60 kHz31 µm1.2 mL/s
120 kHz12–15 µm0.4 mL/s

No lower flow limit. Wetted materials: titanium, stainless steel, PTFE. Droplet size is independent of flow rate and pressure. Sizes are measured near the nozzle tip; droplets shrink in flight, so the size at your substrate depends on standoff distance and solvent.

Key Characteristics

  • Zero air, zero fluid compression — purely acoustic atomization
  • Low-velocity spray (~1 m/s) for material-efficient coating
  • Self-cleaning, non-clogging titanium construction
  • Best with low-viscosity liquids (below 50 cP, ideally below 20 cP)
  • Vacuum and pressure compatible
  • Driven by 20 W broadband generator, 25–120 kHz tracking range
