EXAIR’s atomizing spray nozzles are designed to create a fine mist of liquid through various spray patterns suitable for multiple applications. By combining liquid with compressed air, these nozzles allow for precise adjustments to the atomized liquid, ensuring they can effectively meet the specific requirements of your project. In this discussion, I will focus on the different spray pattern options available for our atomizing spray nozzles.
When selecting the appropriate spray pattern, it is essential to consider the intended function of the spray, whether for coating, rinsing, cooling, or increasing humidity. Additionally, understanding the geometry of the target or part is crucial, along with determining whether the part is stationary, in motion, or if the nozzle itself is moving. Once these factors are established, we can narrow down the options to one of the three primary spray patterns, leading to a more precise final selection.
Round patterns are utilized in both air and liquid atomizing systems. Air atomizers can operate with either siphon-fed or pressure-fed liquids and are categorized into narrow and wide angle configurations. While both types produce a full cone spray that expands in diameter, narrow-angle sprays tend to maintain a more concentrated pattern, making them ideal for applications such as rinsing, washing, or heavy coating. The distance from the target also plays a crucial role in determining whether a narrow or wide-angle nozzle is more appropriate for a given task.
Flat fan patterns are available in air atomizing spray nozzles, with options for both siphon-fed and pressure-fed systems. These nozzles come in various configurations, including narrow angle, wide angle, and deflected flat fan designs. The choice among these options depends on the specific target area that needs to be covered and the distance to that area. Flat fan nozzles are particularly effective for applying fine surface finish coatings, whether on moving components or when used with nozzles that operate around stationary objects.
The Hollow Cone pattern is offered in both liquid and air atomizing options. The liquid atomizing hollow stream nozzle is particularly effective for rinsing and washing components, as its hollow center allows for liquid conservation in areas where it is unnecessary. Meanwhile, the air-atomizing hollow cone nozzle, which can spray at a full 360°, is versatile enough for applications such as cleaning and coating the interiors of pipes, as well as for dust suppression across expansive areas.
