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

This question is from 4.2 Gal. 2.5 HP Portable Electrical 2-Stack Air Compressor
Asked by
Scooter B
Oklahoma City
April 14, 2013
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.

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. Read Less

Answer: 
HPLV paint guns use large amounts of air. This compressor would not be able to keep up with one. You will need a 5 HP compressor to run a professional HPLV paint gun properly.
However, there are some cheap paint guns that claim to be HPLV types that really aren't. They have small nozzles and do not use nearly as much air as a true HPLV gun. If you have one of these, this compressor probably will run Read More

Based on your previous experience with your smaller Great River compressor, it would appear that you have a real HPLV gun, so this compressor would not be sufficient to operate it. Read Less

I do have a small HVLP spray gun as well that works fine for medium to larger projects but has much less ability to narrow the field of paint spray if need.
No further answers needed unless you see one listed on sale or if Makita offers a good rebate on this compressor at some point. A close out price for a newer model would be ideal for me. Read Less

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.

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

It depends .how large is this truck tire? If it is a commercial size tire possibly . It's not the psi it's the volume and as this item does not have a very large storage tank it could do it but at the expense of the pump.

Answer: 
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.

Rated 4.7 out of 5 by 191 reviewers.
Rated 5.0 out of 5.0 by 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 ! September 27, 2016
Rated 5.0 out of 5.0 by Nice compressor Nice compressor. I use it occasionally at work to nail baseboard and trim on and numerous things around the farm. October 4, 2016
Rated 5.0 out of 5.0 by Makita This air compressor is everything I hoped it would be. I have been using it to install hardwood flooring. It is much quieter than other air compressors that I have used in the past. It has had no problems keeping up with 2, 3/4 inch hardwood nail guns. September 13, 2016
Rated 5.0 out of 5.0 by Solid Product The unit came with decent setup/break-in instructions. Needed to use the schematic to make sure the air filter assembly would be installed properly. The unit is much quieter than I expected. I have not used it much, yet, but it seems solid. It is heavy but not awkward to move around. September 14, 2016
Rated 5.0 out of 5.0 by 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. August 30, 2016
Rated 4.0 out of 5.0 by good compressor Bought this to replace a old and heavy Craftsman that started to blow breakers. So far so good no problem running a flooring nailer and finish nailer . A lot quieter and lighter. Still could use wheels to move around August 25, 2016
Rated 5.0 out of 5.0 by Nice. Compressor Compressor fills quick. Instructions for prep are bad. Does not really mention adding the oil. Nice if it had wheels. August 21, 2016
Rated 5.0 out of 5.0 by Excellent unit I have built for 46 years. This compressor is quiet, efficient (for it's tank capacity) and operates flawlessly. Weighs a ton, but the performance is well worth it. I have a Ridgid compressor and a DeWalt compressor as well, but this one is the best small unit I have owned. August 23, 2016
