What Size Air Compressor Do You Really Need?

The quality of the air tool also makes a difference. My 30 gallon 5cfm @ 90psi can barely run the $10 cut off tool but the $60 cutoff tool runs great. Not all air tools are created equal.

I have an 80 gallon Ingersoll Rand for blowing out tractors and tires. I also have a 20 gallon Sanborn I use to air up tires so I can get them rolling to the shop to be worked on. The most used compressor is a 2 gallon Fortress turned down to blow sawdust and use as an electric shop duster.

[@jameshill4900]

It's also very important to use high flow fittings and larger diameter hoses (3/8 min. - 1/2 best) for anything that requires higher cfm. Make sure your regulator has a cfm output that matches or exceeds your compressor. For low cfm or dyi odd job users I would advise nothing smaller than a 2 cfm compressor. Quite usable for most tasks. Anything smaller is almost painful.

[@Fireship1]

Milton V. They are high flow and make a huge difference along with large diameter air hose.

[@jameshill4900]

@@Fireship1 The V is a good very high cfm fitting. It's nice because it uses the standard 1/4" intake (which I assume most people here would be using). I've had great luck with them. The larger fittings I use are reserved for my tools that have the 1/2" intake.

Impact wrenches are used in short bursts and then a break before running again. A large tank can help with that. Smaller compressors work fine if you manage your usage.

[@SvdSinner]

You only need the full power of the impact wrench to break the nuts free. As long as your tank is large enough to run it hard for a second or two, you can get 90%+ of the functionality from a basic compressor that you can get from a giant compressor.

[@donaldroehrig7817]

Yes, our engineers did the math and we ended up going with a 75hp variable speed screw drive compressor and two 100 gal tanks. Also, our main air lines that run the length of the building are 3" hard lines, and these act as storage as well. We have air to spare, but with the variable speed drives, we don't waste power. People forget to factor in the electrical cost to run a large air system. It can cost thousands of dollars a year depending on demand.

[@TexasScout]

Re: Impact gun I have never had to run an impact of any size continuously. I have a 20 gallon comp that puts out 5.7 at 90 PSI, I have never been short of air while rotating tires or changing blades on the mower. In fact, many years ago I ran a small sand blaster continuously with a Sears 5 hp hot dog style comp. Made a living painting.

[@DavidStrchld]

I have a Craftsman compressor from like 30 years ago, has specs like yours, in using the impact gun I really have not had any issues of note, after all it's only run for a short time normally, with a good resting time inbetween, however if I did have a really tight lug nut I may have to get it to run to it's cut off point (125 PSI) to get enough of a initial breakaway, though that is rare. I think it has to do more with the losses in the long hose length and 3/8 diameter hose then anything else. The air ratchet uses more air, but it works fine with it.

Yeah, if it doesn't break the lug loose immediately when pulling the trigger, try the following: a) bump up the pressure b) get a better large ID hose c) get high flow air couplers d) get a better impact gun

[@josephszijarto1170]

Love your tool reviews Bear, but there's some inaccuracy in this vid unfortunately that's misleading people - you'll notice a lot of people now opting for electric tools below. A tool's SCFM rating at a certain PSI can be satisfied by a compressor with a far lower SCFM provided you have an adequately sized tank for how long you need to run the tool. If you want to run it constantly, for a very long duration, then the compressor does need to keep up directly with the volume of air the tool requires as you mention. An impact wrench will run perfectly on a 20 gallon compressor at 90-120psi for any reasonable need. It will run at full performance until the pressure drops below the rated value. The biggest power-robber you'll find are thin hoses and quick-disconnect couplings (air restrictions preventing you from getting the needed CFM from the tank). You'll have to wait a minute for the compressor to refill to remove that next wheel if you want 'full power', but not a problem for most home mechanics as tire rotations aren't exactly professional pit stops. For very air-intensive tools like drills, grinders, even perhaps HVLP, you're correct you do want something big enough to directly satisfy the tool's air needs. On the pressure part too, you mention you'll 'never use' 135-150psi. You're correct, you'll never use that at the tool, but that's the pressure in the tank. The greater the pressure given the size of the tank, the more air is in it. And the more CFM you'll get to the tool before the compressor kicks on again. You can't talk about tool SCFM requirements without talking about tank size and the maximum working pressure in the tank - it's not all about the CFM the compressor can constantly output.

[@respond_code3]

So what CFM rating can i get away with for a impact wrench? I found some 8-10 gallon compressors around $140. I dont care if i need to wait for it to kick on to do the next tire.

[@wingerrrrrrrrr]

@@respond_code3 it just depends on your patience level. Even a puny sub cfm compressor could be used to fill up a big storage tank to a sufficient operating pressure, and could run the impact wrench enough to remove all the lugs on one wheel. Then take a coffee break before doing the next one. To me 2.3 CFM at 90 is enough to not try my patience much. The key is making sure your wrench and fittings allow enough air delivery and torque to impact the lugs off immediately. If you're sitting there impacting impotently, it'll use up all the air in a jiffy, and then you'll have to sit and wait before trying again. That's where it's an exercise in frustration.

[@respond_code3]

@@wingerrrrrrrrr thanks. I ended up finally getting a compressor. Looks like Home depot had one with the wrong price on it. Was shopping online and saw they had a WEN 20gal for $187.

[@wingerrrrrrrrr]

@@respond_code3 what's the CFM rating on it? I actually prefer higher CFM with smaller tanks over bigger tanks because that allows it to come up to operating pressure quicker and still allow continuous operation. The tanks are supposed to be drained out after use, so a big tank means a longer wait if the CFM isn't upsized accordingly.

You can run a really strong 1/2" air impact wrench (capable of 1000lb-ft) on a 20 gallon, 4SCFM tank - I've been doing it for 25 years. If you're doing heavy suspension work, there's still no beating air. You just have to pause every minute or so to let the compressor refill the tank. Bigger tank, less pauses. Bigger compressor, less pauses. Plus the air tools are much cheaper than electric typically, and you never run out of battery. The Bear's understanding of how pressure, tanks, and tool SCFM requirements work isn't too good unfortunately.

you can even run a Graco sprayer that uses dewalt batteries. Expensive but man do professional painters love it and it works like magic

[@edwarddavis507]

Just a thought. If you’re running electric with a cord, yeah you should hang onto those because they will always work and will last decades. If you are running cordless than you might find you are spending more money on replacement batteries so the air tools have the advantage. I think it’s all dependent on the user.

[@markmall7142]

To complicate matters further one should be aware that the rated CFM or l/m is not actual and you should rather spec on FAD which pertains the delived CFM if the info is available. Another thing to consider is noise especially in a home shop so DB rating could be significant and having a smaller tank could be beneficial as it fills quicker equating to less noise for shorter periods and less power consumption .

[@David-hm9ic]

Since most of us that are hobbyists would use impact wrenches and all of the other air tools intermittently we don't need the compressor to deliver the big CFM on demand all the time. I have worked in an environment where we used air tools all day every day so I know the difference. A bigger tank can keep the tool going for a while even when the psi/cfm rating falls short. Those ratings are for using the tools nonstop all day long. Unless someone is making a living with their air tools and every minute matters, it's OK to wait on the compressor once in a while. I have a 25 gallon Craftsman with a BS power rating of 4 HP. It's over 25 years old and I have rarely had to wait on it. It's due for replacement because I'm allergic to air tank explosions. My tools include an air drill, paint guns, a die grinder, random orbital sander, 3/8" air ratchet, little to big nailers and a small HF sandblasting cabinet. That's the real air consumption device. Someone I know is a city civil engineer. When the city built a new fire station he was told that the fire department needed a 230V 3 phase air compressor to inflate the tires on the fire trucks. "Nothing but the best for the fire department." He had to abide by the recommendation ($$$ Thousands for an air compressor) when a $600 115V 1ph compressor would have been more than adequate.

[@DKWalser]

Red -- I know Jeff helped with the research on this one, so, while you're technically correct in the stats, he reached the wrong conclusion on a few things. First, the SCFM requirements from an air tool can be met -- briefly -- with the air in the compressor's tank. Second, a higher pressure compressor puts 'more air' in its tank -- allowing it to run an air tool for longer than a lower pressure compressor with the same sized tank. For example, I have the HF 27 gallon Fortress High Performance air compressor. It runs up to 200 PSI and produces 5.1 SCFM at 90 PSI. That 27 gallon tank effectively equals a 54 gallon tank at 100 PSI. It will run an impact wrench for several minutes (not continuously, but as you normally would use the tool -- several short bursts at a time). Plenty of air for removing or putting on all the tires on a car or truck, for example. That makes using virtually all the typical air tools practical for the home shop -- with the exception of large sanders, buffers, and grinders. (They make small (3") random orbital sanders that only consume 3 - 5 SCFM, so you can do SOME sanding. But, a 3" sander is a specialty tool. You'd want something larger for most work, and those sanders will outpace my HF compressor.)

[@matthewcantrell417]

Another great video I have really been enjoying your content, I work in Industrial maintenance and wanted to share another decision point that most people don't think of when deciding on weather to go compressed air vs electric/battery powered tools. It is the cost of running the tool (electricity). Anytime you use compressed air to do the same job of something that can be done with straight electricity you are using 7 to 10 times more electricity (money) to complete that work. Even most Companies that have huge compressors don't realize how much money can be waisted for the convenience of grabbing an air hose and plugging in that air tool. Where I work compressed air is the last resort option, we would prefer to spend a little more upfront on the battery/electric option and recoup the savings over the long term use. I hope people find this comment helpful, and I look forward to more videos.

[@jameshill4900]

Interesting. Is that a calculation you figured out or found somewhere? What parameters is it based on (continuous use or intermittent). On intermittent use 7 x cost vs air in the long run sounds high. Batteries do degrade and weaken over time. Air tools do not and are always putting out 100% * as long as there is air. (PS I do use battery powered tools but also use air for my larger tools).

[@MrSupernova111]

Yeah, but the real comparison is a long term comparison and my bet is that the air equipment will last much longer than battery powered tools. I think they're both great but let's be fair in the comparison.

I had a 5th wheel RV with Goodyear 16 tires, they took 105 PSI. Large pickup tires can be 60 to 80 and I have been told that some people run the Goodyear tires above on their pickups. Way over 80 PSI. Using the impact wrench you will find the longer you can keep the pressure at 90 or above the performance you will get. The sanders, grinders and sand blasters are the worst. The issue is not only the amount of air you need, but the length of time you need to use it. Draining a 20 gal. Compressor in a 2 or 3 minutes and then waiting for it to completely refill.

I have a lot of experience with my Central Pneumatic 21 gallon now (same line as the 29 gallon I believe), and I have to say it's done me well. When I started to notice real limitations was with an air sander, like he said something spinning at high rates like 12000RPM for a long time if going to just eat your air. I wonder how it would do on a 60 gallon, my guess is that would be sufficient based on my experience. I could drain the tank pretty easily in a couple minutes, and it takes a long time to fill back up so wasn't a great solution. On the other hand the HF HVLP gun worked great, I got great consistent spray and it took a while for the compressor to start turning on. It would also turn back off so air compressors still can work well for a variety of tools, but you definitely should consider cordless tools when it makes sense. Look at pin nailers and brad nailers though, you never want to buy a cordless unless you're a professional, they're literally like $200. I got a brad nailer and pin nailer that both work fine from Harbor Freight for around $50. I will say the pin nailer won't do 2" pins like the Dewalt one, but then again the bigger ones also won't do 1/2" typically. There is a lot of great resources out there now to help with choosing between air and cordless tools. I will say my Milwaukee cordless drill set i.e. was one of my favorites, but not everything is so mass produced and air tools can still work great sometimes for cheap. Look at Milwaukee's best impact wrench something like $500, yeah it's super powerful but still not as powerful as an 80 gallon air compressor with a quality air impact wrench. Buy five of those nicer cordless tools that actually compete with the 80 gallon tools, and all of a sudden you're already around $3000 after taxes...

All my switchs are mounted out side the room and I have a large line leaving the tank to outside the room with a extra very large tank to hold more air.

Check out the 2 gallon Fortress ultra quiet one from HF for 140 on sale. Super unobtrusive if you have the compressor in the same room you're working, and decent output for light use.

[@jimquinty5378]

do you remember when harbor freight had US General compressors? I think I might own one of the last from 10 years ago for a 60 gallon tank that that is 2 stage (175 psi) that puts out 15.3 cfm at a 100 psi and its been outside under a shed dormer (porch) and still runs with very little maintenance

[@pkt1213]

Since I put up over 500 ft of privacy fence, I didn't use mine a lot. Most of what used to be air powered for me is now battery. I guess the real problem, most of the tools with lower air requirements have been replaced with good battery tools. Now what I need air for still requires a beefy compressor like a sander, so it really hasn't resolved my compressor woes.

[@zackhaas3267]

The Central Pneumatic 29 gallon will run any impact full power up to 3/4" with the right setup. The biggest thing with it is to change out the factory regulator to a decent regulator. The factory one is EXTREMELY restrictive.

[@anthonywilliams2764]

Ok I need a compressor to fire out sand and cement mortar to exterior walls for rendering!! What sort of compressor will I be looking at ? Taking into account it will be used continuously for 2-3 hours per day ??? Yea lease help

[@txrangers717]

I have a porter cable 4 gallon side stack compressor that my father dropped off at my house a while ago (he used to work in construction). I've been thinking about fixing it up to working condition. It's missing the regulator and he told me the safety valve leaked so it wouldn't reach cut-out pressure. The interesting thing about it is the scfm it produces for a small compressor. 7.7 at 40 psi and 5.3 at 90 psi. That seems to be higher than any other compressor I can find at that size of a tank. What would be the recommended uses for that? It seems to be borderline impact wrench territory, but it seems like the 4 gallon tank would run out of air quickly.

[@Fireship1]

I’ve got four. A bellaire two stage 60 gallon, Sears two stage 25 gallon, HF single stage 8 gallon and Sears single stage 3 gallon. I use the best one for the job at hand. The 60 is my favorite of course. ☺️

Was looking for a beginner's guide to air compressors. But...holy sheeeeet....that animated bear! I gave up on the vid half ways through. 🤭

[@TheMadWookiee]

Bear I can tell you I ra n a CH 27 gallon 110 volt compressor for 20 + years. I ran blowguns tire fill chucks impact guns HVLP paint sprayers diegriners a sand blast cabinet and a plasma cutter. Ware I ran in to problems was my high demand air tools the tank pressure quickly drops to a unusable level. Also prolonged use brought a second problem Moisture! As in water would come out the tool. And yes I should have quit long before that point and yes I drained the tank often. My plasma cutter is the worst the manual states we recommend a 60 gallon tank minimum if I used the plasma to much and got moisture in the air line it would ruin the consumables that got expensive quick. I did my research I bought a Quincy 60 gal 220v v4 two stage compressor it is quite for a big compressor and all my tools run better on the 60 gallon compressor. It’s great to run a tool long enough to kick the compressor in keep going and have the compressor top the tank !

[@scarling9367]

I've found that a 20 gallon compressor will do fine with impacts for the DIYer. Bust a wheel down...do you what you need to do and move on to the next. Pit crew tire rotation...definite not. Meanwhile, a DeWalt cordless impact w/ 4.0ah battery can give a full rotation in one go. Take that all for what it's worth in your decision making process.

[@cb84capri]

Also the power usage of the compressor running, noise, dragging air lines around a vehicle etc

[@scarling9367]

@@cb84capri In the 20 gallon range, almost all those compressors still run off 120 volts.

For a home shop two cheapo HF compressors hooked in tandem will give you the CFM you need and do it cheaper than a large professional quality compressor.

[@matthewnicholas6365]

Soooo, is the reason my 1/2" impact gun struggling to get my wheel nuts off because my 50l 2.5hp compressor "only" has 9.6cfm? It makes a lot of noise but sometimes makes zero "impact"

[@loganowley876]

I am an owner of a roofing company. at times we have tried to have 3 guys running 3 roofing nailers from the same pancake compressor due to lack of power supplies when it comes to roofing at manufactured homes. Occasionally we will use generators but fewer compressors is better. we can have 5 to 6 guys roofing on the same roof. So im looking for a compressor that can handle minimum of 3 workers. So any tips would be awesome. thank you for the information in this video.

[@BrewCityRider]

Interesting how many of the bigger HF compressors actually have a lower or equal CFM rating to the 8 gallon 2hp one, which is 4.5cfm and in my garage. Works great with my 1/2" impact - just make sure to use 3/8" I. D. hose and V or H style fittings.

[@benjaminabel8596]

I'm starting to think that bigger tanks are a scam. PSI is PSI and once it goes down, it doesn't matter how much air is in the tank, just how much PSI the tank can handle and the force of the motor.

[@bowez9]

Lol should compare to the Cooper Turbos we use at work 400hp 3Phase 480v idle at 190amp, load at 490Amp and startup of 1200Amp. These only put out a max of 120PSI. OH the motor weights 2.5 ton and costs $30k to rebuild.

[@frijoli9579]

One thing not addressed is the actual way they measure compressors. They are not measured by compressor output. If you have an air tool that runs at 4cfm and 90 PSI, a compressor rated a 4 cfm at 90 PSI will NOT keep up.

[@Poorboychickencoop]

The bigger the tank is better for weekend warrior mechanics. I've bought these styles alot.. I'm now building my own which equals the $3k compressors. 27 cfm 7.5hp motor single phase 230v. The problem with battery tools is they wear out fast..

[@trolling4dollars816]

Good video coming from someone that has stated more than once that air powered tools are dead ;) One fact that was left out is that the maximum PSI is not as important as the PSI that turns the compressor on. I had to buy a 175 psi max compressor to supply a constant 125psi to my steel piercing nail gun. See you Sunday

[@Smashachu]

You can build a 12cfm aircompressor for 200-300 if you can compromise on tank size.

[@HiroProtagonistak]

I help out at my buddies auto shop he runs ingersoll rand compressors and they rarely get used. When they do it's not to their capability. Cordless tools are the way to go. If they could make a cordless auto paint gun it would be great.

I want to pump, bicycle, tires, hundred psi and 125 psi, so what size compressor would I need for road bike tires?

SO...I have a question about all this, hopefully you'll get back to me sooner that later. I need to spray my backyard fence with Austrian lumber oil stain. I have about 1,000 foot of fence that I need to treat. I haven't purchased my spray gun yet and nor do I have a compressor. What would you recommend for this type of job? Thanks for reaching out! Any insight you might have is going to be greatly appreciated.

[@tdiddi74]

Need a compressor for car/motorcycle tire inflation and blowing water off after wash. Thinking about the 1 or 2 gallon Fortress compressors. Which one would is recommended? Thanks!

[@joselozano0528]

Both the Pittsburgh 20 & 12 ton air/ hydraulic bottle jacks require 120 psi.

[@JohnDoe-ig1yw]

Very informative video. Thank you. Definitely not buying 2000$ compressor anytime soon for home garage. I will have to find a different way to break free this axle bearing on my Sienna from bearing carrier now that I can not use my air hammer.

[@Sylvan_dB]

What size do you need? Bigger. About the only time I wish I had a smaller air compressor is when I contemplate moving mine. (5hp real - 30amps at 240v, 60 gallon, continuous duty) I regularly wish I had a bigger compressor.

[@michaelmusson3593]

you are not going to be able to run that Quincy in a most residential area it's three phase usually will require an electrician to drop an extra hot.

[@terryburke2587]

I have a Puma 20 gallon compressor that is rated at 5 CFM@90 PSI and it will run most air tools fine. It easily runs my Ingersoll Rand high end impact wrench. Impact wrenches take a lot of volume but only for a short period of time. A big tank can provide a high CFM for a short period of time even if the compressor is rated low. The only thing I can't run would be sprayers and sustained grinder use. Don't buy the oil free versions as they are noisy and wear out quicker. Get a two cylinder fully oiled unit.

[@GrabberBlue71]

my little DeWalt pancake compressor has been more than enough for my household needs. I'd recommend that to anyone

[@JB-by8zk]

Hello, I just need for small sandblaster for Harborfreight? 60 or 80 gallon??

[@siucbset]

Idea: I would like to see where you were to take a normal impact wrench and you would have a real world working condition and place it with a 6gal, 20gal and 30gal compressor. Basically you would be showing how long an impact wrench would be working in a long term real world application. eg. How long will this impact wrench bang on this crank shaft bolt for each compressor.

[@losmoore3358]

Does air tank size or gallons matter and why ? I see smaller tanks take same PSI as the bigger air tanks.
