I wouldn't be too quick to write this off as homeowner grade. For the past few weeks I've been researching a Mac compressor with a bad motor that I got from a friend. Actually spent way too much time researching, so got to know the specs and differences between a lot of different models.
First thing I noticed when looking at the pic is the size of the motor. That ain't no little 56Y framed 5 HP or 6 HP motor that a Costco model would have. That's a 215T framed, 100 lb plus motor, pushing at least 7 HP....so now we're moving up to big boy territory. Looking at the pump, and keeping the size the the motor in mind, lead me to believe it's more than likely a dual stage with a CFM rating in mid 20's or higher. More big boy goodness. And underneath all that manly muscle is an 80 gallon tank. When you add it all up you've got something that's got big power, can pump on the upstroke and down stroke, and has the size to last all night long without breathing hard. This is something hot chicks drop their ******* over....but don't buy it for that reason only.
Did a quick search on google images, came up with the compressor linked below. I believe it's the exact model. Snap On price is $5k. Probably $3k-$4k from the company that makes it and puts their label on it. The Mac branded compressor I have was made by Bel Air, I didn't research this any further but that would be a good starting point if you wanted to figure it out.
