Are all air compressors created equally?

Ready to dive in. Any thoughts?

What are you using it for?

I mean, obviously not. I only know a few things about portable ones. Oiled compressors are quieter and longer lasting. Oiless ones are louder and have shorter life without a rebuild.
My makita oiled compressor pretty much stays stationary due to its weight. My bostitch oiless that kinda needs a rebuild goes places. 80lb vs 30lb

What are your cfm requirements? how portable do you want it to be?
Simple answer: like almost everything else in the world air compressors are not fungible.

No, they are pretty much the quintessential tool for "what you pay for is what you get". I have a Makita 5.2-gallon, portable and 1-gallon C.A.T. compressor. There's a reason why a 60-gallon Quincy or I-R cost close to $2k while a Husky at Home Depot will go for less than half that cost. Aside from how much air you need you need to look at duty cycle, recovery rate, oil crossover, 1-stage or 2-stage, voltage, etc. If all you need to do is run a nailer or inflate some tires than a portable compressor will work fine. If you plan to run sanders, paint sprayers, plasma cutter, etc...then you need something else.

About half the compressors sold are worthless due to their size, the only reason to buy most of those medium size compressors is if you are a carpenter or a roofer. Most air tools either require very little or a ton of air. So you need to figure out what you actually want. Large air compressors were needed a lot more 10+ years ago, but now you have electric options for many things that are often just as good. Like impact wrenches for example.

I have a Quincy 60 gallon compressor. I run a plasma cutter and a few other tools that require more than basic CFM. I recently built the pipe fence around my property and needed something more mobile so I bought the compressor below. I've probably got about 100 hours on it now if I were guessing. It is ultra quiet and produces a good amount of CFM for a mobile unit. It pushed the plasma without any issues. Ran it off a generator while I was building the pipe fence around my property and I used it for 11 hours straight this last weekend painting a metal fence with an HVLP gun (not the pipe fence).
It entirely depends on what you're going to use it for, but I haven't found a purpose that this doesn't serve and it's had 0 problems so far. And like I said, it is ultra quiet. It was running next to me and my helper for the day and we could have a conversation without yelling at each other. If you're wanting to run a pneumatic impact or other air tools, this is a good size for medium to light use of air tools.

Industry/commercial is replacing air more and more because compressed air is EXPENSIVE. The proliferation of brushless motors in power tools have made it possible and they also can have smaller form factors more like the air tools they are replacing along with the power users need. A good example of this is orbital sanders from companies like SurfPerp, Mirka, and Festool. The Mirka and SurfPrep have on/off switches on the top just like air sanders.
Surfprep has a more extensive line past just ROS:

No. I also have a 60 gallon 2 stage Quincy. Mine is from the early 70s and will probably out last me. I also have a late 2000s craftsman 25 gallon single stage. The smaller craftsman is great for filling up tires, low cfm air tools or if you are not in a rush higher cfm air tools. The Quincy is the Tits for auto body paint, high cfm air tools, and working on shite with low cfm air tools for a long time before it had to kick on. It also fills the tank in about the same time as the craftsman, but recovers quicker, and can maintain higher cfm at higher pressures while the pump is running to recover. The Quincy pump is also rated for 100% continuous duty, the craftsman is not. They are both pretty close in the noise dept.
I’ve had everything from an oil less harbor freight all the way to the Quincy and the best advice I have is they all have their place and use case. The biggest thing is to figure out what tools you are going to use and get one that can meet the tools needed pressure at its required cfm. And if you want to hear yourself think anywhere near it, try to go with a belt drive oil filled unit or one of the newer quiet oil less ones.

Avoid direct drive oiless compressors.
I'd go with a belt driven unit with oiled cast iron pump. They last longer and you can change out parts if ever needed. Direct drive units are disposable. Once the pump or motor goes, good luck fixing it.
You can get a 30 gallon in 110v and use it in garage or bring it into the house for projects as necessary. If portability isn't important to you, get one as big as you can afford with as big as a pump on it you can find. Again, belt driven pump on the big units. These will typically be 220v, you won't have a shortage for air.

I’ve got a cheap small husky and it’s one of the handiest things I own.
Wife’s got a flat 10 miles from the house? Fill the compressor, throw it in the truck and go plug a tire.
Same with a flat on the side by side in the middle of the woods.
Great for the random low tires in the winter.
Blow up toys for the kid? Slap a blow hard on that thing and air it up.
Great for blowing the mower off after I’m done mowing.
It’s a must have at my house.

ALso, Quincy is made in America, in Alabama.
All those cheap ones the pumps are made in china more than likely, and IR's pumps come from India. I'm not sure where Champion comes from.

I know some are going back to air tools, especially heavy equipment mechanics and metal fabrication. The convenience and cost at first blush didn't always translate, mechanics would waste time with an electric impact that wasn't doing the job before switching to an air tool. I notice that my Milwaukee 12V ratchet does not like extensions, would just rattle but not remove a hard to reach fastener. My cheap IR air ratchet had no issues even though definitely not as torquey. I picked up a Milwaukee 12V die grinder to use it for resurfacing some old cast iron pans I have as well as just for quick light grinding tasks and it actually kinda sucks for the cast iron work. Pisses me off since it wasn't cheap and now I'm looking for an air tool.

I know for my projects around car restoration, I will alway have air tools. My IR 231 1/2 drive works every time I need it to while my brushless Milwaukee struggles with stuck on fasteners. It also adds multiple uses like running a small sand/bead blasting cabinet. So many uses for it. I like the brushless tools also but sometimes you need more grunt. My Quincy is always ready to go.

I work with this pneumatic tool... and absolutely the frick not is the answer.
