Apart from the heaviness (it weighs 59.6 pounds), users didn’t have any complaints apart from those who received a damaged one out of the package. What’s bothering is that many buyers received broken machines even though Makita promised, “every tool is thoroughly inspected and tested before leaving the factory”.

Makita has very limited warranty even though it’s not the buyer’s fault why they received a defective item. Good thing Amazon replaces the machine without questions asked.

4. ​Industrial Air Contractor CTA5090412 4-Gallon Grade Direct Drive Pontoon Air Compressor with Honda Engine

​Gas air compressors aren’t really considered “consumer-grade” compared to the all the above electric counterparts. This is because running a gas air compressor is quite costly.

Buying one itself is also costly as opposed to electric air compressor. These compressors are intended for big pneumatic tools and powering up machines for long periods of time. If you don’t intend to use it this way, then steer clear away from industrial air compressors.

The only con is the weight of this machine at 76.1 pounds. It’s difficult to transport and move in areas so you have to put it atop a wheeled pedestal or cage so it’s easier to operate it, especially if you’re a builder who does jobs practically everywhere.

Other than that, it’s a pretty good heavy-duty air compressor that is easy to maintain because of the oil-less compressor. It also run great with just little fuel, easy to start up, and has enough PSI to do a builder or DIY enthusiast’s daily job.

BUYER'S GUIDE

​Intended use

​What is the purpose of your air compressor? Are you going to be using it for heavy-duty tasks that will require a lot of power or simple at home tasks such as tire inflation, painting or anything similar?

Essentially there are two types that can accommodate you and they are either piston compressors or portable compressors, with the latter being more appropriate for less intensive and non-industrial tasks.

Piston compressors are the motor-reliant ones that build up on the air pressure when they get depleted, requiring tanks, which store the compressed air. On the opposite side of spectrum is the portable air compressor, which requires constant power in order to cycle the compressed air through the device, where they will continuously deliver air.

To delve down into further details, piston compressors can be split up further into different categories including single-stage and two-stage. Single stage air compressors work by first drawing in air, compressing it to its final pressure in a single stroke. With this you can expect to reach up to around 150psi, with the single stage having a higher CFM (Cubic feet per minute) compared to the two-stage pump.

Two-stage compressors work a little differently, although the overall concept is the same. The first step involves the air compressor bringing in air and compressing it to its immediate pressure.

It is then piped and the air is allowed to cool (usually through an intercooler) before it can progress to its second stage, where it is compressed. These two-stage compressors can reach up to 200 psi and are able to obtain this higher pressure because they are cooled in between stages.

Previously CFM was mentioned but you might be unsure of what that is or what it entails into choosing the best air compressor for you. CFM is a measure of volumetric flow that changes depending on the psi of the air compressor and is the measurement of the volume of air being transported through the air compressor. It is best to search for a compressor with a standard CFM (around 14.5 PSIA, around 68 degrees Fahrenheit, with 0% humidity).

You should also add a safety buffer of 30% on top of that depending on how many tools you will be using the compressor with and their combined SCFM. The same can be said about PSI, especially in the United States. 90 PSI (Pounds per square inch) will be the standard pressure that you require for home hardware tools to be used correctly with the air compressor.

Despite this, consider a higher shut-off pressure. Even though some hardware stores and the like will display their models with a shut-off at 125 to 135 PSI, which will not always be enough when conducting a job that requires a high amount of pressure. Overall, a greater PSI will make for an easier time using your air compressor device.

Air compressors can be large and cumbersome items, so you should consider the space you will be operating. Are you going to be working in a closed environment or will you be out in the open when you are operating your air compressor?

Alongside this even the best air compressor might be large and weighty, so is that the best choice for you if you do not want to have to carry it around with you everywhere?

​Portability

Portability is a strong trait but can sometimes be at the cost of the overall equipment power. Once again, it is at your discretion to decide what the best choice is for you and how you will be using it.

Diving further into the possibility of a portable air compressor, you must think of your power situation. You may not always be blessed with electricity when you will be using the equipment.

If you’re next to an available power source at all times then you might want to consider a drive system that contains an electric motor, otherwise it might be better to choose a gas reliant one that is not dependent on a constant electrical power source.

Gas reliant ones can be much louder than the electrical powered air compressors, so if you are working in a confined space then you might want to purchase some air protectors as well.

​Noise

​Noise may be a big issue for you. Essentially the fan and engine are the source of the noise on an air compressor, with the fan sometimes being louder. This might be a problem as the noise of the fan can mask the engine, making it difficult to determine if the air compressor is still running.

If you like to work by ear when operating this type of equipment, consider purchasing an air compressor that has a slightly louder engine so you do not run the risk of opening valves or tinkering with the device when you think it is turned off when it is actually still running the engine.

Alternatively, you should find one with an ease to access power source (button or switch) so you can turn off the machine that way and prevent yourself from taking the risk altogether.

​Tank Size

Tank size is another factor that will help you define the best air compressor for you. The tank is important, as it is the main location that the reserve air will be stored. The size of the tank does not determine the amount of air in the compressor nor does it determine the flow of the air compressor.

The style of the tank also changes depending on the type of air compressor that you purchase. It is good to know that the tank orientation will not affect the performance of the air compressor and it is merely an issue for floor space, overall size of the air compressor and the portability of the compressor (if you are intending to move it around or just keep it in one location for a large majority of its use).

If you are using the air compressor for tasks that require short intermittent bursts of air and are not on for extended periods of time then a smaller tank size is the best choice for you. Conversely, larger tanks are best for tasks that require a long amount of time operating the gas tank.

​Price

Finally there is the price of the air compressor. Initial price is not the only factor that you should consider as this can affect what the ongoing costs of maintaining the air compressor as well. Whilst a cheap air compressor may seem appealing at first, in some cases this can be more costly to maintain or not expect to reach a greater useful life span than that of a more expensive and assured model.

Adopting a rule for servicing costs can help to alleviate this. A common rule of thumb that you should follow is that servicing and energy costs will usually account for 80% of the system’s overall cost, whilst the initial purchase price will be about 20%.

​Conclusion

​As mentioned throughout, there are a lot of different features that go into the creation of an air compressor and determine how they operate. When deciding on the best air compressor you should investigate all of these features but not follow them as the be all and end all of criteria.

If you find yourself having a particularly difficult time in deciding the best air compressor for you, there are other ways in which you can get more useful information to help with your decision. If you are close by to a hardware store that has and sells air compressors, give it a visit and explain to them your situation.

There should be a sales person who will know about the compressors and give their opinion on what would be best to suit you. If you find yourself without that possibility, keep an eye out for reviews by professional reviewers or auction reviews to see firsthand what other users have said about the air compressor you want to buy.
