba. I get it ;)

All I can say is the stealths are silent on my system.

Couldn't find where someone switched in that thread you posted. I'm not saying there aren't other quiet fans out there, and I'm not even saying there aren't fans that are quieter than the stealths. All I'm saying is the stealths are silent on my system (and they are rated quiet), and I don't have any heat issues. Others on this forum use stealths as well with nice results....

You started off by offering up a 45 dba fan and a $40 adapter. I just thought there were other, better options to consider than that (and I still do ;)). YMMV.

What you arent getting is that the panaflo doenst have to be a 45 dBA fan. With a controller on the fan set to 6v, the fan turns dead silent. If you were to limit its speed to the same as the Vantec, it still pushes more air and with more pressure at the same noise rating. Its not the maximum amounts that Im comparing, its the cfm/dBA ratio, and with a simple speed control like the voltage switch built in to the adapter, the panaflos give the best results.
 
Oh, I get it. That's why I purchased a variable adapter with mine, just in case it was too noisy at 12V. Your initial claim of dead silent wasn't qualified and so it appeared you meant dead silent at any output, which was misleading.
 
piscivorous, will do.

I'll likely order this week...hope to install next weekend...hopefully.

And I may turn back to the thread contributors at that time for wiring advice...I'll see if I can't figure it out myself first though.


crumbletop, that's cool to know needing only one adapter...I may return to you for wiring guidance when the time comes.

I'll need to know too, maybe post work/diagram :0
 
Can I buy three of the Panaflo 120 x 38mm Ultra High speed Fan and just one of the Syntech: PST-1200MF, AC/DC Adapter, Universal 1200mA from Fry's Electronic and be able to hook all three fans to this one adapter?

My plan is to hook all 3 fans to this adapter and reduce the voltage to 9 or 6 to slow down the fans and thus decrease the noise level. I am very sensitive to noise.
 
Well, make sure that the mA ratings of the fans dont exceed the 1200mA that the adapter is rated at or the adapter will burn up.
 
As per the .pdf from the manufacturer, looks like they're 510 mA.

The link hahnmeister posted earlier:
http://www.panasonic.com/industrial.../pdf/fba12g.pdf

Given the 1200 mA rating of the adapter, you can do a maximum of 2 of this model Panaflo. But if you look at the first page of the .pdf, you'll see there are other models with lower operating voltages, so if you really need to squeeze 3 fans onto a single adapter, it can be done...just not with this model.

That is correct. The stealths are 0.08 amps each, so you could run a whole slew of those.
 
120mm...those are like 4.75 inches right? So two should be good enough in a 48" canopy.....right?? That is my thought anyway. From what I gather on here, it sounds like the thing to do is have one on each end of my canopy...both blowing IN with a vent in the top or near the top in the back center to let the hot air out....right??

Anyways. The panaflos are 80mA each.

Did you mean panaflo? On the link you provided, none of the fans look like they are 80 mA. The stealths are 80 mA...


piscivorous, yes air blowing in is good. I have an open back on my canopy and have my fans installed to blow in one of the sides. Hot air blows out the back.
 
Yeah, yeah... sorry, typo. I meant vantec. Yeah, the lowest panaflo os 180mA.

The main reason I prefer blowing in is that it prevents the humidity and salt from destroying the fans as fast.
 
Funny thing is that it's my inbound fan that died first...the one blowing the hot, moist air out is still running fine.
 
What is the best way to mount a fan in the canopy?

--------------------------------------------------------------------------------

I am planning to mount a few fans (probably 2) to the back of the canopy of a 48" length, 18" width, 24" height tank (90 gallon)

The tank will use two Reef Optix 3 with 250 watts HQI hooked up to IceCap ballasts.

I think there are 3 ways to mount the fans.

1. Position the fans in the back of the canopy and blow air to the front of the canopy.
(this way would draw fresh cool air in from the back of the canopy and blow air to the front but the air would somewhat be trapped inside the canopy)

2. Position the fans in the front of the canopy and blow air to the back of the canopy.
(this way would not receive any fresh cool air but it would allow air to escape toward the back of the canopy)

3. Position one fan in the back of the canopy and one fan in the front of the canopy.
(this way would combine method 1 & 2)

I don't know which is the best way to do it. Do I need more than 2 fans? Which way would cause the least evaporation to the tank?
 
FishDad2....that sounds about typical.....there always has to be an exception to the general rule ;) As for the 48" canopy I will be building shortly....I will be running two 175 watt MH bulbs and two VHO Actinics. I plan to have a 12" tall canopy giving me about 8" off of the surface for the MH bulbs. I had considered two fans on each end if I was going with a 3" fan...but that seems like it might be a bit overkill and really more work than I wanted to get into as well. A pair of those panaflows being about 4.75 I would hope would be good enough....???......
