Cleaning Air Amplifiers
Compressed air amplification products have small air exit “gaps” and if not properly filtered can get dirty and block airflow. But there is an easy way to clean.
No matter how well your compressed air supply is filtered, at some point in time, there will be particulate buildup in the blow-off product used and the most common blow-off products ignored for this are air knives and air amplifiers.
These products operate using an air gap where the compressed air exits over aerodynamically designed surfaces to entrain surrounding air and convert pressure lost as pressure drop and noise into useful airflow. Over time deposits can build up over these surfaces which can negatively affect the entrainment and reduce the output airflow efficiency. Carefully wiping these surfaces can be easily achieved but wiping with care to avoid damage to these surfaces.
However, the problem of particulate buildup can be inside the plenum chambers of the air amplifier or air knife. In this case, it is more complicated. This problem manifests in uneven flow from the air amplifier or knife. This is detrimental to the production process because the cleaning or drying (and even cooling) application for the particular product can be less effective with this uneven flow.
If left too long, the device may need to be removed from production, disassembled, and cleaned if too clogged with dirt and debris. However, when the problem manifests itself with the uneven flow, an easy method to clean is described in the video where you simply keep the air flowing, but at a lower pressure for safety, loosen the body and cap, and blow out the particulate, then retighten,
