No Drip Siphon Fed Round Air Atomizing Nozzle

1/8 FNPT, 1/4 FNPT and 1/2 FNPT no drip siphon fed round pattern nozzles preserve precious liquids and protect product finished from drips.

1/8 FNPT, 1/4 FNPT and 1/2 FNPT no drip siphon fed round pattern nozzles preserve precious liquids and protect product finished from drips. They are a good choice where no liquid pressure is available and a thin coating is needed at a specific area. Flow rate is adjustable via the adjusting valve. 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 round pattern nozzles provide the most liquid flow of any siphon fed nozzle. Made from 303SS for corrosion resistance. Siphon or gravity fed for non-pressurized applications.

Atomizing Nozzle Standards and Certifications

CE Compliant

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.

Conflict Mineral Free

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.

Droplet Size

Droplet size illustration

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")!

Spray Angle

Spray angle illustration

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:

Spray Angle

Model Family Minimum Angle Maximum Angle
Internal Mix Narrow Angle Round Pattern- AN1010SS, AN2010SS, etc. 20° 45°
Internal Mix Wide Angle Round Pattern- AW1010SS, AW2010SS, etc. 50° 90°
