Can Air Compressor Double as Pressure Washer?

Have you ever wondered if you can use an air compressor as a pressure washer? In this article, we will explore the feasibility of converting an air compressor into a pressure washer and its potential as an alternative to traditional pressure washers.

When it comes to cleaning tasks that require high pressure, such as removing stubborn dirt, grime, or stains, a pressure washer is often the go-to tool. However, not everyone may have access to a pressure washer or may be looking for a more cost-effective solution.

So, is it possible to repurpose an air compressor to serve as a pressure washer? Let's find out!

Before we dive into the details, it's important to note that converting an air compressor into a pressure washer requires proper modifications and additional equipment. While it may be tempting to experiment with DIY solutions, it's crucial to adhere to safety precautions and guidelines to ensure efficient and safe operation.

Can Air Compressor Double as Pressure Washer?

Key Takeaways:

  • Converting an air compressor into a pressure washer is technically possible.
  • It requires proper modifications and additional equipment.
  • An air compressor can serve as an alternative for light cleaning tasks.
  • However, it may not be as powerful or efficient as dedicated pressure washers.
  • Safety considerations and limitations should be carefully evaluated before attempting the conversion.

Using an Air Compressor for High-Pressure Cleaning

When it comes to high-pressure cleaning tasks, an air compressor can be a valuable tool in your arsenal. While it may not offer the same power and efficiency as a dedicated pressure washer, it can still be an effective alternative for certain cleaning applications.

To use an air compressor as a pressure washer, you will need to equip it with the necessary accessories and make a few modifications. The key components include a pressure washer gun, a nozzle, and a high-pressure hose that can withstand the air compressor's output.

Equipment and Accessories

  • A pressure washer gun: This handheld device allows you to control the spray pattern and force.
  • A nozzle: Choose a suitable nozzle size for your cleaning requirements, as it determines the spray angle and intensity.
  • A high-pressure hose: Ensure that the hose is rated for the air compressor's pressure output to prevent any damage.

In addition to these essentials, you may also need to consider using a water filter to remove any contaminants that could clog the nozzle or malfunction the equipment.

Limits and Considerations

It's important to note that using an air compressor as a pressure washer does come with certain limitations. The air compressor's output pressure may not be as high as that of a traditional pressure washer, resulting in reduced cleaning power. Additionally, the flow rate may also be lower, leading to slower cleaning times.

Furthermore, air compressors are primarily designed for pneumatic tools and may not have the necessary safety mechanisms or features specific to pressure washing equipment. Therefore, caution must be exercised while using an air compressor for high-pressure cleaning tasks.

Overall, if you have a suitable air compressor and are willing to make the necessary modifications and considerations, it can be a viable option for light to moderate cleaning tasks. However, for heavy-duty or commercial cleaning applications, investing in a dedicated pressure washer is recommended for optimum performance and safety.

Converting an Air Compressor into a Pressure Washer

In this section, we will guide you through the process of converting an air compressor into a pressure washer. By following these step-by-step instructions, you can repurpose your air compressor to perform cleaning tasks typically handled by a pressure washer. This conversion can be a cost-effective solution, especially if you already own an air compressor.

Gather the Essential Components

Before starting the conversion, ensure you have the necessary components. Here's a list of items you'll need:

  • High-pressure hose: The hose will deliver the pressurized water from the air compressor to the cleaning nozzle.
  • Pressure washer gun and wand: These handheld accessories help control the water flow and direct it to the desired cleaning area.
  • Nozzle tips: Different nozzle tips allow you to adjust the spray pattern and intensity, catering to various cleaning tasks.
  • Safety goggles and gloves: Protecting your eyes and hands is crucial when working with a pressure washer or modified air compressor.

Make the Necessary Modifications

To convert your air compressor into a pressure washer, you'll need to make a few modifications. Here's what you should do:

  1. Attach the high-pressure hose to the air compressor's outlet valve, ensuring a secure connection.
  2. Connect the pressure washer gun and wand to the other end of the high-pressure hose.
  3. Select the appropriate nozzle tip for your cleaning needs and attach it to the pressure washer gun.
  4. Check for any leaks or loose connections, ensuring a safe and reliable setup.

Operate the Converted Air Compressor

Now that your air compressor is converted into a pressure washer, it's important to follow these safety precautions:

  1. Always wear safety goggles and gloves while operating the converted air compressor.
  2. Start the air compressor and allow it to build up pressure.
  3. Hold the pressure washer gun securely and point it away from yourself and others.
  4. Begin cleaning by pulling the trigger on the pressure washer gun, controlling the water flow.
  5. Move the wand back and forth to cover the desired cleaning area evenly.
  6. Keep a safe distance from delicate surfaces to avoid damage from the high-pressure water.
Advantages Disadvantages
- Cost-effective alternative to purchasing a dedicated pressure washer - Limited power and pressure compared to professional pressure washers
- Utilizes an existing air compressor, saving money and storage space - Requires modifications and additional components
- Can effectively handle light cleaning tasks - May not be suitable for heavier-duty or commercial cleaning projects
Can Air Compressor Double as Pressure Washer?


In conclusion, while it is technically possible to use an air compressor as a pressure washer, it requires proper modifications and additional equipment. It can serve as an alternative for light cleaning tasks, but may not be as powerful or efficient as dedicated pressure washers. However, it's important to consider the limitations and safety considerations before attempting to convert an air compressor for high-pressure cleaning purposes.

Firstly, converting an air compressor into a pressure washer requires careful modification of the equipment to ensure it can handle the high-pressure water flow. Specialized attachments and fittings may also be necessary to connect the air compressor to a water source and dispense the water effectively.

Secondly, while an air compressor can provide sufficient pressure for light cleaning tasks such as washing cars or small outdoor surfaces, it may lack the power and flow rate of a dedicated pressure washer. For heavy-duty cleaning or large-scale projects, a traditional pressure washer is undoubtedly the more efficient choice.

Lastly, safety must be a top priority when using an air compressor as a pressure washer. It's crucial to follow the manufacturer's guidelines for modifying the equipment and ensure proper ventilation to prevent any potential risks. Additionally, never use an air compressor near electrical sources or in wet conditions to avoid accidents.
