FullStream Liquid Atomizing Nozzles

At EXAIR, we know compressed air, and we’ve been helping customers around the world get the most out of their compressed air systems since 1983. It was only logical that, about ten years ago, we got into using compressed air for liquid atomization.  If you’re looking to spray a liquid in a fine mist with a controllable pattern & flow rate, there are many advantages to using compressed air to atomize it:

  • Adjustability
  • Maximum dispersion
  • Optimal, efficient consumption
  • Small droplet size

Since their introduction, EXAIR has come to offer 142 distinct models of Air Atomizing Spray Nozzles, and, along the way, we leveraged our engineering, machining, and manufacturing prowess to gain position as an industry leader in liquid spraying.  So much so, that, earlier this year, we introduced a spraying product line that doesn’t require compressed air:  the FullStream Cone Liquid Atomizing Nozzles.  Instead of using the energy of compressed air to effect atomization, these use the energy of the liquid’s pressure and flow to change the continuous stream of liquid flow entering the nozzle into a conical spray as it exits to atmospheric pressure.  Here’s how it works:

While Air Atomizing Spray Nozzles maintain their advantage of a smaller droplet size (ours consistently make droplets under 100 microns in size,) there are clear benefits in certain applications to the FullStream Cone Liquid Atomizing Nozzles:

  • Higher liquid flow rates
  • Increased liquid coverage
  • More compact design

These are all important in applications like quenching, cooling, foam breaking, lubricating, degreasing, and sanitizing.  All stainless steel construction means they’ll stand up to a variety of chemicals…both in what’s being sprayed, and in the environment in which they’re installed.

If you have a liquid that needs sprayed, EXAIR has an engineered solution.  Call an EXAIR Application Engineer today to find out more.

EXAIR NEW Product Offering – Full Stream Cone Liquid Atomizing Nozzles

EXAIR has continued to build on a large catalog of Intelligent Compressed Air Products. In catalog 27 we introduced our Atomizing Nozzles ! I’m happy to announce we have added a new line of FULLSTREAM LIQUID ATOMIZING NOZZLES! , they do not use compressed air. The current Full stream nozzles available are our FullStream Cone Liquid Atomizing Nozzles with a 1/4 NPT port.

EXAIRS new FullStream Cone Liquid Atomizing Nozzle

EXAIR’s FullStream Cone Nozzles, have a full cone spray pattern, are among the most common type of spray nozzles. Full cone spray nozzles are applied to solve cooling, cleaning, washing, rinsing and dust suppression applications throughout industry. Their design is vaneless, which creates wide open internal features to resist clogging and can work well with liquids containing particulate. They produce a uniform distribution in a full cone round pattern. Their right-angle design is compact and operates up to 250 PSIG liquid pressure. They are commonly used with liquids like water, rinse aids or detergents but are also effective with chemicals, pesticides and herbicides. Adjustment of the liquid flow rate is done by varying liquid pressure. FL1010SS @ 2.36 GPH & 60 PSI

Bellow you will see a video of the FullStream Cone Liquid Atomizing Nozzle, FL1010SS,  2.36 GPH @ 60 PSI.

EXAIR Atomizing Spray Nozzles for Coating, Cleaning, Cooling

A recent customer in the automation / tool making industry had a need to spray a mold release agent onto some specialized tooling. Originally, the customer had planned to use some sort of pressurized sprayer. After some initial tests to prove the concept, the customer found that the moving mechanical parts of the sprayer became fouled by the release agent. And cleaning the internal parts was not easy to do.

In their search for a more permanent solution, the customer came across EXAIR Atomizing Nozzles. After going through some application type questions to narrow the focus down to one model, we determined that the customer would be best served by model AF1010SS (Internal Mix, Flat Fan Pattern Atomizing Nozzle). The customer had a couple of questions about the nozzle in order test the product.

  1. Is it possible to disassemble the nozzle and clean it completely? The answer is yes, the Atomizing Nozzles can be completely disassembled to allow for cleaning, maintenance or replacement of worn parts.
  2. Are the nozzles solvent resistant? The answer is also yes; the Atomizing Nozzles are made of AISI303 type stainless steel and can be cleaned with any normal solvent based cleaner.

Earlier in this article, I mentioned that we went through some application type questions. Here is a list of general questions that we normally ask a customer about their application in order to determine which in our selection would be best suited.

  1. What is the volume of liquid flow (G/Hr) needed for the application?
  2. What is the viscosity (cP) of the liquid being applied?
  3. What are the required spray pattern, size and shape required?
  4. Is the liquid under pressure (by pump or pressure pot)? If so, what is the liquid pressure?
    1. Side note: we have options for non-pressurized liquid by using our siphon fed nozzles.

If you have an application where you have a liquid that needs to be applied in atomized form to a target, or perhaps a humidification application, please give EXAIR Atomizing Nozzles your consideration.

Siphon Fed No-Drip Atomizing Spray Nozzles

With 142 distinct models in stock, the Atomizing Spray Nozzles are easily EXAIR Corporation’s most diverse product line. If you need a reliable method of creating a fine mist of liquid flow with a flow rate as high as 303 gallons per hour (or as low as 0.1 gallons per hour,) with a spray pattern as large as 13 feet (or as small as 2-1/2 inches) in diameter, look no further – we have a spray nozzle for you, on the shelf and ready to go.

Siphon Fed models are the subject of today’s blog – they don’t require that the liquid be under pressure; you can feed them from the vessel the liquid comes in from a siphon height of up to 36 inches, or, for higher flows, from a gravity height of as low as 6 inches.

EXAIR Siphon Fed Nozzles work with non-pressurized liquids, either siphoned (left) or gravity fed (right.)

All Atomizing Spray Nozzles are available with EXAIR’s patented No-Drip option, which positively shuts off liquid flow when the compressed air supply is shut off.  One benefit of this is realized in coating applications, where an errant droplet of liquid would mar an otherwise smooth, even coating.  Operationally, though, it also means you can precisely turn the liquid flow on & off, in short, quick bursts, up to 180 times a second.

By far, the simplest way to do this is with a valve installed in the air supply line to the Atomizing Spray Nozzle.  A manual 1/4 turn ball valve works fine if you want the operator to control it.  Solenoid valves are often used to automate the process, and if you’ve got something to open & close the valve, you’re all set.  For example, if you want to spray coolant onto a cutting tool, just wire the solenoid valve into the on-off switch of the machine, like in the example shown to the right.

Alternately, our EFC Electronic Flow Control System provides a ready-to-go solution.  It comes pre-wired; all you have to do is plumb the valve into the air supply line and plug it in to a 120VAC grounded wall outlet.  When the photoelectric sensor “sees” the part you want to spray, it opens the valve.  When the part passes, it shuts the valve.  Easy as that.

I like this whole video, but if you just want to see the EFC Electronic Flow Control & Atomizing Spray Nozzle in action, skip to the 4:05 mark.

If you have a need to spray a fine, controllable liquid mist, EXAIR has a wide range of solutions.  Give me a call.
