How long does it take to reach maximum psi

How long should it typically take for the compressor to reach maximum psi? How long, typically, for it to reach 50psi, or 75psi? Mine seems very slow from startup.

Mediocre DIYer

Is this too much of a compressor for the average homeowner?? Indoor trim, tire filling, use as a blower will be main uses. This is pricier than most I've viewed but also seems much better. Just wondering if its too much compressor for me. Willing to pay for quality.
Asked by: Dorkwood
Is it too much ?.... Yes and no - Indoor Trim - Check pressure and CFM requirements for your finish nail gun - Tire filling - Most small compressors can handle that although slower than a bigger compressor / tank - Blower - Air guns / nozzles use a LOT of air so even the Makita will quickly turn on to rebuild pressure and probably not maintain 90 PSI unless the air gun / nozzle is used intermittently. A lesser compressor will have even more trouble with an air gun. Depends on your needs. - Keep in mind the Makita is heavy. It's a great compressor - quieter than an oil free design but the trade-off is its' weight. If you are not physically capable of lifting 77lbs you may decide this is not for you. And as others have pointed out, the carrying handle is awkward to use because of the physical size of the unit. I prefer to use two hands grabbing the frame and tanks. A hand truck helps. - Yes you are paying for quality. The Makita will probably last longer and run quieter than almost all small compressors.

What about bicycle tires at 125PSI? Is that okay with the small tanks or will it hurt the motor?

Coupling tool(s) w/ this air compressor? This might sound dumb, but can you use any pneumatic tool with this compressor?

For example, nail guns. Can I use any brand of nailer, or does it specifically have to be makita?
Asked by: DrDoItYourself
Yes, any tool with 2 things in mind: 1) you need to have an air hose with fittings/couplers. I use a rubber hose and then attach a coiled PVC hose at the end. Quick connect fittings to switch out tools, like brad nailer, roofing nailer, tire inflator. 2) Make sure that the compressor are using matches or exceeds the cubic feet per minute (CFM) rating of your tool. Usually this comes at an average based on a pressure level, i.e. 3 CFM at 90 psi or similar. Sometimes you'll think 'oh, I can run a hand sander or soething, only to find the tool needs like 18 CFM at 90 psi, but your compressor only will put out 5.4 CFM and your tank only holds 4 gallons (you can deliver the 90 psi, but you will only be able to deliver a few gallons of air before the compressor has to turn on, but then it won't keep up with the demand). Most nailers are so low in demand, that you could run two of them off the Makita at the same time (like a framing or roofing crew). You plug the hoses into the compressor, which has two ports, instead of one. I like to run a brad nailer on one hose and an air nozzle off the other one (blow the sawdust off my projects or out the open garage door

Does the Makita 2400 have Milton style V or style M couplers(air hose connections)?

I need to know what type connectors are used so that I may purchase the corresponding connectors for the air hose, air tools, etc. Maybe this info could be posted in the online product description.
Asked by: Anonymous
Never heard of type V or M. The compressor has Industrial Interchange Couplers type D

I had a Hitachi EC4 (the regulator kept going out) and I've used several other compressors over the years (including having a 60 gallon, twin cylinder). The Makita MAC2400 is by far the quietest one! I can have it running in the corner of my garage while brad nailing projects together and hold a normal converstation. It kept up with my latest deck build without a hick-up. The only issue was the weight. It was a little ungainly to pick up and move, so my buddy welded a two wheel cart for me to move it around with.

It is powerful enough to use two nail guns all day on a roofing job and yet very quiet . I would recommend this well built Makita product and look forward to not having to worry about its performance and durability .

I bought it mainly to do light auto repair in my home garage. I was close to buying the California Air tools one due to it's extreme quietness but some of the reviews on it were not good, especially the ones about it catching fire. It was an oil-less model. So I went with this Makita model instead which uses oil. It is fairly quiet itself and only runs for about 60 seconds or so to charge up the 4.2 gal. tanks from 0 psi. It charges to about 130 psi and while in use runs down to about 100psi or so before it turns back on. It is fairly heavy but I just leave it on top of my work bench and run a 25 ft. hose out of it. I never really planned on moving it around much. I have used it to do a complete brake job and it performed flawlessly. I bought an IR 1/2 " Drive impact tool (550FT/LBS) and used it with the compressor to remove the wheels and the rear bearing nuts (32mm) on my Honda Accord. No issues. I could get all 5 wheel lug nuts off of one wheel before the compressor had to cycle. I would recommend this. So far so good!

Rated 4 out of 5 by from Nice compressor, but watch for the damage from shipping. Read the reviews online about this compressor. It is heavy compared to my old compressor but the capacity is larger also. Started up, did all the break in that is required and used it for about an hour or so...I was very happy with it. The only thing (which I have read from others) is the packaging when shipped does not protect it as good as it should. My compressor had a dent in one of the cylinders, but I choose to keep it instead of returning it because odds I might get a good one, one with the same issue or worse. The dent does not effect the it except for looks...overall I would recommend it. Wished HD stocked it, so I did not have the small issue.

Rated 5 out of 5 by from Makita MAC2400 - Solidly built and nicely designed After reviewing many many reviews, and studying the specifications of all brands of small air compressors, I decided on the Makita MAC2400. After receiving the Makita MAC2400I can confirm that it is a well made and nicely designed "portable" compressor. It is relatively quiet compared to oil-free compressors and the pump is able to fill its twin tanks quickly. It is heavy though, and if you need a compressor that can be hand carried up onto a roof, this may not be the one. As with all power tools its true value, in addition to its performance, is in it's reliability over the long term. I don't have anywhere near enough run hours on the compressor in order to comment on that ,but based on Makita's construction, design and reputation, I am truly optimistic !

It was packed very well and took a minimal amount of time / effort to prepare it fore use. I have been using it for about 3 weeks now and it is doing very well. Turns out it is a lot quieter than I expected. It is a bit heavy but easily moved. The handle is well balance and comfortable to hold on to. If the initial impression is any indication of the future, then this is going to be a great piece of equipment.

Rated 5 out of 5 by from Nice Air Compressor My primary reason for purchasing the Makita air compressor was for inflating bicycle tires. It does this admirably as long as the psi is 130lbs. or less. Due to the use of oil on the pumps cylinder it is much quieter than other compressors and I imaging will have a longer life if I do my part and replace the oil at the specified intervals. Overall I'm very happy with this purchase.
