Thanks again for all the replies to my original post about my compressor

not working.<br><br>
With all this going on, I have been doing some thinking about having to

compressor appears <br>
to come with a 3hp, 4hp, and 5hp motor.=C2=A0 I have the 5hp.=C2=A0 I

1. What is the advantage of the different hp motors.=C2=A0 I know the big
advantage<br>
for the 5hp is it runs on 220V.=C2=A0 But how does the hp affect the
