    Can an air compressor be made pressurized?
    If you can with compressed air and sand, you can sandblast. With compressed air and water, am I able to make a pressure washer?

    I don't have a compressor and ejector.

    And what do you mean by "karcher"?

    The air compressor will suck in the water and spit it out under pressure, but only once. On the next attempt, rusty water will flow in a few hours and the piston and sleeve will need to be replaced. Each time it would require disassembling the whole and wiping the elements dry. In addition, the piston is lubricated with oil, which is then separated. There are also dry compressors, but this does not mean that it will withstand water. Sandblasting, however, is a different story. There, the compressor does not pump the sand, but it is fed through a separate duct to the compressed air outlet, which gives the shot a large momentum.

    Do you know how sandblasting works? Sounds like sand is being sucked into the engine :) . Do you know what an ejector is?

    I will refresh :) I have an oil tank from a compressor with a damaged tank, after connecting constant water, would it somehow give a stream of water? and what valve would have to be used to prevent water from entering the compressor?

    Why bother? There are ready-made solutions on the market.


    Pneumatic cleaning gun HCL-43

    Or other pneumatic wash guns simply connect water

    The Karcher on average gives around 100 bar, and the compressor a little less. I wouldn't expect a super effect.

    As to the subject, the working medium in the washer is water. A water pump is therefore needed.
    A compressor could be used to make a washer along the lines of a paint gun or sandblasting gun - feeding water into the air stream. However, the efficiency of such a solution will be significantly lower than that of a typical washer.
    However, with the cost of a washer in the order of 200-300 PLN, converting an equally expensive or even more expensive compressor, perhaps still under the supervision of the Office of Technical Inspection, into a pseudo-washer, the sense of such a solution is highly questionable.

    I let go as soon as I wrote the post:) I found a Karcher ProHD 600 in a scrap container with damaged wheels, cable and a bit of plastic at a repair cost of £0.

Topic summary

The discussion centers on the feasibility of using an air compressor as a pressure washer. While some participants suggest that it is possible to create a makeshift pressure washer using a compressor and a venturi tube to mix water with compressed air, they caution that the efficiency will be significantly lower than that of a dedicated pressure washer. Concerns are raised about the potential damage to the compressor from water ingress and the need for proper valves to prevent water from entering the compressor. Comparisons are made to commercial solutions, such as pneumatic cleaning guns, and specific models like the Karcher ProHD 600 are mentioned as more effective alternatives.
