Air Operated Conveyors: Line Vacs

Get rid of your buckets and ladders, and add an EXAIR Line Vac. These small units can move large volumes of material. They are a perfect solution for moving things like plastic pellets, textiles, food products, pills/tablets, granules and much more. By adding a small amount of compressed air through the directed nozzles on the Line Vac, you will create a vacuum on one end and a high flow of air on the other to lift and or push your material up and over to a new location.

EXAIR Line Vacs: For bulk material conveyance through lines from 3/8″ to 6″, in aluminum, 303SS, 316SS, or abrasion resistant hardened alloy, available from stock with the widest variety of connections in the industry.

With multiple sizes from 3/8″ up to 4″ (up to 6″ in our Light Duty Options), we can help you select the best size for your application. In addition to sizes, we offer these is the following materials; Aluminum, 303 Stainless Steel, 316 Stainless Steel, High temp 303 and 316 Stainless Steel, a hardened alloy, and in a flanged 316 Stainless Steel. We offer these in the Standard Fitting, a Threaded Fitting, and a Sanitary Flange Fitting. Lastly, we can make these in custom materials and sizes if you have the need.

Line Vacs can convey many things.

We have testing data from materials of many weights and sizes to compare your project to, so that we can help you choose the best size for your application. The information we need starts with the type and size of material. Keep in mind that we will be aerating your product, so we need to be cautious of creating combustible dusts such as flours, grains, pesticides, fine powders and much more. Beyond this, we need to understand the surface area on your product that the air will catch.

We will then need to understand the vertical and horizontal lengths that you need to move your media. For instance, up 10 feet and over 5 feet… With this, we will need to understand the “turn”. Keeping in mind that this is about air flow, 90° turns need to be taken in to account. We will need to add 10-15 feet of length in our calculations to overcome a 90°turn. If you can engineer a gradual turn, rather than an abrupt one, your product will flow much smoother. Next, we will enquire about the type of container your media is being conveyed from, and to. Example, it is going from a super sack, to the dumpster, or from a drum to a hopper.

Next, we need to have an accurate bulk density, or pounds per cubic feet (or kg/m3). If this is unknown, we can easily find this by putting your product in a container and weigh it. We simply multiply the Length x Width x Height of the container, and divide that by the weight. This will give us the pounds per cubic foot. Finally, we need to know how many pounds per minute do you need to have conveyed.

With the above information in hand, please reach out and discuss your data with myself, or any of the application engineers to determine the Line Vac that is perfect for your application.
