1/8 FNPT and 1/4 FNPT no drip siphon fed flat fan pattern nozzles preserve precious liquids and protect product finished from drips. Made from 303SS for corrosion resistance. They are great where no liquid pressure is available and a thin coating is needed over a wide band. Siphon nozzles work best with a suction height of 36" (914mm) or less. Since these nozzles are siphon fed, the compressed airflow draws the liquid in and mixes it internally. Liquid flow is dependent both on the gravity or suction height and the airflow. Siphon fed flat fan pattern nozzles are the best choice where liquid is needed over a broad band such as a moving assembly line. Siphon or gravity fed for non-pressurized applications.
Type 303 Stainless Steel - All of EXAIR's Atomizing Nozzles are constructed with Type 303 stainless steel, which can resist high temperatures and corrosive environments. They are designed for environments with a maximum operating temperature of 800°F (426°C).
Mounting Brackets - available for 1/8 FNPT, 1/4 FNPT and 1/2 FNPT models. Provides a secure mount for EXAIR's Atomizing Nozzles. Constructed of Type 301 stainless steel.
EXAIR Atomizing Nozzles comply with the EU General Product Safety Directive (2001/95/EC) and meet the noise limitation requirements of the EU Machinery Directive (2006/42/EC). All sound level measurements are taken at 3 feet away.
Look for this symbol to designate conflict mineral free products throughout our website. EXAIR supports Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act and we are committed to compliance with the conflict minerals rule in order to curb the illicit trade of tin, tantalum, tungsten and gold in the DRC region. EXAIR is using the CMRT 3.02 template to document our supply chain and commitment to conflict free products.
One of the primary reasons atomizing spray nozzles are used is because of their fine droplet size. Benefits of fine droplet size include even coating and liquid conservation. For reference, a large raindrop is around 6,000 microns (0.236") in diameter. Standard liquid nozzles produce droplet sizes ranging from 4,000 microns (0.157") down to 300 microns (0.012") in diameter. EXAIR's Atomizing Nozzles produce minuscule droplet sizes in the range of 100 microns (0.004") to 20 microns (0.0008")!

The Spray Angle is the trigonometric angle created by the width of the spray pattern and the distance at which it is measured. This angle can vary greatly within a given family of atomizing nozzles depending on flow rates and pressures, but will generally fall into the ranges below:

What fluid was used to determine the flow rates given in the catalog information?
Published performance data was obtained by testing the Atomizing Nozzles with ordinary tap water. The viscosity of your fluid will determine which style Atomizing Nozzle will be best for you. Please feel free to contact an Application Engineer for selection assistance.
What is the maximum viscosity that can be dispensed through each type of atomizing nozzle?
What is the maximum draw height a Siphon Fed Nozzle can draw from?
The Siphon Fed Atomizing Nozzles can draw up to a 36" height. If drawing from a container, this means you would want the bottom of the container to be no lower than 36" below the liquid inlet to the atomizing nozzle.
How can I tell what Spray Nozzle I have?
The liquid cap and the air cap are both stamped with part identification.
Contact an Application Engineer and with the combination of the two part identification numbers, they will be able to tell you the nozzle you have.
What is the maximum operating temperature for the Atomizing Spray Nozzles?
The maximum operating temperature is 400° F (204° C)
How is the valve stem used to adjust the nozzle's liquid flow?
The Atomizing Spray Nozzles come pre-set from the factory in a fully open position. To reduce or stop flow, turn the stem clockwise. Be careful not to over tighten the stem as damage to the stem or liquid cap can occur. Once completely closed, 3-4 turns counterclockwise will result in a fully open flow.
