Air-assisted Nozzle(Veljet nozzle)
The Veljet Atomizing Nozzle is designed for applicationsrequiring highly consistent and precise micro-coating. The nozzle is manufactured from 316 stainless steel and contains no internal moving parts or valves, ensuring stable long-term performance and minimal maintenance.
Unlike conventional air atomizing nozzles that rely solely on pressure and timing, the Veljet system delivers a precisely metered fluid stream into a controlled gas flow, forming a uniform atomized spray field through a precision orifice. This results in: Stable conical or beam spray patterns Excellent coating repeatability. Reduced material waste Compatibility with viscous fluids and suspensions. The Veljet nozzle is particularly effective for medical and pharmaceutical manufacturing, especially where validated and solvent-free processes are required.
