EXAIR's Threaded Line Vac Family

Advantages of EXAIR’s Threaded Line Vacs

Published on by Jordan T ShouseLeave a comment

EXAIR Line Vacs use a small amount of compressed air to generate a powerful vacuum by a Venturi effect.  The unique design of the generator creates a high velocity of air to create a low pressure on one side and a powerful thrust on the other. The Line Vac can pick up and move solid material from light and fluffy batting to dense, heavy and abrasive material and parts.  They can transfer product horizontally up to 100 feet (30 meters) away and vertically up to 20 feet (6 meters) high.  You can watch a video on the operation of a Line Vac HERE.  Compared to other vacuum or conveying systems, the EXAIR Line Vacs are very quiet, rugged, and powerful. They are exceptionally simple to install and solve many “bucket and ladder”, loading and scrap removal applications. EXAIR manufactures a variety of Line Vacs in different sizes, styles, and materials to best fit your application.

The standard Line Vac is the most versatile product in this family.  EXAIR stocks a wide range of sizes, materials, and styles to target the best solution for moving material.  We have two types of connections, slip-on, hose barb type ends for hose connections and male NPT threaded ends for pipe connection.  EXAIR can swap the connections with a slip-on hose on one end with a threaded connection on the other.  They range in diameters from 3/8” (10mm) up to 5” (127mm).  We manufacture the Line Vacs in aluminum, 303SS, and 316SS; but don’t let that deter you if your need them manufactured in any other type of material.  We have high temperature models that can withstand temperatures up to 900 deg. F (482 deg. C).  These Line Vacs work great in applications for loading plastic pellets in hoppers, discarding scrap pieces, trim removal, and transferring material.  If an operator has to carry a container of dry material and climb stairs, a Line Vac could be a much better alternative.

EXAIR Corporation 3 NPT Heavy Duty Line Vac™ Conveys Plastic Cap Nails.

The Heavy Duty Line Vacs are made from a hardened alloy steel for abrasion resistance.  The generators inside these Line Vacs are more powerful than the standard models; so, that they can also convey heavier materials at higher conveyance rates.  They can reach rates as high as 40 lbs./min. (18.2Kg/min) of material.  With the hardened alloy construction, they are great for sand blasting applications, ceramic, glass and steel shot.  They are manufactured with inlet and outlet connections for ship-on hoses or threaded pipes.  EXAIR stocks the Heavy Duty Line Vacs in the range from ¾” (19mm) to 3” (76mm) for both hose and NPT connections.  These Line Vacs are our most powerful design with great wear resistance.

Both the Standard and Heavy Duty Line vacs can be offered as Threaded Line Vacs which converts the smooth OD for hose slip over to a Male NPT to connect common plumbing fittings to they are both available in a range of different materials: Aluminum, Type 303 Stainless Steel, Type 316 Stainless Steel, and as a Heavy Duty conveyor constructed of a proprietary hardened alloy steel for use in abrasive applications.

Each style of Threaded Line Vac is also available as a High Temperature option. By replacing the traditional o-rings with graphite seals, we’re able to provide a solution capable of withstanding temperatures up to 900 °F!!!

EXAIR Line Vacs are also sold in kit format.  A kit will include a filter, regulator and a bracket.  (A bracket is not sold with the Light Duty Line Vac kits.)  The filter will help keep the compressed air passages inside the Line Vac clean as well as the product that it is conveying.  The regulator is a great tool to increase and decrease pressure as needed to vary the conveyance rates for better control.  The mounting bracket allows the user to securely mount the Line Vac to a sturdy base for support.

What’s So Great About The New EXAIR Catalog #35?

Published on by Russ BowmanLeave a comment

This may seem biased, but my answer is, “EVERYTHING!” Now, that may SEEM biased, but consider the fact that, as an Application Engineer, I have a front row seat for the “Innovation Show” that is EXAIR. The attention to detail that gets paid to the design, testing, verification, and manufacturing of new products constantly reminds me that it’s a level of excellence that EXAIR’s founder, Roy Sweeney, instilled and promoted in our culture from when he started this business in 1983, until his passing in 2016. It’s a testament to his legacy that, not only does it continue; it shows no signs of slowing down. It’s that level of excellence that’s always made it easy for me to speak with confidence about the quality, performance, durability, and effectiveness of all of EXAIR’s engineered compressed air products.

Our Marketing folks proudly passed out copies of the new EXAIR Catalog #35 the other day, and I immediately started immersing myself in that pride as I thumbed through. I thought of 12 years (for me) worth of success stories in helping customers get the most out of their compressed air systems through the use of our products, and our expertise in not only those products’ implementation, but how they can best fit into those customers’ air systems, overall. I wasn’t too far in to my thumbing through, when the “new stuff” really started making an impression on me:

Ultrasonic Leak Detector: Model 9207 is the first new product you’ll see if you start at the beginning. It has the same functionality and tools (parabolic disc for finding out you have leaks in a particular area, and a tubular extension so you can track the leak to its exact location), and some nice upgrades: it’s powered by four AA batteries (instead of a 9V) and comes with a set of earbuds (which I personally prefer over the previous model’s earphones, which I always considered a compromise between headphone & earbuds, with the benefits of neither). It’s never been easier to find those costly leaks in your air system, and fix them.

1/2 NPT HollowStream Liquid Atomizing Spray Nozzles: We’ve had these in 1/4 and 3/8 NPT sizes for a while now, with the ability to spray up to 7.28 gallons per minute. The 1/2 NPT models almost double that capacity to a flow rate of 14 gallons per minute. These spray a ring of liquid, so their flow rates are lower than a comparably sized Full Stream Liquid Atomizing Spray Nozzle, which spray a full, filled-in circle.

Line Vac Conveyance Chart: Remember what I said above about the ability to speak confidently about our products? This new chart compiles decades of controlled in-house testing and details that some customers have shared with us on the performance of different Line Vac models with different materials they’ve been used to convey. While we can’t guarantee EXACT conveyance performance for any specific application, this is a VERY handy tool to get us “in the ballpark” and further increases our great ability to specify the right Air Operated Conveyor for your application.

ATEX Cabinet Cooler Systems: It was a pretty big deal when we introduced our HazLoc Cabinet Cooler Systems that are UL Classified for Class I Div 1, Class II Div 1, and Class III environments. And it WAS a big deal, in the United States & Canada. Now, we can offer the certification of hazardous location requirements, globally, for ATEX Zones 2 & 22. That’s ANOTHER big deal.

Speaking of big deals, come October, EXAIR will have been providing quiet, safe, and efficient compressed air products to industry for 40 years. Catalog 35 has all the products that we’ve been making since then, and everything we’ve added over the years. Click here to get one mailed out to you right away. If you’ve got questions about anything in our catalog, or how EXAIR can help you get the most out of your compressed air system, give me a call.

EXAIR has a Line Vac for your Application!

Published on by Jordan T ShouseLeave a comment

With countless number of different Models to fit every application, EXAIR Line Vacs are used to convey everything from the lightest of packing peanuts to heavy steel shot.  They’re versatile, reliable, durable, and incredibly easy to install and operate. 

Line Vacs are EXAIR’s current promotion too, see the offer here.

EXAIR Line Vacs use a small amount of compressed air to generate a powerful vacuum by a Venturi effect.  The unique design of the generator creates a high velocity of air to create a low pressure on one side and a powerful thrust on the other. The Line Vac can pick up and move solid material from light and fluffy batting to dense, heavy and abrasive material and pieces.  They can transfer product horizontally up to 100 feet (30 meters) away and vertically up to 20 feet (6 meters) high.  You can watch a video on the operation of a Line Vac HERE.  Compared to other vacuum or conveying systems, the EXAIR Line Vacs are very quiet, rugged, and powerful. They are exceptionally simple to install and solve many “bucket and ladder”, loading and scrap removal applications. EXAIR makes a variety of Line Vacs in different sizes, styles, and materials to best fit your application.

The standard Line Vac is the most versatile product in this family.  EXAIR stocks a wide range of sizes, materials, and styles for targeting the best solution for moving material.  We have two types of connections, slip-on ends for hose connections and threaded ends for pipe connection.  EXAIR can swap the connections with a slip-on hose on one end with a threaded connection on the other.  They range in diameters from 3/8” (10mm) up to 5” (127mm).  We manufacture the Line Vacs in aluminum, 303SS, and 316SS; but don’t let that deter you if your need them manufactured in any other type of material.  We have high temperature models that can withstand temperatures up to 900 deg.

C).  These Line Vacs work great in applications for loading plastic pellets in hoppers, discarding scrap pieces, trim removal, and transferring material.  If an operator has to carry a container of dry material and climb stairs, a Line Vac could be a much better alternative.

Heavy Duty Line Vac: Hardened Alloy Construction and High Performance

The Heavy Duty Line Vacs are made from a hardened alloy steel for abrasion resistance.  The generators inside these Line Vacs are more powerful than the standard models; so, that they can also convey heavier materials at higher conveyance rates.  They can reach rates as high as 40 lbs./min. (18.2Kg/min) of material.  With the hardened alloy construction, they are great for sand blasting applications, ceramic, glass and steel shot.  They are manufactured with inlet and outlet connections for ship-on hoses or threaded pipes.  EXAIR stocks the Heavy Duty Line Vacs in the range from ¾” (19mm) to 3” (76mm) for both hose and NPT connections.  These Line Vacs are our most powerful design with great wear resistance.

EXAIR’s Light Duty Line Vac

On the other end of the Line-Vac spectrum, EXAIR also manufactures the Light Duty Line Vac.   They use much less compressed air than the other Line Vacs which work great for moving lightweight materials over short distances.  They can also be used for removing smoke and fumes from a work area.  The Light Duty Line Vac ranges from ¾” (19mm) up to 6” (152mm) diameter for slip-on hose connections.  This two-piece design provides an effective way of moving material at a lower cost.  It can be used in applications like hopper loading, fiber tensioning, filling operations, and smoke removal.   For moving material within a short distance, the Light Duty Line Vac could be the proper product to use.

Model 161200-316 – 316 Stainless Steel Sanitary Flange Line Vac

Our latest engineering design within the Line Vac family is the Sanitary Flange Line Vacs.  They can fit within sanitary piping systems to convert pipes into a useful conveyor for bulk material and waste removal.  They use an ISO2852 flange for easy disassembly and cleaning to reduce bacterial entrapment.  They ae made from 316 stainless steel material for superior corrosion resistance.  They come in four different sizes to fit the sanitary flanges from 1-½” up to a 3” flange.  For sensitive applications where cleanliness is a major requirement, the Sanitary Flange Line Vac are manufactured for these conditions.

We are also able to make custom Line Vacs to mean any application, see an example of some unique to the application Line Vacs here, https://blog.exair.com/2020/07/01/custom-products-for-custom-applications/

With all of the EXAIR Line Vacs above, they can be sold as kits.  A kit will include a filter, regulator and a bracket.  (A bracket is not sold with the Light Duty Line Vac kits.)  The filter will help keep the Line Vac clean as well as the product that it is conveying.  The regulator is a great tool to vary the conveyance rates for better control.  The bracket helps to mount the Line Vac to a sturdy base for support.  A useful accessory to conveniently hide the compact Line Vac for ease of use and operation.

If you have any questions on how our Line Vacs can help save you money give us a call! One of our application engineers will be happy to assist!

Sanitary Flange Air Operated Conveyors – The EXAIR Line Vac

Published on by codybiehleLeave a comment

The ability to control the flow of materials has been a staple in human civilization since 4000 BCE. This includes the creation of pipes which have appeared as early as 2400 BCE from the Egyptians. These piping systems have since then been improved on to be made stronger, lighter, cheaper,  of various styles, and in a variety of materials. One of these styles is the sanitary flange pipe.

Sanitary flange pipe and fittings is one of the larger milestones in piping innovation. Sanitary flange pipes came about due the stringent cleanliness controls in certain industries such as food and pharmaceutical. Both of these use a highly corrosive and caustic soap to sanitize surfaces and, in most cases, entire rooms. Sanitary flange pipes allow for pipe systems to be taken apart easily so that components can be easily cleaned out on a regular sterilization process, and are generally made of 316 Stainless Steel to withstand the corrosive nature of the cleaning compound.

Type 316 Stainless Steel Line Vac

EXAIR Line Vac Air Operated Conveyors have always been well suited for these applications since the internal components are smooth and can be cleaned out easily and sanitized. They have also been made out of 316 Stainless Steel for years which provides superior corrosion resistance and can withstand most caustic cleaners and oxidants. Type-316 Stainless Steel is the preferred material for many food and pharmaceutical applications. Before EXAIR’s Sanitary Flange Line Vac, we noticed our customers would use the standard smooth Line Vac and weld a sanitary flange onto the ends, or installing adaptors on our Threaded Line Vac.

With that thought we decided to make things easier and developed the Sanitary Line Vac which follows the basic design of the Standard Line Vac and operates with the same performance characteristics. Sanitary Flange Line Vacs come in four sizes: 1-1/2”, 2”, 2-1/2”, and 3”. These sizes are the most common sizes for Line Vacs and covers the majority of application needs.

Sanitary Flange Line Vacs in increasing sizes: 1-1/2”, 2”, 2-1/2”, and 3”
