thoughts on a blower?

$15 + shipping for me

650 CFM, 1.5" H20

what do you think, for a fedco 2-342

obviously would not run at 48v, too noisy.

thinking 12-30v.

I would be going from an 80 CFM Torin to this.

better buy an ear muff to go with it

Looks like a hefty blower... Noisy too at full voltage. Not sure I'd count on an industrial blower like that to be any quieter even at lower voltages. Many tend to produce a horrible vibrating/whining/or humming noise when undervolted.

However, for 15 bucks, it may just be worth the try.

What are you lanning to use it for? Blowing through the rad I assume? I hope it's not in your PC.

:/

said I'd run it signifigantly slower.

vonkaar has the same blower, says it is quite quiet.

blowing through the rad, it will sit on top of the PC and blow down.

the blower will be quiet, guys... that is not a worry...I am more interested in the relative meaning of the 1.5" of h2o and P=Q chart.

hmm..... price is good......

voltagewise it appears you're stuck with 36-56V .......

i suspect it'd still be noisy at 36V......

EBM D1G133 blower. ($10 on Ebay) 700CFM 48vdc blower from hell. 700cfm is a lot... enough that you would think that it would be noisy as can be... it's not. If I run it at 40vdc, it's almost silent. It's rated down to 30v... I may 'pot' it to control noise. However, even at 48v it's quieter than most of the 120mm axial fans I've used.

see, guys? quiet.

pauldenton, frequently specs are not the actual case. My torin is only supposed to run at 12-27v, but at 7v it spins up fine.

well pabst say 60dBA at 48V .....

but unless vonkar's one was a freak example i say go for it... :thup:

worst case you either sell it or try to source a different motor.....

(3 answers and a reply from you while i was composing mine..... guess i must type slow...

)

Yeah, I saw that, and it surprised me quite a bit.

We will see when it gets here. I'm hoping for 100CFM actual in relative silence

a pressure drop curve on the 2-342 anywhere by chance?

Joe Camel · Jul 16, 2004

under volting a blower (or over volting)...ive often wondered just how much it effects the "specs"...arnt fan blades in HIGH speed fans (tornado) shaped/designed for their stock speed? are blower cages' blades/fins shaped/pitched to their stock RPM? EDIT: i also wonder if the pressure is effected more than the CFM with lower than stock blower RPM...

anyway...im sure that blower @ 12-30v. will move more air than the Torin @ 7

and i think THAT is the point!

tsulas · Jul 16, 2004

Heh... Give 'Er!

I am sure they are engineered to run at stock, but I don't need 400+ of actual CFM (accounting for heatercore resistance).

I will run at whatever is quiet, but I hope it's not more than 30v....the PSU I built for the torins only goes up to about 28v....would be a shame to have to redesign

sure you do, that means you can stack 2-3 heater core's ontop of each other and still have about 100 cfm coming out the other side

Where are you getting it from? I may go the same way come to think of it.

www.quickar.com, I believe I have the last one, though

judging from the p/q curves of these pabst radial blowers it appears even...

they also sell them on ebay for $10
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=36324&item=3827862077&rd=1&ssPageName=WDVW
it is even the same company that sells them
they are selling one pretty much all the time.

that's funny, they told me they had one left.

klath · Jul 19, 2004

Says 48VDC (36-52VDC) in that ad. I think even 24V might be pushing the lower limit not to mention 12V.

your guess carries as much weight as mine

will know for sure when it gets here
