The Dangers Of Storing An Air Compressor Empty – Here’s What You Need To Know

Air compressors are indispensable tools in various industries and DIY applications. However, the question of whether one should store an air compressor empty or filled with air remains a topic of debate. This comprehensive guide will delve into the ins and outs of this topic, providing you with the knowledge to make an informed decision.

The Case for Empty Storage

1. Prevents Corrosion: When air compressors are left filled with air, moisture can accumulate inside the tank, especially in humid environments. Over time, this moisture can cause corrosion, damaging the tank and internal components. Emptying the tank eliminates this risk.

2. Reduces Pressure Buildup: Filled air compressors can develop pressure buildup over time, even when not in use. This pressure can strain the tank and safety valve, potentially leading to leaks or ruptures. Emptying the tank releases this pressure, mitigating potential hazards.

The Case for Filled Storage

1. Enhanced Lubrication: Some air compressors rely on oil lubrication for their internal components. When stored filled with air, the compressed air helps distribute oil throughout the system, providing continuous lubrication. This can extend the compressor’s lifespan and reduce wear and tear.

2. Protects Against Cold Damage: In cold climates, empty air compressors can be susceptible to damage from freezing temperatures. The air inside the tank acts as an insulator, preventing the tank and components from freezing and cracking.

3. Easier Startup: When an air compressor is stored filled, it can be started up more easily. The compressed air provides an initial boost of pressure, reducing the load on the motor and preventing it from burning out.

Factors to Consider

The decision of whether to store an air compressor empty or filled depends on several factors:

• Type of Compressor: Oil-lubricated compressors benefit from filled storage, while oil-free compressors can be stored empty.
• Climate: Cold climates favor filled storage, while humid climates may necessitate empty storage.
• Frequency of Use: Infrequent use may warrant empty storage, while frequent use suggests filled storage.
• Storage Duration: Long-term storage favors empty storage, while short-term storage can accommodate either option.

Recommended Storage Practices

Empty Storage:

• Drain all moisture from the tank and lines.
• Leave the tank open to ventilate and prevent rust.
• Lubricate the compressor according to the manufacturer’s instructions.

Filled Storage:

• Fill the tank to its recommended pressure.
• Add oil to the compressor as needed.
• Seal the tank to prevent moisture buildup.

Takeaways

Whether to store an air compressor empty or filled is a matter of balancing the risks and benefits associated with each option. By carefully considering the factors discussed above and following the recommended storage practices, you can ensure the longevity and optimal performance of your air compressor.

Quick Answers to Your FAQs

1. Can I store an air compressor on its side?

It is generally not recommended to store air compressors on their side, as this can lead to oil leakage and damage to internal components.

2. How often should I drain the air compressor tank?

Drain the tank daily or after every use to prevent moisture accumulation.

3. What is the proper oil for my air compressor?

Refer to the manufacturer’s recommendations for the specific type of oil required for your compressor.

4. Can I use compressed air to clean my compressor?

Yes, you can use compressed air to blow out dust and debris from the compressor’s exterior. However, avoid using compressed air to clean internal components.

5. How do I know if my air compressor is damaged?

Signs of damage include leaks, excessive noise, reduced air pressure, and overheating. If you suspect damage, contact a qualified technician.
