Heavy Duty Line Vac: A Powerful and Durable Pneumatic Conveyor

HDTHRlvFAMbg_500sq

EXAIR’s Line Vacs are an ideal solution for bulk conveying over long distances. With just a small amount of compressed air, the Line Vac generates vacuum on one end and high output flows on the other. The conveyance rate is easily adjustable by regulating the pressure supplied to the Line Vac. At higher input pressures the Line Vac will move more material, at lesser pressures the conveyance rate is also reduced.

The Heavy Duty Line Vac looks similar to the standard Line Vac, but packs a more powerful punch. Performance has been boosted with larger holes in the generator. This makes the Heavy Duty Line Vac ideal for heavier materials that must be conveyed over longer vertical and horizontal distances. Standard Line Vacs can also be drilled out to match the performance of a Heavy Duty. In addition to being a more powerful conveying system, the Heavy Duty Line Vac is also constructed of our proprietary hardened alloy steel blend. This material provides exceptionally strong abrasion resistance for applications requiring the transfer of materials such as crushed glass, steel shot, or dry sand.

Where a material such as aluminum or even stainless steel would quickly wear out, the Heavy Duty Line Vac will not. As with all of our stock products, the Heavy Duty Line Vac comes with EXAIR’s Built-To-Last 5 year warranty. We’ve tested these units here ourselves with a variety of different common abrasive materials. Check out the video below to see for yourself just how durable these Line Vacs are!

Just as the Standard Line Vacs, the Heavy Duty Line Vac can come with either smooth of NPT threaded connections to turn ordinary pipe into a powerful conveying system. With sizes from ¾ NPT up to 3” NPT, there’s a size from stock available suitable for your application. If you’re looking to move abrasive materials from one point to another in your shop, look no further than EXAIR’s Heavy Duty Line Vac. Reach out to an EXAIR Application Engineer for help in determining the most suitable sized Line Vac for your requirement.

Product Overview: EXAIR Line Vacs

Line Vacs can convey many things.

Do you have operators climbing steps to dump bags of material into hoppers?  Do you need a faster way to remove scrap from a process?  Do you have budgetary constraints in trying to move material from punt A to point B?  If you answered yes to any of these, EXAIR may have a simple solution.  We manufacture an air-operated conveyor that does not have any moving parts, has a very compact design, and generates a high throughput capacity.  They can attach easily to standard hoses, pipes, or sanitary flanges to convert your piping system into a powerful conveying system.   EXAIR manufactures these air-operated conveyors and trademarks them as Line Vacs™.

EXAIR Line Vacs use a small amount of compressed air to generate a powerful vacuum by a Venturi effect.  The unique design of the generator creates a high velocity of air to create a low pressure on one side and a powerful thrust on the other.  The Line Vac can pick up and move solid material from light and fluffy batting to steel components.  They can transfer product horizontally up to 100 feet (30 meters) away and vertically up to 20 feet (6 meters) high.  You can watch a video on the operation of a Line Vac HERE.  Compared to other vacuum or conveying systems, the EXAIR Line Vacs are very quiet, rugged, and powerful.  EXAIR makes a variety of Line Vacs in different sizes, styles, and materials to best fit your application.

 

The standard Line Vac is the most versatile product in this family.  EXAIR stocks a wide range of sizes, materials, and styles for targeting the best solution for moving material.  We have two types of connections, slip-on ends for hose connections and threaded ends for pipe connection.  EXAIR can swap the connections with a slip-on hose on one end with a threaded connection on the other.  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 if your need them manufactures in any other type of material.  We have high temperature models that can withstand temperatures up to 900 deg. F (482 deg. C).  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 carry a container of dry material and climb stairs, a Line Vac could be a much better alternative.

Heavy Duty Line Vac: Hardened Alloy Construction and High Performance

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 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 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.

EXAIR’s Light Duty Line Vac

On the other end of the Line-Vac spectrum, EXAIR also created the Light Duty Line Vac.   They use much less compressed air than the other Line Vacs which work 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.

Model 161200-316 – 316 Stainless Steel Sanitary Flange Line Vac

Our latest engineering design within the Line Vac family is the Sanitary Flange Line Vacs.  They can fit within sanitary piping systems to 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.  (A bracket is not sold with the Light Duty Line Vac kits.)  The filter will help keep the Line Vac clean as well as the product that it is conveying.  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.  A useful accessory to conveniently hide the compact Line Vac for ease of use and operation.

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 is 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.  If you want to know if the EXAIR Line Vac could work for you, please fill out the Line Vac Data Sheet (click HERE).  An Application Engineer at EXAIR will help to recommend the best unit for you.

Line Vacs- Air Operated Conveyors, and Much More

The EXAIR Line Vac is a tried and true device for conveying parts, materials, and waste – with no moving parts. The list of successfully conveyed materials in the application database is far reaching – including plastic pellets, scrap/trim, chips, pills/tablets, shavings, sawdust and granules.

The Line Vacs can be used for more than conveying large amounts of material from A to B. Recently, one of our automation customers found an application for the Line Vac in the design and manufacture of a custom fill machine.  The machine was commissioned to fill small, plastic cups.  To move the cups from the material staging area to the filler processing area, (10) of the 2″ aluminum Line Vacs were used.  Using a sensor to measure the stack height in each tube, the compressed air is triggered on/off to transfer a group of cups over to the filling area.  See photo below-

Threaded Line Vacs: Low Cost Conveyor Uses Ordinary Pipe!

EXAIR’s Threaded Line Vac air operated conveyor takes an ordinary pipe and converts it into a powerful conveying system.  A fast, low cost way to convey items such as pellets, scrap trim, bulk solids, chips, paper, small parts, sawdust, granules, and so much more. The Threaded Line Vac attached easily to plumbing pipe couplers, like PVC or iron, making it easy to build a complete system with parts readily available from your local supply house or hardware store.

The Threaded Line Vac are ideally suited for conveying large volumes of materials over long distances.  Like the standard, smooth bore ended Line Vacs, the unit works by ejecting a small amount of compressed air to produce a vacuum suction on the inlet side and a high output flow from the outlet side.  By using a pressure regulator to control the compressed air supply pressure, the rate of conveyance can be controlled to match the application needs, while minimizing the compressed air usage.

3inTrLVbckls_prHR1670x574

Models are available from 3/8 NPT to 3 NPT with materials of construction of aluminum and types 313 and 316 stainless steels (excellent corrosion resistance.)  High temperature versions of the stainless steel Threaded Line Vacs are available as well, for temperatures up to 900°F.

For those processes requiring the highest rates of conveyance over the longest distances and/or the most abrasive of materials, the Heavy Duty Threaded Line Vac is the right choice.  Designed with the most rugged industrial processes and applications in mind, the special hardened alloy construction helps prevent premature wear that could occur with standard aluminum or stainless steel models, under the harshest of conditions.  The performance has been boosted, to be able to convey more material, over longer distances and higher vertical rises.

Coast to Coast and Beyond

Recently, I was working with  a customer looking for a Premium Reversible Drum Vac and wanted it shipped to the Northwest Territories of Canada –  which we could do!  It got me to thinking, what are the farthest US state and territory locations EXAIR has shipped to in the North, South, West and East directions.  I ‘scoured’ the records and came up with these.

Furthest North- We have shipped to Prudhoe Bay, Alaska.  Most recently, believe it or not, we shipped a NEMA 4X Cabinet Cooler to an Oil and Natural Gas Exploration Company.  Goes to show that even the coldest environments still have the need to provide cool, clean, dry air to cool and protect electronics in electrical enclosures.

Furthest South – We have shipped to the US Territory of Puerto Rico, city of Santa Isabel.  An Aerospace company needed a strong, laminar blast of air and utilized a 6″ Stainless Steel Air Knife.  An Air Knife offers a quiet, efficient way to clean, dry or cool parts, webs, or conveyors.

Furthest West- We have shipped to the US Territory of Guam.  The local University ordered a model 1111-4 Super Air Nozzle Cluster, for a good strong blast of air flow for a cleaning operation.  The model 1111-4 delivers 3.2 lbs of force, at just 82 dBA of sound. A safe and efficient nozzle for blowoff operations.

Furthest East- We have shipped to Eastport, Maine.  The customer in Eastport ordered a Line Vac and a section of Conveyance Hose.  The Line Vac is a great tool for conveying large volumes of material over long distances, through a standard hose or tube.  The compact design features large throat diameters for maximum throughput capability.

 

It was interesting to look back and see all the places that EXAIR has shipped.  We have customers from all over the globe. If you are outside the of 50 US States and Canada, we have a dedicated team of International Application Engineers that will work with you to select the best EXAIR product for your process and application, and direct you to your local International Distributor.
