1/8 FNPT, 1/4 FNPT and 1/2 FNPT siphon fed round pattern nozzles are great where no liquid pressure is available and a thin coating is needed at a specific area. Flow rate is adjustable via the adjusting valve. Siphon nozzles work best with a suction height of 36" (914mm) or less. Since these nozzles are siphon fed, the compressed airflow draws the liquid in and mixes it internally. Liquid flow is dependent both on the gravity or suction height and the airflow. Siphon fed round pattern nozzles provide the most liquid flow of any siphon fed nozzle. No drip models also available to preserve precious liquids and protect product finished from drips.Made from 303SS for corrosion resistance.Siphon or gravity fed for non-pressurized applications.
