The spray angle selected for a specific application depends on the size of the area to be sprayed. Since the fluid droplets immediately after exiting the nozzle are influenced by external factors, such as gravitation, gas flows, etc., the spray angle is measured in order to determine the spray coverage as a function of the application at a distance of 100 to 1000 mm. We are happy to perform individual spray tests in our highly specialized spray laboratory by appointment. The following diagram shows the theoretical spray coverage (E) at a distance (D) as a function of the spray angle (A). The effective spray angle (C) is smaller than the theoretical angle (E) and can be calculated from the actual spray coverage (B).
