Custom Products for Custom Applications

Here at EXAIR we pride ourselves on the number of problem solving products we have on the shelf that can ship same day if ordered by 3 PM Eastern Time. But some times a stock product doesn’t quite fit the bill for every application.

Since EXAIR manufactures our products at one location in Cincinnati, Ohio, this gives us the flexibility to do many things like making custom configurations with our Line Vac Systems.  Here is one example of a custom Line Vac and how the customer is using it!

The photo above shows two custom 1″ Aluminum Line Vacs with custom threaded outlets. This customer wanted to use the line vac to remove fumes from a welding application and wanted to attach one of their flame retardant filter bags to the outlet of the Line Vac! These custom threads allowed them to screw the filter bag directly onto the line vac with the added insurance of a threaded connection to prevent sparks from escaping the bag.  

No matter what your application is EXAIR is capable to work with you to create custom solutions for your application. Whether you need a different material, size or dimensions or design, EXAIR is able to meet your requirements. These Line Vacs represent only one of our many product lines that can be custom made to your specifications.

For more information on EXAIR’s Line Vacs or help with customizing any of EXAIR‘s Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

A Customized Line Vac Moves Dog Bedding

gh_LVthr-hd-ld_754x696p

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.

Super Ion Air Knife Assists Brewery with Can Filling Operation

A small brewery called looking for a static removal solution for their can filling, conveyor line. The empty cans are fed from a stacked palletizer that raises up and then an arm pushes the cans over to a large feeder tray where they are then funneled down a chute that narrows until the cans are in a single row. They run 2 separate cans on the same line at different times. The first can is painted and seems to feed fine to the conveyor. The second can is shrink wrapped with a film label. As the wrapped cans are fed down the chute, they rub against the guide rails of the conveyor and each other generating a static charge, causing them to corral at the opening to the conveyor, 2 – 3 cans wide, which restricts the flow of the cans. The customer then has to halt production and manually clear the line and feed the conveyor.

The area where they are seeing the most problem is right at the narrow opening that takes the cans down to a single row. The width of this opening is roughly 8.5″ wide, so I recommended they mount a 9″ Super Ion Air Knife about 12″ above the opening, flooding the area with ionized air. The Super Ion Air Knife is our Super Air Knife with an Ionizing Bar attached to provide a laminar sheet of ionized airflow across the entire length of the knife. The customer was concerned that their compressed air supply was close to being at max capacity so I suggested they operate the unit at a lower supply pressure. This would not only reduce the air consumption but also control the output flow and velocity so the cans are not disrupted, while still allowing for effective static dissipation.

Static electricity is a common nuisance in canning and bottling applications. If you are experiencing similar problems with your process, please contact one of our application engineers for assistance.

Peanut Butter And The Flat Nozzle

So, the call came in about mid-morning – an operator at a facility that fills plastic jars with peanut butter needed help with an application…

And I almost got stuck thinking about peanut butter. I like food, and peanut butter is near the top of my list. I’ve seen it successfully applied to cheeseburgers, and the peanut butter & bacon sandwich is even a breakfast staple in some of the Boy Scout groups I’ve been involved with. Crunchy or creamy, peanut butter rules.

Never underestimate the power of peanut butter...or bacon...to improve the quality of any sandwich.
Never underestimate the power of peanut butter…or bacon…to improve the quality of any sandwich. And together, they’re unbeatable. Just don’t ask your cardiologist.

Now, I’m a pro, so I didn’t allow this digression to supplant the attention I was giving the caller. The application was simple enough: the nozzle feeding the jars retains a small amount of the product at the tip, which drips off when it’s good & ready, thank you very much. This is oftentimes when the jar is in motion, so this little glob falls right onto the rim of the jar, causing issues with the protective seal, and a continuing mess as this jar with peanut butter on the outside of it travels down the line.

I recommended a Model 1126SSW 316SS 1” Flat Super Air Nozzle, with Swivel Fitting. They can install this to blow precisely where the air flow can direct the last bit of peanut butter from the fill nozzle into the jar, eliminating the mess, and any chance of a faulty lid seal.

The Model 1126/1126SS 1″ Flat Super Air Nozzle is ideal for high velocity, forceful blow off applications
