EXAIR’s Atomizing Spray Nozzles are used to clean, coat, or cool parts and they also lend themselves very well to humidification and dust control. They are constructed from rugged and durable 303 SS to provide corrosion resistance and they can operate in temperatures up to 400°F (204°C). All EXAIR Atomizing Spray Nozzles are also CE compliant.
Atomizing Nozzles are separated into 5 categories – Internal Mix, External Mix and Siphon Fed, Deflected Flat Fan, and Internal Mix 360° Hollow Circular Pattern. They are available in 1/8″, 1/4″ & 1/2″ NPT to make it easy to provide the coverage and flow rate you need for nearly any application. For today’s focus, we will discuss the No Drip External Mix Atomizing Nozzles.
External Mix Atomizing Nozzles have the highest flow rates and are ideally suited where precise liquid flow is required and both the air and liquid are pressurized. Also the External Mix Atomizing Spray Nozzles can easily atomize liquids with a viscosity above 300 cP (Centipoise).
Centipoise is defined as a dynamic viscosity measurement unit. A Centipoise (cP) is a non-SI (non-System International) measurement unit of dynamic viscosity in the centimeter gram second (CGS) system of units.
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. They are available in flow rates that range from less than 2 GPH (7.57 LPH) for our Model EF9010SS 1/8 NPT No Drip External Mix Narrow Angle Flat Fan Pattern and up to 303 GPH (1,147 LPH) for the Model EF6010SS 1/2 NPT No Drip External Mix Narrow Angle Flat Fan Pattern.
When making a selection, below are some points to consider:
- Volume of liquid required?
- What is the viscosity of the liquid?
- What type of spray pattern fits the application?
