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

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.

Model AD2010SS – No Drip Internal Mix Deflected Flat Atomizing Nozzle

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 model AT2010SS is the No Drip version of the 360° Hollow Circular and is shown below.

AT2010SS – No Drip Internal Mix 360° Hollow Circular Atomizing Nozzle

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.

New Atomizing Spray Nozzles That Will Change Your Spraying Process

EXAIR has continued to build on a large catalog of Intelligent Compressed Air Products. In catalog 27 we introduce (2) new Atomizing Nozzles to add to our product’s functionality and versatility. Today, I want to talk about one of the spray nozzles we added. Don’t worry! Next week, I will talk about the second nozzle, if you must look ahead follow this link.

Deflected fan in use Deflected Fan

Our new nozzle is the Internal Mix Deflected Fan Nozzle. The nozzle produce a flat fan of atomized liquid at a right angle to the nozzle’s orientation. The nozzle is designed for pressure fed application, where the pressurized liquid does not need to be controlled independently from pressurized air. In cases where space is limited, the directed flat fan frees up over 3 3/4″ extra inches of height clearance on the standard nozzle. With the no drip spray nozzle, it can gain you over 4 inches of clearance. This clearance can be very important when you consider the coverage you gain in a tight space.

Deflected Fan Advantage

Let me give you an example. A customer is running a 28 inch conveyor of machined parts through a 6″ tunnel and wishes to spray a solvent across the parts evenly.  In the past we would have needed to use the AF2010SS No Drip nozzles.  The AF2010SS nozzle would have done a great job, but the nozzle would need to be mounted at the top of the tunnel.  The overall length of the nozzle would limit the spray distance to 2 3/4″ inches.  With only 2 3/4″ of spray, it would require 11 nozzles to cover the 28″ span.  With the AD2010SS the bulk of the nozzle and the no drip body can be mounted behind the spray nozzle, which allows the spray distance to be 5 1/2″ which would cover a wide 8 1/4″ area.  With 8 1/4″ of coverage, what would have required (11) nozzles now only requires (4) nozzles.
