Things to Consider When Buying the 20 Gallon Air Compressors

While a perfect 20 gallon air compressor comes with excellent ability to help you out in your project, it’s quite challenging to get the good one. There are some important factors that you should consider to buy the best 20 gallon air compressor. In this section of this exclusive buying guide, we will discuss those factors. So, let’s not delay anymore and start the discussion.

Types:

The most important factor you should consider before buying a 20 gallon compressor is its type. Typically, you’ll find two types of air compressors in the market which are single-stage and two-stage compressors.

Single stage air compressors come with a single-cylinder to compress the air and transfer it into the tank directly. If you need an air compressor for light works, this could be one of the best options for you.

When it comes to two-stage cylinders, as per name suggests they have at least two cylinders. Both of the cylinders will be involved in the entire compressing process. If you are looking for a 20-gallon air compressor to help you out with your heavy-duty work, trust us, this is the right option for you.

CFM Rating:

It is one of the important things that you must look for while buying an air compressor. Typically, every model of air compressor comes with a specific CFM rating. Now, if you don’t know what CFM is, it means Cubic Feet per Minute.

This rating is quite different for different models. Given that it is important to check the CFM rating for the smooth operation of a 20 gallon air compressor, you should always check it carefully.

Maximum Air Pressure:

Every air compressor comes with a tolerance level to handle maximum pressure inside of the tank. The maximum air pressure is usually measured in the PSI unit. In most of the cases, air compressors come with a great range of air pressure tolerance. If you want to handle heavy-duty work, you should go for an air compressor that has a great range of maximum air pressure handling capability.

Motor Power:

The next thing is the motor power of the air compressor that you should check carefully before making your ultimate buying decision. You should always go for a power motor enabled compressor so that it can handle various types of work effortlessly. The motor is important as it stores air inside of the tank.

However, filling up the 20-gallon tank with air can take plenty of time as the tank comes with a large space inside of it. Now, if your 20-gallon compressor comes with a motor with high power, the filling up procedure of the tank with air will be faster compared to a low power motor.

Power Source:

The power source of the compressor, especially for those with 20-gallon capacity, is always a considerable factor. Now, there are two types of air compressors in terms of power source- gas-powered and electric air compressors. While both of the available options have their pros and cons, you have to decide upon your preferable option. Gas-powered air compressors are powered by gas and come with an excellent portability option.

You don’t need any electrical outlet to run this device as it will be powered by gas. On the other hand, electric air compressors are powered by electricity. Therefore, you will need an active electrical outlet on the job site. However, they are the more convenient options for you if you compare them with gas-powered air compressors.

Budget:

Under no circumstances, you can’t deny the importance of budget while buying a 20-gallon air compressor. You will find many products from different price ranges. But, you should always try to buy products that come under your preset budget.

In this case, knowing the price range of the air compressor will give you enough confidence to choose the best option for you. However, you should not compromise the product quality for the sake of a few more dollars.

Oil-Free or Oil Filling Compressor:

It is an important factor that might make you confused while buying an air compressor. Given that you’ll find both of the oil-free and oil filling options that come with the compressor, it is easy for you to get confused. Previously, almost every single air compressors were oil filling types.

But nowadays, the oil-free options are available in the market and can provide you with a great level of flexibility. There are many benefits of using oil-free compressors. For instance, they are less expensive, lightweight, and of course, require less maintenance.

On the other hand, oil filling compressors are specially designed for heavy-duty works and one of the added advantages of these compressors is they don’t produce high noise levels. So, you have to choose the type of compressor you want as per your requirement.

Our suggestion is to go for an oil-free compressor if you want it for residential use. But, if you need a compressor for heavy-duty projects, without any doubt an oil filling compressor will give you the most optimum solution.

Noise Level:

Needless to say, air compressors will create some disgusting type of noise. Now, the noise level of the device can be varied based on the models, operation types, and of course, there are other factors as well. In a general sense, gas-powered models produce more noise than an electric air compressor.

Gas-powered models are equipped with more powerful motors. That is why they create a lot of noise. You may use a compressor with a great noise level in your residence.

However, you must inform the neighbor about this. But, when it comes to using the compressor in a garage, you should go for an electric compressor as they produce less sound.
