In a recent application for a new installation, an end user of EXAIR products needed a way to remove defective material from a production line. At times, the defective items would fall along a conveyor, and the end user wanted to install an effective, efficient blowoff system to address multiple points along the conveyor. Further to the complexity of the application, the end user needed a product that would not damage the product any further, as they reworked those items to reduce total scrap rates.
Initially, we considered a series of PVDF Super Air Knives, one of which could be triggered “ON” when material was detected. But, the material size is relatively small, leading to the installation of many, many small Super Air Knives. This solution was viable from a performance perspective, but further review found a more economic solution.
We then considered Super Air Nozzles. Perhaps a series of small, efficient nozzles, controlled in groups of (5) or (10), could provide the desired blowoff force. But, what about the need to not damage the product if in contact with the blowoff device?
This is where the PEEK plastic, model 1109-PEEK, became a perfect fit. A series of 1109-PEEK nozzles provided the necessary blow off force, consumed minimal compressed air, and provided a non-damaging, non-marring solution. When controlled in clustered groups, the specific section of the conveyor could be cleared of the defective material, blown into bins for reworking.
These attributes of the 1109-PEEK nozzle, along with high chemical resistivity, and a high temperature range (up to 160°C / 320°F) make it a viable choice for a variety of applications. Maybe that’s why it is currently nominated for a Plant Engineering Product of the Year Award in the Compressed Air category – Please VOTE for the Precision Air Nozzle here.
