A Brief Note on Pressure Washers
Pressure Washer is a very useful power tool that makes cleaning job very easy. It produces a high-pressure water spray to clean different kinds of surfaces and objects. They are available as gasoline engine powered or electric motor powered. Apart from the engine/motor, there is a spray gun with a trigger and a nozzle at the end. The engine or motor will drive a pump to increase the incoming water pressure by several hundred times. Nozzle at the end of the spray gun directs this high-pressure spray on the surface. The nozzle also can have a specific angle of the spray i.e., a wider spray to cover large area with slightly distributed pressure or a more focused spray with maximum pressure at the point of impact. So, it is clear that the nozzle of a pressure washer is a very important part in the overall working. With a proper nozzle size, you can the correct pressure, spray pattern and distance.
Pressure Washer Nozzle Chart
Before looking at the pressure washer nozzle chart, an important point about pressure washers in general is that we measure its cleaning power in terms of Gallons per Minute or GPM. Higher the GPM, more water flow rate and faster it can clean. Apart from GPM, the pressure at the nozzle, which is measured in pounds per square inch or PPI is also important. For regular household cleaning, we need a pressure washer that can produce roughly about 2,500 to 3,000 PSI with a flow rate of 2.5 to 3 GPM. Coming to pressure washer nozzle sizes, we use the combination of GPM and PSI to determine the size i.e., a nozzle must handle pressure washer GPM at a particular PSI. With this information in mind, let us proceed with the pressure washer nozzle chart for different GPMs and different PSI values.
How to Choose the Right Size Nozzle?
As the nozzle determines the spray pattern, pressure, angle and also the intensity, choosing the right nozzle size is very important. If you select a smaller nozzle size than what is required, then you may damage the pressure washer due to the additional pressure. On the contrary, if you select a larger nozzle size, then you will compromise the cleaning ability by reducing the pressure. So, it is important that follow some guidelines set by the manufacturer to select the correct pressure washer nozzle. Most pressure washer manufacturers provide a recommended list of nozzle sizes for a particular machine depending on its GPM and PSI values. In case you don’t have that information, the you can use the previous pressure washer nozzle chart to figure out the appropriate nozzle size.
Pressure Washer Nozzle Color Code
You can easily identify the angle of the spray from a nozzle just be looking at its color. Here is the list of some standard nozzle colors that most manufacturers use for different spray angle nozzles. Using the above table as reference, you can easily select a nozzle for different spray angles.
Conclusion
Pressure Washer Nozzles have very little attention but they are an important part of the entire machine. Using a correct nozzle size will not only make the cleaning job easy but also prevents damage to your expensive pressure washer unit. In this guide, we saw some common pressure washer nozzle sizes in a simple pressure washer nozzle chart. We also saw the nozzle colors for different spray angles. Comment * Name * Email * Website
