Product specifications

Structure • Comprising several parts : Nozzle body, adaptor, strainer, etc.
• First compressed air and liquid are mixed outside the nozzle for atomizing (External mixing type), then atomized droples are impinged against each other at optimum condition, which results in uniform distribution of droplet size.
• Liquid pressure type.
Material • Nozzle Body: S316 equivalent
• O-ring: S321
• Others: S316
