New Product: Ultra Duty Line Vacs™

To continue growth, EXAIR manufactures new products to either expand an existing line or to capture new markets. In this blog, I will cover the new Ultra Duty Line Vacs. When it comes to moving bulk materials with compressed air, EXAIR’s Heavy Duty Line Vac has long been the go-to choice for demanding applications. Its hardened alloy construction resists wear and delivers impressive conveying performance. But in some industries, the materials being moved are so abrasive that even the Heavy Duty version eventually shows signs of wear.

The Ultra Duty Line Vacs are designed to handle the conveyance of the most abrasive materials.  The bodies are made from the same material as our Heavy Duty Line Vacs, but we added a ceramic insert.  The ceramic material offers even more resistance to wear.  The overall length is a bit longer to accommodate this insert, but the flow rate, distance, and conveyance rates are the same. 

We currently offer them in 1 ¼”, 1 ½”, and 2” for hose connections individually or in kits.  We can offer the vacuum end with a threaded connection if required by adding the letter “E” as a suffix.  The kit versions will include a bracket for the Line Vac, a filter, a regulator, and a coupling kit for the filter and regulator. 

Here are the model numbers and versions that are currently in stock:

Air Operated Conveyors: Promotional gift!

If you’re performing any type of manual transfer of raw material in your processes, it might be time to take a closer look at EXAIR Air Operated Conveyors, or Line Vacs. The Line Vacs are designed as an ideal solution for the transfer of bulk materials from one point to another. They have no moving parts to wear, are very compact and easy to install, remove safety concerns, and do not require maintenance.  I will cover the many selections that EXAIR currently offers. 

Air Operated Conveyor

The Line Vac can move large volumes of material over long distances with just a small amount of compressed air. The compressed air is injected through directed holes that produce a vacuum on one end and high-volume output flows on the other. The Line Vacs are manufactured in several different materials and sizes, and with a few different options for connection style.  Adjusting the flow of material is extremely simple and can be controlled by regulating the air pressure upstream of the Line Vac.

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.

Standard Line Vacs are offered with a smooth inlet/outlet designed to be used with any smooth-bore conveyance hose. These Line Vacs are offered in aluminum sizes from 3/8” (10 mm) up to 5” (127 mm), and in 303 and 316 stainless steel from 3/8” (10 mm) up to 3” (76 mm).  Clear PVC conveyance hoses are available for 3/8” (10 mm) up to 3” (76 mm) I.D. from stock in 10’ (3 m) increments up to 50’ (15 m).

If you’d rather use rigid pipe, Threaded Line Vacs are also available directly from stock. With identical performance to the standard Line Vac, the Threaded Line Vacs are offered with NPT threads on both the inlet/outlet in sizes ranging from 3/8” NPT to 3” NPT in aluminum, 303, or 316 stainless steel.

For higher conveyance rates and abrasive materials, EXAIR offers Heavy Duty Line Vacs in the same manner as our standard or threaded units but are constructed from a hardened alloy steel. The Heavy Duty Line Vacs are offered with both smooth and threaded connection styles from ¾” (19 mm) up to 3” (76 mm).  The Heavy Duty Line Vacs are ideal for media that is abrasive in nature or for applications requiring higher conveyance rates over longer distances.

The Ultra Duty Line Vacs are designed to handle the conveyance of extremely abrasive materials.  The bodies are made from the same material as our Heavy Duty Line Vacs, but we added a ceramic insert.  The overall length is a bit longer to accommodate this insert, but the flow rate, distance, and conveyance rates are exactly the same.  This ceramic insert is placed where the conveying material hits the surface on the exhaust side, making it more durable and longer lasting.  We currently offer them in 1 ¼”, 1 ½”, and 2” for hose connections.

For applications where you only need to convey small volumes over short distances or particularly lightweight materials, our Light Duty Line Vacs would be an ideal solution. The Light Duty Line Vac is available in sizes ranging from ¾” (19 mm) to 6” (152mm) and consumes a bit less compressed air than the standard and heavy-duty versions. This style of Line Vac is only offered in aluminum construction and for use with smooth-bore hose.

Last, but certainly not least, is the Sanitary Flange Line Vac. The Sanitary Flange Line Vac is the best method for conveying materials in systems that require frequent or mandatory cleaning.  Utilizing ISO 2852-compatible clamp-style sanitary flanges, they can be easily removed from the system for periodic sanitization. These are offered in sizes ranging from 1-1/2”(38mm) up to 3” (76mm) in 316SS construction from stock.  They are ideal for applications in the food and pharmaceutical industries.

If none of these stock Line Vacs suit your process, we still have more options!! Custom units are available with varying styles of flange connections; Hybrid NPT threaded/smooth units can be done with stock components, we’ll even manufacture in special materials. At EXAIR, we take pride in offering custom solutions for customers that may require something just a little different from what is readily available on the shelf.

If there’s a process in your facility that could benefit from a product like the EXAIR Line Vac, act fast! Now through October 31st, you’ll receive a FREE 1122 2” Flat Super Air Nozzle as a promotion with the purchase of any EXAIR Line Vac with qualified orders.  If you need help with your application, EXAIR has Application Engineers to help you out.

NEW Product Spotlight: Ultra Duty Line Vac For Abrasive Conveying

When it comes to moving bulk materials with compressed air, EXAIR’s Heavy Duty Line Vac has long been the go-to choice for demanding applications. Its hardened alloy construction resists wear and delivers impressive conveying performance. But in some industries, the materials being moved are so abrasive that even the Heavy Duty version eventually shows signs of wear.

Enter EXAIR’s Ultra Duty Line Vac.

By incorporating a ceramic insert and a modified generator design, the Ultra Duty Line Vac dramatically extends service life when conveying extremely abrasive materials. The performance matches our Heavy Duty Line Vac, but its wear resistance is considerably greater. This makes it THE ideal solution for the toughest conveying challenges.

Why Ceramic?

Ceramic is known for its exceptional hardness and abrasion resistance, far greater than even hardened metals. By placing a ceramic insert at the critical wear points inside the Line Vac, we’ve created a conveying solution that can stand up to continuous service in applications that would rapidly erode other materials.

The Ultra Duty Line Vac shines in situations where the conveyed material is harsh on equipment. Examples include:

  • Mineral & mining products – Silica sand, alumina, crushed glass, garnet
  • Foundry & metalworking – Steel shot, grit blast media, cast iron chips
  • Ceramic & stone processing – Ceramic powders, crushed stone, tile dust
  • Recycling & waste processing – Shredded electronics, glass cullet, ground rubber with embedded fibers
  • Plastics manufacturing – Filled compounds containing glass fiber or mineral additives

In agriculture, conveying bulk solids can also mean dealing with abrasive materials. For example, certain soil samples, especially those with high quartz or sand content, can be unexpectedly harsh on equipment. The Ultra Duty Line Vac is an ideal solution for laboratories and field operations that need to move these samples quickly and reliably, without accelerated wear.

The Ultra Duty Line Vac is available in (3) sizes: Model 170125 (1-1/4”), Model 170150 (1-1/2”), and Model 170200 (2”). Each is also available in a kit configuration, which includes a mounting bracket, air filter, and pressure regulator for a complete, ready-to-install solution.

If you’re dealing with abrasive, difficult materials in your processes look no further than the EXAIR Ultra Duty Line Vac. They’re available to ship same-day from stock and backed by our unconditional 30-day guarantee.

Using EXAIR Products for “The Old One-Two Punch”

In boxing, there are five basic punches, and they’re commonly called out by numbers so that trainers can instruct boxers rapidly during the development of fundamentals. It’s also useful for them in real live bouts, where overly complicated plans can lead to defeat….former heavyweight champion Mike Tyson famously said, “everyone has a plan until they get punched in the mouth.” Those five basic punches are:

  • #1: The jab. Just like it sounds, this is a punch thrown directly forward with the lead hand. In many combinations, it’s the first punch thrown (that’s why it’s #1).
  • #2: The cross. This is a more powerful punch thrown with the back, or dominant, hand, and gets its power from the torque & rotation of the boxer’s body, when thrown correctly.
  • #3: The lead hook. This is an even more powerful punch than the cross. Its power comes not only from rotating the torso (like the cross) but also by pivoting on the lead foot to get the hip & shoulder involved. Because of the unbalanced and relatively unguarded position it leaves the boxer in, it’s riskier than a jab or cross, and oftentimes reserved for situations where the boxer sees an opportunity to score a knockout blow. If that plan doesn’t work, Mike Tyson’s famous quote above may very well come to fruition.
  • #4: The right uppercut. This is another devastating punch, thrown by the boxer’s dominant hand (assuming they’re right-handed) in an upward motion to contact the opponent’s head or body. If it connects to the chin or solar plexus, there’s a good chance the opponent will end up on the mat. It has to be thrown while the boxer is in close with the opponent, which gives the opponent the option to deal a devastating blow as well.
  • #5: The left uppercut. Same as above, but thrown with the boxer’s lead, or less dominant hand (again, assuming they’re right-handed.)

Because it generally leaves the boxer in a better defense position, the “one-two” combination is by far one of the most used moves in the ring. The term has even found its way into the popular vernacular, meaning two things that happen in rapid succession that lead to the desired outcome.

For the purposes of today’s blog (as the title suggests), I’m going to use it to describe an application where a customer uses two EXAIR products: a Model 1006SS Back Blow Air Nozzle, and a Model 6082 1″ Aluminum Line Vac in conjunction with each other.

This particular customer uses the Back Blow Air Nozzle to blow out the injector bore of an engine cylinder head assembly.

EXAIR manufactures three sizes of Back Blow Nozzles: our Model 1008SS Atto Back Blow Air Nozzle (left) is 0.2″ in diameter and can be used in 1/4″ to 1″ inside diameter holes, channels, etc. Model 11006SS 1/4 NPT Back Blow Air Nozzle (center) is good for 7/8″ to 4″ inside diameters, and Model 1008SS 1 NPT Back Blow Air Nozzle (right) is used for 2″ to 16″ inside diameters.

Thing is, they don’t want the debris flying all over the place. We considered a Chip Shield on the 1/4″ pipe extension that the Back Blow Air Nozzle was threaded onto, but since they insert it vertically from above, that could allow for debris to fall back down onto the assembly, and possibly right back into the injector bore, or one of the other openings on top. Instead, they opted for a Line Vac to vacuum the debris away as the Back Blow Air Nozzle blew it out of the hole.

While Line Vacs are primarily used to convey bulk material from one place to another (left), or to remove scrap trim (center), they’re also well suited for this application. Compressed air (1) enters the annular plenum (2) and is ejected at a high velocity through a ring of jets (3). This draws a vacuum on the inlet (4), creating a conveyance flow of air to carry whatever’s entrained in that flow through the outlet (5).

Engineered compressed air products have a multitude of advantages in applications like this. They’re durable & reliable. They have no moving parts to wear, or electrical components to burn out. They can operate continuously if needed, or they can be cycled on & off rapidly with no ill effects. If you’d like to find out how EXAIR Intelligent Compressed Air Products can help your operation, give me a call.
