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.

Be sure to check out our promotion on Line Vacs as well.

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.

Line Vac Air Operated Conveyors: What to Know When Specifying

So you are thinking about using a Line Vac… Is it time to replace that ladder and bucket, and automate? There are many factors involved when deciding to use a conveyor system such as EXAIR Line Vacs. First of all let’s take a look at your product that needs conveyed. Will the integrity of your media be compromised by adding this much air to it? How heavy is it? What type of (how much) surface area does it have?

You know your media better than most. You should be able to answer most of those questions pretty easily, but what about the weight? For the weight, we work best knowing the bulk density, or pounds per cubic foot. If you do not readily know, this is easily found by finding the weight of your media in a box (or container). Then take the total cubic inches of the box (L x W x H) and divide that by 1728 (cubic inches per cubic foot), this will give you the cubic feet of that box. Then you simply divide the weight by the cubic feet, and you now have the density.

Line Vacs can convey many things.

Next we need to focus on your conveyance run. We would like to know what type of container is your product sitting in? A super sack, a hopper, a drum, a box? And where is it going? How far away is the destination hopper, dumpster, assembly station, etc.? This will help us determine the type of fitting or tools necessary to extract or release the media. How high do you need to go? How far horizontally? Our Line Vacs, are amazing, but they do have their limits. We will also need to know if there are any turns, and at what angles. Turns are many times unavoidable, but will have an adverse effect on the conveyance run as the airflow is halted and or deflected. Is there a way to minimize or eliminate the turns?

The final question is; how many pounds per minute do you need to be conveyed?

With the size, mass, and geometry of your parts, along with the vertical lift length, and the horizontal conveyance length, added to the turns and twists, you are just about ready to call one of our our application engineers for recommendations. We have some comparison materials for conveyance rates, to get you close to your actual needs. Here are some published conveyance rates as well:

There is one more part to this equation. What type and size of Line Vac will you need? EXAIR has many types of Line Vacs to choose from. As with most products, we have options that take into consideration the temperature and the abrasiveness of your product. We also have options to fit the type of conveyance hose or pipe you want to use , such as sanitary fittings, or threaded. And since we manufacture these right here in Cincinnati, OH, we can make custom Line Vacs for customers fairly quickly. We have designed and manufactured them with custom bolt on flanges, special materials or inlet sizes to name a few.

More And More Award Winning Products From EXAIR

As you might expect, a LOT of things have changed at EXAIR Corporation since 1983. Most of our current senior management had yet to graduate high school, and a fair number of current employees had yet to BE BORN. According to our computer system (another BIG change since 1983), our first ten customers were here in southwest Ohio (#11 was in Michigan), and now, we sell direct across the US & Canada, and our worldwide distributor network offers representation on six continents. One thing that hasn’t changed, though, is our founder’s vision of manufacturing quiet, safe, & efficient compressed air products for process improvement in just about any industry that uses compressed air. And THAT, dear reader, continues to gain high profile attention. The photo above shows the seven awards that our products have recently won, which were announced in 2021 or early 2022. Here’s a rundown:

Plant Engineering 2020 Product of the Year (Fluid Handling) GOLD AWARD:
1/2 NPT No Drip External Mix Air Atomizing Spray Nozzles

No Drip External Mix Atomizing Spray Nozzles

The 1/2 NPT models are the latest addition to our newest product line. The External Mix version offers the highest liquid flow rate, and largest pattern coverage. Among the applications where they’ve excelled so far are:

  • Snack food provider – applying flavoring to bulk snack materials.
  • Commercial bakery – spraying cooking oil onto pans used in a conveyor oven.
  • Sporting goods manufacturer – applying adhesive to the tops of skateboard decks to glue the grip tape on.

Plant Engineering 2020 Product of the Year (Material Handling Systems) GOLD AWARD:
2-1/2 NPT 303SS Threaded Line Vac

EXAIR's Threaded Line Vac Family
EXAIR Threaded Line Vac + Your Pipe + Compressed Air = Instant Conveyor System

For bulk material conveyance, it really doesn’t get any simpler than EXAIR Air Operated Conveyors. Stainless Steel models are especially popular when the environment – or the product – is corrosive, or hot…they’re good to 400F (204C), and can even be modified with High Temperature components for exposure up to 900F (482C). The Threaded versions have been successfully used to:

  • Recycle sprinkles applied to wafers into a return hopper in a candy production facility.
  • Replacing an auger conveyor to allow for homogenous mixing of grains & supplements in feed stock at an agricultural mill.
  • Providing a low cost solution to convey product into a hopper at a grain processing plant.

Occupational Health & Safety 2021 New Product of the Year (Industrial Hygiene-Dust Control) WINNER
Occupational Health & Safety 2021 New Product of the Year (Health & Safety/Cleanup) PLATINUM

EasySwitch® Wet-Dry Vac

Like our Spray Nozzles product line, our Industrial Housekeeping Products line has also grown considerably over the years. The Deep Hole Vac-u-Gun and Heavy Duty HEPA Vac were real game changers when they came along, and the EasySwitch® Wet-Dry Vac Systems are likewise making an impact. Switching from wet to dry operation is, as advertised in the name itself, INCREDIBLY easy. Among our satisfied customers are:

Occupational Health & Safety 2021 New Product of the Year (Lab Safety) WINNER
Intellistat® Ion Air Gun™

The newest innovation in a long line of EXAIR static elimination solutions, the Model 8500 Intellistat® Ion Air Gun is made for laboratories, clean rooms, medical & electronic applications, and carries an ISO 14644-1 Class 5 rating for clean room use. Because of their rapid decay rates and lightweight construction, they’re used in a diverse range of applications and areas, including:

  • A supplier of fiberoptic parts uses an Intellistat® to remove dust and static charge from product prior to packaging.
  • A medical device manufacturer has one in a Class 7 clean room for silicone parts cleanliness.
  • A nutritional supplements maker uses their Intellistat® to remove static charge & powder residue from the tops of plastic bags before sealing them. The excess/residual powder causes them not to seal correctly.

Machine Design 2021 Big Idea! (Electrical Components) BRONZE AWARD
Gen4® Static Eliminator Power Supply

All EXAIR Gen4 Static Eliminators use one of two Power Supplies – your choice of the 2-port Model 7960, or the 4-port Model 7961.

EXAIR Static Eliminators produce ionized air via a Corona discharge, which requires high voltage, low current electricity. The Gen4® Static Eliminator Products feature armored & shielded cables with an internal ground, for safety and reliability. The ground path is completed through the cable and the Power Supply port, eliminating the need for an external ground connection. Faults in external ground connections result in the majority of the problems with those devices, so the internal ground is a “Big Idea!” indeed. The Gen4® Static Eliminator Power Supplies are switchable for 115VAC or 230VAC voltages, and are offered in 2, or 4 outlet designs, which can power any 2, or 4 EXAIR Static Eliminator Products. Like most EXAIR Intelligent Compressed Air Products, they’re used for a wide range of applications, in a wide range of industries:

If you’d like to find out more about these, or any of our other engineered compressed air products (we’re pretty proud of them all), give me a call. I can talk about them all day long…and sometimes I do!
