3 inch Adjustable Air Amplifier To Cool, Dry and Exhaust


EXAIR’s new 3" Adjustable Air Amplifier offers a simple, low cost way to move high volumes of air to cool, vent, exhaust and dry. The airflow can be easily adjusted from a “blast” to a “breeze” to match the application requirements. There are no impellers or moving parts to wear out.
Adjustable Air Amplifiers utilize the Coanda effect (a basic principle of fluidics) to produce outlet flows up to 24 times the compressed air consumed. The compressed air exhausts through a ring nozzle, attaches to an internal contour, then flows toward one end. It creates a vacuum on the opposite end that pulls free air through the unit. This induced air mixes with the compressed air for a high volume, high velocity outlet flow. When set to a .002” (0.05mm) air gap supplied at
80 PSIG, the outlet flow is 2,323 SCFM when measured 6” (152mm) from the outlet. Sound level is low at 83 dBA. The vacuum and discharge end can be ducted using standard hose or tube.  
Applications include cooling hot parts, exhausting smoke and fumes, distributing heat in ovens or molds, and drying components. Construction is aluminum or stainless steel. Prices start at $242. Additional sizes from 3/4" (19mm) up to 4" (102mm) diameter are available from stock.
