I am in Iraq Speedaire 1WD78 need wiring instructions...

I am in Iraq at this time and have been given a Speedaire 1WD78 Air Compressor for my Soldiers to run their numatic tools.


The problem we have is there is not an instruction manuel to hook it up to the generator power we have.

We have tried trial and error but do not want to continue it the fear of frying something. It did not come with a cord running into the box so we have to hook up a cord ourseves inside the front box to a 220/240 power source. I just need to know were I need to hook all wires up to make this work. I have looked for a manuel on line but I am not having any luck and really don't want to spend $50 on something that is not mine and will stay with the government when our deployment is over.

Can someone please let me know how to hook the wires inside the box and to the power source.


Thanks,

belt size for Speedaire compressor

What size belt goes on a 10hp speedaire compressor

____________________
Bill says...

Tough question, since there may be many models of 10 HP Speedaire compressors out there.

Visit the Speedaire page, see the info on finding your local dealer, and contact them with the model and serial number. That should do it.

Cheers,

Bill

speedaire 2Z370

by John Repac
(Billings, MT)

I recently purchased a speedaire 2Z370 diaphram compressor from the second hand store. It appears to be in good shape and (I think) functions properly. What are the uses for this compressor? Can I use it with my hvlp gun? Thanks.

Hi John. You've got the cart before the horse, my friend.

First, you decide what air tools you want to use. Then, you look at these tools from the perspective of what air flow they need (CFM) and at what pressure (PSI) they need that air at, and then you find an air compressor that provides, at the minimum, the flow and pressure that the tools need.

I cannot locate the specifications for your air compressor, so I can't tell you what the expectations are for the flow rate and pressure of that compressor.

And, since there are many, many brands of HVLP paint guns, all using different flows and pressures of compressed air, I sure can't tell you if your diaphragm air compressor will run it or not. Sorry.

Cheers,

Bill

Speedaire compressor ? Safe pressure...

by Drew Malbica
(Vancouver, Washington)

I picked up a speedaire Air compressor from a friend of mine and I really don't understand to much about it.

It's model number is 3Z406.

It does not have an on/off switch.

All it has is a plug and and then it starts pumping. It is suppose to shut off at 150 and restart at 125psi. I have yet to pump it up that high because it seems to get hot and start to smell like an oil smell. It needed to be topped off with oil so I did that. Is it safe pump it up to 150 and see if it shuts off then use one of my air tools to see if it kicks back on again? How much pressure can the tank safely hold. Thanks for your time.

Hello Drew. The Speedaire compressor will be engineered to safely have the pressure reach the normal cut out pressure setting. If yours is 150 PSI, then it's OK to let it run up to that level.

Read about the PRV linked from the site map to understand this safety feature on your, and all, compressors.

If you leave it running until the pressure gets to the normal cut out level, and it shuts off, good stuff. Run your air tool, and when the pressure drops to the normal cut in level, the compressor should restart.

As to the smell, can't really comment on whether that's normal or not, as I don't know your compressor. All DIY compressors (and most industrial ones too) run quite hot.

Try it. If it doesn't make 150 PSI and craps out, hope you didn't give your friend too much money for it.

Good luck. Keep us posted as a comment here, K?

Cheers,

Bill

yeah but...
by: Anonymous

Yours may be shutting off at 160 psi like mine is. I don't know if my compressor is supposed to shut off at 150 psi or 160 but 10 lbs is not too bad a discrepency. Tanks are supposed to be rated at a much higher capacity for safty reasons. Mine is a model 3Z406. I tried to find the info about mine but couldn't. Can you tell me where you found the info on yours?

Anyway, what I'm suggesting to you is let it fill just a bit longer to see if your switch is shutting working at 160 psi. Maybe you got lucky like I did and it's operating at that.

I don't know if there is an adjustment on these like on my Craftsman. I can set the dial on my Craftsman to turn off at any presure within a dertain range. I just keep it at around 150. Most of my tools are rated and below that. I have one old floor sander that requires high preasure and high volume so I have cranked my craftsman to shut off at 175. I can also adjust the cut-in on the Craftsman. So I guess I have another question, Do these Speedaire compressors have this kind of adjustment?

I have one too.
by: ARTIZAN

Hi, I just wanted to let you know that I have one of those Speedaire compressors too. I got mine with all the stuff my dad left me and my brother. I already had a Craftsman portable and I know that my brother had left this Speedaire with my dad and when my dad passed, my brouther wasn't interested in this old thing. I had an opportunity to trade it for a small very dirty travel trailer, so I decided to take a closer look at it.

First thing I noticed is that it has a two cyl pump, I liked that right off the bat. I tried plugging it in and it tripped the breakers. It did run and complress then it started straining and tripped the breakers so I tried turning it by hand and it seemed fine but there was a bit of resustance. I noticed the oil filler and decided to add some oil and try it again. It fired right up and pump nice and fast. I watched the guage and it stopped at 160 psi. I am very happy with this compressor and I don't think I will be trading it.

Can anyone tell me how much a compressor like this is worth?

Thanks.

Pressure switch
by: Drew

My speedaire compressor as listed in topic pumps up to 150 but does not shut off it just keeps going to max the gauge at 160 so I unplugged it. How do you tell if the pressure switch is bad or not?

___________________

If it normally shuts off at 150 PSI and now just goes on past that point then you can be pretty sure that the pressure switch is at fault.

speedaire 2z499b wont build any pressure.

by henry
(ethridge, tn)

The motor runs fine but it won't build any pressure. No funny or unusual noises. There is also a fine film of oil around the pump and on the tank. When the pressure release is pulled nothing comes out.

____________________

Henry, make sure you don't have an open line (ie: tank drain) while the compressor is running. Won't be the first time that's happened.

Or, your compressor might have a valve problem, with air sucking in and blowing back out of the intake port. See if you can feel any huffing out of the intake port when it's running.

Failing that, next most likely is a gasket failure inside the pump, with air circulating back and forth inside, and nothing going into the tank.

Cheers,

Bill

Model 2Z499D
by: Anonymous

The compressor I have is a 2Z499D not 2Z499b. On this compressor there is 4 ports. Two 5/8 inch ports in the middle of the Head and one 1/8 inch port on each side of the 5/8 inch ports. As I stated both the 5/8 inch line and 1/8 inch line goes into the tank; however only the 5/8 inch line has a valve. The reason I am asking this quesion I taught I might disconnect the 1/8 inch line, because there is a slow leak with I cannot find by spraying soap water on all the fitting. I taught because there is no check valve on the small line and it may be leak out via the compressor.

Thanks; DavStur

Whoops. Type on the model number. Neither are current with Grainger, unfortunately.

I can't tell you to disconnect the 1/8 line as I am not sure what it does.

I do believe, however, that if you have soaped all the fittings and cannot find a leak, you might want to check the unloader valve to see / feel if air is slowly bleeding out there. If so, then it is the tank check valve that is probably leaking.

Copper Lines
by: Anonymous

I ask about the small 1/8 inch line comming from the cylinder and goes into the tank. Then what is the larger 5/8 inch copper line that has what looks to be a check valve on it and comes out of the cylinder head in the middle of the two cylinders and goes into the tank? The large line is in the middle and the small line is just off to the right of it.They both go into the tank but the larger one has the valve on it.

Thanks; DavStur

Obviously I spoke to soon DavStur. I have tried to locate a photo of your Speedaire compressor model 2z499b with no success, and Grainger doesn't list it anymore either.

Please start a new thread about identifying this line, and please upload photos of it from all sides and we'll see if we can help figure out what it is.

Small Copper Line
by: Anonymous

What is the purpose of the small 1/8 inch copper line comming out from a port in the head and going into tank.
________________
That is how the air gets from the cylinder of the pump down into the air tank as the compressor is running.

2Z499D line gets hot
by: DavStur

I have 2Z499D that has a small 1/8 Copper line comming off the top of head of the compressor going back into the tank. I is getting very HOT is this normal. The main 5/8 line that goes to check valve is equally as Hot. My question is this normal for both to get so Hot?

Thanks: DavStur
______________
It is common for both lines to get hot enough to burn skin, which is why they are typically copper, aluminum or of high heat plastic.

I cannot tell how hot yours are getting since I cannot see or feel them. If you can touch them and not get an instant blister, you are probably OK.

The longer the compressor runs, the hotter these lines will get.

Speedaire 10.3 cfm @90 psi 60 Gals tank

What the maximum head temperature in operation because the copper pipe ha been heated?

_____________________
Bill says...

Howdy Timmins. I have some fond memories of fishing Lake Tatachikapika some years back.

Compressing air generates a lot of heat, which is why the line running from the compressor head to the tank is a metal alloy. Most other materials would melt. You will burn yourself if you touch this line or the compressor head after the compressor has been running a while.

Sorry, but I don't know what you mean by "because the copper pipe ha been heated".

Cheers,

Bill
