Panasonic Whisperline work with Speedster or similar?

[Guest]

Hey all,

I am new here, just posted my introductory thread. I'm building an NGB style box with cooltubes and a scrubber, and wanted to ask if anyone had experience using a speed controller with a Panasonic Whisperline fan.

I'm pretty sure a standard router speed controller would work, and the speedster comes highly recommended here, so I wanted to ask if anyone could confirm this combo before I make the decision. The speedster says it works for any brushed motor, which is what I would expect drives the fan, but I do not know for certain.

Thanks much!

I use two whisper fans they have sealed motors no brushes.I tried a speed controller it worked but it made the fan buzz real bad. If your fan is sized right you shouldn't need to slow it down.

Thanks for the feedback, I may need to investigate other options, then. For my little cab, I think the fan I am getting is overkill and will take up more space than it's worth.

Appreciate it,

get the 50cfm version. no need for speed controller, and very doubtful you hear it unless youre right on top of it.

I have the 80CFM version rated for 0.3 sones. A 120mm DC fan at 80CFM makes noticeably more noise! How many cubic feet are you trying to cool? What is your lighting setup? What are your room temperatures?

Anything 110CFM and above uses a different type of motor. Some 80 and below models are available with DC motors. I would imagine the DC models could possibly be speed controlled w/o the added buzz. They actually make a deluxe DC model that has adjustable cfm from 80 down to like 30 in steps of 10.

My box is little, NGB style, 3'x2' footprint a little under 3' high. That makes approx 18cf, for 5 exchange/min we want 90+ cfm.

I am going to be running a 250 HPS in a cooltube, powered by a digital ballast. Want a carbon scrubber in the box. I'm building the scrubber a bit big, one of the DurbanPoison styles that is 6" outside, 4" inside, and about a foot long in the filter. This will add static pressure (hopefully less with the large area of it), so I definitely want to do more than 90cfm on the fan. Shooting somewhere between 100-150 seems like a safe bet to me, is this about right?

I've been attracted to the S&Ps due to good reviews and their compact size compared to whisperlines. I noticed something interesting with these from the extended catalog specs (http://www.hvacquick.com/catalog_fi...alog.pdf?PHPSESSID=rt9o19hg94nvtljm4grs4i1ha2).

The 5" duct version (125) is the same diameter of the 4" duct version (100x) in the body and is a little under 2" shorter. It also bumps the cfm (high/low) from 135/100 to 197/149. And from http://www.hvacquick.com/spfnconfig.php?fm=td , this costs 10 bucks more than the bigger 4" one, saves me two inches, and gives me a bit more bang. In my cab I could probably run it on low and do great, I THINK, but this is my first cab, so any input or experience appreciated.

I'd also like to note, my design pulls thru the scrubber and pushes in a straight line thru the cooltube and outside the other side of the box, so heat on the ABS blades shouldn't be an issue.

Thanks so much to those reading and replying!

PS: The subject has now shifted from my thread title, should I make a new thread with this question? I'll let it stay unless someone says otherwise or nobody says anything

Looks like you understand all the math involved and know what needs to be done...so, now your just trying to get people to comment on a fan setup they've personally used? I tried doing that as well and I couldn't conclude much. Some people say their speedsters work without adding buzz and their ventilation is silent (yeah right.) There where a small handful of people who said the speedster did not work for them, and I think they where 10 times as creditable than those in favor of fan control.

I've seen many of positive reviews of the S&P fans. If I had to make any recommendation I would go with one of them!
