EXAIR Case Studies Share Succe$$

EXAIR provides many informative tools to help you decide which of our products will work best for you. We have a qualified staff of Application Engineers, a comprehensive catalog, Installation Sheets, Blogs, and a library of Case Studies, to name a few. Following is more about our Case Studies and how they can be helpful.

EXAIR keeps a library of Case Studies for your reference. The Library s is also organized by product so you can easily find the information and product you have interest. These case studies summarize how our customers have purchased, used, and benefited from our products and their purchase. These studies focus on our products and your project, we do not use our customer names and only use photos and verbiage that you approve and share with us.

The process to develop a Case Study is as easy as talking to one of our Application Engineers. We will discuss your project and work with you to decide the wording and photos that you approve for the study. Once the study has been completed and approved we can discuss a credit on your purchase or percentage discount on your next purchase. This becomes a “win, win” for both you and EXAIR.

EXAIR appreciates a good success story, and we want to encourage you to share your success from using one or more of our products. This is why EXAIR incentivizes Case Studies. We will offer a discount to any company who will provide enough information to produce a case study. If you have interest to create a Case Study (and save money) on your next project please contact one of our Application Engineers so we can discuss your application and goals.

Heavy Duty Line Vacs: Made for Abrasive Materials and/or Higher Throughput

The Heavy Duty Line Vacs are made from a hardened alloy steel for abrasion resistance.  The generators inside these Line Vacs are more powerful than the standard models; so, that they can also convey heavier materials at higher conveyance rates.  They can reach rates as high as 40 lbs./min. (18.2Kg/min) of material.  With the hardened alloy construction, they are great for sand blasting applications, ceramic, glass, garnet, tumbling media and steel shot.  They are manufactured with inlet and outlet connections for ship-on hoses or threaded pipes.  EXAIR stocks the Heavy Duty Line Vacs in the range from ¾” (19mm) to 3” (76mm) for both hose and NPT connections.  These Line Vacs are our most powerful design with great wear resistance.

The table below gives a quick comparison of the EXAIR Light Duty Line VacStandard Line Vac & the Heavy Duty Line Vac models.  The test shows the 2″ size in each model conveying Rock Salt over two different horizontal distances.  As expected the Heavy Duty Line Vac conveys more material in less time!

Heavy Duty Line Vac Distance

The performance of the Heavy Duty Line Vac’s is nothing short of amazing!  With vacuum ratings between -144 to -20 inches of water column, it is more than likely there is a Heavy Duty Line Vac model that will suit your application.

HD Line Vac Performance

Models range from 3/4″ OD to 3″ OD either in smooth bore or NPT threaded models for the ultimate in versatility.  The table below shows the different Heavy Duty Line Vac Models and their respective recommended kit, which includes a pressure regulator for fine tuning performance, filter separator to keep the compressed air supply clean and a mounting bracket.

Laminar and Turbulent Air Flow

I have a manufacturing background primarily with automotive and plastic injection molding. I used compressed air but I will admit that I did not know the difference between Laminar and Turbulent air flow. You’ll often hear EXAIR refer to laminar vs turbulent flow when discussing our blow off of products. I will briefly describe the difference between the two and hopefully we all learn something new. In any blow off process or application, laminar airflow is going to be much more effective at eliminating pressure drops, blowing product and reducing noise levels than the turbulent air flow. To read more about the math behind it, check out my colleague John Ball’s previous post here.

A good example of an EXAIR product that delivers a laminar air flow are our Super Air Knives. The super air knife offers a more efficient way to clean, dry or cool parts, webs or conveyors. They deliver a uniform sheet of “Laminar” airflow across the entire hard-hitting force. The Super Air Knives deliver a uniform sheet of air that has the same force across the entire length.

The efficiency of EXAIR’s Super Air Knife delivering the laminar air flow becomes more valuable when comparing the effectiveness to a blower operated knife or fans. A fan “slaps” the air, resulting in a turbulent airflow where the airflow particles are irregular and will interfere with each other. A laminar airflow, by contrast, will maintain smooth paths that will never interfere with one another, which allows for maximum velocity and can produce higher force levels.

EXAIR had a customer needing help applying icing on snack cakes. As baked sponge cakes moved down a conveyor, a continuous ribbon of icing was applied to the individual cakes. Trying to make a clean break in the icing was next to impossible. Mechanical blades needed constant cleaning. Compressed air through a series of holes in drilled pipe used too much air, was noisy and did not make a clean break.

The solution was using an EXAIR Stainless Steel Super Air Knife. A photo eye detected space between cakes turning the compressed air on at the precise moment to apply a uniform airflow and velocity against the ribbon of icing, creating a nice clean break. The stainless steel Air Knife was the best choice for this application. Since there was no contact with the icing, no additional cleaning was required. The Laminar flow of the Super Air Knife had uniform velocity across the entire length and broke the ribbon of icing evenly. This successful result would never have been possible with turbulent air from drilled pipe, nozzles or a blower.

The Super Air knives are just one of many of EXAIR’s Intelligent Compressed Air products. When planning your next project that requires compressed air please contact one of our many Application Engineers for assistance. EXAIR takes pride in our products and customer service.

Turn Ordinary Pipe Into A Powerful Transfer System w/ EXAIR’s Threaded Line Vac!

EXAIR’s Line Vacs are the ideal low-cost solution for bulk material transfer or trim and scrap removal. Available with NPT threaded connections, EXAIR’s Threaded Line Vacs allow you to convert ordinary pipe into a powerful conveying system for parts, scrap, trim, and other bulk materials. With performance identical to that of the Standard Line Vac, the Threaded Line Vac is available in sizes ranging from as small as 3/8 NPT and up to 3” NPT. There’s a suitable Line Vac for most standard sized NPT pipe common in any industrial facility.

The Threaded Line Vac is available in a range of different materials: Aluminum, Type 303 Stainless Steel, Type 316 Stainless Steel, and as a Heavy Duty conveyor constructed of a hardened alloy steel for use in abrasive applications. Where most materials or hard anodized coatings wear out or wear off over time, the Heavy Duty Line Vac is the ideal solution for heavy and abrasive materials. In addition to being abrasive resistant, the Heavy Duty Line Vac is also more powerful and suitable for longer vertical and horizontal transfer distances.

Each style of Threaded Line Vac is also available as a High Temperature option. By replacing the traditional o-rings with graphite seals, we’re able to provide a solution capable of withstanding temperatures up to 900°F!!!

The conveyance rate through the Line Vac is infinitely adjustable by regulating the air pressure supplied to it. At lower pressures, the conveyance rate (and air consumption) will decrease. At higher pressures, the conveyance rate will increase. If you have a Threaded Line Vac with the standard performance but need just a little bit more, the option also exists for a High Power unit that would match the performance of the similarly sized Heavy Duty. This can be ordered from the factory with an “HP” prefix, or modified yourself. Check out our video to see just how simple it is to get more out of your Threaded Line Vac.

With all sizes and materials on the shelf and in stock, we’re able to get a solution out to you quickly. We’ll ship out the very same day for stock orders received by 2:00 ET. Backed by our Unconditional 30 Day Guarantee, you’re able to make sure it is the right solution for you before committing to keep it. If you have an application that could be better served with an in-line pneumatic conveyor, give us a call. We’ll be happy to help you determine the most suitable size for the application.
