A dirty air compressor tank can cause the compressor to work less efficiently and may even lead to premature failure. In order to keep your air compressor working properly, it is important to clean the tank on a regular basis.

What Are The Main Causes For A Dirty Air Compressor Tank?

Dirty air compressor tanks are a common problem, and there are several possible causes. The most common cause is simply not draining the tank regularly. When water accumulates in the tank, it can lead to rust and other problems. Another possible cause is using the wrong type of oil in the compressor and this can lead to a build-up of sludge along with other contaminants. Finally, if the compressor is not properly maintained, it can also lead to a dirty air compressor tank.

How To Clean The Air Compressor Tank:

If you have an air compressor, it is important to keep the tank clean as this will help to extend the life of your compressor and prevent rust. Below are some steps you can take to clean your air compressor tank.

Let's take a look at these steps in detail.

Check For Oil And Fluid Leaks:

The first thing you should do is to check If your air compressor is leaking or not, it needs to be fixed as soon as possible. There are a few things that could be causing the leak, so it's important to check for oil and fluid leaks.

First, check the gaskets and seals around the compressor to see if they are damaged or worn, they will need to be replaced. Next, check the hoses and connections for any leaks and finally, check the oil level in the compressor. If you find any leaks, make sure to fix them as soon as possible as leaks can cause serious damage to your compressor which can even lead to a fire.

Turn Off The Unit And Released All The Compressed Air:

It is important to turn off the unit and release all the compressed air from the compressor for cleaning the air tank. This will help to prevent any accidents that may occur while cleaning the tank and it is also important to make sure that all of the hoses are disconnected from the unit before starting the cleaning process.

Locate The Drain Valve:

Before you can do any maintenance on your air compressor, you need to know where the drain valve is located. This valve is important because it releases the moisture that can build up inside the compressor and the location of the drain valve will vary depending on the model of compressor you have. However, it is usually located near the bottom of the unit or if you can't find it then you check the user manual for it.

Place The Air Compressor In Its Original Position:

When it comes to cleaning the air tank on your air compressor, it is important to place the compressor in its original position. This will ensure that all of the dirt and debris are removed from the tank.

Open The Drain Valve To Clean The Tank:

Now open the air compressor drain valve to clean the air tank. This will help to remove any moisture that has accumulated in the tank and be sure to open the valve slowly so that you do not release all of the air at once. You may need to use a wrench or other tools to loosen the valve if it is too tight.

Keep The Drain Valve Open For Drying Out The Air Tank:

Another important thing is to keep the drain valve open for drying out the air tank. This will help to prevent rust or corrosion from building up inside the tank and additionally, it will allow any moisture that has condensed inside the tank to evaporate. It is important to note that if the tank is not dried out properly, it could lead to problems with the air compressor.

In particular, the compressor may not be able to build up enough pressure if there is too much moisture in the tank. As a result, it is important to make sure that the drain valve is left open after each use.

Check Inside The Air Tank If It Is Properly Cleaned Or Not:

When it comes to your air tank, one of the most important things you can do is to make sure that it is properly cleaned and this means checking inside the air tank to ensure that there is no build-up of dirt or debris. If you do find build-up inside the air tank, it is important to clean it out as soon as possible and once you have cleaned out the air tank, make sure that you dry it off completely before putting it back in service.

By taking the time to check and clean your air tank on a regular basis, you can help ensure that your air compressor will continue to work properly for years to come.

Close The Air Tank Properly:

If you are done with the cleaning then you need to close the drain valve of the air tank properly so that any moisture or dirt does not go into the compressor tank.


It is important to clean your air compressor tank on a regular basis to prevent rust and other build-up and by following the steps outlined in this article, you can easily clean your air compressor tank and maintain it in good working condition.
