Siphon Fed Air Atomizing Spray Nozzles

 

Siphon fed nozzles are a great alternative for spraying where no liquid pressure is available. EXAIR has 3 sizes from 1/8 NPT, 1/4 NPT and 1/2 NPT nozzles along with “No-Drip” nozzles in the same sizes. Siphon fed nozzles require no liquid pressure and can be used with gravity fed liquids or lift liquids from a siphon height as much as 36′ (91 cm). Siphon fed nozzles work best with thinner liquids up to 200 centipoise.

EXAIR Air Atomizing Nozzles are manufactured from 303 stainless steel for durability and corrosion resistance. The siphon fed nozzles can be easily implemented where a tank can be installed and lower the cost of the installation by not requiring a liquid pump, just point of use compressed air.

No Drip Siphon Fed Round Pattern Atomizing Nozzle

In addition to the sizes and no drip option the siphon fed nozzle comes in two spray patters. The round pattern offers more liquid pass through and can be used in cleaning, rinsing, cooling and coating applications.

2″ Super Air Amplifier Exhausts Welding Fumes

 EXAIR’s Super Air Amplifiers utilize a patented shim design to maintain critical positioning of component parts. This allows a precise amount of compressed air to be released at exact intervals toward the center of the Super Air Amplifier. This creates a constant, high velocity outlet flow across the entire cross-sectional area. Free, ambient air is entrained through the unit, resulting in high amplification ratios. The balanced outlet airflow minimizes wind shear to produce sound levels far lower than other similar air movers.

While most applications utilize the outlet flow of the Super Air Amplifier to blow off or cool a part or material, the ability of the Super Air Amplifier to entrain large amounts of ambient air can also be utilized to convey light materials or to draw in dust, smoke, or fumes from the surrounding environment.

Recently our principal worked with a customer on an application to install the Model 120022 Super Air Amplifier in welding booths. They did have a current fume extraction system in place, but due to the distance between the vent hoods and the operation some of the fumes were still not being captured. The suggestion was to install a 2” Model 120022 at each booth near the origin of the welding fumes. As the exhaust side of the Super Air Amplifiers come in sizes of ¾”, 1-1/4”, 2”, 4”, and 8” the exhaust flow can be ducted with standard size hose. The placed a 2” ID hose onto the exhaust of the Super Air Amplifier which allowed the fumes to be captured into the intake of the amplifier and be carried towards the vent hood.

This eliminated a safety issue for the operators and was much less expensive than redesigning the entire welding booths and current extraction system. With no moving parts to wear out, the Super Air Amplifier requires absolutely zero maintenance when supplied with clean, dry compressed air. After installing onto each of their welding booths, operators were pleased with the performance and we were able to eliminate the safety hazard for this facility.

Coanda effect

 What is Coanda effect?
The Coanda effect is the tendency of a fluid jet to stay attached to a convex surface. It is named after Romanian inventor Henri Coandă, who described it as "the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops.

Compressed air flows through an inlet (1) into the plenum chamber of the Super Air Knife. The flow is directed to a precise, slotted orifi ce. As the primary airflow exits the thin slotted nozzle (2), it follows a flat surface that directs the airflow in a perfectly straight line. This creates a uniform sheet of air across the entire length of the Super Air Knife. Velocity loss is minimized and force is maximized as the room air (3) is entrained into the primary airstream at a ratio of 40:1. The result is a well defined sheet of laminar airflow with hard-hitting force and minimal wind shear.

Henri-Marie Coanda (1885-1972) discovered the Coanda Effect in1930. He observed that a stream of air (fluid) emerging from a nozzle tends to follow a nearby curved surface, if the curvature of the surface or angle the surface makes with the stream is not too sharp. For example, if a stream of fluid is flowing along a solid surface which is curved slightly from the stream, the fluid will tend to follow the surface.
A number EXAIR products are designed to utilize the Coanda Effect and aid their performance. In some products, the Coanda Effect aids to create an amplification area where additional ambient air is drawn into the total airflow to increase total volume of air upon a target. This creates a more efficient and effective product. Also, since not as much compressed air is required, the noise levels decrease for products like EXAIR’s air knives, air nozzles, air jets and air amplifiers. EXAIR has been successful with positive impact for compressed air energy savings and noise reductions helping us meet or exceed OSHA Standard.
