The .006" YELLOW o-ring is the smallest standard nozzle orifice available. At 1,000 PSI, the mean diameter of the droplets from this size orifice 12.2 microns with droplets ranging from 1.2 microns to 36.4 microns. The .006” nozzle is ideal for applications requiring extremely low flow with small droplet size and minimal moisture and is most commonly used for humidification. This nozzle is not designed to be used at pressure below 500 PSI.

The .008" RED o-ring At 1,000 PSI, the mean diameter of the droplets from this size orifice is 12.7 microns with droplets ranging from 1.4 microns to 37.9 microns. This size nozzle is ideal for applications requiring low flow with small droplet size and minimal moisture. It can be used for indoor humidification or outdoor cooling. This nozzle is not designed to be used at pressures below 250 PSI.

The .012" BLACK o-ring is the most common and can be used for most applications. At 1,000 PSI, the mean diameter of the droplets from this size orifice is 13.1 microns with droplets ranging from 1.6 microns to 39.1 microns. It provides comparable results to the .008" nozzle with an increased flow rate. It can be used both indoors and outdoors with complete evaporation.

The .016" BROWN o-ring is mostly used for outdoor applications where sufficient airflow and clearance allow for complete evaporation and where higher flows are required. At 1,000 PSI, the mean diameter of the droplets from this size orifice is 13.8 microns with droplets ranging from 3.8 microns to 47.9 microns.

The .020" GREEN o-ring is primarily used for outdoor applications requiring extreme flow with less need for complete evaporation. At 1,000 PSI, the mean diameter of the droplets from this size orifice is 15.2 microns with droplets ranging from 9.5 microns to 49.9.
