Customer Questions & Answers

Does anyone use this for spraying paint, stain or finishes with a HPLV unit?

I am looking for a larger more capable air compressor than my little Great River unit in regards to being able to use with a HPLV spray gun. My little Great River unit works fine for filling tires, blowing dust out of woodworking equipment etc but it can't maintain effective working pressure past for some continuous spraying related functions for a full minute. I don't want to shell out $300 for something that isn't going to do much better under continuous spraying conditions. The low noise floor would definitely be welcomed however but only under more continuous use settings.
Asked by: Anonymous
Thanks for all the answers. I just noticed it appears I got my "wires crossed" in the original question. While I do have one entry level HPLV made by Rockler marketed to woodworkers it came with it's own compressor and larger diameter hose. The spray gun I was really asking about for this compressor is definitely a cheap Chinese knock off of a fairly common gun used by interior house painters but I forget the model number. if I remember right the aluminium paint container holds about 2 quarts of paint. The gun is pretty well adjustable and delivers decent results once set up right and as long as the compressor maintains adequate pressure. You just have to be very conscious of when the pressure nears that loss of performance threshold to get consistent results on larger surfaces like walls. (I have only used it on smaller over all surface areas so far) With the current two smaller compressors I have I have to stop around every four to five minutes (depending on how tight I have the needle set regulating outflow) to wait for the pressure to build back up.

The oil for the motor can you use automotive synthetic?

new to compressors ,the oil for the motor ,has to be the compressor oil only???
Asked by: Anonymous
Absolutely not. Automobile engine uses pump based (pressure) forced oil circulation system with an oil filter. In order to let the oil filter catch the metal shavings and particles, detergent or emosifier or dispersant is used to suspend them so they could be carried to the filter and stuck there. On the other hand, small air compressor uses splash base oil lubrication system without filter, which let the metal shavings and particles sink to the bottom of the oil sump and stay there, while clear oil being splashed up to lubricate all the machine parts that need to be lubricated. When you use automobile engine oil in small air compressor, detergent or emosifier or dispersant in the oil could foam or produce suds or gunk in small air compressor due to the splash or reciprocating motion of the machine parts, as well as suspend all the metal particles in the oil to damage the compressor. In summary, the key is the detergent or dispersant in the oil. Automobile engine oil has it, while small air compressor oil does not have it. Disclaimer: I am not a expert, not even a engineer or mechanics. So I just follow the manufacturer's instruction and try my best to understand it in the same time.

Will this compressor fill truck tires to 90psi?

Asked by: lowair
Yes, it runs until it reaches 130psi, then turns on again when it drops to 100psi. So you can rely on at least 100psi.

Air impact tools

Will this run inmpact tools? If so, what air impact tools besides air nailers will this operate?
Asked by: chloe
You need to check the requirements of the tools you want to operate. This model produces 4.2CFM at 90psi, with a 50% duty cycle. It will run most air tools. If you need to run something like a large impact wrench for extended periods of time you probably need a larger stationary compressor.

4.2 Gal. 2.5 HP Portable Electrical 2-Stack Air Compressor is rated 4.7 out of 5 by 207.

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.
