pressure washer nozzle size guide
Pressure washer nozzles are essential for optimizing cleaning tasks by adjusting water flow and pressure. They come in various sizes and spray angles, impacting performance. This guide helps you understand nozzle sizes, types, and how to choose the right one for your needs.
Understanding Nozzle Sizes
Nozzle sizes impact performance by regulating water flow and pressure; Smaller orifices increase pressure but restrict flow, while larger ones allow more flow but reduce intensity. Proper sizing ensures efficiency and safety, matching your pressure washer’s GPM and PSI specifications effectively.
Orifice Size Explained
The orifice size of a pressure washer nozzle is the diameter of the small opening through which water flows. Measured in inches, it determines the flow rate and pressure output. A smaller orifice restricts water flow, increasing pressure, while a larger orifice allows more water to pass through, reducing pressure. Proper orifice sizing is critical for optimizing cleaning efficiency and preventing damage to surfaces. The orifice size must align with the pressure washer’s gallons per minute (GPM) and pounds per square inch (PSI) ratings. For example, a smaller orifice (e.g., 0.020 inches) is ideal for high-pressure tasks like concrete cleaning, while a larger orifice (e.g., 0.040 inches) is better for low-pressure jobs like washing vehicles. Using the wrong size can lead to insufficient cleaning power or excessive wear on the equipment. Always refer to the manufacturer’s guidelines to select the correct orifice size for your specific needs.
Spray Angles and Their Uses
Spray Angles and Their Uses
Spray angles are a critical factor in determining the effectiveness of a pressure washer nozzle. They refer to the width of the fan-shaped water stream produced by the nozzle. Common spray angles range from 0° (a narrow, concentrated jet) to 65° (a wide, dispersed spray). Each angle serves specific purposes, making it essential to choose the right one for the job. A narrower angle, such as 15° or 25°, is ideal for heavy-duty cleaning tasks like stripping paint or cleaning concrete, as it delivers high pressure over a small area.
