Need help wiring a blower for my flowhood
    #17456002 - 12/27/12 03:06 PM (11 years, 1 month ago)

I have a general understanding of electronics & electricity, but I've never been one to do much electrical work or wiring on my own.  That said, I'm pretty sure wiring this thing up should be simple enough that I can safely do it myself.  This is the blower I have, and I will be using it on this 24 x 18 x 5.8" micron filter.

Here is a picture of the wiring diagram from the unit:


Sorry for the poor quality, but all I have is my camera phone and it has a horrible zoom.

So, there are five wires coming from the unit, and they match the colors that are listed on the diagram in the picture (above).  What I'm not quite clear on is, is this diagram telling me to wire the blue & black wires together, and then wire that to the black (or red) that will come from the power cord?

So... that particular connection would have those three wires all being connected via a wire nut?

And then white from the cord will be connected via wire nut to the white on the unit?

And then the orange and red wires on the unit are connected to each other via a wire nut as well?  This one is the part that I'm most confused about.

And why does it say that this blower has two different amperages at 115V?  Does this thing have, like, a high setting and a lower setting or something?

Thanks for your help guys.

4.8/2.5 amps @115V
the motor has a Service Factor (SF) of 4.8amps meaning that for brief periods it can put out more power and it will pull the higher amperage listed by SFA.

when you start an electric motor the motor uses more amp to kick over but will run contuniously at lower amps I.E. 2.5

The service factor - SF - is a measure of periodically overload capacity at which a motor can operate without overload or damage

hope this helps.. as far as your wiring diagram i have no clue.

Ok, thanks for the info.  I did not know that.

What about wiring it up, did I read the diagram right?  I.e., black AND blue from the blower to black (or red) on the cord, white on the blower to white on the cord, and red and orange on the blower wired together with a wire nut?  If that's the case, I'm curious to know why red and orange go together like that?

I have no clue as to why those two are connected together. Possibly for a different diagram for some different power uses those ... ie European or 220 volts or something. Wire it up exactly as it says. It may also be for different speeds or direction, but obviously they don't want you to f with it so do it as it says. The capacitor is either a start cap or most probably a run cap - saves power.

The white wire should go to the neutral side of your plug. The neutral will be the wider of the two prongs on a polarized plug ( which you should be using ), the white wire of a 3 wire cord, or the wire on the cord that has a rib or ribs on it. That will make sure your hookup is properly polarized.

Yes,  wire it just as you have described. Black and blue together with the black from the cord, white to the white of the cord, and orange to red together.
Depending on the blower you may need a capacitor, if it was new it should have come with it, if not new look for a part number and type that into Google and start reading, pdf files are great for that kind of information.

Ok, I wired it up and it is working fine.  Now I am curious to know if there is some way to regulate the speed on this particular blower?  Might that be what the orange & red wires are for--to put some sort of speed regulator in there?  And what's with the blue AND black wires on the fan going to the hot wire on the cord?  Thanks guys.

Why would you want a speed Control unit ? With out the proper gauges you cant tell if your SP is high enough.. you should have a tek to building a LFH that gave you specs on what CFM  you need for the size of filter your using... some blowers are ok to use with speed controlls some arent.. you would have to research weither or not your blower is ok to add SC too.. some speed controll units claim there good to use on any blower but blowers are much more expensive than SC so id go with what my blower said.

If you want to adjust speed, simply adjust the supply voltage with a potentiometer.

The equivalent blower from grainger contract supply is 309$
not to suggest you cant get cheaper.... just sayin

Wiring in a simple rheostat into an alternating current/motor applications not only will not work but could also put the OP's life at risk. Please do not post anything you know nothing about, your bad advice could kill the OP or someone else. Music power is not the same thing. An electric motor using alternating currents' speed is adjusted by frequency not by voltage. It requires much more circuitry than a simple rheostat. Please edit or remove that post. We do not need anyone following that bad advice.

OP - DO NOT try anything like that. Purchase a UL approved 'motor speed control' and even then it may not work with that particular motor.

Jeezus H Chrizt, if you don't know an answer, don't pull total bullshit out of your ass and post it here.  There is not one word of the above that is accurate.

Same answer the other guy got.  You don't adjust speed of an AC motor with a pot or other current limiting device.  You guys have got to stop posting bad info around here.  It's no dishonor to simply ignore a question you're not qualified to answer, but don't just make shit up please!

To the OP, find a different blower.  That one is over 1000 cfm @ .8" w.g. so it's a bit too much.  Also, disregard on the FP site where it gives two different currents for 115 volt operation.  That's because they're not electricians and don't understand electricity any more than half the posters here.  Besides, you can get that made in china blower for half the price elsewhere.

Didnt make this up its how it was explained to me on the production floor.. not saying its right.. but i have assumed our maintenance crew knew what the hell they were talking about cinsidering they are professionals that work with this shit all the time. it was explained to me as peak and normal usage of electricity.

sorry if this is miss information, but as far as i know everyone learns most of what they know about shit from other people, this dosent mean were "pulling shit out of our asses".

NEVER EVER do that with a/c power.

A variac is designed to vary the voltage of an ac power circuit. You may be able to use a variac but I would consult the blower motor manufacturer and ask them how to vary the speed.

Thanks for the input everyone.  I wired up the blower the way the wiring guide tells me to, and it works fine.  Given all of the complicated (mis)information that I'm getting regarding speed control, I'm going to go ahead and assume that's a lost cause -- and hey, fuck it, I'll settle for whatever I can get at this point.  I purchased two other blowers before this one, both of which would not work and are not returnable :|  I'm just happy to have something that will work, for better or worse.

I'm at my wits end trying to find & purchase blowers here.  If this one will be "a bit too much" then it's just going to have to be that.  What are the consequences going to be for me if I use a blower that is a bit too much?  I don't know so I'm genuinely curious.

Every single aspect of my own personal growing methods have a bit of ghettoness to them, so I guess the overly-powerful blower on LFH will have to join the club.

Just wanted to say , using a over powered fan will increase air flow and cause a lot of turbulence .
There for not achieving laminar flow.

Since you already have the blower, simply stack up a few prefilters to help reduce flow.  Get it so a Bic lighter flame bends over 60 degrees to 80 degrees, but doesn't flicker or blow out.

I've looked at FP may times and I still am amazed by the fact that they cannot give shipping prices over the internet.  It takes an email.

I've sold lots of things over the net and if you know the size and weight of an item, you can determine it's shipping cost.  So that is total BS.
