New no-drip nozzles stop liquid flow

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. In addition, excess liquid flow wastes precious resources such as expensive coatings, chemicals or water. 

Exair has the solution. Its new no-drip siphon-fed atomizing spray nozzles are ideal where no post-spray drip is permissible. When the compressed air supply is shut off, the no-drip nozzle positively seals off the flow of liquid, eliminating the possibility of drips. 

The no-drip nozzles require no liquid pressure and can be used with gravity-fed liquids or lift liquids from a siphon height as much as 36 inches (91 cm). Siphon-fed nozzles can be used on liquids up to 200 centipoise. 

The new nozzles work in the same way Exair’s standard atomizing nozzles do, but have the added benefit of positively stopping liquid flow when compressed air is shut off. 

They are available in a round pattern and a flat fan pattern, and are ideal for non-pressurized liquid applications that don't require independent air and liquid control.

Applications include painting, coating, rinsing, cooling, quenching, wetting (moistening), humidification and dust control. The compact atomizing nozzles feature a patent-pending no-drip mechanism and have interchangeable liquid and air caps. They are CE-compliant and conflict mineral-free.
