EXAIR’s new adjustable air amplifier from Compressed Air Australia offers a simple, low cost approach 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 and moving parts to wear out.
Adjustable air amplifiers utilise the Coanda effect (a basic principle of fluidics) to produce outlet flows up to 24 times the compressed air consumed. The compressed air consumed exhausts through a ring nozzle, attaches to an internal contour and then flows towards one end. It also 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 and velocity outlet flow. When set to a 0.002” (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 83dBA. The vacuum and discharge end can be ducted by using a standard hose or tube.
Applications include cooling hot parts, exhausting smoke and fumes, distributing heat in ovens or moulds and drying components. Adjustable air amplifier is constructed from aluminium or stainless steel. These amplifiers are available in additional sizes ranging from 3/4" (19mm) up to 4" (102mm) diameter.
