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.

Bulk Material Transfer Made Simple: EXAIR’s Threaded Line Vacs

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 an 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, it’s 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.

EXAIR’s Sanitary Flange Line Vacs: An Overview

EXAIR’s Sanitary Flange Line Vac is the ideal solution for customers looking to convey bulk materials in food & pharmaceutical applications (among others). Operating in the same manner as EXAIR’s smooth and NPT threaded Line Vacs, the Sanitary Flange Line Vac is available in (4) common flange sizes: 1-1/2”, 2”, 2-1/2”, and 3”.  All of EXAIR’s Sanitary Flange Line Vacs are constructed of Type 316 Stainless Steel for superior corrosion resistance.

There are different styles of flanges in industry. The Sanitary Flange Line Vac has been designed according to the flange standard outlined in ISO 2852. This standard was prepared by Technical Committee ISO/TC 5, Ferrous metal pipes and metallic fittings, Sub-Committee SC 1, Steel tubes. This is the second edition that replaces the first edition (ISO 2852:1974). The standard specifies the dimensions, tolerances, surface roughness, materials, assembling, and the hygienic requirements for the flange. These styles of flange are intended to be used with stainless steel tubes, specified in ISO 2037. ISO 2852 is considered an international standard, defining the connections used for non-permanent food-grade piping systems used within the pharmaceutical, food processing, dairy and agricultural industries.

In these industries, it’s required for the components to be thoroughly cleaned and sanitized. Using this type of connector, components within the piping system can be easily removed, sanitized, and then reassembled. A lipped flange with a grooved indentation is on each end of the pipe or Line Vac. A sealing gasket is then placed in between each section of pipe. A raised groove on either end allows it to seat onto the mating end of each flange. A clamp is then placed on the outside, forcing the sections together and compressing the gasket, creating an air-tight seal.

If your processes currently utilize sanitary flange piping, EXAIR’s Sanitary Flange Line Vac is the ideal solution to help you convey bulk materials from one point to another quickly, safely, and efficiently. If you have interest to test one out in your process, EXAIR offers an Unconditional 30 Day Guarantee on all stock items. They’re on the shelf now available to ship same day with an order placed by 2:00 ET!

EXAIR Line Vacs™: Air Operated Conveyor Promo

EXAIR Line Vacs

As an Application Engineer, I get the pleasure to speak to many companies about finding a simple, long-lasting, powerful and quiet type of transfer system.  Companies have operators that climb steps to dump bags of material into hoppers above.  This can be dangerous and is not ergonomic.  Other applications would include a compact way to remove scrap from a process; or budgetary constraints to convey material from point A to point B.  If your company has to tackle any of these issues, EXAIR can help you.  We manufacture Air Operated Conveyors that do not have any moving parts, very compact in design, and have a high throughput capacity.  They can attach easily to standard hoses, pipes, or sanitary flanges.   These inexpensive conveyors are designed to make conveyance safer and ergonomically better for your staff.  EXAIR calls this product line, Line Vacs™

Line Vacs can convey many things.

Line Vacs use a small amount of compressed air to generate a vacuum by a Venturi effect.  The unique design generates a high velocity to create a powerful vacuum on one side.  Once the product reaches the throat area of the Line Vac, the compressed air will carry the product the rest of the way.  We can reach horizontal distances up to 100 feet (30 meters) and vertical heights up to 20 feet (6 meters).  EXAIR manufactures a variety of Line Vacs in different sizes, styles, and materials.  Here is an overview of the Line Vacs that EXAIR offers.

Lightweight and durable aluminum is the most popular choice, but we make them in stainless steel (Types 303 and 316) for heat and corrosion resistance. For extreme heat, the High Temperature option affords protection to 900F (482C) in either 303SS or 316SS.

Line Vacs:  Our standard Line Vac is the most versatile product in this family.  We have two types of connections, slip-on ends for hose connections and threaded ends for pipe connection.  EXAIR can also mix the connection types on each end.  They range in diameters from 3/8” (10mm) up to 5” (127mm).  We manufacture the Line Vacs in aluminum, 303SS, and 316SS; but don’t let that deter you from asking for special types of materials.  We have a high temperature version that can withstand temperatures up to 900oF (482oC).  These Line Vacs work great in applications for loading plastic pellets in hoppers, discarding scrap pieces, trim removal, and transferring material.  If an operator has to place a bag of dry material on his shoulder to climb stairs, a Line Vac would be a much better alternative.

Heavy Duty Line Vac Family

Heavy Duty Line Vacs:  They 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 convey heavier materials at higher conveyance rates.  They can reach rates as high as 40 lbs./min. (18.2 Kg/min) of material.  With the hardened alloy construction, they are great for sand blasting materials, ceramic, glass 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.      

Light Duty Line Vacs

Light Duty Line Vacs:  On the other end of the Line-Vac spectrum, EXAIR created the Light Duty Line Vac.   They use much less compressed air than the other Line Vacs which is great for moving lightweight materials over short distances.  They can also be used for removing smoke and fumes from a work area.  The Light Duty Line Vac ranges from ¾” (19mm) up to 6” (152mm) diameter for slip-on hose connections.  This two-piece design provides an effective way of moving material at a lower cost.  It can be used in applications like hopper loading, fiber tensioning, filling operations, and smoke removal.   For moving material within a short distance, the Light Duty Line Vac could be the proper product to use. 

Sanitary Flange Line Vacs

Sanitary Flange Line Vacs:  Our latest engineering design within the Line Vac family is the Sanitary Flange Line Vacs.  They can convert pipes into a useful conveyor for bulk material and waste removal.  They use an ISO2852 flange for easy disassembly and cleaning to reduce bacterial entrapment.  They ae made from 316 stainless steel material for superior corrosion resistance.  They come in four different sizes to fit the sanitary flanges from 1 ½” up to a 3” flange.  For sensitive applications where cleanliness is a major requirement, the Sanitary Flange Line Vac are manufactured for these conditions. 

With all of the EXAIR Line Vacs above, they can be sold as kits.  A kit will include a filter, regulator and a bracket.  (Bracket are not sold with all types and sizes.)  The filter will help keep the Line Vac clean as well as the product that it being conveyed.  The regulator is a great tool to vary the conveyance rates for better control.  The bracket helps to mount the Line Vac to a sturdy base for support.      

If you need to convey solid materials in a quick and easy way, an EXAIR Line Vac could be a solution for you.  We have them in a variety of formats to match your application.  They are compact, quiet, and simple to use without any moving parts.  As compared to a conveying system which are bulky and rigid, the Line Vacs are flexible and inexpensive.  Ergonomically, they can save the back-wrenching labor of picking up bags, climbing stairs, and dumping material into hoppers.  For our U.S. and Canadian customers, we are running a promotional ad.  You will receive a 2” Flat Super Air Nozzle, a $75.00 value, for free from now until the end of October 2021 with a qualified purchase online.  If you would like to discuss your conveying application further, please contact an Application Engineer at EXAIR.  We may have the perfect solution for you.
