Family of Heavy Duty Threaded Line Vacs

EXAIR’s line of Heavy Duty Line Vacs are our most powerful of our pneumatic conveyors. It is very similar to our standard Lind Vacs, but the generator holes have been drilled out to boost the performance. You can also modify a standard Line Vac to match the performance of a Heavy Duty. We have a great video here that shows you exactly how. In addition to an increased performance, the Heavy Duty Line Vac is constructed of a hardened alloy steel that helps to prevent premature wear that can occur when conveying abrasive media.

I recently worked with a customer that had a Clean Sweep vacuum that they had purchased and were experiencing premature wear on the conveyor that was installed on the system. They were using it to reclaim blasting media that they use for several of their processes in the facility. The conveyor that was installed in the Clean Sweep vacuum system was constructed of aluminum and was quickly wearing out. By the time they found EXAIR, they had already replaced this unit twice and were getting close to needing a third replacement. A quick search of the internet brought him to our blog page where he saw this blog post about the Heavy Duty Line Vac. A quick review of the drawing for the vacuum system and we were able to identify that a 2” Model 151200 Heavy Duty Threaded Line Vac would match up perfectly and allow for a quick and easy installation. They have a total of (3) of these systems in their warehouse and wanted to try one out first. Once the warehouse manager returned from vacation he intended to purchase another two to replace the other units before they too wore out. The operators were pretty pleased at the boosted performance that the Heavy Duty Line Vac offered, and management was pleased that they no longer have to worry about one of their vacuum systems wearing out. Another satisfied customer!

If you have a vacuum application with abrasive or harsh media, give EXAIR a call. Our team of Application Engineers is standing by ready to recommend the best solution for your application.

PrACTice Like A Champion

If you follow our blog, you know that over the past 2 years I have posted a few blogs related to coaching my oldest son’s youth football team. Well it’s that time of year again as we enter our 3rd season with the team. Each year, the athletic boosters put together a “Spirit Wear” package for the players, parents and coaches to purchase that typically includes a t-shirt, with some type of motivational message, and matching shorts. Last year the slogan was “Out Work, Out Hustle, Out Hit”, and in all honesty, I really didn’t like it all that much. This year’s shirts have the motto “PrACTice Like A Champion” which plays right into the mentality our coaching staff tries to instill in our young players.

The head coach and I attended a youth football coaching clinic over the winter that was put on by our local NFL team, the Cincinnati Bengals, to further develop skills to help our players. During the clinic, one particular NFL positions coach used the term I.M.P.A.C.T. as an acronym for “I Might Provide A Critical Thought, Teaching or Technique”. This message really hit home for us with not only how we communicate with our players but also how we interact with each other, referees, parents, opposing coaches and players, etc. We are dealing with 8-9 year old kids who are very impressionable so how they see their leaders (coaches) act can play a large role in their own behavior.

Over and over we remind the kids during practice and in games that win or lose, we are going to respect the game and play it the right way. Too many times you see professional and sometimes collegiate athletic teams disrespect their respective sport by cheating or playing “dirty” to try and gain a competitive edge. Heck, during some of our own peewee games we’ve had opposing players get frustrated and try to take out key players or have coaches instruct their players to take a cheap shot after a play has been whistled dead. Now, I’m as competitive of a person as there is, but I will NEVER understand this type of mindset. These are young kids, playing a GAME. At the end of the day, you put your uniform on, line up and let the game play itself out – may the best team win. For our team, this year’s motto “PrACTice Like A Champion”, we hope is going to serve more purpose than just relating to our football program but rather as a way they go about each day.

While we don’t compete in sports at EXAIR, we do put in the “Practice” behind the scenes in being “Champions” to our industry. We are constantly working on developing new products to support our customer’s ever changing needs. For example, we recently released our NEW Catalog 31 which features several new products like our VariBlast Safety Air Guns, Sanitary Flanged Line Vac Air Operated Conveyors and our NEW Gen4 Static Eliminators.

Pneumatically Conveying Corn Flakes From Large Sacks Using An EXAIR Line Vac

This workspace needs a pneumatic conveyance solution.

I’ve had a string of great Line Vac applications which I’ve been able to write about recently.  Using our Heavy Duty Line Vac to convey small particles, vacuuming alumina dust two applications in the same plant, and removing chips from a plastic CNC router.  But, the application for this blog is a bit different because it involved conveyance of a material to prevent worker fatigue.

Dried corn flakes in super sack.

The dried flakes shown above needed a reliable method to convey between the large sacks in which they’re delivered and the boilers into which they need to be added.  The existing operation has been to have personnel cut open the bags and pour them into the boilers, but this method is taxing for the workers and results in significant fatigue throughout the day as well as spillage around the boilers.  This facility needed a better way to move the corn flakes that was small enough to fit within the confined workspace and capable of quickly emptying the sacks over a distance of ~6.5 ft.

The corn flakes need to be conveyed from the sacks on the right to the boilers on the left.

This customer requested that the solution be made of 316 grade stainless steel, and that implementation and use be as simple as possible.  With a bulk density of ~40 pounds/cubic foot, and merely a desire to move the material as fast as possible over this short distance, I directed them toward our 3” Stainless Steel Line Vac made of 316SS.  To increase the conveyance in the application I also offered our service to convert our standard model 6066-316 Line Vac to a “High Power” unit by increasing the size of the generator holes.

Both of these solutions were deemed as viable because they both allow for fast emptying of the bags (we estimated between 1-2 minutes to completely empty a bag), little-to-no spillage, and far, far less fatigue on the workers in this area (the key driver for searching out a new method of material transfer.

The potential model numbers were presented to management for a purchasing decision.  As this project moves forward, and even after the solution is installed, we’ll be available for product assistance and engineering support.  If you have an application in need of a viable pneumatic conveyor, contact EXAIR.  We’ll be happy to explore the application and offer any potential solutions.

Moving Small Particles with a Heavy Duty Line Vac

The material in this hose is conveyed vertically over 7m using an EXAIR Heavy Duty Line Vac

The image above shows a test at a customer’s facility to move a small particulate to a height of 7m (23’) with an EXAIR Line Vac.  This particulate is used in the production of hand warmers and the end user needed a method to convey the material out of 55 gallon drums.

This same customer purchased a 2” Heavy Duty Line Vac from EXAIR in 2014 which is still in use and functioning well.  So, when it came time to find a pneumatic conveyance solution for this material, they knew where to go.

This is the material which needed to be pneumatically conveyed.

And, we knew just the questions to ask to determine the best Line Vac solution.  In order to do so, we had to determine the following:

  • Bulk density of the material
  • Size of the material
  • Conveyance height
  • Conveyance distance
  • Required conveyance rate
  • Available compressed air supply

Bulk density was rather low at 320kg/m³ (~20 pounds/ft³), with a particle size between 3-5mm (~1/8”-3/16”).  The conveyance height in this application was 5-7m (16.5-23ft.), with a distance of 1-2m (3.3-6.6ft) and a desired conveyance rate of over 4kg (8.8 pounds) per minute.

Testing with a 2″ Heavy Duty Line Vac

The customer ran a test with the 2” Line Vac they have on site and the results were excellent.  Their only question was whether they could achieve the needed conveyance with a smaller unit, thereby reducing compressed air consumption and operating cost of the application.

In this case the answer was clear that a smaller Line Vac could be used due to the low bulk density of the material.  By reducing the size of the Line Vac to 1”, or perhaps 1.5” we could reduce the compressed air consumption and still meet the required performance need.

EXAIR Line Vacs have, once again, brought a viable solution to this industrial facility.  If you have a similar application or would like to discuss pneumatic conveyance needs, contact an EXAIR Application Engineer.  We’ll be happy to help.

Identifying Which EXAIR Line Vac You Have

I’ve written in the past about how to identify an EXAIR part, specifically how to identify a Vortex Tube. I recently ran into a very similar situation, only this customer was having difficulty identifying a Line Vac that was installed on one of his machines. The Line Vac was installed to remove a small pin from their part and convey it out to a separate bin for disposal. Rather than purchasing an additional machine, they were trying to expand the line and build one themselves. They reached some difficulty when trying to identify the EXAIR part that was installed and reached out to us for help.

EXAIR Model 6079 Line Vac

Our Line Vacs come stock in (4) different materials of construction: aluminum, 303 stainless steel, 316 stainless steel, and for our Heavy Duty models a hardened alloy steel for abrasion resistance. The hardware used on the aluminum models is a black oxide screw whereas the others all have stainless steel hardware. Since his had black oxide hardware, it was easy to discern that this was in fact an aluminum Line Vac. To differentiate between the 303 and 316 models, we make a small cut around the circumference of the part. The outer appearance of the Heavy Duty is easily distinguishable.

Once we’ve identified the material of construction we must measure the O.D. of the inlet and outlet. By cross-referencing this measurement with the dimensions in our catalog you can then identify exactly which model number Line Vac that you have. In this scenario, the customer had to remove the Line Vac from the machine to measure the O.D. of the cap. The manufacturer of the machine had turned down the outside of the outlet on the body. Fortunately, he sent us a photo which clearly showed that this was the case. Based on his measurement, I determined that he had an EXAIR Model 6079 that had been modified. He was able to immediately place an order for the replacement and it shipped that day!

If you have an EXAIR part somewhere in your facility that you’re struggling to identify, give an Application Engineer a call. Through a series of investigative questions (and hopefully the help of photos!) we’ll be able to determine the model number that you have and clear up any uncertainty.

Line Vac Brings Additional Solution To Alumina Spill Recovery

Mobile spill recovery unit

In my last blog post I wrote about vacuuming alumina dust in an aluminum manufacturing plant in South America.  In that application we were returning spilled alumina to the original hopper so that processing could continue.

This same customer has an additional application to vacuum spilled material, but the new need is to assist mobile spill recovery vehicles (shown above) in vacuuming spills of varying volume. These mobile vehicles are effective for most of the spillage demands they can access, but there are times where additional vacuum is needed, such as when the spill location is beyond the hose length of the system.  In those scenarios additional vacuum hose can be added, but line losses render the performance too low to produce real results.  With this in mind, the end user looked for a point-of-use vacuum boosting solution, and thought about again using an EXAIR Line Vac.

Considering the potential use of a Line Vac, we approached this in the same way as any other pneumatic conveying application, gathering the required information to allow a proper model number selection.  As with the previous application we confirmed the following:

  •      Bulk density of the material
  •      Size of the material
  •      Conveyance height
  •      Conveyance distance
  •      Required conveyance rate
  •      Available compressed air supply

The spills in this facility are comprised of alumina dust with a bulk density of 1.1g/cm³ (68.7 pounds/ft³).  From the floor to the maximum height of the vehicle is a distance of 3.25m (~11ft), and conveying distances were in a range of 3-10 meters (10-30 feet).  The customer had no required conveyance rate, only a requirement to boost vacuuming capacity when needed.

With this information confirmed we were able to make a model number recommendation, the 2″ Heavy Duty Line Vac model 150200.  Adding the 150200 Heavy Duty Line Vac to this mobile spill recovery unit brings additional vacuum flow and conveyance of the alumina through a high velocity airstream, making mobile spill recovery efforts more effective.

If you’re in need of a pneumatic conveying solution, contact an EXAIR Application Engineer (1-800-903-9247).  We’ll be happy to help.

EXAIR Line Vac, Air Operated Conveyors, Expand to Include Sanitary Flange Models

EXAIR’s Air Operated Conveyor product line just expanded, making it easier than ever for a wide range of industries to solve an ever growing range of bulk conveyance applications. Before we get to that, let’s look at just how versatile the Line Vacs are:

The standard Line Vac has been making bulk conveyance as easy as it could get for years now. They come in sizes from 3/8″ to 5″, and all you need is a hose to move material from point A to point B.

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.

When rigid pipe is preferable to hose, our Threaded Line Vacs offer the same performance:

These come with male NPT threads from 3/8″ to 3″. They’re also available in aluminum, 303SS and 316SS, and High Temperature versions, same as the standard Line Vac.

If you need high power for higher conveyance rates, longer distances, or very dense material, the Heavy Duty Line Vacs are what you’re looking for.

They come in sizes from 3/4″ to 3″, with options for slip-on hose or threaded pipe. They’re also made of a hardened alloy for superior abrasion resistance.

Light Duty Line Vacs are aimed at applications implied by the name…when smaller volumes of low density material don’t require all the head & flow generated by the standard or Heavy Duty models, these are as quick & convenient as the rest, and come in sizes from 3/4″ to 6″.

They’re also ideal when fragile parts might be subject to damage in the high velocity, turbulent air flow produced by the other models.

The newest additions to the Line Vac family are the Type 316 Stainless Steel Sanitary Flange models:

Also known as Tri-Clamp or Tri Clover, these connectors have a variety of advantages beneficial to certain industries: Quick to make up & take apart. No nooks or crevices, so they’re easy to clean. Wide variety of fittings, pipe and tubing are readily available.

These are especially popular in pharmaceutical, food, and brewing applications.

If you’d like to find out more about how to move bulk product quickly, easily, safely, and cleanly, give me a call.
