Air compressors are used in different types of applications and industries at present.
Whether it is providing power to automotive production equipment or offering contaminant-free and clean pressurized air to the petrochemical, chemical, and food and beverage industries, the requirement for air compressors has grown steadily over the years.
In this article, we will mention the different types of best air compressor under 500 and also how to select the appropriate one. But first, we will take a look at the different uses of air compressors right now.
What Is An Air Compressor Used For?
Air compressors are used for converting normal air into high pressurized and denser air for various uses under 3 main classifications – professional, consumer, and industrial.
Air compressors help to make sure that pharmaceutical, food, and beverage manufacturing is able to produce contaminant-free and clean products. It is also possible for compressors to provide power to sprayers, conveyor belts, packaging, and presses.
Large air compressors are used by construction sites for powering hammers, drills, as well as compactors. Uninterrupted power is produced by compressed air which is vital on remote sites without any proper access to electrical power.
Air compresses help to provide power to tractors, pumps, sprayers, as well as crop conveyors for accomplishing agriculture and farming operations. Greenhouse ventilation and dairy farm likewise need compressed air which is able to distribute clean and steady air.
The heat pump and air systems of HVAC units typically come with inbuilt rotary screw models. These help to conduct vapor compression refrigeration which requires compressing air vapors for moderating the refrigerant cycles and increasing the temperature.
The engines of automobiles consist of air compressors for cooling and heating. Apart from this, compressed air likewise is accountable for operating lots of theme park rides.
6. Energy Sector
Air compressors are also imperative for oil drilling. Dependable and risk-free drilling equipment which is air compressed is essential for the safety of the employees.
7. Spray Painting
You’ll come across many small air compressors which are employed in spray painting at present. Airbrushes usually range from bigger brushes for painting vehicles to delicate brushes for artists.
Air compressors can also be utilized for inflating tires of vehicles and bicycles, air beds, balloons, as well as other inflatables.
9. Pressure Washing
Air compressors are used for providing compressed air for pumping high-pressure water by means of water blasters and pressure cleaners for effective cleaning of brickwork and concrete flooring, plus stain removal.
10. Scuba Diving
Compressed air is also used in scuba diving with the usage of tanks which store pressurized air for enabling the divers to remain underwater for a considerable period of time.
Type Of Air Compressor
As compared to the subsequent 2 air compressor types, centrifugal compressors are known to function by means of dynamic compression.
They’re capable of producing a highly pressurized air discharged through a rotating impeller which is a process known as dynamic displacement. For performing this task, these compressor types make use of extremely high-speed rotation.
Apart from this, these are likewise oil-free compressors which imply that the oil-lubricated components are isolated from the pressurized flow of air by means of seals and vents.
The reciprocating air compressor is one particular type of positive displacement air compressor and it makes use of a piston inside a cylinder for pumping successfully and also displacing an enhanced volume of air into space till the maximum operating limit is accomplished, and the pressurized air is prepared for usage after storing.
You’ll come across reciprocating compressors in single as well as 2-stage versions offering different degrees of efficiency.
3. Rotary Screw
Similar to reciprocating air compressors, rotary screw compressors likewise rely on positive displacement.
Nevertheless, as compared to reciprocating air compressors which require valves for operation, the rotary screw air compressors make use of a couple of spiral screws which spin for effectively and smoothly guiding air within the pressurized chamber.
These sorts of air compressors require less maintenance as compared to the reciprocating compressors and they will also require less energy for operation. Moreover, they’re also the quietest air compressors at present offering the least downtime and highest efficiency as well.
How Do I Choose An Air Compressor?
Air compressors can be used for various purposes as mentioned earlier. However, there are so many models available on the market that you might be confused regarding which product to purchase for satisfying your requirements.
In the subsequent paragraphs, we have mentioned a guide for choosing an air compressor which you should go through before making a final decision.
While several of the most popular air compressors out there are oil-free, the others are not. Those which are oil-free will require less maintenance and also it will be quite easy to operate them.
Apart from this, they’re also much more inexpensive since there is no need to purchase oil or dispose of it whatsoever.
However, there are likewise some positive aspects with oil-lubricated compressors since they can be much quieter and will be able to serve you for a longer period of time.
One important aspect to take into consideration prior to purchasing an air compressor will be the amount of horsepower it has got since this will help to figure out how powerful it is.
Nevertheless, one problem is that many companies usually over-exaggerate the amount of horsepower they actually have.
Fortunately, it will be possible for you to check whether it is a genuine horsepower by looking at the amount of electrical power used by the compressor while it is operating.
3. Air Pressure
PSI on any air compressor model stands for air pressure and, on most occasions, every model will be requiring 90 psi for working efficiently. You will be able to see the amount of air pressure on the description of the product.
However, prior to using it, you should verify whether there is any obstacle restricting the hose in the compressor since this can prevent the air pressure from functioning to its maximum.
4. Tank Size
This particular aspect is not that important since an air compressor usually stores the air following which you will be using it directly. Therefore, different sizes of tanks will not restrict how much you will be capable of using the compressor.
However, it is a fact that compressors coming with bigger tanks usually tend to be somewhat more costly.
Hopefully, these above-mentioned tips will help you to come across the appropriate air compressor for you.

Whether you’re a technician a heavy-duty mechanic or a contractor, if you’re looking to buy the best air compressor for under $500 there are a series of different factors you must consider ensuring the air compressor you purchase will keep up with the tasks at hand.
What Is The Best PSI For An Air Compressor?
They measure the air pressure produced by a compressor in pounds per square inch or PSI. The vast majority of compressors on the market will require a minimum of 90 PSI to run effectively. But to maintain this level of pressure, your air compressor will have to have a much higher shutoff point.
The vast majority of compressors on the market are two-stage devices, which means they shut off between two pressure points. The first being 90 PSI and usually, the second stage will build to 170 PSI.
If you’re looking for a smaller lower duty compressor or a hobby compressor, you could work with a single-stage shut off that operates between 125 and 135 PSI. I know this sounds like ample air pressure.
But that they usually kick in around 100 PSI if they encounter any drop-off or restrictions in the couplers or hoses you quickly find out that these compressors don’t provide you enough pressure.
Which Is A Better Oil Or Oilless Air Compressor?
Whether you’re going to choose an oil-less or oil air compressor will not be down to what you intend to use the device for.
Oil compressors will require more maintenance than oil-free ones because the oil will need changing occasionally, depending on how much it’s used and the design of the device.
Oil-lubricated compressors are also much heavier than the oil-free ones, making them less portable. Oil-less compressors are cheaper as they comprise fewer moving parts and the design is more simple.
Having said all that although an oil-less compressor is lighter, cheaper and requires lower maintenance they are far less durable than oil air compressors.
An oil compressor that is pre-lubricated will maintain constant air pressure much longer than an oil-free compressor. If you intend to use your compressor for a non-commercial purpose then an oil-free compressor should work perfectly.
But if you’re using one for industrial purposes and it will be used for long working hours, then an oil-less compressor will not last the pace.
How Often Should I Change The Oil In My Air Compressor?
How often you need to change the oil in your air compressor will depend heavily on the compressor you buy and how much you use it. Some brands of compressors need oil changes more frequently than others.
As they design every brand of compressor differently to get the most accurate information about oil changes, you must consult the user’s manual.
But experts will tell you that anyone working with a reciprocating air compressor, they should change the oil every 3 months and if you’re using a rotary screw compressor, you should service every one to two thousand hours.
How Long Do Air Compressors Last?
Because of the complex nature of their design, tools such as air compressors regardless of their quality or brand, it remains difficult to estimate the length of their lifespan.
The vast majority of high-end air compressors are oil-based, and the oil is important as it acts as a lubricant to prevent the moving parts of the device from wearing because of friction.
One of the most important parts of your maintenance regime is ensuring that the oil in your compressor is changed regularly.
Doing this will ensure it will not lose its ability to lubricate itself efficiently. After you purchase your device, change the oil after 10 hours of use top it up every 20 hours after that point, and approximately every 120 hours completely drain your device and change the oil.
Outside of changing the oil you should check that all the fasteners on your device remain tight if you’re consistently using your air compressor any loose nuts or bolts can directly affect or damage the device because of the vibration that is constantly produced by the engine’s operation
Checking its intake for dust will prevent the engine from overworking and overheating. The easiest way to do this is to perform regular maintenance checks, cleaning the air filters where needed and replacing them if required.
Most air compressors will automatically switch off when they run too hot and this will cause them to produce fire lower pressure than usually required.
If you follow a regular maintenance regime, you can expect a well oiled and maintained air compressor the last anything from 10 to 15 years.
How Often Should An Air Compressor Be Serviced?
Even with regular servicing and maintenance, your air compressor should be professionally serviced at least every 3,000 hours are at a set interval of 6 to 12 months.
Regularly changing the oil and removing contaminants from elsewhere will help you keep your device contaminant free and running smoothly.
If your air compressor experiences a high level of activity, carry out a service every 6 to 9 months. On the flip side, if it’s only infrequently used a service every 2 years, maybe enough.
Ultimately, the decision to service your air compressor will be down to the number of working hours they use it in a 3-month period.
Getting your device professionally serviced will involve the following:
- All fasteners will be checked, replaced if needed, and tightened
- All hoses will be checked and replaced if needed
- They will run a full safety test on the device
- They will clean the fuel tank
- They will change the compressor oil
- The separator element will be tested and changed if needed
- The filter will be checked, cleaned and changed if needed
- It will clean the heat exchangers
This article will cover some frequently asked questions to reveal some important information that should help you choose the best air compressor under 500 you purchase.
