Makita MAC2400 2.5 HP* Big Bore™ Air Compressor

I’ve been using the Makita MAC2400 for a few years in my home garage, mainly for automotive work. I regularly ran an Ingersoll Rand impact gun, air grinder, air hammer, and air nozzle off it, and this compressor never let me down. The quiet operation (79 dB) is a huge plus – I could comfortably work in the same small space without feeling drowned out. The Big Bore design really does make a difference: faster recovery time, solid airflow (4.2 CFM @ 90 PSI), and consistent performance. Maintenance is simple – I changed the oil regularly, and the cast-iron build feels like it’s designed for decades of use. It’s heavy, but the roll cage design makes it durable and portable enough for job site or garage work. Overall, this is a professional-grade air compressor that delivers industrial-level performance, value and the reliability Makita is known for. If you need a unit that runs cool, lasts long, and doesn’t blast your ears, this is the one. ✅ Pros: Quiet, powerful, durable, excellent recovery time ⚠️ Cons: Heavy, not the easiest to move around frequently

I am a construction contractor in California with over 34 years experience ... and I am hard on my equipment. I purchased this Makita MAC2400 back in January 2012 for $299 from Amazon and use it almost daily, running wide crown lathing/roofing staplers, framing nailing guns, finish nailing guns. air blowers and most often pneumatic air chiselers/air hammers. This compressor is now working on its 5th year of labor without any issues, with the only maintenance being - oil changes ( which I have only done 1 time so far) and making sure that I drain the air tanks at the of every day. It has enough air power to run 2 nail guns simultaneously and run a pneumatic air chisel ( which draws 4CFMs) all day. While it does recycle almost continuously , when running a 4 CFM air chisel, this Makita MAC2400 has never quit on me. Some might complain about the weight (80lbs) being a con, it is a heavy compressor for its class (twin hotdog) but I believe that the oil lubricated, cast iron pump and steel construction is a pro ....due to the return of its on the job toughness. I also like the fact the this compressor is on the quiet side of noise output, couple that with its low RPM, makes this compressor easy to leave in the same room that you are working in, The low amp draw is also an added benifit and I rarely trip any electrical circuit breakers, albeit, I try to keep the extension cords lengths to a minimum and try to use the highest gage (14g or above ) when ever possible. If, I need more length I use more air hose. I used to kill Oil-Free compressors in the years past, MAC2000, Dewalt, Rigid 45150 .... while they were lighter in weight and powerful, they were very loud and with the teflon lined cylinder pump ....wore out within 2 years of purchase. If you dont mind the weight of this compressor it will do the job for you in the years to come.

This is definitely one of my most favorite items I've purchased from Amazon. Excellent air compressor. Well constructed, good workmanship, quality parts, smooth running, and it even looks great, with a quality paint job. Plus it's much quieter than the "Task Force" 5 gallon compressor that I replaced. And the performance of this Makita puts that 5 gallon "Task Force" compressor to shame. It easily runs every air tool I've hooked up to it...nail gun, staple gun, paint sprayer, etc. Also, in the questions section for this compressor, there have been some nebulous answers as to whether this compressor will run an impact wrench without difficulty. I can assure you that this compressor can run a 1/2 inch impact wrench with no difficulty. This compressor is fairly heavy. As you can see from the pictures I've included, I mounted it to a cart that I purchased from Lowes, so now I never have to lift it again. The cart came with 4 inch polyurethane wheels, but the wheels had no brakes. So I replaced them with a set of 5 inch polyurethane wheels with brakes. (I put the 4 inch wheels on my Rubbermaid mop bucket...much better than the wheels it came with). The compressor would have probably stayed firmly planted on the cart due to the compressor's weight, but I preferred to bolt it to the cart. The compressor has four rubber feet bolted to the frame, so bolting the compressor to a cart is simply a matter of drilling four holes in the proper place on the cart, remove the bolts from the rubber feet on the bottom of the compressor, then set the compressor on the cart, then run bolts through the holes in the cart, through the rubber feet, and then tighten the bolts into the frame of the compressor. The rubber feet that come with the compressor would probably be very good at cushioning any vibration from the compressor to the cart, but as long as I had them off I decided to replace them with a set of very high quality sorbothane anti-vibration pads ($30 for a set of four 2" x 2" pads). I drilled a hole in the middle of each pad then bolted the compressor and pads onto my cart. I put the rubber feet that came with the compressor on the bottom of the large case of my home-made computer. Perfect fit and better than the feet that came on the computer case. As you can see, I also bolted a retractable air hose reel onto my cart with 50 feet of good quality rubber air hose. I also put an air/water separator onto the air hose that does a very nice job of removing water from the line before the air enters whatever air tool I have attached. A push-valve on the separator allows you to drain any drops of water that it might collect with just the push of a finger. One more thing. The compressor comes with one small bottle of compressor oil. The compressor will take the entire contents of that bottle to get the oil level to the full mark on the oil sight glass. I filled the compressor with the included oil and then ran the compressor for the required break-in period specified in the owner's manual. After that break-in period, I immediately changed the oil. I used high quality Royal Purple synthetic compressor oil when I changed the oil, and the compressor runs even quieter with the Royal Purple synthetic then it did with the oil that was included with the compressor. I hope this review is helpful for anyone looking for a very decent air compressor, as well as giving some helpful suggestions for mounting the compressor to a cart.

This compressor oozes quality. Was looking for a “portable” air compressor to keep in the garage for DIY projects, blowing, and airing up the occasional tire and other miscellaneous tasks. Ordered the IR dual tank at first. When I received it, both gauges were bent. Called CS, they shipped two wrong gauges. Called CS again, was told I wasn’t even in their system. Returned that one, didn’t learn, ordered another. That one had a cracked manifold that would spit oil. So I returned it as well. Ordered this compressor. Double boxed for shipping. Unpacked it, installed air filter, filled it with the included oil, plugged it in, opened the drain valve, turned it on, let it run for thirty minutes under a no load condition, turned it off, checked the oil level, closed the drain valve and let it build up pressure to automatic shutoff. Let it set to make sure it wasn’t leaking any air, which it wasn’t and didn’t. Plugged in the air hose, shot brad nails and staples on a playhouse project, aired up every tire. Blew out the garage. Blew off the mowers. Ran a small grinder. No tripped breakers. No leaks. No oil spots. Turns on when it is supposed to. Turns off when it is supposed to. Holds air like it is supposed to. Is it heavy? Yes it is heavy. Is it loud? No. It is more quiet than the little compressor it replaced. It is quiet enough that I can run it in the garage with the doors closed. Impressive build quality and functionality. This is my first Mikita tool, I can tell already, it won’t be my last.

I was in the market for a new compressor and wanted something that would be versatile for most applications, relatively quiet and had a decent reserve tank. I compared all the various models in this class and finally settled on the MAC2400. I'm glad I did. I was a bit hesitant to order it from Amazon versus the big box store, but my unit arrived in perfect condition and I didn't even have to consider a return. As usual, Amazon Prime insured it arrived quickly, saving me the trouble of having to go to the store. First, the unit is really simple to use and maintain...a little bit of oil, flip a switch and away you go. (I've yet to do an oil change, but that doesn't appear too difficult.) It's ready to go after just a short time, so you don't have the long wait that larger compressors do. The MAC2400 is not nearly as loud as most compressors this size, which is nice when you're working within an enclosed space. (My friend's large PC is almost twice as loud!) It's had the power to do everything I need so far - finish nailing, impact wrench drives, stapling, filling up vehicle tires and cleaning things off. This unit probably doesn't have the capacity to run higher demand applications like sanders, paint sprayers and so forth, but I was aware of that and accepted the limitations. While using it heavy and fast, I've noticed it does kick on a fair bit...but that doesn't bother me since it's not too loud and I expected as much with the portable size tank. The size is just about perfect, too...easy to build a rolling cart for, complete with hose storage. About the only thing I don't like, and this is true for virtually all compressors, is when you release the air tank...it's ear-bleeding loud...I don't even like to be in the same room. I've outfitted the unit and all my accessories with quick disconnects, which is practically a necessity. I also hand-selected my accessories as opposed to getting a kit, I think that's a smart way to go. (Most of the accessory kits are cheap and you'll end up replacing them anyway.) Again, Amazon has a great selection here. Overall, I would recommend this compressor so long as you don't require a larger tank or the use of greater CFM tools. (If you do, you shouldn't even be looking at this unit!) But, for the common home compressor, this was a good buy at a great price. I hope to see many years of service from this Makita!

This thing is absolutely outstanding. Well packaged, and no part of it looks or feels cheaply made. It’s super quiet, and has thick rubber feet. I put it on a bench top to do the break-in (they recommend 20 min; I let it run an hour), and it didn’t walk or move on the table at all- so, basically NO major vibrations. I’m using this in my wood-shop to basically blow off things, but I will occasionally use an air impact gun, but not much else. If you needed a little extra capacity, it would be easy to plumb in another tank very cheaply. eventually, I may get a small nail gun, which is what this thing was basically designed for. Anyway, I am super happy with it; could not be more impressed.

I bought this compressor to remodel an old house and I need to run all kinds of air tools from nailers (mostly) to sanders to whatever... It is a source of power on the job-site. Many others here have given great kudos to this fine machine and I am one of them. It is very quiet and powerful. It will not paint your car or run an air sander, but it will run most any other nail gun or other tool you have (rated at 4cfm or less). What I like about this tool is that it gives you two connections on the front panel, so I can run two tools at once. It is heavy! Has a handle for one handed carry and if you are the incredible hulk, you might pull that off. Some say it weighs 80 lbs, but it feels like more, it is a beast! Course, I wouldn't trade the weight for a lighter, poorer made compressor, the weight is just what you have to deal with if you want this nice machine. Amazon is a great retailer, but read the fine print. This compressor has oil in it and because of that, it is NOT RETURNABLE! I had a problem and needed to return mine and hit a brick wall. Finally, after working my way up the food chain at amazon, a very amiable resolution was made. But buyer beware, the fine print says that this compressor is not returnable and they are not kidding. You can pay more at a local store and get local service or take your chances at amazon. I love amazon, but this is not their core market and if you need service, you are going to deal with Makita (not altogether bad). I have a craftsman compressor that has much more horsepower, bigger tank and a higher cfm, but it only serves as a noise maker and can not keep up with the Makita. The craftsman will be in my next garage sale.

I've had this compressor for two years now and it's been a trooper, it's run nail guns, staplers, air chisels, blown off small engine parts, you name it and it's stepped up and did the job. It runs quietly, smoothly, and has never kicked out a breaker. I um "sold" the idea of a new air compressor to she who must be informed of any new major tool purchases by using the return on investment strategy. By blowing out the irrigation system myself I could get a payback in less than three years. (That was my story and I stuck to it ) However, the Mac2400 just didn't have the volume to do that well, it got the job done, but struggled. Also, I began getting more into using an HVLP paint gun and one of those small cheap end of hose sand blasters both of which the Mac2400 struggles with. Nothing big, just some occasional use, painting a wrought iron fence, etc. So, I decided to add a three gallon air tank to it to increase initial capacity. I chose three gallons to stay within the 50% duty factor, the 3 gallon tank is just slightly larger than one of the tanks that exists so it looks right installed and it would all fit on a plywood cart I built and it would cost under $100 total. So, following is the three gallon tank addition and the results. I purchased a Firestone 9127 3 Gallon 2 Port Air Tank also a Viair 90005 Tank Port Fittings Kit and splurged on a Viair 92804 18" Stainless Steel Braided Leader Hose without Check Valve just for looks. Various fittings/bolt etc. brought the total outlay to just under $80. In hindsight I should have purchased the Firestone 9148 3 Gallon 3 Port Air Tank which would have made draining the tank easier but thought I could stand a bit of fiddling for $25. I didn't use one of the many 5 and 11 gallon portable air tanks for two reasons, although cheaper most are rated to only 125 psi and don't have more than one port, so no way to drain without removal, and under rated to the Mac2400's output. The whole assembly process can be found on you tube and that's what I used as a guide. The only thing different was I added a quick connect to the end of the stainless hose so I could run the Mac2400 with or without the additional 3 gallons. Results: Initial fill takes about a minute longer and recovery after the compressor kicks in takes 14 seconds longer. It now handles the irrigation system much better with only one vs two sometimes three cycles per section. I tested my 2.0 nozzle HVLP paint gun at 12 seconds or 12 one second bursts before compressor kick in before the additional tank, and 22 seconds after. That doesn't sound like much but the result is by 22 "bursts" it's usually time to move and the work just flows better as moving or adjusting the project fits the compressor recovery timing better. As far as nailers and such go I don't even use it as the Mac2400 easily handles that kind of work without the additional tank. I'm glad I did it, it expanded the Mc2400's usable work, making some things much easier, didn't cost a lot, and gave me an enjoyable afternoon in the shop. Oh, and that return on investment strategy... that works too.
