Models from 3/8″ to 3″ NPT are available in aluminum, type 303 stainless steel, and type 316 stainless steel. EXAIR also offers two Threaded Line Vacs for the most extreme conditions, High Temperature and a Heavy Duty Threaded Line Vac.
High Temperature threaded Line Vacs are made of stainless steel and can operate in temperatures up to 900°F.
htlvHeavy Duty Threaded Line Vacs are for those processes requiring the highest rates of conveyance over the longest distances and/or the most abrasive of materials. 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.

To select the right model, information regarding these criteria are helpful-
• Size of parts and bulk density of material being conveyed
• What size hose, tube, or pipe is desired
• Target conveyance rate
• Distance of conveyance, both horizontal and vertical legs
• Preferred material of construction

Conveyance Testing? We Can Do That!

Over the past month I have spoken with many customers who all had a similar concern.  Will the Line Vac actually convey my product?  Generally, the Application Engineer team can pool our experience together and get a pretty good feeling on if the product will be able to be conveyed the needed vertical and horizontal distance.  We can even give some estimates on what rate of transfer for the product.

In some cases though, the customer prefers to have some hard evidence to showcase to their leadership that the product will work and fill the need they have.  In those cases, as long as the product does not present a disposal hazard or respiratory hazard then we can probably take a small sample and do some testing then provide images, and possibly even some video.

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.

We may not be able to set up the exact product path that your system will require, we can generally convey a simple vertical with some horizontal.  The list below gives just a few examples of the products we have tested:

  • paper scrap
  • medicine tablets
  • ground rubber
  • dry ice
  • seasoning/spices
  • die cut scraps
  • steel shot
  • tumbling media
  • candy bars (These were delicious, please send more!)
  • nutraceuticals
  • plastic caps
  • plastic parts
  • packing peanuts
  • coffee beans
  • adhesive backing paper
  • cat food additive
  • bolts
  • springs
  • Doo Hickeys (okay, maybe my daughters made me watch Little Mermaid recently.)
  • sand
  • nuts/seeds

The list could go on and on.  The point is, if you are questionable on how well a Line Vac would work with your product, don’t let that deter you from reaching out to us and speaking with an Application Engineer.   We’ve done lots of product testing, and we will all share our experiences with you.  Also, we have conveyed a Cincinnati-Style Chili 3-way.  You can see that in the archives under Will It Launch.

Line Vac Makes Golf Ball Testing More Efficient

Recently, we at EXAIR worked with a major player in the golf ball manufacturing world.  As an avid golfer myself, this was an application I could really get a ‘grip’ on and I had the ‘drive’ to propose a solution.

2788771906_6bf60ff265_z
Golf Ball Pyramids

The customer was involved in Research & Development, performing testing on the golf balls through robotic hitting, collection, and attribute measurement. The current set up involved the ball being hit, gravity collection into a PVC tube, and then an operator unhooking the tube, walking it over to and unloading the balls onto a rack, in the same order of hitting. The customer wanted to eliminate the manual task of the tube handling and have the balls delivered directly to the rack area.  The transfer would need to be 15′ vertically, then 15′ horizontally, before dropping down to table level.  A typical rate is only 5 balls per minute. This is a perfect application for the Line Vac, a compressed air operated conveyor.

EXAIR had previously tested golf ball conveyance, as seen in the Line Vac video below (at the 1:53 mark) where golf balls are conveyed 100′, at only 30 PSIG of supply pressure.

To present the best solution to customer, we had 2 dozen golf balls sent to us, and we set-up and simulated the actual conveyance conditions of 15′ vertical and 15′ horizontal travel. We found that the balls could be conveyed at only 20 PSIG of supply pressure, when presented one at a time. When the inlet was flooded with golf balls, simulating a worst case condition, the Line Vac was able to perform the conveyance at 60 PSIG. Operation at 80-100 PSIG is possible providing a operational safety factor.

The customer was impressed with the results and has implemented the model 6984 – 2″ Aluminum Line Vac Kit into the process, making the process more efficient.

We have a team of Application Engineers that are ready to review your process and application, and help to determine if an EXAIR Line Vac can convey your material at the distance and rate desired.  We may even have you send in small sample of the material, and we can set-up, test, and share the results with you.

If you have questions about Line Vacs, or would like to talk about any of the EXAIR Intelligent Compressed Air® Products, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

Another Unique Application for an EXAIR Air Operated Conveyor

8261209385_4a37db3f1e_k
Plastic mesh used to protect parts prior to shipping

Generally, when we’re talking about a Line Vac application it involves the transfer of bulk materials from one place to another. Many applications involve replacing what we call a “bucket and ladder” operation. An operator must fill a bucket or container with the material, climb up a ladder, and then deposit it into a hopper. While this is a great example of one way to use  them, Line Vacs can also be used in a variety of other applications.

In the past, we’ve blogged about using smaller Line Vacs for conveying yarn or string. At the end of a run there’s often too little thread left on a roll to save for a future run. The customer must strip the yarn off the remaining spool in order to reuse it. Using just a small amount of compressed air, a 3/8” Line Vac makes quick work of any residual thread on the spool.

I recently worked with our distributor in Argentina on another unique Line Vac application. Their customer manufacturers a variety of different types of protective plastic mesh. They come in many different sizes and colors and are used to protect the outsides of parts or products during shipping. Their machine required an operator to keep a close eye and at times manually feed the material into the machine as it would get stuck. Their hopes were to automate this process so that they could increase production and alleviate the need for an operator to worry about feeding the material by hand.

Using a Model 6082 1-1/4” aluminum Line Vac fitted with a funnel on the intake side, they were able to convey the plastic material into the cutter. It was cut to length and deposited in a box below. The video below shows the process.

The material is fed off of the spool and into the cutter without jamming or getting bunched up. Production rates are now consistent and they were even able to increase the feed rate by almost 20%. The 6082 consumes just under 26 SCFM of compressed air at 80 PSIG, making it a low-cost solution to what was an aggravating problem for them. In addition to the ability to increase the feed rate, automating this process freed up an operator to monitor additional processes in the facility.

If you have an outside the box application that you believe could be suitable for a Line Vac Air Operated Conveyor, take advantage of EXAIR’s 30 Day Unconditional Guarantee and test one out for yourself!

EXAIR Heavy Duty Threaded Line Vac

EXAIR Threaded Line Vacs In Action!

EXAIR’s Heavy Duty Threaded Line Vac air operated conveyors can take ordinary threaded pipe and convert it into a powerful conveying system for pellets, scrap trim, bulk solids, chips, paper, small parts, sawdust, granules, and many other bulk materials. The Heavy Duty Threaded Line Vac attaches easily to plumbing pipe couplers, making it easy to build a complete system with parts that are readily available from your local home supply or hardware store.

They are available in 7 different sizes ranging from 3/8 NPT to 3 NPT and are made from a proprietary hardened alloy for superior abrasion resistance and performance. Heavy Duty Threaded Line Vac Air Conveyors are ideally suited for conveying large volumes of materials over long distances.  They eject a small amount of compressed air to produce a vacuum on the intake side and a high output flow from the outlet side.   Using a regulator to control the compressed air supply pressure, the rate of conveyance can be controlled to match what the application requires all while minimizing your compressed air usage!

The Heavy Duty Threaded Line Vac Kit includes a pressure regulator, filter separator to keep the air clean, modular coupler clamp (connects air regulator to filter separator, not shown below) and the mounting bracket for ease of installation.
