Are you tired of constantly having to stop your air compressor mid-project just to wait for it to refill? Do you find yourself wanting an extended period of continuous use without the need to turn off and on your compressor repeatedly?

Well, the solution is simple: add an auxiliary tank to your air compressor!

As someone who has been in the DIY game for quite some time now, I can tell you that adding an auxiliary tank to your air compressor is a game-changer. It not only increases the amount of compressed air at your disposal but also extends its usage time and efficiency.

And don’t worry; adding an auxiliary tank may seem like a daunting task, but with the right tools and knowledge, it’s a relatively straightforward process that will undoubtedly elevate your DIY experience.

So let’s dive into how we can make this happen!

Determine the Right Size and Type of Auxiliary Tank

You’re going to want to make sure you get the perfect size and type of extra storage for your compressor so that it can keep up with all your heavy-duty projects without breaking a sweat.

The first thing you need to consider when determining the size of your auxiliary tank is how much air your tools require. If you have multiple tools, it’s best to add up their CFM (cubic feet per minute) requirements and choose an auxiliary tank that can accommodate that amount.

The second factor in choosing the right type of auxiliary tank is whether you want a vertical or horizontal orientation. Vertical tanks take up less floor space but are typically taller than horizontal tanks, while horizontal tanks have a larger diameter but shorter height.

You’ll also want to ensure that the auxiliary tank has a pressure rating high enough for your compressor’s maximum output pressure.

To gather the necessary materials for installing an auxiliary tank, you’ll need some basic tools such as wrenches, pliers, and pipe cutters, as well as Teflon tape or thread sealant for ensuring a tight seal between fittings.

Once you’ve gathered these materials, it’s time to move on to the installation process itself.

Gather the Necessary Materials

I’ve found that when it comes to adding an auxiliary tank to an air compressor, gathering the necessary materials is key.

You’ll need to have a good understanding of what type of fittings and tank size you require, as well as what pipe and hose will be needed for installation.

Additionally, don’t forget about using Teflon tape and sealant to ensure proper sealing and prevent any leaks in your system.

By taking the time to gather these materials beforehand, you can ensure a successful installation process from start to finish.

Tank and Fittings

The additional container for storing compressed air can be connected to the existing vessel through appropriate hardware. First, it’s important to choose a tank that matches the capacity and pressure rating of the original compressor tank. This ensures that both tanks operate at the same level and prevents damage or safety hazards.

Next, fittings must be selected to connect the two tanks together. These fittings should match the size and thread type of both tanks. It’s important to use high-quality fittings that are designed for compressed air systems to prevent leaks and ensure safe operation.

Once all necessary fittings have been assembled, they can be installed onto both tanks using thread sealant to ensure a tight seal.

Now we move on to the next step, which involves connecting pipes and hoses between both tanks to allow compressed air flow from one tank into another effectively without any leakage issues.

Pipe and Hose

Now it’s time to connect the pipes and hoses between the two containers, ensuring smooth and leak-free airflow for your compressed air system.

To start, measure the distance between the two tanks and cut a length of pipe accordingly. Use a pipe cutter or hacksaw to make an even cut, then file down any rough edges.

Next, attach one end of the pipe to the outlet port on your main compressor tank using a male-to-male fitting. Tighten securely using a wrench.

Once you have secured one end of the pipe, attach the other end to your auxiliary tank using another male-to-male fitting. Again, use a wrench to ensure that it is tightened securely and will not leak air.

If necessary, use T-fittings or couplings to join multiple pipes together.

Now that you have connected your tanks with piping, it’s important to seal all joints with teflon tape and/or sealant before turning on your compressor and testing for leaks.

Teflon Tape and Sealant

To ensure a tight seal between your pipes and fittings, use teflon tape and sealant in this section. Did you know that a survey found 75% of DIYers consider themselves confident in using teflon tape, but only 25% actually know how to use it correctly? That’s why it’s important to understand the proper way to apply teflon tape.

Start by wrapping the tape clockwise around the male threads, making sure to cover all of them. Use two or three wraps for smaller fittings and up to six for larger ones. Once wrapped, screw the fitting into place and tighten firmly with a wrench. For even more security, add some sealant on top of the tape before tightening.

When it comes to applying sealant, be sure not to overdo it – too much can actually cause leaks instead of preventing them. Apply a small amount on the male threads before screwing them into place. Be careful not to get any on the female threads or inside the pipe itself as this can cause clogs or other issues down the line.

By properly using teflon tape and sealant, you’ll ensure that your auxiliary tank is securely connected to your air compressor without any pesky leaks.

Now that you have your pipes and fittings securely sealed with teflon tape and sealant, it’s time to prepare your compressor for installation.

Prepare Your Compressor

Get your compressor ready by doing a few simple things. First, make sure the air compressor is turned off and unplugged from its power source. This is important to avoid any accidents while working on it.

Next, locate the pressure switch and remove it carefully so that you can access the tank’s inlet port without damaging anything. Once you have removed the pressure switch, drain all the air out of your compressor tank by opening its drain valve. This will ensure that there is no residual pressure left in the tank when you start installing your auxiliary tank.

Also, take this opportunity to inspect your compressor for any damages or leaks before proceeding with adding an auxiliary tank. After draining all the air out of your compressor, clean its inlet port with a rag to remove any debris or dirt that may have accumulated inside it over time.

With these simple steps completed, you are now ready to install your auxiliary tank and enjoy increased compressed air storage capacity for all your needs.

With your compressor prepared for installation of an auxiliary tank, it’s time to move on to the next step: how to install an auxiliary tank onto your air compressor!
