Buying Guide: Air Compressor Under $500

Probably, from the above-mentioned list you could have already identified one particular air compressor that suits your needs perfectly. However, many would still have a lot of things going in their mind.

One could’ve asked questions like what would be the best 30 gallon air compressor there are in the market to replace their old one. What tools are you going to use? Or, how frequent are you going to use it? Well, these are the detailed guide and analysis to consider before you decide one.

Type of Air Compressor

First, let’s have a look at how the basic mechanic behind how various types of air compressor motor work.

The most common of all is the reciprocating type. It works much like the car engine where the crankshaft move the pistons up and down. In this way, it creates a vacuum that draws the air in and then pushes the air out. This type produces more friction and also hotter and louder when in operation.

Another type is the rotary screw. It produces high power because it maximizes air intake and air going out. The moving parts are sealed with oil and therefore produce less friction, resulting in less maintenance cost over a period of time.

Lastly, there is a scroll type. It uses two circular pieces, one rotating, while the other remain stationary to produce compressed air. Operating in the cleanest and quietest conditions, it is ideal for indoor usage where cleanliness and silence are very important.

Motor Power

To many people, horsepower of the motor seems like the only factor to consider when buying an air compressor.  No matter what other specifications and accessories available, the level of work will decide how much power is needed.

However, many will get misguided by the marketing gimmick that exaggerates horsepower rating in order to increase sales. If you look at the horsepower specification indicated on the machine, it may not be the real power it is able to generate. Luckily there is a simple way to tell if the horsepower rating is real.

You can verify it by looking at how much amps that the motor will draw.  For example, a 5HP motor will run at 24 amps on a 220 volt circuit, whilst an overrated 5HP motor can only draw 15 amps on a 110 volt circuit.

In contrast, horsepower on a gas motor will need to produce almost twice as much power to same level of power that an electric motor produces.


Buying an air compressor is not like buying an electronic gadget. A smartphone or a laptop can only be used for a short duration, like a couple of years or maybe a little bit longer due to upgrading necessity.  In contrast air compressors technology doesn’t evolve that frequent.  So after buying one, you would intend to use it for a long time.  After all, it won’t get outdated in a space of 5 or 6 years at least.

For that reason, it is important to look at the build quality and durability of the compressor. You could ask about the life expectancy of the compressor. Generally, the higher the quality, the more expensive it would be. Since it is going to be used for a long time, it is worthwhile to invest a little bit more, which in the end would prove to be a smarter decision.

Probably, it is better to buy a bigger compressor.  For example, if you need 5 HP compressor, get the with higher capacity say at 10 HP. Therefore, you would not have to work you compressor to the fullest. In the long run your air compressor would have a longer running life.

Air Pressure Level

Air pressure is normally indicated by pounds per square inch (PSI). As a general indication, an air compressor can run appropriately at above 90 PSI.  However, 90 PSI may not be enough to produce a power to operate properly. The air compressor must have a higher shut-off pressure than that in order to maintain power at 90 PSI.

Furthermore, most air compressors normally kick in at more than 100 PSI. The normal range of air pressure level for hobby air compressor is between 125 to 135 PSI. We would suggest that you look at shut off level as high as possible because you need to consider the restrictions you might have in the hose and couplers.  These restrictions will cause the air pressure to drop significantly, that you may find your air compressor will not have enough power to operate.

Air Volume

We measure the amount of air in an air compressor in cubic feet per minute (CFM). CFM rating depends on the size as well as speed of the pump.

CFM rating when the machine is not operating is meaningless. You will look at the correct CFM rating when the air compressor is working at 90 PSI or more.

Just like HP rating, CPM rating can also be exaggerated.  But as a general indication you should be looking at 3 to 4 CFM at HP rating of 90 PSI.

Tank Size

You may think that a large tank produces more power, but that is not necessarily be the case. Having a larger tank means that you can store more air in the compressor. By having more air storage you would not have to repeat the refill too often. Therefore, you can continue work for longer time.

In contrast, a smaller tank will only store smaller volume of air.  Hence, you need to rebuild pressure more often.

Therefore, you need to decide whether to opt for air compressor with small or big tank depending on the type of work you intend to do. Smaller tank is best for works with short break like air tools.  While bigger tank is suitable for job that requires less stop and go time like sanding.

Single or Double-Stage Air Compressors

There is a misconception that a double-stage air compressor has better quality compared to the single-stage one. It is not necessarily so.

A double-stage air compressor produces more pressure, like the name suggest, in two stages. Hence producing more air pressure. You would only need a double-stage air compressor if you really need high pressure for the intended work. Otherwise, a single-stage one would suffice.

Belt or Direct Drive

A belt-drive compressor is where the pump is worked through a belt connected to the motor. The belt is lubricated with oil for smooth running. By using the belt, the pump runs slower than the motor due to loss of energy in between. It normally has longer life span since there is less wear and tear. This type is more suitable for static work where you don’t have to carry the machine around or when you need more air volume.

In contrast, a direct drive air compressor is directly attached to the motor. Since the pump runs as fast as the motor, the life expectancy is shorter due to high wear and tear.  Furthermore it is normally oil free which produces more frictions. Some are engineered so that the pump will run faster than the motor itself, making it wears even faster.

Duty Cycle

A duty cycle of an air compressor is the duration of time that the machine can run continuously.  It is measured as a percentage of the number of minutes it can run in a span of 10 minute. For example if it can run for 6 minutes out of a 10 minute period, then the duty cycle is expressed as 60%.

So what does this figure tells you? A higher percentage would indicate that the air compressor has longer span of continuous working and shorter wait time for it to continue work again. In short the higher the percentage, the faster you can finish the job. As a result, an air compressor with high duty cycle would cost more, but it is worthwhile to get one.

Ability to Control Moisture

Moisture will develop every time you use the air compressor.  This is because compressed air will get hot and when it gets cool, then moisture will build up. The more and longer you use the air compressor, the more moisture will develop.

Look out for the air compressor that comes with moisture trap. However, moisture trap alone will not remove moisture totally, because the trap is designed to collect water droplets.  Water droplets will form only after the water vapor cools down, so some moisture will stay before it is collected by the trap.

Alternatively, it is better to get a bigger compressor, since it won’t get hot too easily compared to smaller one. Likewise, you can use drying agent such as silica gel to draw up moisture.

The Price

Off-course this is a big factor – you would also need to see how much money you would be prepared to part with.  In this guide we only list out those priced below $500, because anything above that would be considered a very high-end compressor and not really necessary for many people.

If you really on a tight budget, but in dire need of an air compressor, then you can go for the lower price at $100 to $200.  However, please bear in mind that these machines may not last that long and they normally vibrate more and noisier.

Best Brands of Air Compressor

Air Compressor FAQs

Still after going through what we have comprehensively presented thus far, you would somehow have a lot of queries.  Do not panic, we have also listed all the most important FAQs that you may find useful.

Q1: What is ‘stop-start’ and ‘constant run’?

A: A ‘stop-start’ is a switch to turn the compressor on and off with one push. A ‘constant run’ air compressor runs continuously to supply compressed air.  The stop-start type is better for household and small job uses, while the latter is more for industrial operations.

Q2: How often to change oil?

Answer: it is best to check with the manufacturer for frequency of oil change.  However, in general you should change oil every 8000 hours of use.

Q3: How often to change filters?

Answer: When tears and holes appear in the filter.  Anyway, you should clean the filter at least once a week.

Q4: Can I use a generator to run my electric compressor?

Answer: Yes you can, but it is advisable not to do so because a generator will produce uneven power, while a compressor requires a consistent power to run.

Q5: What is the one thing to ensure my air compressor lasts longer?

Answer: Just like in a car, you need to maintain it regularly and on schedule consistently.

Q6: Which power supply to run my air compressor?

Answer: For DIYers and home use, it is adequate to use the normal domestic electricity supply. You can also look at the information tab where the manufacturer indicates the Volts and the Amps.

Q7: What is meant by “capacity” of a compressor?

Answer: It is a measure on how fast your air compressor can bring air and it is measured in CFM (Cubic feet per minute).

Q8: Can I store my air compressor outdoor?

Answer: Yes, but you still need to cover it up so that it is not exposed to rain of snow.

Q9: Is it ok if water leaks in my air compressor tank?

Answer: No. Compressor tank is made of steel, so water will lead to corrosion. You don’t want that to happen at all.

Q10: How frequent do I need to service my air compressor?

Answer: It much depend on how often you use it. If you rarely use it, then it’s sufficient to service it annually. However, if you use it more frequently then it’s better to service it quarterly.
