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 and ruin the appearance of painted or coated finishes. In addition, excess liquid flow wastes precious resources such as expensive coatings, chemicals or water.

Now Exair has developed a novel half-inch no-drip internal-mix atomising spray nozzle that works in the same way as its standard atomising nozzles, but with the added benefit of positively stopping liquid flow when compressed air is shut off.

Internal-mix atomising spray nozzles mix liquid and air inside the nozzle and produce the finest atomisation of liquids up to 300cP. The patented no-drip design needs no additional airline.

Exair half-inch no-drip internal mix atomising nozzles are available in four patterns: narrow angle round, wide angle round, flat fan and 360° hollow circular pattern. They are for pressure-fed applications that don't require independent air and liquid control.

Available from Compressed Air Australia, the no-drip atomising nozzles are fully adjustable to minimise air and liquid consumption and have interchangeable liquid and air caps. Flow ranges from 0.5 to 1147L/h. They are also available in quarter- and eighth-inch sizes, and are CE compliant and conflict mineral free.
