How long does an air compressor takes to fill?

by Ivan Sanchez | Last Updated October 15, 2022

Don’t want to juggle up with an air compressor or wait for hours to see it fill the tank. But at the same time, you don’t have any idea how long an air compressor takes to fill. You must be a beginner or the one thinking of making a purchase because you’ve heard a lot about the air compressor’s performance and efficiency.

An air compressor is a machine that has the effect of compressing the volume of gas in order to raise its pressure. A particular variety of gas compressors is known as air compressors. Concerning so, this air and pressure need to be filled first in its tank.

That’s what we are going to talk about, from how long does an air compressor take to fill and what are those factors on which it is dependent, but that’s a secret. So, let’s start and reveal it slowly and gradually.

How long does an air compressor take to fill?

For a small compact air compressor, it would take approximately 10 to 15 minutes to raise the pressure to the required 35 pounds. The small compressor that I am currently using will primarily be used for the maintenance of automobile tires.

On the other hand, if you are talking about a bigger air compressor, it will take you almost 25 – 30 minutes for a greater psi level. To have an exact calculation about the time, your device will consume. Follow the things mentioned below to calculate:

  • The tank size.
  • Atmospheric pressure.
  • CFM rating.
  • Final pressure & initial pressure.

But, to have a piece of generalized information, you must know about all the factors that you should follow while making this calculation.

Factors on Which Filling of Air Compressor Depends

1. Tank size:

The amount of time necessary to fill the tank is directly proportional to the tank’s capacity. The volume of air that may be held in the tank at any given moment is directly proportional to the size of the tank.

Therefore, if you require a huge quantity of compressed air in a short amount of time, you should think about selecting an alternative that has a larger tank.

2. Temperature of compressor:

There are two types of temperature on which the performance of the compressor is dependent. Here I am saying the performance because it is correlated with the amount of time you will be required to fill the tank. Let me tell you how!

If you are using compressed air that is pretty cold, it can be because of the cold temperature, and you also must keep in mind that if it’s cold, there must be moisture in the tank, so you will require more time than usual.

Since hot compressors are already heated, they do not require any additional time for cooling down, and as a result, they do not have a tendency to have any issues with moisture, so they are quite easy to go.

Also, if your compressor requires oil or other lubricants, remember that its life span may be impacted by the lower temperatures over time. For this reason, it is vital to think about how long it will take a particular type of air compressor to fill when the temperature is lower than usual.

3. Pressure of compressor:

The third main factor is the working pressure of the compressor because the working pressure of an air compressor will have an effect on the amount of time it takes to fill the tank. This is because more time is needed for that particular pressure range if you need a large amount of air all at once.

Concerning, an air compressor works from a pressure range of 30 to anywhere to 200psi. If we talk about highly effective and most used compressors, they work at 150PSI.

In addition, after using compressed air, any tank will need some more time to become ready for usage before it can be opened again. This is due to the fact that the container needs to pressurize itself once more before it can be utilized once again.

4. Drive used for compressor:

Lastly, we have the most uncommon factor on how you are filling the tank; it’s not about which tools you are using but solely the method of filling. There are basically two different methods for filling the tank. These include:

  • Direct drive
  • Belt drive

Direct drive method:

In a direct-driven method, if you want to get the most out of the compressor, you have to let it blow while it fills up. This method is a little less efficient but a relatively cheaper option. If we talk about its usage, so if you want to be on a budget and can afford the pumping mechanism, then you can go for it, and yes, people do use this.

Belt drive method:

In a belt drive method, compressors are able to fill tanks that demand greater pressures, so you can use it for heavy load compressors, too, as it works great. However, the method typically takes significantly longer for compressors than it does for others.

On the other hand, this method is more effective and easier on the pockets too, so as compared to the first one, customers prefer to use this one. So, talking about the time it will take you is completely dependent and rely on the type. It’s always wise to make a decision after doing all the research.

Final words:

Air compressors are highly effective tools for doing any type of your task; all they require is the backend knowledge from how they work to how much time it takes to fill the tank. If you have all the knowledge, even if you are a beginner, I am sure you will never get into a problem.

But if you ever get into one, we have all the solutions for you on our website. Just write the problem, and you will be provided with a full-fledged solution. That being said, thank you for reading out. We wish you good luck with your purchase!
