A Customized Line Vac Moves Dog Bedding

One of the interesting things about working with a variety of applications on a daily basis, is realizing every answer isn’t cut-and-dry.  There are, of course, times when we can specify the exact amount of compressed air required, or the air volume needed to maintain a specific temperature, but conveying applications tend to be a bit different.

A reseller contacted me with an application in need of moving bedding material for dog beds.  The end user needed a reliable way to move the cotton fill for the beds, and wanted to find a way to limit handling by employees, while maintaining a reliability in the amount of material conveyed.

Due to the light weight and density of the cotton, we considered a Light Duty Line Vac, which has an option of sizes up to 6” in diameter – a benefit to this application because the cotton can cluster in groups up to 5” wide.  So, the end user decided to test a Light Duty Line Vac and fell in love with the concept and results.  But, the conveyance capacity of the Light Duty Line Vac was below the needs of the application, meaning we needed to consider a revision to our initial solution.

Finding a new solution meant exploring a number of different options.  We looked into the standard Line Vacs available from stock, threaded Line Vacs, and custom-made Line Vacs with cam lock fittings.  All the while we kept an eye on the throat diameter of each size, the related compressed air requirements, connection options, and lead time.

An initial concern at EXAIR was the cotton “clumping” and being delivered in a the form of a ball. The “clumping” of the cotton was of relatively little concern to the customer, their bigger indicator of success in this application was in how quickly the bedding material could be conveyed.  Having this as the decision driver led us away from the Light Duty Line Vacs we originally sought, and towards a modified version of our stock model 6087 (4″ aluminum Line Vac) with an additional compressed air inlet machined into the body of the unit.  The additional compressed air inlet was introduced by request from the customer, to provide guaranteed air delivery during higher compressed air flow conditions, brought about through higher operating pressures (not to exceed 250 PSIG).

Finding this custom solution wouldn’t have been possible without the Light Duty Line Vac, its large size availability, attractive compressed air usage, and ability to chip from stock.  We never would have explored this special solution, which the end user went on to implement in 12 locations!  If you’re considering a Line Vac for an application in your facility, consider a Light Duty Line Vac, standard Line Vac, or even a custom solution.  No matter the solution, we’ll be happy to help.
