Siphon Fed Atomizing Nozzles Selection

If you follow along with our blog, you will notice that we have recently published a few entries relating to our Atomizing Nozzles. Today, I would like to continue this trend and focus on our Siphon Fed Atomizing Nozzles.

When recommending an Atomizing Nozzle for a particular process, we try to obtain as much “general” information as possible about the application, such as:

  • What type of spray pattern do you need?
  • How wide of an area needs to be covered?
  • What kind of flow rate needs to be achieved?
  • Is the liquid source pressurized?
  • What is the viscosity of the liquid?

While all of this information is going to help simplify the selection process, when we get a reply that the liquid isn’t pressurized, the choice becomes a little less complicated.

Our Siphon Fed Atomizing Nozzles are the preferred solution in applications where a pressurized liquid source isn’t available. With a steady supply of compressed air, these nozzles are able to draw the liquid into the nozzle with suction heights up to 36″ for our 1/8″ NPT and 1/4″ NPT nozzles, and up to 24″ for our larger 1/2″ NPT Models. They can also be gravity fed as well.

1/8″, 1/4″ and 1/2″ FNPT Sizes Available

These nozzles mix the fluid internally and are capable of handling viscosity up to 200 centipoise. Depending on the size of the nozzle and supply air pressure, flow rates can range from 0.4 GPH up to 60 GPH with either a round or flat fan spray pattern. There is also an adjusting valve for more or less liquid flow as needed to fit the demand of the application.

We also offer these nozzles with our patented No Drip feature which positively stops the liquid flow when the supply air pressure drops below 30 PSIG, eliminating the need for any additional valves or supply lines.

1/2″ NPT No Drip Model # SR6010SS

If you have an application requiring a fine mist of atomized liquid, give me a call at 800-903-9247.
