Big Nozzle, Big Award…Again!

The year was 2016, and it was quite a time for sports fans:

  • Team USA dominated at the Summer Olympics in Rio de Janeiro. Swimmer Michael Phelps won five Gold Medals, and gymnast Simone Biles won a Gold Medal on her own, and another for the team event, contributing to the 46 total Gold Medals won by United States Olympians.
  • The Chicago Cubs and Cleveland Indians took the World Series to all seven games…and extra innings in Game Seven. That makes it hard to disparage either team, but the Cubs prevailed, winning the Fall Classic for the first time in 108 years.
  • World Series heartbreak notwithstanding, Cleveland sports fans were pretty happy a few months earlier when the Cavaliers cinched the NBA Championship in seven games, defeating the heavily favored Golden State Warriors…who beat the Cavs in both of their regular season games that year.

Another big winner (non-sports) that year was EXAIR Corporation’s Model EF5010SS External Mix Narrow Angle Flat Fan Pattern 1/2 NPT Atomizing Spray Nozzle…it won Plant Engineering’s Product of the Year Bronze Medal Award in the Fluid Handling category. Yes, there’s a Compressed Air category, and our products have won a TON of those too…as well as some other categories:

  • Material Handling (Line Vacs)
  • Maintenance Products (Super Air Nozzles)
  • Environmental Health (High Lift Reversible Drum Vac)
  • Automation & Controls (EFC Electronic Flow Control)
Just a few of our past Product of the Year award winners in categories other than “Compressed Air”.

Anyway, now it’s 2021, and the No-Drip version of that Atomizing Spray Nozzle – Model EF6010SS – has won Plant Engineering’s GOLD Medal Award in the Fluid Handling category. Model EF6010SS offers the same performance as the EF5010SS:

  • Liquid flow rates from 141 to 303 gallons per hour (tested with water)
  • Flat fan spray dimensions from 15″ wide (6″ from target) to 25″ wide (15″ from target)
  • Atomized spray at a distance of up to 35 feet away

And, of course, the No-Drip feature means you can instantly stop liquid flow by shutting off the compressed air supply, up to 180 cycles a minute, if needed. This is a great feature to have to cut down on the cost – and the MESS – associated with overspraying.

Our comprehensive line of Atomizing Spray Nozzles has options for most any liquid that can be sprayed, with a wide range of flow rates and pattern size/shapes. The 1/2 NPT External Mix Narrow Angle Flat Fan model is ideally suited for liquids with higher viscosities where a higher flow rate/thicker coating is needed, as opposed to a humidification or misting application, where a smaller Atomizing Spray Nozzle might be specified. Some current, successfully reported, applications include:

  • Snack food provider – applying flavoring to bulk snack materials.
  • Commercial bakery – spraying cooking oil onto pans used in a conveyor oven.
  • Sporting goods manufacturer – applying adhesive to the tops of skateboard decks to glue the grip tape on.

If you’d like to discuss a particular liquid spraying application, I’d love to help…give me a call.

Have A Blast (Of Cold Air) With EXAIR Vortex Tubes & Spot Cooling Products

The operation of a Vortex Tube is one of the more peculiar phenomena in fluidics, and a particularly unique method of producing cold air. Since they don’t perform “heat transfer” in the classical sense (see below), there’s no RATE of heat transfer…they’re generating cold air, at rated flow and temperature, instantly.

Compressed air enters the Vortex Tube (blue arrow) where the Generator imparts a spinning motion to the flow, which continues towards the “hot end” (red ribbon). The flow is forced to change directions and continue spinning, flowing in the opposite direction (blue ribbon). It’s at this point that the flow gives up energy in the form of heat, which is exhausted through the Hot Valve (red arrows) while the cold flow makes its way to the opposite end, where it exits at temperatures up to 129F colder than the compressed air supply.

EXAIR Corporation’s Vortex Tubes come in a range of sizes & cooling capacities, and are integrated into a number of Spot Cooling Products which add convenience and flexibility to their operation. Consider:

  • Vortex Tubes themselves are perfect for the most basic of installations. Small and Medium models weigh only a few ounces; you can thread them directly onto an existing 1/8 NPT (Small) or 1/4 NPT (Medium) fitting, if you have one (or can get one) adjacent to where you want to blow the cold air. Hot and Cold Mufflers can be added for sound attenuation, and the Cold Caps have 1/4 NPT (Small) or 3/8 NPT (Medium) female threads if you want to use a short pipe or hose to direct the cold flow.
  • Most spot cooling applications are best handled with the higher air flows and moderate temperature drops associated with a Vortex Tube product set to a high cold fraction. We have three distinct products that have a pre-set, non-adjustable cold fraction, aimed at these situations:
    • Mini Cooler Systems are quiet, compact, and ready to install in minutes via a Swivel Magnetic Base. They’re ideal for cooling small tools, needles in industrial sewing machines, saw blades, or lens grinders, just to name a few of the more popular applications. These come with built-in hot muffler, and are available with a Single or Dual Outlet Cold Air Hose Kit.
    • For applications that call for a higher cooling capacity, we offer the Cold Gun Aircoolant Systems. These have a bar magnet built in to the Cold Gun itself, integral Hot and Cold Mufflers, and, like the Mini Coolers, come with Single or Dual Outlet Cold Air Hose Kits. They’re most popularly specified to replace mist coolant in machine tools, but are also used on routers, grinders, drills, larger saws, and even some non-machining applications like chill rolls and setting hot melt adhesives.
    • For even higher cooling capacities than that, the High Power Cold Gun can be used. Size-wise, it’s identical to the Cold Gun, but it generates twice the Cold Gun’s flow of cold air.
Mini Cooler (left) and Cold Gun (right).

One of the main advantages of using these Vortex Tube products with the pre-set higher cold fractions is the prevention of freeze-up…while the cold air generated is usually just a little below 32F (0C), ambient conditions in the areas where they’re used typically add enough heat to prevent mass freezing of any moisture condensed in the cooling process. A number of applications, however, do indeed call for much colder air flow than this, and for those, we’ve got the Adjustable Spot Cooler:

EXAIR Adjustable Spot Coolers can generate temperatures as low as -30°F (-34°C) instantly, and on demand.

Their versatility makes them a great “utility player” – when very cold air (well below zero) is needed, the Temperature Control Knob is turned counterclockwise. If another application calls for higher flow (like the Mini Coolers or Cold Guns), it can be turned clockwise for instant adjustment of flow and temperature.

Adjustable Spot Cooler Systems are available with Single or Dual Point Cold Air Hose Kits, and come with three Generators: 15 SCFM (installed), 25 SCFM, and 30 SCFM, to select the compressed air consumption, and hence, the overall flow range.

If you’ve got a spot cooling application, EXAIR Corporation has a Vortex Tube solution for you. Give me a call; let’s talk cold air!.

EXAIR has a Line Vac for your Application!

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. 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.

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!
