Thanks for enlightening me about CFM not being a function of only HP.

I was wondering, how come my HF pancake, which really is 2 HP,
delivers so much less air than my Curtis Toledo, which is only 3 HP.

Well, You really need to be on your toes. At a local place called Fleet
Farm, they have two belt drive models available that are very similar
looking. One is a 2HP the other a 3HP.

Of course, to Joe Blow, they might think that one has a "horse more"
than the other, but it isn't so.

One is MODEL 2HP, the other is MODEL 3HP. They both have exactly the
same motor, same amp draw, same pulleys and Pump. The model 3HP only
has a slightly larger tank and costs almost $100 more. near $100 for a
larger tank..........

The sales kid I hassled about it was sure that there was something
"inside" that made one a full horse power more... Go figure.

I have one of the noisiest peices of junk on the market too, as I
became too cheap to spend the $50 more dollars for the belt drive. Boy
am I Dumb !

Remember too, If your CFM is not adequate for the tool, a larger tank
doesn't necessarily mean much but for a few seconds anyhow.
