Another Air Compressor Topic - Manual?

[UncleJerm76]

Just jumped on a old Dayton, single-stage, dual piston, 5hp, 80 gal vert compressor. Looks like things are hooked up a bit wonky & fugly - but everything works.

I've got several questions, so I'm breaking them out into specific threads so they don't get lost or forgotten and so they might help someone else ...if I can find the answers.

This thread is specifically for finding a manual. I've tried all that Google has to offer but I'm coming up for air empty handed (pardon the pun). Actually, nothing what-so-ever is coming up for this model compressor! So... It's a long shot — but does anyone here have this model/manual/or have a suggestion where to find one? I want see what pump & motor is supposed to be on this unit (I currently have my doubts) as well as the recommended maintenance hoopla, plus tool manuals are just cool.

Dayton Model# 5Z589

Dayton is just a brand name used by Grainger. They didn't make the compressor. Post some good pictures of the compressor pump itself and somebody will be able to identify it. Then you can get parts and repair manuals for the pump - the rest of the parts (tank, motor, belts/pulleys, pressure switch, etc) are generic and can be purchased anywhere.

Great advice! ...Here's the pump, I have never seen one like it. Can't find air filters for it (attached a pic of them also-they are a weird L-shape) and it looks to me like the heads could be on on backwards? Can those just be unbolted and flipped around so that the air filter can be taken off without interference of the belt cage?

Wow - I've never seen a pump exactly like that one either! Hopefully somebody on here can provide a proper ID. I know that there are Italian-made pumps and ones imported from Brazil as well, and it might be either.

Do you have any idea of a mfg. date?
The "Manufactured for Dayton Electric Mfg Co" is a give away that it was made by somebody else and just sold by Dayton.
(They made electric motors, so it probably had one of theirs on it.)

I have seen their name on fans and other stuff that the clearly used as a means to sell their motors.

...this is the motor ID and is another reason I suspect it's not original. Which is fine. But id love to know what twin pump I'm dealing with for maintenance & replacement parts. I looked over the pump real good and didn't see any stampings on it. I have not been able to get a good look at the side that's behind the cage yet. I'll spin it around and look for something there.

It does appear to have had a plastic cover of some sort on the front of the compressor case (opposite of drive shaft side - see pic)? You can see there is still a small piece of plastic tab remaining in the bottom right of the case in the photo.

And I have no idea why the drive shaft goes through the case and out this side and what this is broken off of it? So many questions lol

Oh and here is a pic of the oil level window in case it helps for identification. (I've already drained it)

I did take all these pics to a few places that sell compressors (including Grainger) and got a bunch of head scratching. This one is going to be a challenge to figure out.

HUGE thanks to Jim for making a copy of the manual and giving it to me! Now that I have the manual I know that both the compressor and motor have definitely been replaced so the search is still on. Thanks a5t1 for Kens contact info, emailing him now....

So, we have now established that you are in possession of a Frankencompressor!

Recently I did see one pump similar to yours on CL but there was zero information given that would have been helpful in identifying it.

For those of you still following along... I haven't stopped looking, and I finally found the pump model number: 3Z898A

I also came across some very interesting pics on online auctions that tell me what I have is indeed all OEM. The Dayton compressor pic I attached below seems to also be my EXACT components, from the big Leroy Somer Motor to the odd looking aluminum compressor. Has the same compressor fins on the top, even has the plastic case on the outside that mine seems to be missing (explaining what was broken off that shaft going through the motor—a cooling fan!). It appears the cooling fan ran off of the pump shaft and used the plastic cover to channel the air to the fins - odd, but neat! Reminds of the way the air-cooled riding lawnmowers are setup.

Now I'm thinking everything I have is indeed OEM and has not been replaced as I first thought. It's strange because it doesnt match up with the manual I have, maybe my manual is a reprint from a later date, but it definately lists it as being correct for my model compressor.

I'm still no closer to finding air filter replacements or how to order other replacement parts like the missing plastic cover, cooling fan and a rebuild kit for the pump. My motor is missing the cover for the capacitors & wiring also that I'd like to replace. Grainger doesnt sell anything for this model any longer. I'm almost to the point of fabricating up a common air filter, but Id like to use this one if at all possible so Im exhausting all outlets.

The pic also raised a new question, you can see a large box at the bottom of the compressor that all the wires are running too. Is this a magnetic starter for the 5hp motor? If anyone has any insight on that I would appreciate some info. I dont want to burn up my motor or pressure switch by not using one if I need it.

OK, so I did some more web searching, and I strongly suspect that your compressor pump was made by Anest Iwata. With the fan and shroud, it looks very similar to the oil-less pumps sold under the Powerex brand.

Take a look at this oil-less pump on Ebay - what cinches it for me is the air filter castings:

http://www.ebay.com/itm/IWATA-POWER...r-Replacement-Pump-/321723447034#ht_190wt_885

From looking at their website (link below), it appears that this company makes both oil-lubed and oil-free versions (as used by Powerex brand of compressors) of their compressor pumps, and obviously you have the oil-lubed version.

http://www.anest-iwata.co.jp/english/compressor/reshipuro/PLU_kei.html

They also have a web parts site that requires user registration:

http://www.ec-ai.com/en/Login/

I'm not sure how to figure out what the manufacturer's (as opposed to Grainger's) model name/number of the pump is, and even if you can figure this out, there is a very good chance that they no longer make or stock parts for it (this is very common for non-industrial-duty compressor pumps). And even if you do find out that the parts are available, my hunch is that they would cost almost as much as buying a complete replacement pump (say, from Harbor Freight, do other searching on this site regarding that topic).

Getting back to your question above, yes, that is a motor starter shown in the picture. Your compressor size is right on the borderline as to whether a motor starter is required. If the motor itself has internal thermal overload protection (usually there is a red 'reset' button on the end of the motor, but not in all cases - in some cases, the reset can be automatic once the motor cools down), and the pressure switch is rated to switch a 5HP motor, then you can use the pressure switch directly.

But backing up a step, how is your compressor wired up now? Is the motor directly connected to the pressure switch? If so, leave that alone for now. Otherwise, there are dozens of excellent threads on this site already that talk about every possible thing you would want to know about sizing and wiring up motor starters on compressors.

You might get away with running that compressor pump as-is, simply by adding external forced-air cooling to the pump. You could wire two 120V fans in series and then connect them directly in parallel to the motor, so they would turn on and off in concert with the compressor.

Looks like a Powerex compressor, which is either a Campbell Hausfeld brand, or owned by the same company that owns CH, Scott Fetzer.

Looks like a Powerex compressor, which is either a Campbell Hausfeld brand, or owned by the same company that owns CH, Scott Fetzer.

Which, in turn, is owned by Berkshire Hathaway (just looked it up yesterday).

But Powerex is nothing more than a brand name, just like the Dayton name that Grainger uses. I don't know that they make their own compressor pumps.

Another option for the OP getting pump parts is to go to a dealer that carries Powerex, and maybe a good parts person can cross-reference that pump to a Powerex part number and look up parts that way. Here's one company that carries their compressors and parts:

http://www.californiacompressor.com/powerex_air_compressors.html

Here is one Powerex website - this link features twin-cylinder, oil-lubed pumps as used on climate control compressors - this is going to be very similar to the OP's pump:

http://www.powerexcompressors.com/climate-control-compressors.html

It might be worth giving them a call - try to get somebody in the parts or service department that is willing to spend a few minutes on the phone with you to help you identify the exact Powerex model number for your pump (who knows, maybe there is a location that it is stamped or engraved on the casting somewhere).

This website appears to be the official Powerex company site:

Holly cow, Thank you MacMac & Redmond!!! This gives me a lot to go on!

I've got a semi-frankenstein compressor, same motor with an IR pump / tank.
Trying to find manual / wiring diagram on the motor and not having much luck.
(The data plate on mine is faded / illegible)

Did you have any luck ?

No sir, ended up filling the compressor up with oil and just used it as is. Gave up my intentions of fully restoring it. However, recently the motor stopped working so the search is in full swing again.
