    Geez, we almost need "go to meeting" here.

    Okay.

    The fan marked 25a is now on the other end, turned around so the same edge of the fan hub is closest to the armature, and THAT end (the 25b end) is turning CCW?

    That fan will pull towards the armature.

    If the shaft in the pic is turning CW, then the flow will be AWAY from the armature, but I don't understand why the airfoil design faces the wrong direction compared to the airflow over a wing.

    Unless they are doing that to help reduce cavitation....

    I'd have to read something about that fan to really know, but yes, CW in the pic WILL pull from the armature toward the shaft end.

    ART!!!!!!!!!!!!!!!!!!!!

    i know a little i say little about air foils
    so i agree, i think the original fans which you see here are on wrong!

    that being said!!!!!!!!!!!!!!!!!!!!

    did trane put the airfoil on the wrong side????????????

    i'm confused............... if it spins ccw, and the fan is supposed to direct refrigerant into the motor, installation is correct.
    they used vapor to cool the stator? usually they inject liqwid

    I hate making decisions that go against what i pulled out!!!!!!!!!!!!!!!!!!!!!!!

    anyhow that fan is now on the other side spinning CW and hopefully pulling cool liquid out of the evaporator

    but airfoil seems wrong??????????

    From looking at the parts list on page two of the pdf, it looks like one fan goes on the far end for CW, and one goes on the near end for CCW.

    Which way does your shaft turn? CCW as shown in your picture?
