Need advice for fan hook up

[impwiz]

Hello all,

I'm in the early stages of my first grow, and everything is going smooth. My question is, I recently bought a squirrel cage fan from ebay, and it arrived with two female type plugs. I was wondering if I could just splice an extension cord and connect some wires together, or do i need some sort of diodes or resistors to be safe?? I will be using 120v outlet. I am currently using a psu and 4 120mm fans, but my temps shoot up when I close the door on my 2x2x5 box.

Specs of the fan are as follows:
115v
60 HZ
.55 amps
impedance protected
2930 rpm

Any help would be appreciated, searched everywhere to no avail. Thanks

Yeah, I'm pretty sure that would work… but I'm no expert.

Im no expert, and there seems to be a lacking of experts on these boards regarding fans and ventilation, but I think that one you have over 2000 cfm (from memory sry) is way overkill for your box. I was told I should get a 250 CFM for my 4x4x8. Was also told 450. Kinda confused myself.

 

[dknob]

lol my bad I read that wrong.

Thanks for the replys. This fan will be used to exhaust heat from my 400w mh, and exhaust the box also. I'm not sure as to the cfm rating. It's only overkill if i'm sucking leaves out of the exhaust.
I also plan on getting a speed controller for the fan too. Thanks again, I think i'll let this thread mature before I go expermenting. Thanks fellas!

yes, splicing on a cord like that will work. a lot of people do that. it's not the safest, so just be careful and keep it away from water. after you put it together with wire nuts, you can wrap it with electrical tape.

i bought an extension cord and wired it to my fan, it is plenty safe if you use proper wire nuts and some blacktape

thanks guys. I will try to solder it and heat shrink it.

WAIT!! lets see some pics of the whole unit please. The female plugs are on there because they were plugged into a computer or something. You might need a power source like a charger plug or something. If you just hard wire it you might fry something.

it looks like he was quoting what it says on the motor of the fan.

Yea i saw that just wanted to see it. It looks like its only .55 amps that's a small fan. I would double check before i plugged that bad boy in.

It is a small fan, and it was used in medical equipment to cycle oxygen or something. But here is the pictures of the entire unit per SparkaFire's (ironic name???) request.
I haven't spliced anything yet. Thanks for your input everyone.

 

[lorenzo08]

looks pretty nice. wonder how loud it is

Yea buddy In my opinion you DONT want to plug that into a 120 outlet..... You need to find an old charger and look at the amps on the label and match as close as possible. There is a place that i go to that has surplus charger and fans so you might try a electronic surplus store.

Thats my 2 cents

no, don't worry, this isn't a low voltage motor. it's the same type of motor that is often used in freezers and microwaves. this one is just bigger and nicer. without a doubt, it is line voltage, no transformer needed. unless you're in a country with 220 outlets of course..

Sparkafire, do you mean getting like a ac adapter? I'm not sure what type of charger you mean. Could you give a link to a similar product? I will do the nitty-gritty searching. Thanks.

So heres my two cents...

that fan being meant to run on 120v has the two wires that 120v usually uses, the black and the white, but I am going to guess it is rather old,and is lacking a Ground wire.

Theoretically you could splice a normal 16-18 guage extention cord and just simply hook it right to the wall.

But to be honest, because i dont see a Ground wire, I wouldnt use it.

ground wire is completely optional in this case. one can be added, just ground to one of the mounting bolts. these types of motors are pretty safe from shorting, as long as they aren't wet.

My house is so old, it doesn't even have grounded sockets anyways. I am grounding my power strip that plugs into my ballast and psu on a copper water pipe though. I'll do the same for this fan maybe. I will def. not be getting the fan wet. Thanks for all the help. I am going to try to plug this badboy in, i'll give a follow-up.
