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.

Porous and Non-Porous E-Vac Vacuum Generators

Getting a vacuum from compressed air seems a bit like magic, but it works and it works well. EXAIR’s E-Vac® Vacuum Generators are compressed air powered, single stage vacuum generators. They are a low cost way to create vacuum for pick and place, clamping, lifting, chucking, vacuum forming and other applications.

The Low Vacuum Generators are ideal for ‘porous’ types of applications.  When we say ‘porous’ we are describing those processes where a lighter vacuum level combined with higher vacuum flows are needed. A good example of this is lifting a cardboard box. The cardboard is not air tight, and when you place a vacuum on it, air is able to be pulled through the cardboard. To maintain the vacuum level, the air needs to be able to be pulled through the cardboard and exhausted as fast as it is being pulled through in order to maintain the vacuum level. This requires higher vacuum flow and the design of the Low Vacuum Generator allows for the development of a good vacuum level and a high rate of vacuum flow.

The High Vacuum Generator is ideal for ‘non-porous’ type of applications. ‘Non-porous’ are those processes where the material is air tight, and no or very little air can pass through. Material such as glass, ceramic, and steel are ‘non-porous’. Because little or no air passes through, the need for high vacuum flow is not as important, and the highest of vacuum level can be achieved. A perfect vacuum is 29.92 in-Hg, and the High Vacuum Generator is designed to reach vacuum levels of 27 in-Hg, or a 90% vacuum level.

Both the Low Vacuum and High Vacuum Generators come in 7 different sizes, ranging from light to very strong vacuum capabilities, to match any application. Special Kits are  available as a way to experiment with an assortment of vacuum cups to determine the best configuration.

Vac-u-Gun: Low Cost Vacuum, Blowoff and Transfer

What is the Vac-u-Gun?  It is a low cost solution to many types of cleaning operations within an industrial setting.  The Vac-u-Gun is a vacuum gun, a blow gun, and a transfer tool, all-in-one! It is lightweight, easy to use, has durable die cast construction, and best of all, no moving parts to wear out. Simply hook up to a compressed air hose, and get to work.

Vac u Gun Hose

The Vac-u-Gun contains a nozzle insert that dictates the direction of air flow and operation. By simply unscrewing the the cap, reversing the orientation of the nozzle insert, and re-installing the cap, the gun is changed from a vacuum device to a blowoff device, and vice-versa.

The Vac-u-Gun can be used in three modes- Vacuum, Transfer and Blowoff-

Vacuum Mode – Vacuum shavings, absorbents, sawdust, or spills into a reusable bag, or into a receptacle via the vacuum hose. Why blow it off and the have to sweep it up later?

Transfer Mode – Transfer small parts, pellets, or trim over long distances, using the smooth bore vacuum hose.

Blowoff Mode – Blow chips, water, coolant, or scrap away from the work area. The large 1-1/4″ diameter outlet directs the air over a larger area in less time. The Vac-u-Gun uses less compressed air than an ordinary blow gun.

Vac-U-Gun Specifications

There are many advantages to a Vac-u-Gun, and some are:

Low cost, no moving parts/maintenance free, durable die cast construction, easy to switch form vacuum to blow mode, safe – no electricity, meets OSHA pressure requirements, lightweight and portable, versatile, and quiet.

Versatile!  In just seconds, the Vac-u-Gun can transform from a powerful, handheld vacuum tool into an efficient blow gun or transfer tool for lightweight materials. Each Vac-u-Gun System comes with the attachments needed to suit numerous industrial applications.

Three (3) Vac-u-Gun System options are available and shown below-

Vac-u-Gun System Options

All of the Systems include the Vac-u-Gun, brush, crevice tool, skimmer tool and (2) extension wands.

The Model 6192 Collection System also includes the reusable bag with clamp for debris collection.

The Model 6292 Transfer System also includes the vacuum hose, for transferring the debris to a collection point.

The Model 6392 All Purpose System also includes both the reusable bag and clamp and the transfer hose, providing the most versatility of all.

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.

Proper Air Supply Line Size Equals Proper Performance

Pipe_460top
Properly sized piping will allow your compressed air operated equipment to operate efficiently!

On any given day myself and my Application Engineering Brethren here at EXAIR have discussions with customers on air starvation of any given EXAIR Product.  The calls generally start off the same, “The Line Vac is not performing like it should”.  We at EXAIR absolutely want to help you get the most out of our products and we certainly want them to perform to your expectation.  However they must be supplied with clean/dry compressed air at sufficient pressure and volume.

Just the other day I was discussing a performance issue with a customer on a 1″ Line Vac.  The customer thought he needed a larger Line Vac.  I asked the questions regarding the diameter of his Supply Line and if he was using Quick Connect or Push Lock connectors.  He was attempting to feed this Line Vac with 1/4″ Poly Tubing through a elbow Push to Loc fitting.

This 1″ Line Vac was being severely starved for air and therefore not performing as expected.  The 1″ Line Vac require’s 14.7 SCFM @ 80PSI to reach the rated performance of 42″ of water column.

Below is a table for Pipe/Hose sizing from the Line Vac installation manual that you can use as a reference guide.  It is recommended that if using hose for the supply air to go up to the next size over the pipe recommendation.

Chart2

Don’t forget that quick connects and Push Lock fittings are not recommended and could restrict the air flow which will have a negative impact on performance.
