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.

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.

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.

Light Duty Line Vac For Paper Trim Removal

Today I worked with a customer that manufactures a wide variety of material handling equipment including coil unwinders.  The engineer was calling because there was a special project for a coil unwinder that could handle a waste piece of paper trim.  As the metal coil is being unwound for delivery to a metal processing machine, the protective paper is pulled off and was to be collected into a waste receptacle for easy handling and disposal/recycling.  The engineer was hoping to replicate an existing system that used a hybrid blower system, with an extra compressed air nozzle, but in a simpler form.

Coil Unwinder

We proposed the use of the 4″ Light Duty Line Vac– shown below.130400The Light Duty Line Vacs offer an effective way to convey small and light materials a short distance. Like the standard Line Vac, the Light Duty Line Vac converts an ordinary hose or tube into a  conveyor for scrap, trim, and bulk materials.

When the process involves moving low volumes of materials over short distances, the Light Duty Line Vac is a great choice. The simplified (2) piece design offers effective conveying at a lower cost. As an added plus, the compressed air consumption is lowered to levels commensurate with handling the lighter materials, at lower volumes and short distances.  Using a pressure regulator to control the supply air allows for tuning of the transfer rate, and keeps air usage to the minimum amount needed.

The Light Duty Line Vacs are available with inlet/outlet diameters from 3/4″ up to 6″.  With no moving parts, maintenance free operation is assured.

When Efficiency And Practicality Collide

Even if you’re a casual reader of our blogs, you already know that EXAIR Application Engineers LOVE to preach efficiency in the use of compressed air…it’s our “bread and butter;” the very nature of our business. This year, we’re celebrating thirty-five years of leading the way in the development of efficient, safe, and quiet compressed air products. Our track record of success as a solutions provider across a diverse range of industrial and commercial applications is well documented in our blogs, as well as Knowledge Base and Case Study Libraries.  We devote considerable resources (engineering, research & development, product testing, etc.) to making certain that EXAIR Intelligent Compressed Air Products cost less to operate, and perform better, than whatever you’re using right now.

Strange as it may seem, though, sometimes our products are EXTREMELY popular in cases where they INCREASE a facility’s consumption of compressed air…by replacing something that DOESN’T use compressed air at all:

*I’ve written before about how our Large Maximum Cold Temperature Vortex Tubes have replaced liquid nitrogen rigs in freeze sealing operations.  Now, a Vortex Tube directs a portion of its air supply to (usually) unusable hot exhaust, in order to generate the usable flow of cold air.  When compared to the costs of liquid nitrogen and the resources involved to get it where it needs to be, though, the cost of the compressed air needed to operate the Vortex Tube is indeed the practical solution.

A 1/4 ton of refrigeration from a product that fits in the palm of your hand, and all you need is a supply or compressed air!

*Line Vacs are probably THE prime example of the value of using compressed air where it wasn’t used before…replacing a “bucket and ladder” operation:

Straight from our Catalog, a perfect example of using valuable compressed air to save even more valuable resources.

*Then there are the situations that just come down to time.  In large spaces, our Super Blast Safety Air Guns can be used to “sweep” the floor in a fraction of the time it takes an operator with a push broom.

Super Blast Safety Air Gun makes short work of large area cleanup.

To make a long story just a little bit longer…if you’re using compressed air, you can use it better with EXAIR’s engineered compressed air products.  And there are plenty of practical applications where you’re not using compressed air right now too.  If you’d like to find out more about either one, give me a call.

Line Vac – Air Operated Conveyors

Convey parts, materials, and waste – with no moving parts!

The Line Vac is a fast, low cost way to convey pellets, scrap trim, textiles, bulk solids, food products, chips, and much more.  Simply connect to a standard hose, tube, or pipe and a powerful in-line conveyor is created.

Available in (4) materials – aluminum, 303 and 316 stainless steels, and a special hardened alloy, and (3) end connection types – NPT threaded, smooth bore, and the new sanitary flanged. Sizes range from 3/8″ up to a 6″. It is certain that an available Line Vac option will meet your process criteria.

For lighter materials and short conveyance distances, the Light Duty model is ideal, and for the most abrasive and heaviest materials over longer distances, the Heavy Duty style is available.

The Line Vacs offer many safety benefits, including eliminating the dangers of lifting heavy sacks and climbing ladders to fill hoppers, and with the 316 stainless steel sanitary flanged Line Vacs, food materials are kept enclosed and and separated and provides ease of cleaning.

The Line Vac works by having a small amount of compressed air injected through directed nozzles to produce a vacuum on one end and high output air flow on the other, with instantaneous response.  By using a pressure regulator, available as part of a kit or separately, the flow of the material transfer can be easily controlled. No moving parts or electricity assures maintenance free operation!

Conveyance rates are determined by the material bulk density, typical particle size, total distance of conveyance, including vertical rise, and the targeted transfer rate.  An EXAIR Application Engineer can assist you, and with the above information, recommend the right size and type of Line Vac to meet the desired results.

All catalog models are in stock and we ship same day with an order received by 3 pm EDT in the US and 2 pm EDT for orders shipping to Canada.

Our team of engineers can design a special Line Vac to meet many applications special requirements, from special materials such as PVC and PVDF to special end connections such as pipe flanges and barbed hose connections.  Let us know the special requirements of your process and we’ll design a solution.

Don’t Throw the Baby Out With The Bath Water – and How it Applies to Manufacturing

There are many curious sayings from history that are still part of our vernacular, and whose origins are debated.  Examples are ‘Spill the Beans’ and ‘Bite the Bullet.’  One of my first supervisors liked to use the expression ‘Don’t throw the baby out with the bath water.’  Initially, I didn’t quite understand what was meant by this, and then wasn’t sure it was relevant in some instances.  Fast forward many years, I hadn’t thought too much about it, but for some reason, the phrase recently came back into my thinking.

Today the phrase generally means not to get rid of something good when getting rid of something bad (when throwing out the dirty bath water, you don’t want to throw out the baby, too!)  As I look back to the supervisor that used it, it was for situations where the solution was within grasp, but due to recent shortcomings it may seemed out of reach. Scrapping the whole thing (the baby and the bathwater) and trying something new would not be the favorable way to proceed.

I remembered this phrase when recently a customer called in about the 3″ Line Vac they were using.  It was performing OK, but just was’t doing what they had hoped. They asked if it was still returnable under the 30 day guarantee (it was) and how to start the return process.

EXAIR Line Vac Family

While we aim to make the return procedure simple and efficient, we will most likely ask a few questions.  We’ll ask ‘what are trying to do?’  ‘Can you send in any photos of the installation’ (we solve lots of issues by seeing something that can be easily remedied) and certainly we will ask ‘about the compressed air supply.’ In the recent customer call, the customer was trying to convey dog food, a distance of 25′ vertical and 18′ horizontal –  a fairly challenging distance, but not impossible.  A photo could be sent in if needed and then the discussion turned to the compressed air supply.  It was determined that the compressed air supply line was undersized for the 68.5 SCFM of 80 PSIG compressed air needed to for the Line Vac to operate to its full capability.  We reviewed the Installation and Maintenance Guide and suggested the proper pipe and air hose sizing for this installation. Armed with this new knowledge, the customer set about to modify the installation.

I got an email later that day from the customer.  Results were dramatically improved! Average of first measured trials yielded 50 lbs of material in 46 seconds, one of the fastest conveyance rates recorded for those types of distances. Customer was pleased and was looking forward to keeping the unit and getting the benefit that was expected.

In this case, the baby was not thrown out with the bath water.

To discuss your application and how an EXAIR Intelligent Compressed Air Product can be a benefit at your facility, feel free to contact EXAIR and myself or one of our other Application Engineers can help you determine the best solution.
