Heavy-Duty Line Vac Air Operated Conveyors Climbing to New Heights

During this COVID-19 shelter in place circumstance, as an avid outdoors man (specifically I do a lot of rock climbing), things have been frustrating to say the least. In the Cincinnati area with all the climbing gyms closed down climbers are flocking to their local crag to get that last climb in for the foreseeable future. My local crag is Red River Gorge in Rodgers, KY. As the climbing season has now ended due to this pandemic the season of indoor (aka at home) training has began to ramp up with everyone hitting their hang boards and starting harder work out routines in their free time. It came to my mind that now is the time to also check out my old gear and see what needs to be replaced.

Climbing gear needs to be strong, durable and light weight so that the gear does not fail you in your time of need. If properly set up, a climbing rated carabiner can withstand a force of 24 kN or 5395 lbs. Every bit of climbing material needs to be taken care of and replaced when the time comes. When your life is hanging by the gear that you use durability and maintenance is the difference from dropping or not dropping from a cliff. But climbing equipment isn’t the only thing that you want to be strong and durable; you also want your material handling equipment as well.

At EXAIR we strive to make strong, durable, and maintenance free compressed air products. One such product is our Heavy Duty Line Vac air operated conveyor; the Heavy Duty Line Vac is a stronger and more durable version of the standard aluminum Line Vacs. The body and cap of the Heavy Duty Line Vac is made out of a hardened alloy which provides abrasion resistance. This means that it can withstand materials such as sand, salts, steel shavings, tumbling and blast media, etc. They are available from 3/4″ through 3″ and are used with identical sized hose, tube or pipe. 

Heavy Duty Line Vac

The Heavy Duty Line Vac is also designed to lift heavier material and move it farther and/or higher. Materials such as steel shot, garnet and ground glass are common. More power also increases the distance materials can be conveyed. Heavy Duty Line Vacs convey 6 times farther than standard Line Vacs.

The Heavy Duty Line Vac also comes with either smooth connections or threaded connections. The smooth connections allow for our reinforced PVC conveyance hose to attach to the ends using a standard hose clamp. If a flexible hose is not appropriate for your application the threaded connections allow the line vac to connect to a hard pipe. Both types of connections are interchangeable to fit your conveyance needs.

If you have questions about our Heavy Duty 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.

Air Operated Conveyors for a Multitude of Jobs

With 119 distinct Models, EXAIR Line Vacs are used to convey everything from down feather to steel shot.  They’re versatile, reliable, durable, and incredibly easy to install and operate. Most applications can be completed using one of our many stock Line Vacs. Additional applications include part transfer, waste or trim removal, hopper loading, filling operations, chip removal and fiber tensioning.

line vac family
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.

They are available from 3/8″ to 5″ diameters, for use with hose, tube or pipe. Line VAcs have smooth ends for hose or tube. The threaded models use NPT threads from 3/8 NPT to 3 NPT to turn ordinary pipe into an air conveyor! They can also be bought with sanitary flange ends for easy disassembly when necessary for cleaning or maintenance.

Materials include aluminum, Type 303 and Type 316 stainless steel or a hardened steel alloy for moving abrasive materials like garnet, glass, or blasting media.

With that being said, there are always applications that need a special product. And because of that we do make “special” or custom products when the need arises.

Special PVDF Line Vac

For example this Live Vac has the sanitary flange design, but the customer needed it made from a special material so their product passing through it wouldn’t be contaminated by metal. So we did just that, we designed built and shipped this line vac and it worked amazingly well!

Accessories include the transport hose, mounting brackets, filter and regulators.  A filtering drum cover is very useful to keep material and/or dust inside, when transporting materials into a drum.

No matter what kind of bulk material you need to move, or what type of special conditions you have. EXAIR has a Line Vac product for it.  If you’d like to find out more, give me a call.

EXAIR Line Vacs: Dozens Of Models; Endless Applications

With 119 distinct Models, EXAIR Line Vacs are used to convey everything from down feather to steel shot.  They’re versatile, reliable, durable, and incredibly easy to install and operate.  Consider this list of uses, starting with our smallest Line Vac, and going to our largest:

  • Model 6058 3/8″ Stainless Steel Line Vacs pull mica from a bulk container and spray it into a mold for making decorative stones, to apply a glittery surface.  They used to do it by hand, but the Line Vacs spread it more consistently.
  • A Model 6079 1/2″ Aluminum Line Vac pulls small metal scraps from a metal trimming operation, as they’re cut, keeping the work area clean.
  • Model 130075 3/4″ Light Duty Line Vacs perform a similar function in a plastic cutting machine, conveying away cut chips and eliminating the need for periodically stopping the machine to clean up.
  • A medical device manufacturer saw a 50% increase in productivity when they went from removing flash by hand from molded silicon parts to using a Model 6061 1″ Stainless Steel Line Vac to suction it away automatically.
  • A mining equipment manufacturer reclaims sand from a secondary operation on their green sand molds with a Model 6062 1-1/4″ Stainless Steel Line Vac.  This keeps their mold area clean, and has eliminated waste in production.
  • Model 140125 1-1/4 MNPT Aluminum Threaded Line Vacs eliminated a  “bucket and ladder” operation where cotton seeds needed to be loaded into 7-foot high hoppers.
  • Model 151150 1-1/2 MNPT Heavy Duty Threaded Line Vacs, fitted into black iron pipe systems, reclaim hot metal chips from a deep channel milling machine, automating the transfer to the recycling hopper.  This eliminated the risk of lifting AND burn injuries from the manual handling of the hot chips.
  • Model 6084 2″ Aluminum Line Vacs vacuum trim scrap from custom label making machines to a central scrap bin, keeping the floor clean, and keeping operators from having to empty individual bins at each machine.
  • A Model 6065 2-1/2″ Stainless Steel Line Vac conveys rejected peanuts (identified and segregated by a vision sorting machine) from the catch pan to a large collection hopper.  This is hauled away at the end of each shift, instead of an operator paying constant attention to the catch pan.
  • Model 161300-316 3″ Sanitary Flange Line Vacs replaced mechanical conveyors in a grain mill, incorporating a totally enclosed Clean In Place (CIP) system.  This greatly reduced contamination controls when the product was openly conveyed, and actually increased their conveyance rates of their bulk grains.
  • A Model 6087 4″ Aluminum Line Vac conveys an additive (in pellet form) into an asphalt mixer, replacing an auger conveyor that left product in the hopper and would clog regularly, resulting in messy spills.
  • A company that recycles spent ammo from gun ranges uses a Model 6088 5″ Aluminum Line Vac to convey the granulated rubber backstop material into their truck.  After the ammo is separated, they use the Line Vac to replenish the granulated rubber into the backstop.
  • A Model 130600 6″ Light Duty Line Vac conveys linen squares (mostly 12″ and 24″ square) through the main header of a sorting operation in a commercial laundry facility.  The system also incorporates several Model 120024 4″ Super Air Amplifiers in individual “pickup” branches.

The EXAIR Line Vac is a fast, low cost way to convey most any bulk material.

No matter what kind of bulk material you need to move, EXAIR has a Line Vac product for it.  If you’d like to find out more, give me a call.

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.
