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 fow and and are much more effective for cooling compaed 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 redcued as well. Nex Flow offers units for testing and welcomes comparisons to competitive models so you can confirm actual results in house..
