Today's question:
I am looking to buy a new air compressor for woodworking only and wonder what size I need. -Dave Carpenter
This is definitely a question that doesn't have a "one size fits all" answer. Bottom line, you need to size your compressor based upon your needs. Here's the quick and dirty answers:
-If you only use brad nailers, staplers, or have an occasional need to air up a tire then a small one or two gallon air compressor will fit your needs.
-If you plan on using compressed air for everything listed above plus a gravity fed HVLP spray gun I'd recommend something around the size of a 5hp 20 gallon unit.
-If you plan on using compressed air for everything listed above plus high air volume tools like multiple impact guns, air sanders, or to clean out a shop space I'd recommend a larger unit around the 50-60 gallon range.
Beyond that, the most accurate way to determine what size air compressor is perfect for you is to do the following:
1- Find out the CFM (cubic feet of air per minute) usage of each tool you plan on using.
2- Add up the CFM numbers of all the tools you think would be in use at the same time. If you know that only one tool will be used at a time just use the highest CFM number you found. If you plan on getting another air powered tool in the future make sure you know it's approximate CFM requirements and take that into consideration as well. Then add 25% or so to allow future-proofing and other possible long term changes.
3- Find an air compressor that meets your CFM requirements and verify that the max PSI (pounds of pressure per square inch) on the air compressor meets the requirements of your tools.
Things to consider before you purchase:
-Would a horizontal or vertical unit fit my space better?
-Do I need something portable with wheels or will it be a stationary item?
-Is noise going to be an issue? The majority of oil-less air compressors are really loud.

What is the quiet compressor that Shawn uses now? Thanks

A 4 gallon twin tank compressor works fantastic for me. Nailgun, tires, hvlp.
These are great! Please continue filming these! And don't forget the outtakes! :)
Jay, I love the "bloopers " at the end of the video. It takes me forever to get a video (not RUclips videos, just shop updates for my kids) right; I'm constantly messing up or start laughing.
I'm on my 3rd or 4th one now. Finally got a Dewalt verticle 20 gal compressor. Love it. Not exactly quiet but not super noisy.
For my needs, I think the spraying is something I do a little of, and using a hand grinder or impact for the car or metal work requires a bit more capacity.
Tools I bought that get little to no use, Mortiser and Scroll saw. I intend to use them more, just haven't yet.
Tool I didn't think I would use as much, Jet vs1221 lathe. This is fun and there's so much you can do with a lathe.
Thanks for the info Jay and Shawn! 👍👍
The bloomer at the end way amazing. Love this series!
I needed a smaller air compressor recently and got the 4 gallon double stack Hitachi for $159 at a box store (EC99S). Its oiled and reasonably quiet, strong enough to pump up real truck tires decently, handy size and shape to sit in a small shop, and while its heavy enough you probably wouldn't want to move it everyday, you can take it to a jobsite if you need to.
Thanks guys ,you got a laugh out of me with "David Hasselhoff"
Everyone looking for small quiet compressor, have a look at California Air Tools
yes I have one, sooo quiet
also look at Harbor Freight Fortress.
Yous guys is a lot of funns great Job, and Many Tanks
Famous last words for a tool junkie. "Don't buy anything that you'll think you will use...." But I NEED everything!! Ha. Good post, thanks guys.
I was wondering how long before Shawn lost it with David Hasselhoff! ha ha. Good tips.
Love the funny clips guys. Also very useful info. When I started, (Jay knows, not too long ago for me), I had to go for the cheap deal at my big box store. I got the PC, 2 nl guns, staple gun w/ the 6g pancake compressor for $199. WAY too loud cheap compressor, but for the rest of the set, it was worth it for me. I use for the family bike rides and the car. But again, way too loud. Will be looking for a quieter one like Stoney has. (If he can tell me which one he has).
PS. psst Stoney, Jay's gott my email Thx to both of you for what you're doing for us. Appreciate it.
60 gallon, 5 HP 18.1 cfm at 90 psi but it’s for metal working ie: grinders, Air-arc, Sanders, plasma, impacts, etc etc.
Get a rolair air compressor they are the best
I have a 30 gallon husky air compressor and I love it I use it for woodworking and fluid filming my truck
I dispise oiless air compressors they are loud, recovery time is slow. Benefits less maintence, I had a old cambell hausfield oiless think it was about 20 gallon, served me well for everything I did, air tires, run impacts good medium use compressor. But I went to working on mowers and setpped up the compressor to a 29 gallon belt driven model from harbor freight. It was alot better ran my impacts better, I also used it to run brad gun, and having the bigger tank let me run my air tools longer before it kicked on, I also adjusted it to kick on about 90psi and kick off about 140psi this also gave me a longer time before it kicked back on. One thing I also discovered the hard way is in cold weather below freezing to turn my compressor off. In cold weather it had hard time kicking on and would trip my breaker.
When looking for an air compressor, you have to look at the tools you want to use with it first. The tools will give you the CFM (cubic feet per minute) they need to run. DA sanders (which I use) go through a ton of air, like 12 CFM, and sand a lot faster than electric ones. In my shop I use an 80 gallon, 5 hp that makes 16.5 CFM. CFM is the most important factor when determining which air compressor to purchase.
Correct. I made sure to mention this in my pinned comment as well as the website article.
There's also a mentality of "buy once, cry once". A big compressor can do everything a smaller compressor can do, but the opposite is not true. I would argue that if you "might" need a bigger compressor, go ahead and get the bigger compressor.
It's not so much the size of the tank or PSI rating that's important on a compressor, but the CFM (Cubic Feet per Minute) rating. It's the volume of air it can continually move at a given PSI. The low CFM rating on your compressor was the reason you couldn't use it for HVLP. The short answer for this questions is: The compressor you choose needs to match the requirements of the specific tools you want to run.
...and I guess I should have read all the comments first. I basically just repeated what Andrew Tucker already said below. But for those looking for a quiet compressor, California Air Tools are definitely worth looking at. I love mine.
I use a 3 gallon. I can do everything with it almost.
You two are nuts.
I really like these little talks, but it would be much more helpful if you could show us a picture of the item you are talking about.. Visual always goes so much further than words.
what brand is the small quit air compresses?
Eagle EA-2000
What is Shawn's specific air compressor? I'd love to have a quiet one.

California Air Tools also makes some nice quiet compressors.
I know you don't want to do commercial endorsements, but the quiet AC Shawn has, is that from California Air Tools? Been thinking of getting rid of my Porter Cable for the same reason. Sounds like a Cessna is idling in my shop.
what is the brand of compressor you now have?
Eagle EA-2000
You guys kept referring to the tiny silent 1 gallon compressor but never said what it was or gave a model number. WHAT IS IT?? :)
Eagle EA-2000
Thank you sir! You videos are AMAZING. Thank you very much for everything you do.
The Knight Rider 2000, of course!
Hasselhoff, sing us a song!
hahahaha
It's a shame you two don't have any fun doing these...
(couldn't even type that with a straight face. ;-)
hahahaha
I'm looking to buy a air compressor, for nail guns, and die grinders?
I'll keep my Binford 8888 Custom Compressor that is autographed by Tim "the Toolman" Taylor... ;) lol
hahhaa
