Buying Guide: Things To Consider When Select 20 Gallon Air Compressor

20 Gallon Air Compressor

a) Tank Capacity

When shopping for an air compressor, you’re bound to run across this issue. To assist you, we’ve compiled a list of frequently asked questions below.

Assuming you’re looking for a 20-gallon air compressor, you’ll be looking for an air tank that’s big enough to store that much compressed air. However, the amount of air in this tank may be used relies on the pneumatic equipment you are using to power up.

b) CFM Rating

Consider the CFM rate while comparing different models of air compressors. Cubic Feet per Minute (CFM) is a unit of measurement for the amount of air produced by an air compressor. For pneumatic tools that require a high CFM rating, this can be a big help.

At varying PSI levels, an air compressor’s CFM rating changes. When the air compressor’s air tank pressure rises, it tends to be greater at lower PSI values and lower as the pressure rises. An air compressor rated at 5 CFM or more is common in 20-gallon air compressors.

A compressor that can generate 20% greater air flow than the equipment you’re powering up is often necessary. For example, if your current tool requires 2 CFM at 90 PSI, then you should look for a device that provides at least 3 CFM at 90 PSI. In most cases, CFM requirements may be found in the package specs. As well as on the brand’s official website.

c) Maximum Air Pressure

An air compressor’s pressure limit and tank pressure may be determined by looking at this, making it an essential part of the inspection process. For those who need a high air pressure for a specific purpose, this is even more critical.

Psi (pounds per square inch) is the standard unit of air pressure (PSI). Air tools may be powered up using most air compressors. As an example, a 12″ inch twin hammer wrench needs 90 PSI. Almost all 20-gallon air compressors have a maximum PSI of 120. Makes any tool strong and easy to use at once. It is, however, possible to power up as many tools as possible if you purchase a PSI that is greater than normal.

d) Motor Power

You should also have a look at the air compressor’s motor power before purchasing it. Your air compressor’s strong motor makes it useful for a wide range of people. In an air compressor, the motor is responsible for storing the compressed air within the air tank. Nonetheless, this procedure might take a long time due to the vast size of the air tank and the high air pressure inside of it,

High motor power can be quite useful depending on how rapidly you drain the tank. It’s important to remember that an air compressor with a larger motor power may fill the tank considerably more quickly. The temperature can, however, rise to dangerous levels. Single-stage compressors range in horsepower from 1 to 5, whereas two-stage compressors range in horsepower from 1 to 14.

e) Duty Cycle

When selecting a compressor, this is a crucial factor. The number of times a compressor may operate in a 10-minute period is often expressed as a percentage.

Compressors, for example, can run for more than 5 minutes in 10 minutes with a duty cycle of 50%. Generally speaking, industrial-range compressors have a 75% duty cycle or more. And some can even go all the way up to 100%, which means that you may operate them for long periods of time without experiencing any overheating difficulties.

An example of how duty cycle might benefit you is presented below.

So, let’s say for example that you and your friend are assigned to paint a barn with the use of a 10 CFM compressor. As compared to your friend, your air compressor is operating at 65 percent of its capacity. Then, you may paint for 6 12 minutes, wait 3 12 minutes, and do it all over again. For your friend, he can paint constantly for 5 minutes and then wait another 5 minutes before he starts again. ”

An air compressor with 100% duty cycle can run for longer than a compressor with 75% duty cycle, for example. So, if you’re willing to spend a bit extra, you can get a model that lasts longer.

f) Power Requirements

The air compressor’s amperage must be taken into account. Compared to portable compressors, 20-gallon air compressors have larger motors and require more electricity. In order to be functional, most of them require 120V electricity and at least 20A.

If you put a 20A compressor into a 15A circuit, you risk blowing the circuit breaker because of the voltage fluctuation. In addition, if you’re using an extension cable on a high-amperage device, it might cause the motor to overheat or limit its lifespan.

Keep in mind that you should place the compressor near an electrical outlet or install new ones specifically for air compressors. As a result, circuits that can hold their amperage can be used in this circumstance. Investing in a heavy gauge to handle the air compressor’s power needs might also be a viable option in some cases.

g) Oil Filling or Oil-Free

When looking for the top 20 gallon air compressor, this is one of the most difficult challenges you’ll encounter. It is possible to get them with or without oil.

In the air compressor market, oil-free compressors are the latest innovation. The interior components are coated with Teflon, which extends their lifespan by about 2000 hours. Using the air compressor will eventually wear down the protective covering to the point where it no longer works. The inexpensive cost, light weight, and low-maintenance costs of oil-less units have made them popular among consumers.

Oiled compressors are quieter than their oil-free counterparts. If you want to utilize a compressor in a residential or peaceful area, you should look for a quiet model.

As a result, air compressors equipped with an oiling function are able to handle increased consumption needs, or duty cycles.

So, the bottom line is that in order to make an informed decision, you must weigh the advantages and disadvantages of each option. Lightweight and low-maintenance oil-free air compressors are the norm nowadays. Because of this, it can be used for non-commercial purposes at home. For industrial and long-term use, air compressors with oiling functions are quieter and cooler, making them ideal.

h) Tank Style

Horizontal and vertical 20 gallon air compressors are available. In addition to being easier to move, horizontal compressors are also more stable than their vertical counterparts. For storage or working areas, vertical ones have a compact footprint, so they don’t take up a lot of room. Convenient for confined places, vertical compressors also provide stability.

i) Tank Material and Models

When assessing this component, you must take into account the amount of space the air compressor will take up and how portable it must be. A 20-gallon air compressor has a small storage footprint, which meets both of the aforementioned criteria.

If you’re looking for an air compressor that can be put in a garage and is mostly used for vehicle maintenance, look for a model with large wheels and a solid carriage that meets your needs.

As an alternative, if you plan on moving the air compressor frequently, choose a model with large wheels and simple mobility.

When it comes to the tank’s sturdiness and long-term viability, the tank’s material must be considered. Solid cast iron, aluminum with a cast iron covering, and aluminum are among the materials used. Cast iron is the material of choice because of its sturdiness.

j) Control systems

They make it easier for you to run the compressor.. Start-and-stop systems, constant speed controls, and others are common in air compressor models of all kinds.

k) Noise

An air compressor is a noisy piece of equipment. The noise level might also change depending on how the machine is being used and other circumstances. In general, electric motors are quieter than those driven by gasoline. Due to their greater power, gas-powered vehicles are more likely to make a lot of noise. Depending on where you want to utilize the air compressor, this might have a significant influence.

The louder the air compressor, the better it is for yard usage. Make sure to notify your neighbors ahead of time. If you’re working in a garage or workshop, noise is a significant consideration. You should go for a model that produces less noise.
