......and in reply I say!:
I am not so sure about the extremity of the problem of power claims,

unless the US is now getting even worse than here in OZ (and these
things all come from Asia anyway, right? G).

I have a "2.5HP" direct drive comp, quite cheap, that delivers about
7CFM at 90 PSI. This gels with the 3 CFM/HP claim. So it is _not_
claiming to be a 2.5 HP machine, when actually it's only say 1/2 HP
usable, with a stalled current to make it 2.5.

So I would be careful about assuming that this 3/4 HP motor will
deliver as much as a modern "2HP" motor or whatever.


i have read the thread but want to state here that _any_ two hp motor
needs 220-240vac to run. you cannot get it with 110-120 in _normal_
environments. special wiring/breakers might get you close, but that
would require planning (in which case you would plan 220) or retrofit.
