How To Adjust Cut Out Pressure On Air Compressor

If you are an owner of an air compressor, you know that there are two types of pressure in an air compressor system. One is cut-out pressure, an air compressor stops at this pressure and another one is cut-in pressure. the compressor starts at this pressure. The cut-out pressure is usually higher than the cut-in pressure. But sometimes your air compressor doesn’t respond properly. You will experience the compressor will shutting off too often or not shutting off at which pressure it should stop. So, you should adjust the cut-out pressure on the air compressor. Here I am going to show you how to set it.

Adjusting cut-out pressure on the air compressor is not a difficult task if you will follow the proper guideline. In this article, I will discuss the step-by-step guidelines. Follow my writing to know more.

What is Cut-Out Pressure?

If you are a regular user of air compressors you may need to adjust the cut-out pressure at times. The compressor will turn off at this pressure. The compressor will turn on at cut-in pressure.

Find the pressure switch for adjusting the cut-out pressure. The switch is located near the tank. when you find the pressure switch try to adjust the screw that controls the pressure.

If you turn the screw clockwise it will increase the pressure and when you turn counterclockwise it will decrease the pressure. To observe the current pressure check the pressure gauge.

You may need to test a little to find the required pressure for your job. If you set it once, you have no need to adjust it very often.

How Do You Adjust Cut Out Pressure On An Air Compressor?

How do you adjust cut out pressure on air compressor?

If you have an air compressor, you may need to adjust the cut-out pressure at times. The compressor will stop running at cut-out pressure. You have to adjust the cut-out pressure if the compressor is not shutting off when it should, or if it is shutting off frequently. Here is a guideline for adjusting the cut-out pressure on an air compressor:

  • Find the pressure switch which is usually located near the air tank.
  • Then find the screw that adjusts the cut-out pressure. This screw is usually marked with a P or C for pressure.
  • Turn the screw clockwise to increase the cut-out pressure, or counterclockwise to decrease the cut-out pressure.
  • Test the compressor to see if the cut-out pressure has been properly adjusted.

Here is an example of how you might use this procedure. Let’s say that your air compressor is shutting off too frequently. You would locate the pressure switch and find the screw that adjusts the cut-out pressure. Then, you would turn the screw clockwise to increase the cut-out pressure. Finally, you would test the compressor to see if the problem has been fixed.

What Is The Best Way To Adjust Cut Out Pressure On An Air Compressor?

If you are a regular user of an air compressor, you will find the necessity to adjust cut-out pressure at times. The air compressor stops running at cut-out pressure. There is a manual that comes with each air compressor. Follow the manual of your air compressor, it will guide you to adjust the cut-out pressure of your air compressor. You can usually find the information online if you don’t have the manual.

Once you know the recommended cut-out pressure for your compressor, you can adjust it using the pressure gauge. If the pressure is too high, you can turn the knob to reduce it. If the pressure is too low, you can turn the knob to increase it.

As a real-life example, let’s say you have a compressor with a recommended cut-out pressure of 90 PSI. If you find that the compressor is shutting off at 80 PSI, you would turn the knob to increase the pressure. Conversely, if the compressor is shutting off at 100 PSI, you would turn the knob to reduce the pressure.

How Do I Know If I Need To Adjust My Air Compressor’s Cut Out Pressure

If your air compressor keeps shutting off before the tank is full, this is the right time to adjust the cut-out pressure. Here’s how to do it:

  • ¬†Find the pressure switch. This is generally located near the air tank.
  • Adjust the screws on the pressure switch. Turning the screws clockwise will increase the pressure while turning them counterclockwise will decrease the pressure.
  • Test the air compressor. First, turn on the compressor and run it until the tank is full. If it shuts off before the tank is full, adjust the pressure again and test it again.
  • Once you find the perfect pressure setting, be sure that you tighten the screws on the pressure switch so it doesn’t get adjusted accidentally.

A real-life example of this would be if you have an air compressor that keeps shutting off at 100 psi. You would want to adjust the cut-out pressure to be around 120 psi so that the compressor doesn’t shut off prematurely.

How Do I Adjust The Cut Out Pressure On My Air Compressor If It Is Too High?

How do I adjust cut out pressure on air compressor if it is too high?

If you see that your air compressor’s cut-out pressure is high then you have to take some steps to adjust the pressure. First, you need to check the pressure gauge to observe the current pressure. Adjust the pressure regulator if the pressure is above than required pressure. for that turn the knob on the pressure regulator clockwise, it will decrease the pressure.

If the reading of the pressure gauge is below the required cut-out pressure, you need to adjust the unloader valve. For that, turn the knob on the regulator counterclockwise to increase the pressure of the unloader valve.

If you finished the necessary adjustments, turn the air compressor on and check the pressure gauge reading. If it is still not at the desired cut-out pressure then repeat all the steps above until the setting is ok.

FAQ

How Do I Adjust The Cut Out Pressure On My Air Compressor If It Is Too Low?

If your air compressor’s cut out pressure is too low, you can adjust it by turning the adjusting screw on the pressure switch clockwise.

What Is The Cut Out Pressure On An Air Compressor, And Why Is It Important?

The cut out pressure on an air compressor is the pressure at which the compressor will shut off automatically. This is important because it prevents the compressor from overloading and damaging itself.

What Are Some Common Problems That Can Occur If The Cut Out Pressure On An Air Compressor Is Not Set Correctly?

If the cut out pressure on an air compressor is not set correctly, some common problems that can occur include the compressor not being able to start, the compressor shutting down too soon, and the compressor not being able to reach the required pressure.

How Often Should I Check Or Adjust The Cut Out Pressure On My Air Compressor?

The cut out pressure is the pressure at which the compressor will automatically shut off. The pressure switch is typically set to turn the compressor on at around 85 psi and off at around 125 psi. You should check the pressure switch regularly to make sure it is working properly.

Conclusion

When the pressure of the air compressor falls below the cut-out pressure, the compressor will not work. It will stop. To adjust the cut-out pressure, turn the adjusting screw on the pressure switch clockwise to increase the pressure or counterclockwise to decrease the pressure.
