Air Nozzles and Jets Overview

Engineered Air Nozzles and Jets reduce noise levels and air costs.Upgrade your blowoff, cooling, and drying operation to the award winning Super Air Nozzles!

What Are Air Nozzles and Jets?

A simple solution to reduce excessive air consumption and noise levels on compressed air blowoff operations. EXAIR Air Nozzles and Jets produce outlet flows up to 25 times compressed air consumption using a small amount of compressed air as the power source. Many power companies now provide attractiverebates to plants who switch to engineered Super Air Nozzles!

Why Air Nozzles and Jets?

Air savings, compared to open copper tubes or pipe nipples commonly used for blowoff can be as high as 80%. Less compressed air means less noise. The typical noise level reduction is 10 dBA. All EXAIR Air Nozzles and Jets meet OSHA maximum dead-ended pressure and sound level requirements.
ANJ1 Air Nozzles and JetsAn open 1/4" (6mm) copper tube, by contrast, ejects pure compressed air at up to 40 standard cubic feet per minute (1133 SLPM), the entire output of a 10 horsepower compressor. Annual energy cost can exceed $1,000 per year (U.S.Dollars).
Noise levels in excess of 100 dBA are commonly produced. When supply pressure
exceeds 30 PSIG (2 BAR), an open jet violates OSHA static pressure requirements.

How Air Nozzles Work

Air Nozzles use the coanda effect or small directed nozzles to amplify compressed airflow 25 times or more. As illustrated on the right, compressed air (black arrows) is ejected through a series of nozzles on the outer perimeter. As the air travels along the outer wall of the nozzle, surrounding air (blue arrows) is entrained into the stream. The airstream that results is a high volume,high velocity blast of air at minimal consumption. The air is always ejected so it can vent safely, well below OSHA dead ended pressure requirements should the nozzle end be blocked.

Reduce Noise Levels

High noise levels are a common problem for many plants. Compressed air noise often exceeds OSHA noise level exposure requirements, resulting in hearing loss to those working in close proximity. Noisy blowoffs at 80 PSIG (5.5 BAR) that produce noise levels of 100 dBA can be reduced to only 74 dBA when using a Super Air Nozzle. At that pressure, it is still possible to obtain hard-hitting force without the high noise.
