How to Remove Oil from an Air Compressor?

Published in Air Compressor Maintenance 2 mins read

To remove oil from an air compressor, you need to drain it using the drain plug and then refill it with new oil.

Here's a step-by-step guide on how to accomplish this:

Steps to Remove Oil from Your Air Compressor

  1. Locate the Drain Plug: Identify the drain plug on your air compressor. This is usually located at the bottom of the compressor tank.
  2. Prepare a Container: Place a suitable container beneath the drain plug to collect the used oil.
  3. Remove the Drain Plug: Using an adjustable wrench, carefully remove the drain plug. Be prepared for the oil to flow out.
    • Allow all the old oil to drain completely into the container.
  4. Replace the Drain Plug: Once the oil is fully drained, reinsert the drain plug. Tighten it securely using the adjustable wrench.
  5. Refill with New Oil: Slowly and carefully pour in new air compressor oil. You should use a high-quality oil specifically designed for air compressors, or the oil recommended by your compressor's manufacturer.

Key Considerations

  • Oil Type: Always use the correct type of oil specified for your air compressor model. Using the wrong oil can damage the compressor.
  • Oil Level: Refer to your compressor's manual to determine the correct amount of oil to add. Do not overfill or underfill the oil reservoir.
  • Safety: Always turn off the power to your air compressor and release all air pressure before attempting to drain or refill the oil. Wear gloves and eye protection to prevent contact with oil.
  • Disposal: Dispose of the used oil responsibly at an appropriate recycling or disposal center.

By following these steps, you can effectively remove the old oil from your air compressor and replace it with fresh, clean oil, ensuring it operates efficiently and has a long lifespan.
