Exair Model SR1020SS 1.9 GPH 1/4 FNPT Siphon Fed Round Atomizing Nozzle

EXAIR’s 1/8 FNPT, 1/4 FNPT and 1/2 FNPT siphon fed round pattern nozzles are great 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. Siphon or gravity fed for non-pressurized applications.

Applications

Advantages

Atomizing Nozzle Materials

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).

Accessories

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.

Atomizing Nozzle Standards and Certifications

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.

Awards – Internal Mix Atomizing Nozzle

EXAIR’s Internal Mix Atomizing Nozzles were a winner of the 2011 New Equipment Digest King Awards. The Internal Mix Atomizing Nozzle family won in the Fluid/Pneumatic Power category.

EXAIR’s Internal Mix Atomizing Nozzles were a finalist in the 2011 Plant Engineering Product of the Year Awards. The Internal Mix Atomizing Nozzle family placed in the Fluid Handling category.

Droplet Size

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

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:
