Product specifications

Structure • Comprising several parts : Nozzle body, adaptor, strainer, etc.
• First compressed air and liquid are mixed inside the nozzle for atomizing (Internal mixing type), then atomized droples are impinged against each other at optimum condition, which results in uniform distribution of droplet size.
• Liquid pressure type or Liquid siphon feed type.
