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.
In this summer of 2016, we are nearing the beginning of one of the largest sporting events on the planet, The 2016 Summer Olympics. At the heart of this celebration will be sporting events of all kinds. And in the tradition of the Olympics there is always a gold, silver and bronze winner to award the top three athletes in each event.
EXAIR is participating in a competition as well. It isn’t one of a sporting nature, but rather, one of ingenuity and innovation. Flow Control Magazine holds an annual competition for innovations in new products available in industry and we have entered the No Drip Atomizing Nozzle into the competition.
In general, Atomizing Nozzles are used for the application of high value fluids within industrial processes. In some cases where the Atomizing Nozzles are mounted above the target, residual fluid that is left inside the nozzle body can drip out when de-energized and cause un-wanted blemishes on the target surface.
EXAIR No Drip Atomizing Nozzles allow for external adjustment of compressed air and liquid inputs to adjust the liquid spray flow rate as well as droplet size for a wide range of applications. That’s pretty common amongst atomizing nozzles in general. So what is so innovative about the No-Drip Atomizing Nozzles?
We have found a way to control the on/off function of the atomizing spray which supports the no-drip feature as well as the atomizing flow with only one compressed air supply. Most other manufacturers require a nozzle that has a separate control for the small valve within the nozzle and another for the airflow that atomizes the fluid coming through. It is this innovation that dramatically improves the simplicity with which these nozzles can be installed into an application and controlled through typical air automation techniques. It was innovative enough that the US Patent Office granted EXAIR a patent on the design (Patent # 9156045). So, we’ve made the No-Drip Atomizing Nozzle available with 3 different spray patterns and 14 different liquid volume options to suit a wide variety of application need. Operating pressures can fall anywhere between 30 – 250 PSIG to atomize fluids up to 300 centipoise.
If you agree with the US Patent Office on the innovation and think that EXAIR’s No Drip Atomizing Nozzles should be a winner in this competition, we would appreciate your official vote.
