Mate it with a used air compressor pump?

A quick C-note on Craigslist, from someone looking for a replacement motor?
15 amps at 220v and you think it's "6 hp" ?
Try for qty (3) hp.
should drive a nice suction fan/blower.

Milland has the right idea- make an air compressor out of it.

I had to stretch the ol' imagination for that idea...
It's possible the motor is 6HP (like 20A max), but the compressor itself is rated for 15A given the expected load on the motor.
It's "possible" it's a marketing ploy/salesmanship, please search the archives.
Real 5hp motor in link, note current draw:
5 HP 208-230 Volt AC 1740 RPM Motor Leeson C184K17DB31A | AC Motors Base Mount | AC Single Phase Motors | Electrical | www.surpluscenter.com
It's still a useful motor, just don't load it more than about 3 hp.

Look at data tag on motor, it most likely says 6.5hp SPL, the SPL is either indicating its special, or Somebody is Probably Lying....

I think I heard something about it being 'peak' horsepower, either during start or top-of-stroke, or something similarly stupid.
It's 3HP.
It's 3HP.

If it's in a big sticker on the side of the tank, it is absolutely wrong. My wife has a vacuum cleaner that says "4hp"... And it pulls about 4A at 115v.
Marketing people do everything they can, to overstate and inflate performance ratings, and when they can't do that, they just downright lie.
If this motor came off a machine with that kind of marking, my gut tells me it isn't likely to be a very good motor, but if the motor has it's own ID plate, it might actually be a bona-fide 2hp... 220v x 15A = 3.3kw, which is 4.4 ELECTRICAL horsepower. I'm betting they rated it at 15A to keep it advertised within the 'surge rating' of a common 240v/15A receptacle.
If it is a belt-driving motor, I'd find either a good used, or inexpensive import compressor head, and slap it on, and call it a compressor again. I'd take a spray-can or scraper to the 6hp label, so that the new compressor head lasts longer. If you really DO want that kind of power, you need to put a THRUSH sticker, and mebbie a HOLLEY sticker on it. ;-)
