Nex Flow™ Air amplifiers are compact, low cost air flow “movers” that are virtually maintenance free. Applications include the venting of fumes and smoke, conveying of low weight materials, and entraining a high volume of air to cool, blow off, and dry. Air Amplifiers use the “Coanda effect” to draw in the surrounding atmospheric air while consuming only a minimal amount of compressed air. These products can amplify airflow up to 17 times (depending on the size) resulting in dramatically reduced levels of noise.
Air Amplifiers (also called Air Movers) draw in atmospheric air from the back of the unit as well as having downstream entrainment further amplifying the flow. They are used for cooling and venting. While the force produced for blow off decreases as the amplifier outlet diameter increases, these Air Movers are ideal for cooling because of the high velocity outlet flow and and are much more effective for cooling compared to air nozzles.
The air amplification “ratio” (hover for definition) varies from 6 up to 17 depending on size of the air amplifier. If the ratio is higher than 17 the velocity could decrease too much and the blow off force would become too weak and ineffective because of inadequate velocity. With much lower velocity the cooling effect is dramatically reduced as well. Nex Flow offers units for testing and welcomes comparisons to competitive models so you can confirm actual results in house..
