Best Air Compressor With Ultimate Buying Guide

Best Air Compressor With Ultimate Buying Guide

An air compressor is a device used to convert power into potential energy stored as compressed air or pressurized air. Air compressor is not like other sources of power because it doesn’t involve converting other forms of energy like heat.If you’re a heavy-duty mechanic, contractor, serious hobbyist, or automotive technician, it’s essential to have the best air compressor.

In this buying guide, you will get our list of the best air compressors and tips for buying an air compressor. Air compressors can be used to play vital roles, such as providing torque and rotation power. The power generated will be used in pneumatic tools like brushes, drills, screwdrivers, nut runners, and riveting guns.

Air Compressor Buying Guide

If you’re looking to buy the best air compressor in the market, there are several criteria to look at. These criteria help you get the right compressor you need for a specific purpose. Consider these criteria below and make an ultimate decision before you buy an air compressor.

Horsepower (HP)

If you need to buy an air compressor with sufficient power for the tasks you want to do with it, consider its horsepower rating. Horsepower rating stands as the best way to determine the size of the compressor.

Unfortunately, you will come across marketing guys who exaggerate the horsepower rating of the compressor. Nevertheless, there is an advantage because when you consider industrial compressors, they are rated accurately. That’s why you will find that a 5 HP compressor from the industry is expensive and more prominent than the overrated type of 5 HP compressor.

If you want to be sure you have the real or overrated HP, look at the much power is used to run the machine. If it is an actual 5 HP motor, it should draw 24 amps from the 220V circuit. Overrated hobby compressor, on the other hand, it will run on 15 amp from a 110V circuit. That’s the easiest way to know the difference between a real horsepower and an overrated horsepower type.

Besides, electric and gas motor HP is rated differently. That’s because it can take 10 HP gas types of compressors to produce the same air pressure, similar to a 5 HP electric compressor.

Air Pressure (PSI)

Air pressure is another feature to look at before you purchase an air compressor. It is rated in PSI or pounds per square inch. For most air tools, they need more than 90 PSI for them to run efficiently but to get such a PSI, then look for a 12v air compressor having higher shut-off pressure.

You will find most industrial compressors to be two-stage, and thus, these build up the shut-off pressure through two stages. For the first stage, it will build about 90 PSI while the other to 175 PSI. However, smaller and hobby commercial-duty air compressors are single-stage; therefore, they will shut off between 125 – 135 PSI. It might sound like much air pressure; however, the tools might kick in at 100 PSI. If you consider such, there will be pressure drop from restrictions in couplers and hose, meaning you will not have sufficient pressure for the tool.

CFM – Cubic Feet per Minute

Air tools will require specific air volume for them to keep working. The air volume that a compressor will produce is rated in CFM or cubic feet per minute. If you look at different air compressors, you’re likely to see different CFM ratings. Sometimes, you can find a high rating for displacement cubic feet per minute and if it is calculated depending on the speed and size of the compressor pump.

The rating doesn’t determine the efficiency or inefficiency of the pump. What is essential for smaller compressors is having more than 90 PSI rating because such pressure can run numerous tools.

Nevertheless, be cautious because CMF ratings are highly exaggerated, like the HP ratings. Therefore, you should get 3 – 4 cubic feet per minute per real horsepower at 90 PSI.

Air Compressor Tank Size

The air compressor tank size will not matter much when choosing the best air compressor to buy. The tank is not responsible for producing air but only plays a significant role in storing the air. Therefore, you need an air compressor with a big pump and motor such that if it can produce enough air you want to use, you will never run out of the air, no matter the size of the tank.

Nevertheless, in some situations, you can have your money by having a small compressor equipped with a large tank but only use the air intermittently. It means that if your compressor can produce 10 CMF continuously, it means you can take from the tank 20 CMF with half the time.

But if you have to stay run your tool, like a sander, then the air compressor has to produce enough air. If it has a smaller tank, it is portable and can get pressure quicker. The large tank, on the other hand, will often start and stop but cool the air better. When the air compressor has a large tank, that does not imply it runs less; it will run the same even if it has a smaller tank, only that it will start and stop less time. The tank size is measured using US gallons.

Single-Stage & Two-Stage Air Compressors

A single-stage compressor refers to the type of compressor having a single or more cylinder, but each cylinder will pump the air directly to its tank.

On the other hand, a two-stage type of compressor will at least consist of two cylinders. Air will be pumped from one of the cylinders to the other and then pumped into its tank. In this type of air compressor, the pump will move its air through the cooling tube into the cylinder at 90 PSI and then into its tank at 175 PSI.

If you are looking for air pressure with higher pressure, it is the main reason to purchase a two-stage type of air compressor. Unfortunately, not many DIY applications will ask for high pressure. It, therefore, means you might not require the two-stage compressor.

Some believe that having a two-stage compressor is better in quality, but it’s not necessarily true. For most 5 horsepower and large industrial compressors are usually two stages. However, such are better compressors because they have been built with industrial standards in mind and not because of their type. Depending on your applications, it is best to have an excellent single stage compressor quality instead of having a big box and low-cost two-stage compressor.

Duty Cycle

It is essential to look at the duty cycle of the air compressor before you buy it. It comes expressed as a percentage. The duty cycle will tell you the minutes an air compressor will run within 10 minutes. If you look at a low-quality hobby type of compressor with a 50% duty cycle, it means that the compressor should not runs 5 minutes or more within 10 minutes. When you exceed the compressor’s duty cycle, it means the pump will be too hot, making it not last longer as expected. Many industrial compressors you come across will have a 75% duty cycle where others have 100% and, therefore, suitable to run them continuously and efficiently.

You should choose an air compressor having the best duty cycle. If you have two air compressors, one with a 50% duty cycle and the other 65% duty cycle, assuming you want to paint a barn, at the end of the day, you’re likely to have 30% more with the 65% duty cycle air more.

However, assume that the two spray guns will require 10 CMF, it means that when you use a 50% duty cycle compressor, after every five minutes, you have to wait for 5 minutes. However, the other 65% duty cycle could paint for about 6.5% minutes but wait for 3.5 minutes before you can start to paint again. And that’s a 30% increase.

Life Expectancy

Imagine saving 20% to buy an air compressor in a local big box store or buy an industrial economy compressor that will last half of another compressor? Do you think you will have saved anything? Many contractors brand types of compressors are designed to last 10 times longer and only have little difference in their price.

If you want to buy yourself a compressor, avoid buying until the dealer tells you the life expectancy. And in case the dealer does not know, he should call the manufacturer to confirm. You should ensure that in every dollar you spend to buy a bigger or better compressor, you should save about 2-3 dollars in the long run.

Despite buying the best quality compressor for you to get a long life expectancy, also buy a bigger compressor. If you require an air compressor with 10 HP minimum in size, purchasing a 15 HP compressor helps to stay a lot cooler, and it is likely to last twice long. Therefore, when you’re buying an air compressor, consider its cost per hour depending on its life expectancy.

Moisture Problems

If you compress air, it will get hot, and after the air cools, water condenses from the air. The harder you will work with the compressor, the more it will get hotter, giving you more moisture problems. Therefore, the best way to solve moisture problems is by choosing to buy a bigger compressor as it will not work hard to get hot. Besides, humidity in the air is another factor that might cause inconsistent moisture problems. That’s why the air compressor usually has a low spot where it collects water. The system has a design such that it can collect water droplets and not water vapour. If the air will be hot, it carries moisture through, and water vapour condenses in the hose.

Nevertheless, the trick is you get the air cooler before it can get into the moisture trap, and if it will cool from the trap, it means more moisture has to condense out. Desiccant dryers stand out as a great way to remove moisture. The air compressor will use silica, which helps absorb the air moisture, and silica gel will be replaced or even heated after saturating.

FAQ: Air Compressor

If you have a hard time picking the best air compressor, read these frequently asked questions.

What Size Do I Need of Air Compressor?

The size of an air compressor runs between 1 gallon to 60 gallons. It is a size that determines the period air tools will run before the motor turn back and generate more compressed air. Depending on the tools you want to use, air tools such as sanders and grinders will require continuous flow, therefore demanding an air compressor with a large tank. However, those tools are operating in short bursts and include framing nailers and brands. Nevertheless, the lesser time the motor will turn on and off, the longer the lifespan.

Which Air Compressor Is Right For Me?

If you want to have the right air compressor, there are factors to consider: First, know the projects you will do with the air compressor, such as home upgrades, automotive repair, among others. The other factor in determining the right air compressor is the tool you want to use. Some tools are requiring bigger tanks to supply more airflow, such as sand blaster. But if you’re going to operate a smaller tool like a brad nailer, even a small compressor is efficient.

An air compressor will operate through an electric or gas-powered motor. The motor helps convert electrical energy to form kinetic energy, where it takes that air around the machine. After that, it will draw the air into a tank, and the pump will pressurize it up to the correct operating pressure of the device.

How Does An Air Compressor Work?

The air compressor tank will store the pressurized air. When you trigger the tool you’ve connected on the airline, stored air will run into your tool head. And the pressurized air will run the machine you’re using.

How Do I Choose The Right Air Compressor?

You need to choose an air compressor depending on your needs. If you’re a contractor, you need a powerful air compressor to pressurize between 150 to 200 PSI. But, such a large air compressor will not be suitable to use at home.

If you need an air compressor for DIY projects, choose a smaller unit that can provide you between 125 – 150 PSI. However, if you want to use plenty of tools, choose an air compressor offering you top performance.
