The 1/8 NPT external-mix spray nozzles atomize fluids up to 25 gal/hr, and they can be used on liquids with a viscosity up to 800 cP. Suited for uses where a high volume of liquid is needed, the nozzles combine liquid and compressed air to create an adjustable coating of liquid. When used with water or coolant, the atomizing nozzles are an efficient way to evenly cool hot items in automated processes. Because they are external mix, airflow and liquid flow can be controlled independently to provide precise liquid flow. The nozzles also are offered in 1/4 and 1/2 NPT.
