The air compressor governor is a device that controls the speed of the air compressor. It is typically used to regulate the pressure of the air compressor, but can also be used to control the flow of air. The governor is attached to the air compressor and regulates the speed of the compressor by controlling the amount of air that is allowed into the compression chamber.
Air compressors are an essential tool used in a variety of industrial and personal applications. They work by compressing air, which can then be used to power various tools and equipment. However, to ensure safe and efficient operation, air compressors must be equipped with a governor.
In this article, we will explore the function of the air compressor governor, its importance, and how it works.

Has in-depth knowledge of the different types of air compressors and their uses, having worked with a wide range of clients, from small businesses to large industrial operations. Today, We’re going to discuss The Role of an Air Compressor Governor!
What is an Air Compressor Governor?
An air compressor governor is a device that regulates the operation of an air compressor. It is designed to maintain a constant pressure in the compressed air system, which is necessary for the safe and efficient operation of the compressor and the tools or equipment it powers.
The governor works by controlling the amount of air that is allowed into the compressor. When the pressure in the compressed air system drops below a certain level, the governor will open the intake valve, allowing more air to enter the compressor. When the pressure reaches the desired level, the governor will close the intake valve, preventing any further air from entering the compressor.
Why is an Air Compressor Governor Important?
An air compressor governor is essential for maintaining a safe and efficient operation of the compressor. Without a governor, the compressor could build up too much pressure, leading to equipment damage, leaks, or even explosions.
The governor also helps to ensure that the compressor is running at its optimal efficiency. By maintaining a constant pressure, the compressor can run more smoothly, reducing wear and tear on the components and extending the life of the compressor.
How Does an Air Compressor Governor Work?
An air compressor governor typically consists of three main components: the control valve, the pilot valve, and the pressure sensing element. The control valve is responsible for controlling the amount of air that enters the compressor, while the pilot valve monitors the pressure in the compressed air system. The pressure sensing element is used to detect changes in pressure and trigger the control valve accordingly.
When the compressed air system pressure drops below the desired level, the pilot valve sends a signal to the control valve, telling it to open the intake valve and allow more air into the compressor. As the pressure in the compressed air system rises, the pilot valve will send a signal to the control valve, telling it to close the intake valve and stop the flow of air into the compressor.
How Do You Check If the Air Compressor Governor is Working Correctly?
There are a few ways that you can check to see if your air compressor governor is working correctly. First, you should check the intake filter to make sure that it is clean and unobstructed. If the filter is dirty or blocked, it could be preventing enough air from reaching the compressor, which would in turn cause low air output.
You should also check all of the hoses and fittings to ensure that there are no leaks. Even a small leak can reduce the amount of air that is being delivered to the compressor, which would again result in low output pressure. If everything looks good with the intake side of things, then you should move on to checking the discharge side.
In the discharge valve to make sure that it is open all of the way. If it is only partially open, this will restrict airflow and prevent the compressor from reaching its full potential. Next, check for any blockages in the discharge line itself.
Sometimes dirt or debris can build up in these lines and cause problems down stream. Finally, take a look at the unloader valve. This valve releases compressed air when The trigger isn’t engaged, and reroutes It back into The compression chamber. If this valve Is faulty, It could be releasing compressed Air prematurely, resulting In lower overall output Pressure.
How to Test Air Compressor Governor?
If you need to test your air compressor governor, there are a few things you can do. First, check the manufacturer’s instructions to see if there is a specific testing procedure that needs to be followed. If not, you can generally test the governor by starting the compressor and then increasing the load on it.
The governor should keep the speed of the compressor constant despite the increase in load. If you notice that the speed of your compressor fluctuates when under load. Or if it doesn’t seem to be responding properly to changes in load, then there may be something wrong with your governor and it will need to be serviced or replaced.
Common FAQs – Air compressor Governor
What Does an Air Compressor Governor Control?
An air compressor governor is a device that controls the speed of an air compressor. The governor regulates the amount of air flow into the compressor by opening and closing a valve.
What Psi Should My Governor Kick in At?
Most governors are designed to activate at around 60-70 psi. If you find that your car is frequently hitting the governor while driving, you may want to consider adjusting the pressure setting.
At what psi should the air compressor governor cut in and out?
Cut-out pressures on air compressors are normally in the range of 110 psi to 130 psi, whereas cut-in pressures are around 20 psi lower.
In no more than 45 seconds, the air pressure can be raised from 85 to 100 psi. Watch the air pressure gauge as you drive to ensure correct system operation.
When do governors stop cutting?
The system’s air pressure signals the Governor to turn off the compressor (cut-out) at a certain set point. When the air pressure drops below a predetermined threshold, the Governor kicks in and restarts the compressor (cut-in).
In conclusion, an air compressor governor is an essential component of any air compressor system. It helps to maintain a constant pressure, ensuring safe and efficient operation, and can extend the life of the compressor. By understanding how the governor works and its importance, you can make sure that your air compressor is running at its best.
