Replacing the air compressor tank is necessary in the event of tank failure. With regular use, the tank gets weaker and pressure slowly decreases. If pressure drops below the required level, you will notice an air leak. When this happens, a compressor tank replacement is necessary to avoid damage to your home or office equipment.
In addition, it’s important to carry out an air compressor tank replacement when the existing tank has cracks or leaks, when air pressure does not meet the required standard, or when there is a loss of air pressure. If you are wondering how to replace an air compressor tank, keep reading for all the information you need about air compressor tanks and replacing them.
8 Steps About How To Replace An Air Compressor Tank
Most air compressor tanks are made of aluminum, but some also come in stainless steel and other materials. Regardless of the material, the tank must be checked for any corrosion or damage before being replaced. If the tank’s inner walls are corroded or dented, it may leak air or pressure and can become a safety hazard. The tank valve must also be tested to ensure it is working properly.
1. Attach The Four Feet
To replace an air compressor tank, you must first attach four feet to the front frame using standard ½ inch carriage bolts and nuts. Then, place the first nut on the feet and insert the feet into the holes in the front frame. Next, adjust the lower nut on the feet until the tank is level.
Finally, put the top nut on the feet and tighten it with two ½ inch wrenches. When replacing an air compressor tank, it’s important to test the compressor after you finish replacing it to ensure that it is working properly. This will help ensure safety and efficiency in your welding or construction work.
2. Install The Drain Tank Valve
If you are replacing the air compressor tank, you must replace drain tank valve as well as the check valve. The drain tank valve allows air from the tank to flow out of the system and prevents it from back flowing to the compressor.
The check valve prevents air from entering the tank and causing back pressure. If a check valve fails, there will be back pressure in the tank, causing high air pressure to be applied to the head of the compressor.
It can also cause the compressor not to cycle on and off to fill the tank. To avoid this problem, replace the check valve with a reliable one that is working properly. If replacing an air compressor tank is beyond your abilities, consult a professional for help.
3. Install The Regulator
It’s essential to properly install the regulator when replacing an air compressor tank. Make sure you check the regulator for any signs of wear and tear or damage before installation.
It is also important to connect the regulator to the air compressor tank according to the manufacturer’s instructions. All in all, after replacing the air compressor tank, it is vital that you check the pressure with a pressure gauge to ensure that the regulator is working correctly.
4. Install The Pressure Switch
In case you need to replace an air compressor pressure switch, it is a good idea to do so while replacing the tank air valve. This will ensure that the new pressure switch turns the air compressor pump on and off to regulate tank air pressure.
The air compressor pressure switch also acts as a check valve, preventing tank air from back flowing to the pump. Replacing an air compressor pressure switch can be done in a short amount of time and requires only basic tools and skills.
5. Place The Motor
When placing the motor, it is important to make sure that it’s properly secured to the frame of the air compressor. If not, your new air compressor tank may end up falling off or being damaged in some way. After securing the motor, it’s time to position and tighten all bolts and screws that secure the tank.
6. Install The Blue Line
To replace an air compressor tank, you must first determine when the tank needs replacing. The best way to do this is to regularly check the air pressure in the tank and see whether it drops below a certain level. If the air pressure in the tank drops significantly, it may be time for a replacement.
When installing the blue line to replace an air compressor tank, ensure that the air compressor motor is able to start when the tank is empty. This will prevent air from back flowing into the pump and causing damage. Before installing the blue line, ensure that the air compressor can run properly with a new tank installed. Unscrew the existing tank from the air compressor and install the blue line instead. Connect the blue line to the air compressor and make sure it is securely fastened.
7. Install The Power Cord
Once the blue line is installed, it’s time to install the power cord. Make sure that the two ends of the power cord are properly secured and routed so they won’t get caught on anything. Finally, plug in your new air compressor tank and test it out to ensure everything is working correctly.
8. Install The Base
After verifying that your air compressor is working correctly, it’s time to install the base. The base should be firmly attached to the ground using screws and anchors. Once installed, tighten all screws and bolts until they are fully tightened.
Why Do We Need To Replace?
A pinhole leak in an air compressor tank is a warning sign that the area of corrosion inside the tank is much bigger than the pinhole size. The pressure switch regulates tank air pressure and can malfunction, leading to the need for a replacement.
If your air compressor isn’t cycling on and off to fill the tank, the pressure switch needs to be replaced. A compressor with a pinhole leak in the tank wall should not be used until the tank is replaced. This is important to prevent further damage and maintain proper functioning.
It’s vital to replace an air compressor tank when it shows signs of rust or corrosion or when it becomes torn or leaky. This will ensure that your air compressor continues to operate properly and safely.
Troubleshooting Common Issues When Replacing An Air Compressor Tank
When replacing an air compressor tank, it’s important to check the air compressor check valve for damage and replace it if necessary. This will ensure that air is able to enter the tank without getting trapped inside during use. Next, make sure that the air compressor pressure switch is working properly by cycling the compressor on and off to fill the tank with air.
If the compressor isn’t cycling on and off, inspect the pressure switch for any signs of damage and replace it as necessary. Finally, make sure all connections are secure and free of air leaks by checking for any corrosion or signs of wear. By following these simple steps, you can ensure that your air compressor works properly and efficiently.
Conclusion
Air compressor tank replacement is an essential task to perform when the tank starts leaking air or when it gets damaged. It allows you to maintain steady air pressure in your air system and ensures it works properly.
Replacing an air compressor tank can be done by anyone with basic knowledge of tools and skills to replace a tank. As mentioned above, there are several reasons why you might need to replace an air compressor tank, so go through this list if you’re not sure.
Frequently Asked Questions
Can You Replace A Tank On An Air Compressor?
Yes, you can replace a tank on an air compressor. The steps for replacing a check valve and pressure switch are explained in the DIY repair guides for each component. Additionally, the pressure switch can be replaced in less than 45 minutes.
How Do You Fix A Leaking Air Compressor Tank?
To fix a leaking air compressor tank, you’ll need to inspect the piston seals of the tank for worn parts that may be causing the leak.
When Should Air Compressor Tanks Be Replaced?
