Siphon fed nozzles are a great alternative for spraying where no liquid pressure is available. EXAIR has 3 sizes from 1/8 NPT, 1/4 NPT and 1/2 NPT nozzles along with “No-Drip” nozzles in the same sizes. Siphon fed nozzles require no liquid pressure and can be used with gravity fed liquids or lift liquids from a siphon height as much as 36′ (91 cm). Siphon fed nozzles work best with thinner liquids up to 200 centipoise.
EXAIR Air Atomizing Nozzles are manufactured from 303 stainless steel for durability and corrosion resistance. The siphon fed nozzles can be easily implemented where a tank can be installed and lower the cost of the installation by not requiring a liquid pump, just point of use compressed air.
In addition to the sizes and no drip option the siphon fed nozzle comes in two spray patters. The round pattern offers more liquid pass through and can be used in cleaning, rinsing, cooling and coating applications.
The siphon fed flat fan pattern nozzles are great where no liquid pressure is available and a thin coating is needed over a wide band. Flow rate is adjustable via the adjusting valve.
