No Drip Atomizing Spray Nozzles: Overview

Are you tired of your dripping nozzle leaving puddles on your equipment and making a mess? Do the liquids you use to treat or coat your materials cost you a great deal of money? EXAIR’s No Drip Atomizing Spray Nozzles have been engineered eliminate drips; these patented nozzles contain a spring mechanism that when the air pressure reaches above 30 psig the valve will open allowing the liquid to escape out.

EXAIR No Drip Air Atomizing Spray Nozzles come in three styles. Internal mix, External mix and Siphon fed. 

One of the most commonly used types of No Drip Atomizing Spray Nozzles is the Internal Mix. The Internal Mix nozzle mixes the liquid and the air inside the cap and produces the finest droplet size out of the three. Due to the fact that the liquid and air are mixed in the cap, Internal Mix nozzles are used on liquids that have a lower viscosity (less than 300 cP). This means that they are usually used on liquids such as water, water soluble/diluted lubricants, lightweight oils, or rust inhibitors.

External Mix No Drip Atomizing nozzles have the highest flow rates and allow the air and liquid flows to be adjusted independently. These are best when precise liquid flow is needed. External mix nozzles can be used when the liquid viscosity is above 300 cP. 

Siphon Fed No Drip Atomizing nozzles require no liquid pressure and can be use dwith gravity fed liquids or siphon liquid from a height as much as 36 in. (91cm). These can be used with liquids up to 200 cP. 

No Drip Atomizing Nozzle
The No Drip Atomizing Spray Nozzles share the same spray patterns as our line of standard atomizing spray nozzles. This means that they are available in Narrow Angle Round Pattern, Wide Angle Round Pattern, Flat Fan Pattern, Deflected Flat Fan Pattern and 360° Hollow Cone Pattern. Along with the five different spray patterns they also come in three different inlet sizes of 1/8″, 1/4″ and 1/2″ NPT.
No Drip Flat Fan Spray Nozzle
Each NPT size also comes in a variety of different sizes in the corresponding spray volume. For example, the 1/8” No Drip Internal Mix Flat Fan Nozzles have for different Nozzles with a flow rate ranging from 3.47 GPH to 28 GPH (13.2 LPH to 105.99 LPH). This gives the No Drip Internal Mix Atomizing Nozzle 36 different variations to fit your application.

Step by Step Guide – Choosing Atomizing Spray Nozzles

EB1040SS

Atomizing spray nozzles atomize fluids to create a fine spray in a variety of patterns for a variety of uses. They are commonly used to mark products, paint or coat, cool, reduce dust, lubricate and clean parts.

With the numerous types of Atomizing Nozzles sold by EXAIR, it can be challenging to shift through all the information. We can help you to narrow down the field to quickly find the correct Atomizing Nozzle for your application.  In a summary, here are the basic questions that need to be answered:

1.) Are you using a pressurized liquid feed?

2.) What is the viscosity of the fluid?

3.) What is the liquid feed rate in gallons per hour (gph) or liters per hour (lph).

4.)  Should I use the No-Drip option?

EXAIR’s flow chart with easy-to-follow steps will walk you through the decision tree and land you at the best Atomizing Spray Nozzle for your application. In answering these simple questions, this chart will guide you to the correct page in our current catalog to get additional information and specifications.    Click on Link below to determine the best nozzle for you.

Introducing….Our Continued Commitment to New Products

There’s a lot of flutter this week about the Consumer Electronics Show going on and all the latest gadgets.  I’ve seen numerous Twitter posts and feeds updating those of us not present in Las Vegas about all the latest creations from top electronics producers, and the products are quite inviting.  (Something that has stood out to me amongst these posts is the presence of celebrities and some of their aggressive Twitter campaigns to launch products.)

With all this discussion about new products, I thought it’d be a shame not to mention a few of ours.  For anyone who uses EXAIR products, our Atomizing Nozzles have quickly become a familiar product.  With the diligent work of Professor Penurious and the rest of the staff at EXAIR, we’ve positioned ourselves to launch even more Atomizing Nozzles!  We have an external mix line of nozzles, and a siphon fed nozzle line that have recently been added, look for their official debut soon.

Application photos and full web pages are in the works, but you fellow blog readers have the inside track on product availability!  If you have a potential need for a liquid spray nozzle, give us a call.  We’d love to work through the application with you.

And what celebrity should we get to plug our new stuff from their Twitter account?
