How to store a high quality air dryer for compressor when not in use?
Dec 04, 2025
Hey there! As a supplier of high-quality air dryers for compressors, I know how important it is to store these machines properly when they're not in use. A well-stored air dryer can maintain its performance, extend its lifespan, and save you a ton of money in the long run. So, let's dive into some tips on how to store your high-quality air dryer for compressor effectively.
1. Clean the Air Dryer Thoroughly
Before you store your air dryer, you've got to give it a good cleaning. Dust, dirt, and debris can accumulate over time, which might cause corrosion or damage to the internal components. Start by turning off the power and disconnecting the air dryer from the compressor. Then, use a soft brush or a compressed air gun to remove any loose dirt from the exterior.
For the interior, follow the manufacturer's instructions. Some air dryers may require you to remove and clean the filters. If so, take them out carefully and wash them with a mild detergent. Rinse them thoroughly and let them dry completely before putting them back. You can also use a clean, dry cloth to wipe down the internal parts to remove any residual moisture.
2. Drain All the Fluids
Fluids like water and oil can cause rust and corrosion if left inside the air dryer during storage. So, you need to drain all the fluids from the system. First, locate the drain valves on the air dryer. These are usually found at the bottom of the unit. Open the valves and let all the water and oil drain out completely.
If your air dryer has a refrigerant system, make sure to follow the proper procedures for draining the refrigerant. This is a bit more technical, and it's best to have a professional do it if you're not familiar with the process. Once all the fluids are drained, close the drain valves tightly to prevent any dirt or moisture from getting back in.
3. Protect the Exterior
The exterior of the air dryer is exposed to the elements, so it's important to protect it during storage. You can use a protective cover made specifically for air dryers. These covers are usually made of durable materials like nylon or polyester and can shield the unit from dust, dirt, and moisture.
Make sure the cover fits snugly over the air dryer and is secured properly. You can also use some bungee cords or straps to keep the cover in place. If you don't have a cover, you can use a large plastic sheet, but make sure it's well-sealed around the unit to prevent any water from pooling on top.
4. Store in a Suitable Environment
The environment where you store your air dryer can have a big impact on its condition. You should choose a dry, clean, and well-ventilated area. Avoid storing the air dryer in places where there's a lot of humidity, such as basements or near water sources. High humidity can cause moisture to condense inside the unit, leading to rust and corrosion.
The temperature of the storage area is also important. Extreme temperatures can damage the components of the air dryer. Try to keep the temperature between 40°F and 90°F (4°C and 32°C). If you're storing the air dryer in a cold environment, you may need to take additional steps to prevent the water in the system from freezing.
5. Disconnect Electrical Components
To prevent any electrical issues during storage, it's a good idea to disconnect all the electrical components. Unplug the power cord from the outlet and remove any batteries if the air dryer has them. This will not only protect the electrical system from damage but also reduce the risk of electrical shock.
If your air dryer has a control panel or other electronic components, cover them with a plastic bag or a protective case to prevent dust and moisture from getting in. You can also label the electrical connections to make it easier to reconnect them when you're ready to use the air dryer again.


6. Check Regularly
Even if you've stored your air dryer properly, it's still a good idea to check on it regularly. Every few months, take a look at the air dryer to make sure there are no signs of damage or corrosion. Check the cover to make sure it's still in good condition and properly secured.
If you notice any issues, such as rust, leaks, or damage to the components, address them immediately. It's better to catch these problems early and fix them before they become major issues. You can also perform some basic maintenance tasks, like lubricating the moving parts if necessary.
7. Consider Professional Storage Services
If you don't have a suitable place to store your air dryer or if you're not confident in your ability to store it properly, you can consider using professional storage services. There are companies that specialize in storing industrial equipment like air dryers. They have the facilities and expertise to store your air dryer in optimal conditions.
