Electrospray nozzles/Air-assisted Nozzle(Veljet nozzle)
Noanix designs and provides custom electrospray nozzles/Air-assisted nozzles for mainly low flow rates applications.
Noanix’s precision air nozzle delivers an accurate and controlled volume of fluid through a precision pump. The liquid injected into the airflow passes through a precision orifice, forming a uniform spray plume that is discharged in a consistent cone or beam pattern. In addition, the airflow exiting the nozzle further atomizes the sprayed droplets, enabling stable and consistent coating performance.
The Noanix Veljet nozzle is designed for applications requiring consistent and highly precise coating. Manufactured from 316 stainless steel, the Veljet nozzle contains no moving parts or valves that could interfere with spray performance. Unlike many air nozzles that rely on fluid pressure for atomization, the Veljet nozzle is supplied with fluid by a precision pump.
The precision pump delivers an exact volume of fluid to the nozzle, where it is injected into the airflow and passes through a precision orifice to form a controlled spray plume at the nozzle outlet. As a result, a uniform and repeatable cone or beam spray pattern is achieved.
The Veljet nozzle is capable of spraying not only viscous solutions but also suspensions containing fine particles.
It is particularly effective for syringe barrel and needle coating applications, offering an alternative that reduces the need for solvent-based silicone lubricants. The Veljet nozzle addresses the limitations of conventional solvent-based processes—such as evaporation, inconsistent coating thickness, and potential health hazards—and enables stable spraying of silicone with viscosities up to 100,000 cps at spray volumes of less than 1 mg.
