Mist or fog spray nozzles
The full cone or hollow cone pattern produced by many nozzles will break down into a fog/mist after a certain distance from the orifice. If a cone pattern is desired then this breakdown into a true mist is not desirable. But for some applications the breakdown of the spray into a true homogenous fog is the required result. As such, there are a number of nozzles that are designed to specifically produce this effect.
A mist pattern is characterised by having a low flow rate of very small droplet sizes with almost no impact. Typically this pattern will be used for evaporative cooling, moistening or humidifying applications.
There are three common designs of misting nozzle. Detailed information on the features and benefits of each design can be found by following the links in the blue menu box to the right hand side of this page.
All the information on all the various designs of misting nozzle is summarised in the misting nozzle cheat sheet which can be accessed by the orange tab to the right.
