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

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!

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.
