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.

What Makes EXAIR’s Super Air Knife so Efficient

EXAIR Super Air Knives have been designed to improve upon performance characteristics of our original Standard Air Knife design, which was already a very good performer itself. The Super Air Knife design improves air consumption and noise exposure levels. Since they use less air, they cost less to operate. Because they operate quieter, they can contribute to a quieter environment and increase safety for your personnel. 

Compressed air is such a common utility in manufacturing environments (and more) that many of us take it for granted and may not be the best stewards of its use.  EXAIR Super Air Knives are the most efficient compressed air knife on the market today and help us all to use our compressed air more wisely.

If you have homemade air knives, pipe with drilled holes or manifolds with multiple nozzles, you are in a position to play the hero and save your company compressed air and money. 

Implementing a design which uses the free air surrounding us all, is a significant feature making the Super Air Knife efficient. This is done by utilizing entrainment to move the surrounding ambient air and amplify the blast of compressed air.

Diagram showing how the Super Air Knife works

Air Entrainment is the phenomenon that occurs when air/gas under pressure is released from a device in such a way that a low pressure is generated in the immediate area of the gas discharge.  Gas from the surrounding environment is then pulled into the discharged air stream, increasing its volumetric flow rate. Using this principle, a Super Air Knife increases the air flow without increasing the amount of compressed air used.

This phenomenon is prevalent in many of EXAIR’s products but shines the brightest with EXAIR’s Super Air Knife. The Super Air Knife Sports the highest entrainment ratio out of all of the products with a whopping 40:1 ratio, this makes for a very efficient use of compressed air. With an air consumption of only 2.9 SCFM per inch of air curtain at 80 psig then the air knife would be moving 116 SCFM per inch of air curtain. That’s a lot of air!

Also the fact that entraining ambient air is just moving the ambient air with the energy within compressed air makes process is extremely quiet. This is because the outer layers of the total developed flow are lower in velocity, and serve as a sound-attenuating boundary layer.  The sound level of a Super Air Knife at any length is only 69dBA.  That’s about as loud as someone talking at normal speech 3’ away from you.

These Nozzles Clean Blind Holes, Pipe Inside Diameters, Tube, Channels and More

EXAIR manufactures a variety of Air Nozzles and Jets . Back Blow Air Nozzles can help reduce cost, clean hard to get to areas in small diameters, pipes, tubes, channels and holes. These nozzles are designed to remove debris from pipes, blind holes, and other areas where it is difficult be effective. Sometimes it is a bad idea to blow debris all the way through a pipe because there may be personnel on the other end or it is simply too long or it may be sealed on an end. 

The Model 1006SS cleans metal shavings from inside a pipe.

The Back Blow Air Nozzles are all made from 316 Stainless Steel with three sizes as outlined below:

Model 1004SS: This is a M4 x 0.5 and delivers the smallest, most effective airflow for cleaning out small diameter tubes, pipes, channels or holes for diameters between 1/4″ up to 1″. Extension pipes available from 6″ up to 36″ in length.

Model 1006SS: The 1/4 NPT Back Blow Nozzle recommended for a wide range of diameters from 7/8″ up too 4″. Extension pipes available from 12″ up to 72″ in length.

Model 1008SS: 1 NPT female and the largest Back Blow Nozzle in stock for diameters from 2″ up to 16″ with pip extensions available from 12″ up to 72″ long.

Model 1306SS-6-CS Heavy Duty Safety Air Gun with 6″ extension and chip shield

These nozzles can also be assembled to our VariBlast, Soft Grip, Heavy Duty and Super Blast Safety Air Guns. EXAIR safety air gun options include chip shields and pipe extensions up to 72″ long.
