Atomizing Nozzles – No Drip Deflected Flat Fan and 360° Hollow Circular

Published on by 2 Comments

EXAIR manufactures three types of Atomizing Nozzles – Internal Mix, External Mix, and Siphon Fed.  Within the Internal Mix family, there are two specialty nozzles, the Deflected Flat Fan and the 360° Hollow Circular patterns.

Internal Mix nozzles are for pressure fed applications not requiring independent air and liquid control.

The model AD2010SS is the No Drip version of the Deflected Flat Fan and is shown below. Our patented No Drip design prevents unwanted post spray drips from wasting expensive fluids or ruining product finishes. The benefit to this design is that no secondary compressed air line is necessary to activate the on/off valve for the liquid, which is the case for competitive nozzles.

The Deflected Flat Fan patterned nozzle is designed for applications where space is a limited.  The spray pattern is at a right angle to the orientation of the nozzle, allowing the spray to be placed precisely where it is needed in tight quarters.  They are ideal for coating the insides of enclosures and ductwork.

The 360° Hollow Circular patterned nozzle is designed for applications where the spray pattern is to be orientated away form the nozzle in all directions.  They are ideal where a smooth and even coating is needed on the internal surface of a pipe or duct.  They are also good for processed where a mist is needed over a large area, including dust suppression, humidification, and cooling.

The No Drip feature is a patented† design that has the added benefit of positively stopping the liquid flow when the compressed air is shut off. Post spray liquid flow can cause quality issues from unwanted drips on painted or coated surfaces.  Also, the No Drip feature helps to conserve and save on liquid use, reducing costs of expensive coatings or chemicals.

When the compressed air supply is shut off, the No Drip nozzle positively seals off the flow of liquid, eliminating over spray and drips. The design allows for just one compressed air line, there is no need for an additional to control the No Drip mechanism.

Compressed Air Uses In Industry

Published on by Leave a comment

Air Compressor

There are so many uses for compressed air in industry that it would be difficult to list every one of them as the list would be exhaustive.  Some of the uses are the tools used in production lines, assembly & robotic cells, painting, chemical processing, hospitals, construction, woodworking and aerospace.

It is considered as important as water, electricity, petroleum based fuels and often referred to as the fourth utility in industry. The great advantage of compressed air is the high ratio of power to weight or power to volume. In comparison to an electric motor compressed air powered equipment is smoother.  Also compressed air powered equipment generally requires less maintenance, is more reliable and economical than electric motor powered tools.  In addition they are considered on the whole as safer than electric powered devices.

Even amusement parks have used compressed air in some capacity in the operation of thrill rides like roller coasters or to enhance the “wow factor” of certain attractions. Compressed air can be found in your dentist’s office where it is used to operate drills and other equipment. You will find compressed air in the tires on your car, motorcycle and bicycles. Essentially, if you think about it, compressed air is being used nearly everywhere.

Here at EXAIR, we manufacture Intelligent Compressed Air Products to help improve the efficiency in a wide variety of industrial operations. Whether you are looking to coat a surface with an atomized mist of liquid, conserve compressed air use and energy, cool an electrical enclosure, convey parts or bulk material from one location to another or clean a conveyor belt or web, chances are we have a product that will fit your specific need.

Atomizing Nozzles Can Apply Even Coatings
Super Air Amplifier
Air Amplifiers pull in a large volume of ambient air to increase air flow volume and are great for cooling applications!
Heavy Duty Threaded Line Vac
For conveying heavy or abrasive products the Heavy Duty Threaded Line Vacs have male NPT Threads to make permanent and rigid installation into a piping system a breeze.

If you would like to discuss quiet, efficient compressed air products, I would enjoy hearing from you…give me a call.

Product Overview: No Drip External Mix Atomizing Spray Nozzles

Published on by exaircorpLeave a comment

EXAIR’s Atomizing Nozzles are commonly used to clean, cool or coat parts as well as humidification or to control dust. They are constructed of 303ss, providing superior corrosion resistance and are able to withstand temperature up to 400°F (204°C).

The Atomizing Nozzles are separated into 3 categories – Internal Mix, External Mix and Siphon Fed.

For today’s topic, we will focus on the No Drip External Mix Atomizing Nozzles.

No Drip External Mix Atomizing Nozzles provide the highest flow rates

The External Mix Atomizing Spray Nozzles require a pressurized liquid source and compressed air source to produce a mist of atomized liquid. With the liquid and air being mixed external to the nozzle, they are able to handle higher viscosity fluids above 300 cP.

Our patented No Drip feature positively stops the liquid flow when the supply air pressure drops below 20 PSIG for 1/8″ NPT Nozzles or 30 PSIG for the 1/4″ or 1/2″ NPT. By incorporating this feature into the design, it eliminates the need for any additional valves or supply lines.

Available flow rates range from 2 GPH for our Model # EF9010SS 1/8″ No Drip External Mix Narrow Angle Flat Fan Pattern and up to 303 GPH for the Model # EF6010SS 1/2″ No Drip External Mix Narrow Angle Flat Fan Pattern.

When making a selection, there are 5 common considerations to take into account:

  1. How much liquid flow do I need?
  2. Is the liquid pressurized?
  3. What is the viscosity of the liquid?
  4. How wide of an area needs to be treated?
  5. What type of spray pattern fits the application?

If you have an application requiring a fine mist of atomized liquid or if you’d like to discuss another product or application, contact one of our application engineers for assistance.
