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.
Post spray drips waste precious resources such as expensive coatings, chemicals or water and are now eliminated with Exair’s patented design. 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. Exair’s no drip atomizing 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.
Exair 's no drip external mix atomizing nozzles are available in three different liquid patterns: round, narrow angle flat fan and wide angle flat fan patterns. No drip external mix atomizing nozzles are available with 1/8, ¼, and 1/2 NPT inlets with a variety of liquid flow values to suit your 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 atomizing nozzles are fully adjustable to minimize air and liquid consumption and have interchangeable liquid and air caps. They are CE compliant and conflict mineral free. Prices start at $332.
