MAC240

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

Today I received the compressor that I ordered. Amazon delivered this morning. Their truck was BIG. Not your typical Amazon truck. Both men were awesome. The box had no damage. I removed the two straps that held this in place. Removed those copper staples and took a look inside. Inside, there was another box with black straps. Lifted that box out, removed those staples, and 3 black straps. Makita factory really, really protects this to the max. Good job, Makita! Took the compressor out and enclosed the manual, oil, and filter. Each item was in its own plastic bag. I put the compressor on a dolly for now. I read the info about adding oil and an air filter. Here is my tip: put the oil in first and use the included oil plug that came in the bag. Next was the air filter, which was easy to install. Another tip: get a crescent wrench to remove the air filter; now you have a stem to tighten. Once tightened, reinstall the air filter and tighten the wing nut. Did a circle jerk around the compressor and saw no damage at all. Not even a scratch, Next, I fired her up and opened the drain valve and let her run for 20 mins. The compressor ran quietly. The only thing that smelled was the paint the whole time, and most likely the pump and motor that were painted. UPDATE 2/2/2026 Before I turned on the compressor, I spotted a small oil leak coming from underneath the crankshaft. I took my hand, placed it beneath, and felt oil on my fingers. I then looked at the Allen key screws on the crankshaft cover and saw that the bottom was not flush with the crankcase housing. I proceeded to tighten (noticing that the screw was easy to tighten as I was doing it). I fired up the compressor, then shut it off. About half an hour later, oil on the bottom of the housing. I thought this was not good. I called Makita customer service, and after a lengthy discussion, it was best to return to Amazon, request a credit, and reorder. So I did the return and reorder. I trust Makita will do right by me. I will update again this weekend, as I will be receiving the new compressor this Friday, and Amazon is picking up the defective one also. Final Update: I received a new one and returned the defective air compressor. The new compressor was packed the same way as the old one. Took the new compressor out of the shipping box and didn't notice any oil at the bottom of the box. The defective one did have an oil stain on the bottom of the box. I checked for any assembly or shipping damage, but didn't find any. Assembled new compressor (oil, air filter), then fired up the compressor and did not have any oil leak at all. Then I shut off the air compressor, but I did not release the air from the air tanks. The gauge showed 140psi cut out. I let her sit for 5 hours and saw the gauge drop to 132 psi. For me, that was an acceptable loss of pressure. This is a great compressor for a homeowner. Thank you, Amazon, and Makita!

Absolutely amazing air compressor. I’ve used an Emglo twin tank air compressor for the past twenty years but when it gave up the ghost, I almost ordered a replacement from Jenny (the new owner of the Emglo brand). Those are twice the price of this Makita. Amazon delivered it the very next day. It was very well packaged and although the packaging is corrugated cardboard, it is a very robust type and is double, triple and even quadrupled layered at the necessary points. Unpacking is a breeze as it final assembly. One must first fill the compressor with oil, (provided in the crate) and spin on the intake air filter. The compressor oil provided is the exact amount needed so pour it all in. Makita has included a witness window to show the oil level, something Emglo has never done. That’s a nice feature. I plugged it in and threw the switch and was astonished by how quiet the machine runs. I don’t own a noise level meter but this is easily only half the decibel level of the Emglo. I let it get to pressure, pulled the pressure override thingy and let it come to pressure again………probably ten times. I then left it plugged in, threw the switch to the off position and then left for five hours. When I returned, neither the tank pressure nor the regulated pressure gauges had dropped even by a pound. Makita has done a great job with this unit. I saw other posters complaining about the weight. This is a heavy duty, robust unit. They may make a little girl’s compressor……….but this one isn’t it. Very, very nice unit.

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.

I did some research on many of the compressors out there and chose to go with this model. I looked at the Dewalt, Rigid, Porter Cable pancake deal, and few other no names. I was tempted with the Porter cable deal with the 3 guns but I don't use anything below 18 gauge and I need guns that can carry 2"+ pins/brads. The porter was loud and felt cheap but it did the job as my buddy has one. On the guns I decided to go with the Grex 650L 23 gauge pinner, (amazing gun) and the Hitachi NT 50AE2 18 gauge. I went with this compressor due to the reviews it had from previous customers. I am a carpenter and will use it for crown, base, wainscot and other trim work. Here are my thoughts after using it: Shipping Experience I ordered from Amazon to take advantage of free shipping option. Unit came in about 5 days via UPS. Shipping Damage The box it's shipped in is not very durable considering it's supporting an 80lb compressor. There was just layered cardboard, no foam, peanuts, or Styrofoam molding. Many of the reviews in 2006 stated that air filter is shipped loose and typically damages the gauges. I opened the package and found the air filter in a sealed bag with the manual on top of the unit. After inspection, no damage to gauges were evident. I'm assuming Makita started shipping in the sealed bag after the complaints. There was a however small cosmetic dent on the top tank on the end of the tank the size of a nickle. No scratches, just a small dent. Not surprising once I looked at the shipping box. Not a big deal for me, hardly noticeable. The unit does not look used or reconditioned so I'm assuming it happend during shipping. Not worth the phone call to Amazon as it is small and will not effect performance. It did not effect the rating. Even if I bought it at Home Depot, I wouldn't have returned it due to the dent. It is after all a compressor, not a Porsche. I will dent and scratch the heck out of this thing so that's why I wasn't concerned about a small dent. Oily Case There was a light film of oil on the unit though which I cleaned up with a rag. The unit comes with about 10 oz of oil which was sealed with no evident spillage. I recommend you open the package outside or in the garage so your carpets and/or furniture are not effected. Setup I filled the unit with the entire bottle of oil as instructed, opened the valve under the tank, turned it on and let it run for 20-mins to set the piston and lubricate the unit as instructed. The tank fills fast. Both tanks filled from 0 - 130 psi in 1 min 21 sec. Noise First thing I noticed was this thing is extremely quiet for a compressor. You can carry a conversation in the same room without raising your voice. It's really incredible. Size The size of the unit is around 2' x 2; x 2'. Nice size. If you have to move around a lot, this is not the tool for you. Great if you only have to move it once, maybe twice a day. The smaller compressors, (one hot dog tank), do not have the pressure and power I needed, this one is perfect size for home use. Power If you use a lot of air ratchets, this may not be the best unit. Check the CFM rating on your tools before buying. This compressor offers 4.2 CFM at 90 PSI. Pretty good compared to the rest of them. Weight The unit is heavy as many have posted. Obviously it's well made from steel, not a plastic rattling piece of crap like many of the other compressors out there which is something I respect. I would rather have something heavy and well made then a light piece of junk that will just break down. I'm not worried about that too much as I decided to just go with longer hoses, (100') to I don't have to move it much unless going another level. I transport it with a collapsable (small) dolly from the car to the site. It weighs about 80 lbs. I am going to make a small furniture dolly for it so it can be moved easily on carpet or cement. Functionality The unit well laid out. The gauges are easy to read, the unit is well balanced with the handle, low vibration, it has rubber feet to prevent marring and reduce vibration. I'm a little nervous about the on/off switch. It's a bit long a feels like it should be more durable. I'm just going to be careful when turning on/off. Don't get me wrong, it's not too thin, I would just wouldn't rush it with that switch. Pro's: Well made & durable Well laid out Quiet Fills fast Free Shipping Good CFM rating Low vibration No burning wrists as hot components are well protected. Oiled unit, (aids to noise reduction and longevity) Priced appropriately for what you get. Cons: Heavy, 80lbs Poor packaging, (unit may have light damage. Make sure you have a Makita servicing center close by as many have stated that Amazon will not let you return it as oil cannot be shipped due to the flammability aspect.

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 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 a very nice and compact compressor for using framing nailers. It’s not particularly light weight but the carry handle helps alleviate that somewhat. The Makita workmanship is outstanding. The compressor is quiet and fills rather fast. It holds air very well and refills so quiet you really don’t even notice it. Keep in mind, it’s an air compressor so don’t expect it to be dead silent; however, relatively speaking, it is easy to work around without having to use earplugs. I’d buy it again. Update 3/21/19: Now that I’ve had this a few months, I can say the compressor was a good buy. It hasn’t given me one problem. Be sure you’re realistic about what you intend to use this for though. I bought it to do some framing, and for that purpose it really shines. However, now that I’ve completed my 30x40 garage and decided to try this for some typical air tools (angle grinder, blower nozzle, impact hammer) I find the compressor cannot keep up. It simply isn’t meant for that type of air demand. No problem, I’m gonna buy an 80 gallon, 2 stage, 5 hp compressor for the shop. I’ll tuck this Makita away for when I need to use the framing nailer or other small tools and don’t need the huge air supply. One other thing, drain the tanks when done using. I had my compressor aired up for the day recently and used it sporadically. It kicked on maybe 5-10 times throughout the day. My point is there wasn’t a lot of air demand in 12 hours. When I drained the tanks, a significant amount of moisture sprayed out. If you leave the air in the tanks, you’ll also have moisture which will corrode your tanks from the inside. Just be sure to drain it and you’ll be fine.
