How to Choose Best 20 Gallon Air Compressor?

While purchasing a 20 gallon air compressor, you have to consider few things. A detail description of each factor is provided below. Read them thoroughly to understand which one suits best for your requirements.

Different Types of Air Compressors:

There are two types of air compressors – single-stage and two-stage.

• Single Stage Air Compressors – They have one cylinder which pumps compressed air directly into the tank. 120 psi is the compression of single-stage air compressor. It is suitable for light work, simple applications, sawing and nailing.
• Two Stage Air Compressors – As the name implies, they have two cylinders. Air will be moved from cooling tube into another cylinder at 90 PSI and then into the tank at 175 PSI. If you need high pressure, then this is the right choice. Some people think two-stage models are only for professional purpose but that is not completely true. It can be used for some heavy-duty residential tasks as well.

Tank Capacity:

This is one of the important and confusing things you come across while purchasing an air compressor. To help you out, we have provided a quick through below.

It is obvious that 20 gallon air compressor will have an air tank that has the capability to hold 20 gallons of compressed air. But how long the air in this tank can last depends on the pneumatic tools you are using to power up.

CFM Rating:

All air compressors come with CFM rating which is very essential to consider while analyzing the models. CFM stands for Cubic Feet per Minute that tells about the amount of air coming out of the air compressor. And this can be quite useful for any kind of pneumatic tools that need a high CFM rating.

The CFM rating of any air compressor is different at different pressure or PSI levels. It is usually higher at lower PSI values and decreases as the pressure inside the air compressor’s air tank increases. Most 20-gallon air compressors offer a CFM rating of 5 or higher.

Usually, you have to purchase a compressor that can deliver 20% more air flow than the tool you are powering up required. For example, it the tool you have needs 2 CFM at 90 PSI, then you should go for a model at has at least 3CFM at 90 PSI. CFM requirements are usually provided on the package specifications. You can also find them in the brand’s official website.

Maximum Air Pressure:

It is one of the important things to check as it provides insights on air compressor’s limit and the pressure it can handle inside the tank. This is even more important for people who are looking for high air pressure for certain applications.

Maximum air pressure is measured by pounds per square inch (PSI). Most of the air compressors have enough pressure to power up the air tools.

For example, ½” inch twin hammer wrench requires 90 PSI. almost all the 20 gallon air compressors have PSI of 120 and more. This makes easy to powerful any tools. But purchasing a higher PSI range provides one benefit – power up as many tools as possible.

Motor Power:

You should also check the motor power of the air compressor you are buying. A powerful motor in your air compressor makes it quite practical for many users. The motor of an air compressor is responsible for storing the air inside the air tank. But since the size of the air tank is quite large with high air pressure inside, this process can take a lot of time.

Based on how quickly you deplete the tank, having high motor power can be quite a bit of use. Keep in mind that air compressor that has higher motor power is capable of filling then tank much quicker than others. However, it can get hotter as well. Single stage compressors come with 1 to 5 HP while two stage compressors come with 1 to 14 HP.

Duty Cycle:

It is an important consideration while purchasing a compressor. It is usually represents in percentage format, expressing number of times the compressor can run in a 10 minute duration.

For example, a low-quality compressor has 50% duty cycle – stating that it can run more than 5 minutes in a 10 minute duration. Most of the industrial range compressors have at least 75% duty cycle. And some can even reach 100% as well which means you can run them continuously without any issues like overheating.

Power Source:

While purchasing an air compressor, you should consider whether you prefer an electric model or gas-powered one.

• Gas-Powered Air Compressors – They are best option for people who want a portable option. And moreover, they can be used easily even when no electrical outlet is available at the site. As they require gas for running, they emit fumes which are very dangerous, especially if used indoors.
• Electric Air Compressors – Compared to gas models, they are more convenient. However, you will require an electrical outlet close by your working place. They are quieter and less expensive as well. But as they are tethered to an electrical outlet, they are less portable. So, electrical air compressors are not suitable for industrial work and heavy-duty tasks.

Power Requirements:

Considering amperage of an air compressor is very crucial aspect. 20 gallon air compressors have large motors and need more power than portable compressors. Most of them require at least 120V power and 20A for providing effective performance.

If you try to plug a compressor of 20A requirement into a circuit with 15A then this fluctuation can blow the circuit breaker. Apart from that, if you are using an extension cord on high amperage devices, then it can also cause to blow or shorten the motor life.

Remember that you should assemble the compressor close to an electrical outlet or fix new ones dedicated for plugging air compressors.

In that case, you can use circuits that hold their amperage as well. In certain situations, investing in an expensive heavy gauge for supporting the power requirements of air compressor will also work fine.

Oil Filling or Oil-Free:

This is one of the most confusing tasks you come across while selecting the best 20 gallon air compressor. They are available in oil-free and oiling models.

Oil-free compressors are the new version in the air compressor market. Teflon coating is used to coat the inner components which make them last for around 2000 hours of usage.

When you start using the air compressor, the coating will start wearing off slowly and ultimately stop working. Oil-less units are well-known for their low price, less weight and less maintenance cost.

When compared to oil-free models, oiled compressors are less noisy. If you are going to use compressor in residential or quiet environment, then it is better to choose a model that doesn’t make any noise.

Moreover, air compressors with oiling feature can withstand higher usage requirements which are also commonly known as duty cycle.

So, the bottom line is that to choose the right one you have to analyze the pros and cons of each type. oil-free air compressors are light in weight and require less maintenance.

This makes it suitable for residential and non-commercial purposes. Air compressors with oiling features are quieter, durable and coolers, making them suitable for long working hours and industrial purposes.

Tank Style:

20 gallon air compressors are present in horizontal or vertical style. Horizontal compressors are easier to move around and stable as well.

Vertical ones have small footprint so they don’t take much space for storage or in the working area. Vertical compressors helpful in tight spaces and also ensure stability.

Tank Material and Models:

While analyzing this factor, you have to check out the space requirement and how portable the air compressor has to be. A 20 gallon air compressor has medium storage foot print which satisfies both the above requirements.

If you want air compressor that can be installed in a garage and mostly used for vehicle work, then check out the model that is suitable for that particular requirement, rather than the one which has large wheels and sturdy carriage.

However, if you have to move around the air compressor to your working place, then choose a model that comes with large wheels and easy mobility.

When it comes to sturdiness and durability of the tank, you have to look at the tank material. Some of the materials are solid cast iron, aluminum with cast iron coating and aluminum. We recommend to go for cast iron as it is the most durable option.

Control Systems:

They help you operate the compressor easily. Some of the control systems often found with different air compressor models are – start and stop system, constant speed controls, and several others.

Noise:

Air compressors are not whisper silent tools. The noise can also increase or decreased based on the operation and other factors. Electric motors are usually quieter models than gas-powered ones.

As gas-powered ones are more powerful so they tend to create more noise. This can have a major impact on where you are going to use the air compressor.

If you are going to use for using around the yard, then it is ok to go for an air compressor that is louder. However, make sure you inform your neighbors before-hand.

If you are operating in a workshop or garage, then noise is an important factor to consider. It is better to go for a model that generate very less noise.

Other Considerations:

• Couplers. Most 20-gallon air compressors come equipped with a single coupling system that is capable of powering one tool or piece of equipment at a time. Some, however, offer a dual coupling system that allows you to simultaneously power two items, giving you more job versatility, which is great if you share a compressor with someone.
• Noise Level. This is a consideration for anyone who uses their air compressor often, for prolonged periods, or at their home workshop during late hours. Consider getting the quietest functioning compressor you can find so you won’t risk damaging your hearing during prolonged or frequent use, or waking up other members of your household if you like to work well into the night.
• Warranty. It’s always a good idea to seek out an air compressor that comes backed by a solid warranty. Some of the best companies offer a two- to three-year warranty. We don’t recommend getting an air compressor that doesn’t at least have a one-year warranty.

20-Gallon Air Compressor Pricing:

• Under $200: This is the price range in which you’ll find the most budget-friendly 20-gallon air compressors. Most will be capable of producing up to 135 PSI and are suitable for light-duty applications only. They may or may not come with a manufacturer’s warranty. While there are several high-quality options in this price range, pickings are much slimmer than at the higher price points.
• $200-$500: This is the price range in which you will see the majority of light- to medium-duty 20-gallon air compressors. Many can produce around 150-175 PSI, making them a more powerful option for running a wider variety of tools and equipment. Most air compressors in this range will come with a solid warranty.
• $500 and up: This price range will get you the more heavy-duty single- and dual-stage 20-gallon air compressors. The more power you need, the bigger the price tag will be. Compressors in this range are more suited to garage, industrial, and agricultural applications versus personal hobby and light-duty work.

Durability and Warranty:

Since air compressors are used for various kinds of applications, you have to make sure that it is durable and reliable. This ensures that you can use the same air compressor for a long time for different kinds of applications.

And the easiest way to know about the reliability of any air compressor is to check its warranty. If it offers a 2-year warranty, then it is a highly reliable product and should last for a long time. On the other hand, any air compressor without any manufacturer’s warranty is not recommended to buy.
