I've never owned a large air compressor before

That’s a good point 2black1a but I’m not sure they make such a 30 gal anymore. I’ve only ever seen less expensive ones. I’m assuming the motor you have is 220V to have that much capability and I don’t know that I’’ve seen a 30gal like that. Then again, when looking at 220V, I shift to 60/80-gal because those are most prevalent.

Yes it is 220V. And like you, I haven't seen any 30G compressor's with the performance of this one either.

It's manufactured by DeVilbiss and was marketed and sold by Sears under their Craftsman brand. They don't have anything close these days.

I remember raving about its performance to my dad and brothers when I got it and they also went out and bought one. So there are three of these compressors in my family today.

Hypothetically, could two 30-gallon compressor/tanks be connected in parallel? (Assuming unlimited cash, space, and power...). Would that have the effect similar to 60 gallons that fills quickly?

Yes you can combine two compressors. Putting them in parallel increases CFM, in series increases PSI. You’ll need a tee to combine them but also put an air check valve for compressors on each line so that one compressor isn’t able to pressurize the other compressor’s tank. And make sure each compressor is on a separate power circuit or you’ll likely trip the breaker each time the second one turns on since the initial power on load is greater than its running load. And if you use an extension cord, make sure it is beefy and rated for the greater initial power on amperage of your compressor based on the length of extension cord.
