Can You Safely Store An Air Compressor Outside? Here’s The Truth!

Air compressors are essential tools for various applications, from DIY projects to industrial tasks. However, ensuring their longevity and optimal performance requires proper storage. One common question that arises is whether an air compressor can be stored outside. This blog post delves into this topic, exploring the factors to consider, potential risks, and best practices for outdoor storage.

Factors to Consider

Before storing an air compressor outside, it’s crucial to assess the following factors:

• Climate: Extreme temperatures, humidity, and precipitation can significantly impact the compressor’s components.
• Usage frequency: If the compressor is used infrequently, outdoor storage may be acceptable with proper precautions.
• Compressor type: Oil-lubricated compressors require special attention due to their susceptibility to moisture.
• Protection measures: The availability of a covered area or storage unit to protect the compressor from the elements.

Potential Risks

Storing an air compressor outside without proper protection can lead to several risks:

• Corrosion: Moisture and condensation can corrode metal components, reducing their lifespan and performance.
• Electrical damage: Water ingress or excessive moisture can damage electrical connections and create safety hazards.
• Reduced efficiency: Cold temperatures can thicken oil, increasing friction and reducing the compressor’s efficiency.
• Component failure: Extreme weather conditions can cause seals, gaskets, and other components to deteriorate prematurely.

Best Practices for Outdoor Storage

If storing an air compressor outside is unavoidable, follow these best practices to minimize risks:

• Choose a covered area: Park the compressor under a roof, awning, or in a storage unit to protect it from rain, snow, and direct sunlight.
• Elevate the compressor: Place the compressor on a raised platform or blocks to prevent water damage from ground moisture.
• Drain moisture: Before storing, drain all water from the tank, lines, and filter to prevent freezing and corrosion.
• Lubricate moving parts: Apply a light coat of lubricant to moving parts to prevent rust and wear.
• Cover the compressor: Use a waterproof cover to protect the compressor from dust, debris, and moisture.
• Winterize the compressor: For cold climates, remove the oil and replace it with a suitable winter-grade oil.
• Regular maintenance: Inspect and maintain the compressor regularly to detect any signs of damage or deterioration.

Alternative Storage Options

If outdoor storage is not viable, consider the following alternative options:

• Indoor storage: A climate-controlled garage or workshop provides the ideal environment for storing an air compressor.
• Portable storage shed: A weatherproof shed can protect the compressor from the elements while allowing for easy access.
• Rental storage unit: A secure and temperature-controlled storage unit can be an option for long-term storage.

Final Note

Whether or not an air compressor can be stored outside depends on the specific climate, usage frequency, compressor type, and available protection measures. By carefully considering these factors and implementing the best practices outlined above, you can minimize the risks associated with outdoor storage and ensure the longevity and performance of your air compressor.

Quick Answers to Your FAQs

Q1. Can I store an oil-lubricated air compressor outside?
A1. Yes, but it requires special precautions such as draining moisture, applying lubricant, and winterizing the compressor for cold climates.

Q2. What is the ideal temperature range for storing an air compressor?
A2. Most air compressors operate best in temperatures between 40°F and 100°F (5°C to 38°C).

Q3. How often should I inspect an air compressor stored outside?
A3. Regularly inspect the compressor for signs of corrosion, moisture buildup, or damage, especially after prolonged exposure to harsh weather conditions.
