Full-Flow Air Knife is The Right Choice in Fiberglass Blanket Application

Last week I took a call from an automation company who had been working with a fiberglass insulation manufacturer on a blanket rolling application. After the manufacturing process, the fiberglass blankets are rolled up and a protective film wrap is placed around the ends. The end user was currently using a section of 3/8″ pipe with several 1/8″ holes drilled along the length to hold the ends of the blanket in place as the wrap is applied. The current setup was using a lot of compressed air and was creating an unbalanced airflow that was strong at one end but much weaker at the other, causing the ends of the blanket to begin to “roll up” and either damage the shrink wrap or the blanket itself. They also believed the setup was starving other processes in this particular area of the plant and initially were considering purchasing an auxiliary air compressor but due to the capital expense, instead reached out to the automation company for other options.

We have worked with this particular automation company in the past so they were familiar with our product offering and knew they wanted to use an EXAIR Air Knife in the application. However, they were unsure if they wanted to use our Super, Standard or Full-Flow Air Knife . Their need was to improve process results, reduce the air usage and to fit inside a tight area.

Full-Flow Air Knife available from STOCK in lengths from 3″ – 36″, aluminum or 303SS construction

I recommended they use our 36″ Full-Flow Air Knife in the application. The Full-Flow Air Knife is our smallest profile offering at only 1″ x 1.03″ (aluminum construction) and uses a 30:1 amplification rate (entrained air to compressed air) to produce a high velocity, laminar curtain of air that travels the entire length of the knife. These units are in stock, ready to ship, offering the end user a low cost, quick solution to replace the existing drilled pipe.
