    Eaton Compressor/Polar Air 10HP 80ga 2-stage single phase compressor

    So I received this badboy Friday.






    The good:
    • Incredible value for the money - 38 CFM, only $2500 shipped to my door, and runs on single phase
    • Includes the "Whisper" silencer box, which houses the two intake filters and loose sound damping material


    The bad:
    • Comes with a few compromises being a "lower end" 10HP compressor (most are $3500+ and 3-phase), namely:
      • The belts are very short and thus the motor capacitor box touches the compressor at one point, and the belts are already at tension.
      • Thus there is no adjustability for belt tension and the belts must be rolled on/off. (would have been better if the belts were about 2-3" longer to separate the motor/compressor touching point)












    Disassembled in the garage (had to, to transport it to the backyard)








    I'm hoping to have it all working very soon.

    Lot of CFM for the money. Looks like there is room for the motor to move away if the belts were longer. That would bother me, no reason for it.

    Yes absolutely. I'm going to send those pictures to Eaton to see if they can send me longer belts.

    They probably put those short belts on because they know that new belts stretch and wanted to give maximum adjustability.

    Sure they will stretch some but they could have done better with the fit. What I see looks like a mistake, even 1" more on the circumference of the belts would have probably worked.

    I like that silencer box. I will have to steal that idea.

    Yea, it does look pretty nifty. I'm not sure what kind of material they are using, but I could easily see using some acoustic polyfill that they use in speaker cabinets that they sell like at Parts Express. It can be pulled and thinned out easily to perform the same function. It should keep the actual filters pretty clean as dust would not easily find a way all the way up 1.5ish feet from the bottom of the box to the filters.

    We had bought a Eaton 15 hp several years ago. Replaced 1 under warranty second one shook it’s self apart. The cheap import compressor pumps just wouldn’t hold up. Hopefully you have better luck then we did

    It looks like the filter material we use on our makeup air. It comes in a four foot wide roll. Just happen to have a box.

    Eaton's warranty is awesome. Call Todd, he will send you some longer belts.

    Congrats on the new compressor, it's looking good. Even my new IR with the flashy red, white and blue "assembled in the USA" decal has "Made in China" cast into it's compressor pump. Seems to be getting hard to avoid these days.

    No need to, Megan the piston compressor sales rep that handled my order got my email and already has two larger belts on their way to me.

    Just consider the pump as a maintenance Item. Those pumps are really dirt cheap $$ compared any old school quality USA build pump..Like one of these you would never wear out..

    Re: Eaton Compressor/Polar Air 10HP 80ga 2-stage single phase compressor

    What makes Eaton a good compressor is the warranty, they have a 5 year bumper to bumper warranty. They don't pass the buck when the motor, mag starter or pressure switch goes out and has no more factory warranty, they warranty every part of the compressor for 5 years. At this point I would buy another Eaton / Polar Air compressor.

    For those of you that use/used Eaton compressors, did you use their recommended Airbase oil, or some other oil?

    Thats a nice looking compressor. I am looking at their 5HP 60 gallon unit.

    Will you do a CFM test when you get the compressor back together? If so can you post it? I'm looking at that same compressor. Be interested in the full fill CFM, cut in/cut out CFM and amperage draw when the compressor shuts off. Thanks

    Maybe. Only problem is I don't have a CFM measurement apparatus. Please send it to me completely pre-paid. Thanks

    Just measure the fill time from 0psi to cut out. You know the tank size already so with a little math you can have an average CFM.
    Yeah, I know, I wouldn't do it either!

    I supposed that could be a crude approximation that leaves out temperature and pressure-dependent airflow.

    Re: Eaton Compressor/Polar Air 10HP 80ga 2-stage single phase compressor

    Wish I had a CFM apparatus, the problem would be getting all the right adapters. Some of my compressors have 1/2 inch copper lines and others have a 3/4 copper line, some have compression fittings and others have JIC/AN fittings. One has a metal hose with pipe threads on each end with a union. I just use the hokey pokey formula I got from the internet, It works good enough to compare my compressors to each other and to see if a new compressor's performance matches the performance specs. Putting the formula on a Excel spreadsheet makes it easy to compare the performance, I do have a nice digital pressure gauge so my pressures are close and consistent. I always re-sheave all my compressors after I know the amperage draw when the compressor shuts off, I bump up the rpm just a little for more CFM if the motor has a 1.15 or 1.25 serv. factor, I always leave a little reserve though and not max out the motor.

    So the two longer belts that were sent, one looks like it had already been stretched and was longer than the other, LOL. Oh well. Ordered two from Amazon brand new. Almost there, finally! Just need some final odds-and-ends to wrap it up by tomorrow.

    Re: Eaton Compressor/Polar Air 10HP 80ga 2-stage single phase compressor

    Now I'm wondering if I lost a part. This T has one inlet/outlet unrouted anywhere. It joins the tops of the cylinder heads together (I think). Anyone know if this is supposed to go anywhere? I didn't take a pic of this part when I got it, LOL. Everything else is already routed or already capped. Yea I know, I need to call Eaton Compressor in the morning, just thought I'd ask.
