When we receive calls about Air Amplifiers, it would seem that some people are a bit confused about what these things actually do. They usually end up assuming that Air Amplifiers increase pressure. This is not actually so.
Instead of amplifying pressure, Air Amplifiers multiply the amount of air volume (CFM) that is moved toward a target for a blowoff, cooling or ventilation application. For these kinds of applications, having more air volume makes for better performance to carry away more debris, heat, or fumes.
One quick example is that of a pipe manufacturer. When they cut the pipe to length and machine a chamfer on one end, they need to blow out the chips that land inside the pipe. They had been using a simple 3/8″ ID hose mounted into position to do it. While the airflow was reasonably strong, it was not of sufficient volume to create a large enough airflow in a 6″ diameter pipe. So, the customer switched to using a model 120021 (1-1/4″ Super Air Amplifier) on the end of their 3/8″ hose.
Now, they not only have the original volume of air coming from the hose, but an additional 18 parts of room air that is drawn in through the Air Amplifier and accelerated onto the target to create a much larger volume of airflow going through the pipe. The effect in this application is that the air velocity in the pipe was increased enough to blow out all the remaining chips much better than the air hose alone.
This is just one example of how you can simply add one of our products to the end of an existing compressed air pipe and increase your performance in any application. If you can think of any such similar applications you have, perhaps you should consider adding an Air Amplifier to improve things significantly.
