EXAIR Heavy Duty Threaded Line Vac

Published on by Leave a comment
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

Published on by Leave a comment

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.

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.

For other larger materials, higher transfer rates, corrosive environments, or abrasive materials, take a look at the other EXAIR Line Vac offerings including the aluminum, 303 and 316 stainless standard Line Vacs, the aluminum, 303 and 316 stainless steel Threaded Line Vacs, high temperature models, standard and threaded Heavy Duty Line Vacs, and lastly the new Sanitary Flanged 316 stainless steel type.

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

When Efficiency And Practicality Collide

Published on by Russ BowmanLeave a comment

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

Published on by Leave a comment

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.

To go with the Line Vac, we can provide a reinforced, heavy wall, clear PVC conveyance hose in lengths up to 50′.  Additionally, the Line Vac Drum Cover is a fine mesh, non-woven cover built to fit on the top of a 30 or 55 gallon drum.  It is designed to contain the material to the drum and allow the air from the Line Vac to escape.
