How to Refill Co2 Tank with Air Compressor

How to Refill Co2 Tank with Air Compressor? A Co2 tank has many applications like aquarium uses, and for soda machines, so its filling and refilling are needed consistently. Emptying and refilling of Co2 tank is not as difficult as it sounds. You just need the right tools for it and a little bit of knowledge to use those tools, of course. Out of those tools, an air compressor is the most important one for emptying and refilling of Co2 tank. If you use an air compressor, you will be free from the hassle of taking the Co2 tank to the store for filling and refilling. An air compressor is a quick and easy way to keep your Co2 tank filled at no cost.

Here, we are about to answer the question of “how to refill a Co2 tank with an air compressor?” Let’s move on to some steps for doing that… 

Steps to Refill Co2 Tank with Air Compressor 

1. Find the Right Fit for Co2 Tank

The first and foremost step is to find a suitable fit for the Co2 tank. The air compressor hose should fit perfectly to the Co2 tank fitting. In this way, you will have more control over the Co2 tank when you refill it. If you don’t have an air compressor, you need to own a suitable air compressor to get the job done. These are not costly and you can easily find the best air compressor under $200.

Now, start attaching the two parts, i.e. the Co2 tank and the air compressor. Screw the end of the air compressor into the Co2 tank tightly. It is important to note that some Co2 tanks and air compressors vary in fittings to help you avoid mixing the wrong gasses. If you have this type of tank, you need to get an adapter to let you connect the Co2 tank with the air compressor.

2. Draining the Tank

Your air compressor hose requires a proper compressed air fitting. After you have finished attaching the respective parts, you need to unscrew the bleed valve that is sitting on top of the fitting to remove all the air in the tank. This will increase the accuracy of filling the tank. You are required to close the bleed valve again before turning the compressor on and filling up the Co2 tank. When all the air is out, it is time to put new air in the tank from the air compressor.

3. Refilling the Co2 Tank

Refilling of the Co2 tank is done in two phases, i.e. determining the size and time, and turning on the air compressor.

3.1 Determining the Size and Time

Calculating the size and time needed to refill a CO2 tank with an Air compressor is very important before turning the air compressor on. In this way, you will know about the required air to be filled in the tank to avoid any damage to it. When you determine the size of your Co2 tank, multiple this number with 2. The number you will get is the answer to the time required by the air compressor to fill the tank appropriately. For example, if the size of the tank is 10 ounces, the air compressor will take 20 seconds to fill it with air. You need to count these seconds accurately by using a smartwatch or a smartphone or else you can damage the Co2 tank.

3.2 Turning on the Air Compressor

This phase requires you to turn the air compressor on to complete the operation. In doing so, you need to watch the seconds with great focus so you have the exact right amount of air in your Co2 tank. Knowing and monitoring time constantly is the most important part of this phase. If you are not focused enough and extra air got into the tank, it can have serious implications.

1. Finishing Off the Work

Now, you have got to the final step of refilling the air in the Co2 tank. After using the air compressor for the right amount of time and the tank is safely filled, it is time to turn off the air compressor before you finish the process. Don’t simply close it once the time ends, you need to open the valve and wait for a couple of seconds for clearing some lines and avoiding any build-up. Now, you are done, safely separate the air compressor hose from the Co2 tank. The air compressor has saved you time, money, and energy. Always be careful carrying out this procedure anytime. 

Some Safety Precautions

As safety comes first, here are some safety tips given to avoid any harm during the filling of the Co2 tank with an air compressor.

• Don’t operate the air compressor when you are under the influence of drugs, alcohol, or any such medication.
• Always be extra careful around Co2 tanks and air compressors especially while operating them.
• Handle the Co2 tank carefully and don’t drop it.
• Check for punctures to the Co2 tank and air compressor as they can be highly dangerous.
• Remove the flammable materials from the area around the air compressor and Co2 tank especially while filling them out.
• Always stay alert and focused to the time when you are refilling it.

To Sum It Up…

Refilling the Co2 tank using the air compressor can be a piece of cake when you follow the steps and precautions. Don’t panic if anything goes wrong, just empty the can and repeat the process with care. Using an air compressor for such a job is a lot easier than one might think. You can find the best air compressor almost anywhere. Remember, if you are filling a Co2 cartridge, you need an air compressor that has high pressure as the regular one will not do the job well.
