Today, I would like to focus on 2 specific Atomizing Nozzles – our No Drip Internal Mix Deflected Fan Nozzle and our Internal Mix 360° Hollow Circular Pattern Nozzle.
The No Drip Internal Mix Deflected Fan Atomizing Nozzle produces a flat fan of atomized liquid at a right angle to the nozzle’s orientation and is designed for use in pressured fed applications where the liquid doesn’t need to be controlled independently from the pressurized air. This nozzle is the perfect choice in processes where mounting space is limited like spraying solvent on conveyed parts inside a small chamber or coating the inside of an enclosure. The patented No Drip feature positively stops the liquid flow when the supply air pressure drops below 30 PSIG, eliminating the need for any additional valves or supply lines. This is especially beneficial in applications using expensive fluids or where drips can ruin a finished product. This nozzle is available with 1/4″ NPT inlets and flows as high as 6.9 gallons per hour.
Our Internal Mix 360° Hollow Circular Pattern Atomizing Nozzles produce a circular spray pattern, the ideal solution when trying to coat the inside of ductwork or where a broad mist of atomized liquid is necessary, like dust suppression or humidification. Available in 1/4″ NPT with flows as high as 14.7 GPH and spray diameters up to 53″ in diameter depending on air and liquid supply pressures. With the 1/2″ NPT, we can achieve up to 150 GPH with a spray diameter up to 156″. Our standard Atomizing Nozzles also feature an adjustment valve to provide control of the flow rate, making them easy to adapt to a specific requirement.
If you have an application requiring a fine mist of atomized liquid, please contact one of our application engineers and let us know how we can help in making the best product selection to fit your need.
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.
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.
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.
