Exair’s new 1/2 NPT no drip internal mix atomising spray nozzles work in the same way its standard atomising nozzles do, but have the added benefit of positively stopping liquid flow when compressed air is shut off. They mix liquid and air inside the nozzle and produce atomisation of liquids up to 300 centipoise. The patented ‘No Drip’ design requires no additional air line to control the No Drip feature.
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. No Drip atomising nozzles are signed for where no post-spray drip is permissible. When the compressed air supply is shut off, the nozzle positively seals off the flow of liquid eliminating the possibility of drips.
The nozzles are available in four patterns: narrow angle round, wide angle round, flat fan and 360 degree hollow circular pattern. They are for pressure-fed applications that don't require independent air and liquid control.
They are fully adjustable to minimise air and liquid consumption and have interchangeable liquid and air caps. Flow ranges from 0.14 Gph to 303 Gph (0.5 Lph to 1147 Lph). They are also available in 1/8 NPT and 1/4 NPT, and are CE compliant and conflict-mineral free. Prices start at US$295.
