    Larry, I think you'll be plenty happy with that compressor. Quincy was my first choice, but since there was no 'local' supplier, I opted for an Industrial IR model.

    Question for you...

    You said in your first post that it was a 3hp 3ph unit. But then you ask if anyone has a line on a 5hp motor. Did Quincy say to up the motor to 5hp...or are you just looking to upgrade it? I'm just wondering what your larger 5hp motor will do with the pump that was originally designed for 3hp.

    Just wondering...

    marty i did call quincy and they told me that if uped to a 5 hp and ran the pressor at 700 rpm it would do around 18 to 20cfm i could have 3 phaze but the cost for it is considerble higher. its 40 a month just to have it then the kw price is higher than single phaze as well.. so a years worth of 3 phaze would be higher than the motor change.

    So, if the compressor has a 12" pulley on it, Steve's 3450 rpm motor with a 2½" pulley would run it at 718 rpm. Compressors that big usually have a pretty big pulley on them, so it might just work out.
