Exair recently worked on an application with a manufacturer who was having issues with their labeling process. The sticker label is applied to the side of their container by a print roller and then passes by a 6” homemade manifold system with 3 nozzles to help permanently affix it n(see below). They were experiencing irregularities/air bubbles in the label and realized they were getting an uneven airflow which was stronger at each end nozzle but the middle nozzle had very little flow. They were operating at around 80 PSIG and previously tried to lower the pressure but the label would start peeling off. If they increased the pressure they were experiencing tearing and ripping in certain areas of the label. Another issue was the loud noise level. They were having to stop the line and turn off the air so an operator could manually replace the label. They emailed to Exair's person a picture of the manifold and asked if EXAIR could improve their process.
After reviewing the picture and further discussing their application, we recommended using one of our6” Aluminum Super Air Knives. The Super Air Knife , with a 40:1 amplification rate (surrounding ambient air to compressed air), provides a high velocity laminar sheet of airflow the entire length of the knife. By continuing to operate at 80 PSIG, the Super Air Knife will produce a velocity of 11,800 feet per minute (6” away from target object) and consume only 17.4 SCFM (2.9 SCFM per inch of knife) with a low noise level of only 69 dBA.
By replacing the manifold, the customer was able to improve their process, decrease their air consumption and increase their personnel’s safety.
