New External Mix Atomising Spray Nozzles

Louise Davis

Exair’s new 1/8 NPT No Drip External Mix Atomising Spray Nozzles mix liquid and air outside the nozzle and allow the air and liquid flows to be adjusted independently. The new, patented nozzles work in the same way the standard atomising nozzles do, but have the added benefit of positively stopping liquid flow when compressed air is shut off.

Post-spray drips waste precious resources such as expensive coatings, chemicals or water and are now eliminated. When spraying any type of liquid, post-spray liquid flow can cause big problems. Unwanted drips can ruin product function on sealing or mating surfaces. Drips can also ruin the appearance of painted or coated finishes. 

The nozzles are available in three different liquid patterns: round, narrow angle flat fan and wide angle flat fan patterns. They are available with 1/8, 1/4 and 1/2 NPT inlets with a variety of liquid flow values to suit the application. They are for pressure fed applications where precise liquid flow is needed. External mix nozzles can be used on liquids with a viscosity above 300 centipoise.

Applications include painting, coating, rinsing, cooling, quenching, wetting (moistening), dust control and humidification. The compact Atomising Nozzles are fully adjustable to minimise air and liquid consumption and have interchangeable liquid and air caps. They are CE compliant and conflict mineral-free. Prices start at US$332.
