What Is Air Compressor Pressure Switch? How Does It Work?

An air compressor pressure switch is a super important part of your air compressor. It’s like a button responsible for adjusting the compressor’s pressure level. Using this switch, you can change and set the pressure level according to the specific pneumatic tools you want to run. Now, you might ponder how it works. 

Let’s have a look at how an air compressor pressure switch works!

The air compressor pressure switch has a small piston that is connected to the tank. As the pressure fills up in the tank, it turns the piston on. The pressure switch has two control systems;

  • Cut-in Pressure: It is the minimum pressure that the switch needs to activate the motor. 
  • Cut-out Pressure: The maximum pressure at which the switch turns off the motor. 

When the pressure in the tank is too low, the switch will turn on the motor to start filling the tank. As the compressor works and pressure goes up, the switch turns off the motor and stops filling the tank. So, it is how the air compressor switch works. Now, it’s time to discuss “How to adjust the air compressor switch.” 

How to Adjust Air Compressor Pressure Switch?

As we have discussed earlier, adjusting the air compressor pressure switch is an important task to ensure the optimal performance of your compressor. But what is more important? It is the correct adjustment. 

Although it’s not difficult to adjust the switch, you must know the proper method. Otherwise, it can result in a mess. Don’t worry we are here to guide you! Keep reading to learn “How to adjust the air compressor pressure switch.”

Safety Precautions

Before you start adjusting your air compressor pressure switch, ensure your safety. Remember, safety comes first! Here are some simple yet important safety precautions you should follow when adjusting your pressure switch;

  • Before making any adjustments, make sure to turn off the compressor. Unplug all electric supplies. 
  • Don’t forget to wear appropriate protective gear, such as safety goggles and gloves. It will keep you protected from any potential hazards.
  • Also, read the user manual or manufacturer’s guidelines. It will help you understand the compressor model and features in a better way. 

Materials Required for Adjusting Air Compressor Pressure Switch

Now, let’s talk about what you need to adjust your air compressor pressure switch. Here is a good news for you. Guess what? You don’t need any fancy or expensive material for this pretty important task. With some simple equipment, you are all ready to set the pressure switch. Here is a list of materials you need for this task;

  • Adjustable wrench
  • Screwdriver, you can either opt for flathead or Phillips. It basically depends on the type of pressure switch. 
  • Pressure gauge. It’s optional and also depends on the type of switch. 

Steps to Adjusting Air Compressor Pressure Switch

To make your task simple, here we have listed the steps to adjust the air compressor pressure switch. Let’s have a detailed look at these steps to adjust the pressure switch like a pro;

  • Locate the Pressure Switch

The first and foremost step is to locate the pressure switch at your air compressor. It is mostly located near the compressor tank. However, this location can differ based on your compressor model. 

  • Decide your Pressure Range

After you have located the switch, it’s time to decide the pressure range. Your task and tool will determine what pressure you need. To run heavy tools, you must go for high pressure for efficient performance. However, for small tools and simple tasks, you can set your compressor at a lower pressure range. To decide the pressure range, it is best to check the tool requirement or user manual. 

  • Check the Current Pressure Setting

Use a pressure gauge to measure the current pressure in the compressor tank. Make sure it is within the acceptable range. If not, you can adjust it according to your tool. 

  • Identify the Adjustment Screws

Now, it’s time to adjust the screws. Most pressure switches have two adjustment screws, as we have mentioned above. One is for cut-in pressure (the pressure at which the compressor turns on), and one is for cut-out pressure (the pressure at which the compressor turns off). 

  • Adjust the Cut-in Pressure

First, you need to adjust the cut-in pressure. Using an adjustable wrench, turn the cut-in pressure screw clockwise to increase the pressure or counterclockwise to decrease it. It is always a good idea to make small changes. Always check the pressure after each adjustment until it reaches the desired cut-in pressure.

  • Adjust the Cut-out Pressure

Then, adjust the cut-out pressure. For this, follow the same procedure as above to adjust the cut-out pressure. Again, make minor adjustments and test the pressure after each adjustment.

  • Test the Compressor Operation and Make Fine Adjustments

After setting both cut-in and cut-out pressure, you should check the compressor operation. It will help you ensure that you make the right adjustments. If required, you can again make fine changes. 

So, this was all you need to know about how to adjust air compressor pressure switch. Now, you are all ready to make any changes to your compressor’s pressure switch to increase its optimal performance. 

Wrapping Up!

In conclusion, adjusting the air compressor pressure switch is simple. With the necessary knowledge and equipment, you can easily adjust the pressure switch. Remember, adjusting the pressure switch is not a fun game. It is important for the optimal performance of air compressors. 

To adjust the pressure switch, locate the switch near the tank and then adjust the cut-in and cut-out pressure. Make sure to adjust the pressure in a range according to the tool you want to run. Moreover, to avoid any hazards, make sure to follow proper safety precautions. 

FAQs

  • Why Do you Need to Adjust the Air Compressor Pressure Switch?
