How to store an oil free compressor?
Jan 14, 2026
As a supplier of oil free compressors, I understand the importance of proper storage for these valuable machines. Oil free compressors are widely used in various industries due to their clean air output, high efficiency, and low maintenance requirements. However, improper storage can lead to a range of issues, including corrosion, damage to components, and reduced performance. In this blog post, I will share some essential tips on how to store an oil free compressor effectively.
1. Clean the Compressor Thoroughly
Before storing the oil free compressor, it is crucial to clean it thoroughly. This helps to remove any dirt, dust, debris, or moisture that may have accumulated during its operation. Start by turning off the compressor and disconnecting it from the power source. Then, use a soft brush or compressed air to clean the exterior of the compressor, including the housing, fins, and intake vents. Pay special attention to areas where dirt and debris tend to collect, such as the bottom of the compressor and around the air filters.
Next, clean the interior of the compressor. If the compressor has a removable air filter, take it out and clean it according to the manufacturer's instructions. You can use a mild detergent and water to clean the filter, or you can replace it if it is damaged or excessively dirty. If the compressor has a condensate drain, open it to drain any accumulated water. This helps to prevent corrosion and damage to the compressor's internal components.
2. Protect the Compressor from Moisture
Moisture is one of the biggest enemies of oil free compressors. It can cause corrosion, rust, and damage to electrical components. To protect the compressor from moisture during storage, it is important to store it in a dry environment. If possible, store the compressor in a climate-controlled area with a relative humidity of less than 60%. If you cannot store the compressor in a climate-controlled area, you can use a dehumidifier to reduce the humidity in the storage area.
In addition to storing the compressor in a dry environment, you can also take steps to protect it from moisture during transportation and storage. For example, you can use a moisture barrier or a plastic cover to protect the compressor from rain, snow, and humidity. You can also use a desiccant to absorb any moisture that may be present in the storage area.
3. Lubricate Moving Parts
Although oil free compressors do not require oil for lubrication, they still have moving parts that need to be lubricated to prevent wear and tear. Before storing the compressor, it is important to lubricate the moving parts according to the manufacturer's instructions. This helps to ensure that the compressor will start up smoothly and operate efficiently when it is put back into service.
The type of lubricant used will depend on the specific model of the compressor. Some compressors may require a special lubricant, while others may use a more general-purpose lubricant. Make sure to use the lubricant recommended by the manufacturer to ensure optimal performance and longevity.
4. Remove and Store Accessories
If the oil free compressor has any accessories, such as hoses, fittings, or filters, it is important to remove them before storing the compressor. This helps to prevent damage to the accessories and the compressor itself. Store the accessories in a separate container or bag and label them clearly to make it easy to find them when you need them.


In addition to removing the accessories, it is also a good idea to clean and inspect them before storing them. This helps to ensure that they are in good condition and ready to use when the compressor is put back into service.
5. Perform Maintenance Checks
Before storing the oil free compressor, it is important to perform a thorough maintenance check. This helps to identify any potential issues or problems that may need to be addressed before the compressor is stored. The maintenance check should include the following steps:
- Check the compressor's pressure switch to make sure it is functioning properly.
- Check the compressor's safety valve to make sure it is working correctly.
- Check the compressor's electrical connections to make sure they are tight and free of corrosion.
- Check the compressor's belts and pulleys to make sure they are in good condition and properly tensioned.
- Check the compressor's air filters to make sure they are clean and free of debris.
If any issues or problems are identified during the maintenance check, they should be addressed before the compressor is stored. This helps to ensure that the compressor will be in good condition and ready to use when it is put back into service.
6. Store the Compressor Properly
Once the compressor has been cleaned, lubricated, and checked for maintenance issues, it is time to store it properly. The compressor should be stored in a dry, clean, and well-ventilated area. It should be stored on a stable surface and should not be placed on its side or upside down. This helps to prevent damage to the compressor's internal components.
If the compressor is going to be stored for an extended period of time, it is a good idea to cover it with a plastic sheet or a compressor cover. This helps to protect the compressor from dust, dirt, and moisture. Make sure to secure the cover tightly to prevent it from blowing off in the wind.
7. Periodically Inspect the Compressor
Even if the oil free compressor is stored properly, it is still important to periodically inspect it to make sure it is in good condition. Check the compressor for any signs of damage, corrosion, or wear and tear. Inspect the compressor's accessories, such as hoses, fittings, and filters, to make sure they are in good condition. If any issues or problems are identified during the inspection, they should be addressed immediately.
Conclusion
Proper storage of an oil free compressor is essential to ensure its longevity and optimal performance. By following the tips outlined in this blog post, you can protect your compressor from damage, corrosion, and other issues that can occur during storage. Remember to clean the compressor thoroughly, protect it from moisture, lubricate the moving parts, remove and store the accessories, perform maintenance checks, store the compressor properly, and periodically inspect it. By taking these steps, you can ensure that your oil free compressor will be in good condition and ready to use when you need it.
