EXAIR will be giving away a free 2” Super Air Nozzle with the purchase of any EXAIR Line Vac from September 1st through October 31st, 2017. This special promotion will apply to all versions of Line Vac orders, whether aluminum, stainless steel, heavy duty, threaded/non-threaded, or 316SS sanitary flanged. Order within the promotional period and receive the free model 1122, a value of $65.00! The 2″ Flat Super Air Nozzle is more durable than plastic flat nozzles, operates at lower noise levels and produces a powerful blast of compressed air in a laminar sheet.
Line Vacs provide a fast, easy way to pneumatically transfer dry materials from one location to another. They eliminate the need to have personnel manually transferring materials via bag, super sac, or bucket-and-ladder setups. Doing so reduces worker fatigue and allows conveyance to occur simultaneously with other process operations.
What kind of an impact can this have? Here’s a link to a recent blog post where an EXAIR Line Vac saved the end user from having to shut down their conveyor to allow cleaning of spilled material underneath. And here’s a link to an application using Line Vacs to empty and refill a large tank full of desiccant. And here’s a link to an application where we customized a Line Vac for conveyance of dog bedding material. You get the idea…
Depending on application parameters such as bulk density of the material (lbs/ft³ or kg/m³), conveyance height/distance, and required conveyance rate, we can size a Line Vac properly through the support of our Application Engineers who have years of experience working with these products and their implementation into industrial solutions.
We’re here to help you find a pneumatic conveyance solution for your application, and earn a free nozzle in the process. Contact our Application Engineers for assistance today.
The image above shows a test at a customer’s facility to move a small particulate to a height of 7m (23’) with an EXAIR Line Vac. This particulate is used in the production of hand warmers and the end user needed a method to convey the material out of 55 gallon drums.
This same customer purchased a 2” Heavy Duty Line Vac from EXAIR in 2014 which is still in use and functioning well. So, when it came time to find a pneumatic conveyance solution for this material, they knew where to go.
And, we knew just the questions to ask to determine the best Line Vac solution. In order to do so, we had to determine the following:
Bulk density of the material
Size of the material
Required conveyance rate
Available compressed air supply
Bulk density was rather low at 320kg/m³ (~20 pounds/ft³), with a particle size between 3-5mm (~1/8”-3/16”). The conveyance height in this application was 5-7m (16.5-23ft.), with a distance of 1-2m (3.3-6.6ft) and a desired conveyance rate of over 4kg (8.8 pounds) per minute.
The customer ran a test with the 2” Line Vac they have on site and the results were excellent. Their only question was whether they could achieve the needed conveyance with a smaller unit, thereby reducing compressed air consumption and operating cost of the application.
In this case the answer was clear that a smaller Line Vac could be used due to the low bulk density of the material. By reducing the size of the Line Vac to 1”, or perhaps 1.5” we could reduce the compressed air consumption and still meet the required performance need.
EXAIR Line Vacs have, once again, brought a viable solution to this industrial facility. If you have a similar application or would like to discuss pneumatic conveyance needs, contact an EXAIR Application Engineer. We’ll be happy to help.
Below is a video showcasing the model 6850 Drum Cover. The Drum Cover is a new product from EXAIR that will help to filter pneumatically conveyed products from the air used to move them. If you would like to discuss a conveyance application or whether this product would fit your need, please contact an Application Engineer.
