An air compressor is a device used to increase the pressure of air. They come in a variety of shapes and sizes, but all have one common purpose: to provide compressed air. One question that often comes up is whether or not an air compressor can be left full when it is not in use. The answer is yes, you can leave an air compressor full, but there are some things you should keep in mind.
Introduction to air compressor?
An air compressor is a machine that takes in air at one pressure and volume and increases the pressure. This is done by passing the air through one or more stages of compression. Air compressors are used in a variety of industries, including automotive, aerospace, and manufacturing.
The function of air tank in an air compressor
Air tanks store compressed air which is used to power an air compressor. The compressed air is forced into the tanks through a pipe called the inlet. As the air pressure inside the tank rises, the air pushes on the outlet valve, which opens and allows the compressed air to flow into the compressor. When the compressor reaches its target pressure, it shuts off and the outlet valve closes, trapping the compressed air in the tank.
Why air tank Gets filled with water in an air compressor?
The air tank in an air compressor fills with water because the compressor pulls in moisture from the surrounding environment. The moisture is drawn into the compressor due to the difference in air pressure between the inside and outside of the compressor. This causes the moisture to condense and form droplets, which then collect in the air tank. Over time, this can cause the tank to fill up with water, which can damage the compressor.

Can You Leave an Air Compressor Full?
People often store their compressor the way it is, leaving it full of air. It could be to store air for late use or emergency cases. Now consider the question that as far as safety is concerned, is it a good idea to leave an air compressor full. The answer is a big yes as long as you ensure regular maintenance of your air compressor.
The maintenance initially includes draining the accumulated moisture regularly from the compressor tank. So, if you use your compressor every day and maintain it daily, you can keep your air compressor full without any worry.
But a compressor that has not been used for long should somewhat be drained. You may be thinking about why it's so important to drain the compressor? We explain its necessity.
The air inside a compressor is the ambient air, meaning natural air, and our air has water vapor. The water vapor amount can be different depending on weather conditions. It can instantly increase with the increasing temperature and decrease with the decreasing heat. An air compressor can pressurize the air and compress it by taking in ambient air.
So, if it's not drained regularly, the water with dust inside can corrode the tank internally and can damage the pneumatic tools.
Why Should You Drain the Air Compressor Regularly? 3 Big Reasons
If you want to get the full out of an air compressor, you have to focus on its maintenance and, after every use, drain to remove unnecessary dust and water inside. To avoid three significant issues, you must drain the air compressor on a regular schedule.
1. For Protecting the Air Compressor:
The vital part of an air compressor is its tank which you don't want to damage in any way. Here, corrosion is the main culprit that can destroy the tank from the inside.
However, it can only cause you trouble when you have kept the leftovers of the tank for a more extended period. Dust along with water creates corrosion and thus havoc on the tank. To avoid such an issue, you better remove the leftovers every day.
2. For Protecting Equipment and Devices:
It's essential to drain your tank because it will keep itself safe from moisture and other equipment and devices. Most machinery that uses an air compressor to get power will also get water if the tank is not drained.
Some minor water droplets and boom! No, things will not explode but, of course, harm your machines and deactivate them completely. Remember to take care of sensitivity to water vapor such as valves and air cylinders.
3. For Improving the Job Quality:
An undrained air compressor can make the grade of your job go down. For example, if you work on wood, you will use woodworking applications.
Through the air compressor that has not been drained, tiny water drops can enter into them, and through them, the woods will get moisture too.
For example, airbrushing or spray painting can defect the woods visually. This way, you can even harm the metal surfaces by making a way for rust to occur.
How Often to Drain a Compressor?
How frequently you drain the system will be determined by how much you have used it and how much humidity it contains. The fact is, using the air compressor often will create more unnecessary water into it.
But don't worry. Generally, manufacturers of the product include a maintenance routine in the manuals. But several advise draining the tank on a daily basis.
Even if you face difficulties with the pumping cycles of your air compressor, you must clear the tank after every one or two days. This way, you can save the product and other machines and increase their working power.
FAQs
Do I need to empty my air compressor after every use?
One of the most important steps in maintaining your air compressor is draining the water from the tank. This is because if water builds up in the tank, it can cause corrosion and damage to the compressor. Draining water from the tank is a simple process, and it only takes a few minutes to do.
It's suggested to empty the tank of an air compressor after every use. Even though all the air compressors out there are not easy enough to drain.
So, if you have a hard-to-operate one, you can try draining it after every 2 or 3 uses. Not draining its tank over 4 or 5 days can cause water vapor and dust to form together and later harm your machines.
How long can you leave air in an air compressor running?
The amount of time an air compressor can run is dependent on the compressor's duty cycle. The duty cycle is the amount of time the compressor is running compared to the amount of time it is not running. For example, a compressor with a duty cycle of 50% would run for half of the time it is turned on.
Air compressors are capable of running for extended periods of time, but how long they can run ultimately depends on the compressor's capacity and the work it is performing. Larger air compressors can run for longer periods of time than smaller compressors, and compressors that are used to do heavier work will need to be run for a longer time than those that are used for lighter work.
Do air compressors explode?
Sadly, yes, an explosion of an air compressor is possible. This is a common incident faced by many air compressor users. The reason behind is a corroded tank.
Excessive condensation can accumulate unwanted water, which can cause corrosion inside the tank. But to avoid such an occurrence, you should drain the compressor's tank and keep it hydrated.
How to drain water from an air compressor Tank?
The process of draining water from an air compressor tank is a relatively simple one. The first step is to open the drain valve at the bottom of the tank. This will allow the water to flow out of the tank and into a receptacle below. Once all of the water has been drained, close the drain valve and refill the tank with air.
For small size compressors, you need to tilt the compressor to drain the water properly. It works fine if the motor is turned on leaving the drain valve open.

What is a drain valve?
Air Compressor Drain Valve
A drain valve is a device used to release liquid, gas, or steam from a container. Drains are used in many industries for a variety of purposes. The type of drain valve used in an air compressor is important for the proper functioning of the compressor. There are several different types of drain valves that can be used in an air compressor. The most common type of drain valve is the ball valve. One of the more unique types is a diaphragm drain valve, which is used in some compressors.
Why should you replace your air compressor drain valve?
In order for an air compressor to work properly, the air must be able to flow in and out of the compressor. This is why it is important to keep the air compressor's drain valve functioning properly. If the valve becomes clogged or blocked, the air will not be able to escape, which can lead to damage to the compressor.
This valve helps to keep the compressor in good working order by draining any excess oil or water that may have built up inside. If this valve is not replaced on a regular basis, it can cause the compressor to leak oil.
Closing Remarks
Air compressors help us a lot by giving power to some useful machines and applications. Thinking about life without air compressors means thinking about a world with no modern technology. Therefore, the use of air compressors is vast.
Some even use it for personal jobs like woodworking or painting on metal surfaces. Many people ask, "can you leave an air compressor full?" If you are one of them, I hope you have got your answers.
