Multitasking has taken over the present workplaces, and tools that can multitask have become the new dominant factor. Thus there has been emerging a new trend of converting the existing air compressor as an air compressor pressure washer.
The pressure washer is a mechanical sprayer that uses high pressure to remove paint, grime mold, and other dirt from the surface and is often used for car washing. On the other hand, an air compressor transforms power into potential energy stowed in pressurized air; it is a pneumatic device, to be precise.
While decluttering the storeroom or the garage, we often have multiple items like holiday decorations, garden or car-related tools, and different basic stuff. Bundling up multiple items into a single one would always be a wise decision, and so is converting the air compressor into a pressure washer.
It saves space and money at the same time!
Can you convert an air compressor to a pressure washer?
The specific answer is yes, to an extent. But while converting the existing air compressor into a pressure washer, some extra attachments such as a spray gun and garden hose must be removed.
The “to an extent” refers to the pressure difference outcome. Most pressure washers come with a pressure output of between 750 psi (pound per square inch) to 3500 psi, and it can go up considering the model type.
With a standard garden hose, an air compressor can provide 40 to 50 psi pressure, and in extensive cases, it can go by 100 to 200 psi but not more than that.
However, these two items have similarities regarding the functional parts. The air compressor has a direct drive motor, an engine, an air tank, and an air pump. And the power washer has an engine, electrical power system, nozzles, valves, and spray gun. In both the machine, the pressure outcome can be regulated as per the need.

How to use pressure washer attachment for air compressors: Step by Step Guide
A conventional nozzle or spray gun cannot provide water pressure compared to traditional pressure washers (not even the one with the least quality). Thus we have picked the above-reviewed attachments that will multiply the pressure of the air compressor. The combination unit will ensure maximum water pressure.
- An air compressor
- A faucet outside the house for enough water supply
- A spray gun with two inlet facilities (M MINGLE/ Guardair Pneumatic/ Turbo Jet)
- A standard garden hose
The Step by Step Process
- First of all, check the gauge so that the air compressor has at least 30 psi pressure. Less than 30 psi Pressure won’t provide enough water flow.
- After that, connect one side of the standard garden hose to any spray gun and the other side to the outside faucet.
Note: For M MINGLE spray gun, if the garden hose has 14 mm inside diameter with M22 14 mm fittings, you can connect it to the garden hose directly. But you would need the brass coupler between the gun and the garden hose if the garden hose has 15 mm inside diameter with M22 15mm fittings. While using the Turbo Jet, you can connect it directly to any garden hose.
3. Now, attach the air hose to your preferred spray gun (M MINGLE/ Guardair Pneumatic/ Turbo Jet). Ensure it has sufficient air pressure.
Note: Attach the lower inlet of the spray gun to the garden hose and the upper inlet to the air hose.
4. Once you are done with all the connections, turn on the faucet and pull the spray gun’s trigger. If everything goes perfectly, you will see water coming out of the spray gun. To regulate the water pressure, adjust the gauge and spray gun’s trigger. And you are all set to enjoy your very own air compressor pressure washer.
What is a good PSI for a home pressure washer?
A home use applicable pressure means doing nothing aggressive rather than some modest furniture or surface cleaning. For example, 1300 to 2400 PSI (pound per square inch) is considered appropriate moderate cleaning yet is powerful enough against the toughest stains on vinyl, wood, or concrete surface.
Though pressure washing is extremely tempting as it claims the least manual effort to clean your home, you must be concerned about the psi while using power washers. Unnecessary high PSI can lead to damage to the wood and vinyl exteriors.
The same goes for the furniture. Again, even a pressure washing within 1900 psi is suggested to maintain the durability of the furniture.
How do you use a pressure washer air hose?
Air hose transports compressed air from the air compressor to other units. For example, the pressure washer air hose connects the attachments, such as spray gun nozzles, to the air compressor.
The compressed air passes pressure through the air hose, and the nozzles release high volume water. In short, a pressure air hose is a connecting element between the spray gun and the air compressor.
Is 100 psi enough for an air compressor?
For light to medium flow, 70 to 90 psi is excellent for an air compressor. But for heavy-duty flow, psi within 100 to 120 would be OK. Anyhow, 100 psi is quite a satisfactory rate for any medium to heavy-duty task. But, of course, there are also other factors that one must consider, such as CFM, the tank volume, and air fittings.
Bulky equipment like power washers tends to occupy garage space and storage areas, and no wonder none of us want so. So the idea of having multiple tools wrapped in one is quite a win to overcome storage struggles.
Though an air compressor pressure washer may not be as effective as the original pressure washer, the mentioned attachments in a combination unit with an air compressor can work wonders.
By Following the steps correctly and using the right pressure washer attachments, acquiring the same water pressure as an electric or gas pressure washer is not impossible any longer.
