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.

Compressed Air Receiver Tanks On The “Demand” Side

Most any air compressor is going to have a receiver tank…from the “pancake” types that might hold a gallon or so, to the large, multi-tank arrangements that facilitate both cooling and drying of compressed air in major industrial installations.  The primary purpose of these receiver tanks is to maintain proper operation of the compressor itself…they store a pressurized volume of air so that the compressor doesn’t have to run all the time.  Receiver Tanks, however, can also be used to eliminate fluctuations at points of use, especially in facilities where there might be a lot of real estate between the compressor and the compressed air consuming products.

I recently had the pleasure of discussing an Line Vac Air Operated Conveyor application with a caller.  The need was to move wood chips, from inside to outside the plant, into trailers.  The facility has plenty of compressed air to operate the Line Vacs (the application calls for several) but because the point of operation is so far from the header, they’ll need a “stash” (the caller’s words…we call it “intermediate storage” but he’s not wrong) of compressed air to keep the Line Vacs supplied for operation without any dips in performance.

Enter the Model 9500-60 60 Gallon Receiver Tank.  When an application requires an intermittent demand for a high volume of compressed air, the Receiver Tank provides intermediate storage (or a “stash” – that word’s growing on me) to prevent pressure fluctuations and the associated dips in performance.

Model 9500-60 60 Gallon Receiver Tank

The Model 9500-60 has a small footprint for where floor space is at a premium, and meets ASME pressure vessel code specifications. It comes with a drain valve so you can discharge condensate and contaminants.  A check valve (not included) can be installed upstream to maintain the tank at max pressure so it doesn’t ‘back feed’ other upstream uses.

Use of intermediate storage near the point of use is one of our Six Steps To Optimizing Your Compressed Air System.  If you’d like to find out more about getting the most out of your compressed air, give me a call.

Sanitary Flange Line Vacs for Bulk Conveying

Piping systems have been a hallmark of human civilization for almost as long as people have been living in community with each other. Evidence of complex earthen pipe systems, with flanged fittings & asphalt sealants, date to 2700 BC. These were used for crop irrigation, potable water distribution, and wastewater removal in ancient civilizations from the Mediterranean to the Far East.

Over the centuries, new ways to use pipe led to new ways to make pipe.  Scientists and engineers figured out ways to make pipe stronger, lighter, cheaper, and in a variety of materials.  One of the more recent milestones is the development of sanitary piping and fittings.  The stringent cleanliness controls in certain industries (food and pharmaceutical, I’m looking at you) require highly corrosion resistant materials of construction.  The inside & outside surfaces of the pipe have to be finely finished so that they can be thoroughly and positively cleaned, with no crevices, “nooks & crannies,” etc., for material to gather or cling.  And since regular cleaning & sterilization is performed, the fittings must be able to be made & unmade in a manner that still provides for positive sealing when the system is restored to operation.

EXAIR Line Vac Air Operated Conveyors have always been well suited for applications like this.  With their open, unobstructed throats and smooth bores, they’re intuitively easy to clean, by design.  And we’ve made them, for years, in Type 316 Stainless Steel – the preferred material of construction for many food and pharmaceutical applications.  Many users in these industries were able to install them in sanitary piping systems by welding the flanges on our Stainless Steel Line Vacs, or by installing adapters on our Threaded Stainless Steel Line Vacs.

In the spring of 2017, EXAIR released the Sanitary Flange Line Vac with those same users in mind – eliminating the need to weld or thread flanges onto existing products.  They feature the same conveyance power as our Stainless Steel Line Vacs, and can even be modified to meet Heavy Duty Line Vac performance, if needed.  There are four sizes: 1-1/2″, 2″, 2-1/2″, and 3″…which covers the most popular size range of sanitary pipe systems.

While the sanitary piping systems are certainly most often found in those cleanliness-critical food & pharma type applications, other users incorporate them because of the smooth, continuous bore of the pipe and fittings, as opposed to a threaded pipe system, where the OD of the pipe threads into the ID of the fittings, causing a “step” in the throughput.  Because sanitary fittings mate via face-to-face flange seals, this eliminates that “step” which can make for a catch-point for certain items.  It’s for this very reason that a popular ammunition manufacturer uses sanitary pipe systems to convey shell casings…because they tumble with such turbulence in the air flow, they are especially prone to hanging up on any kind of catch-point.  So, they use sanitary piping & fittings, long radius elbows, and EXAIR Model 161150-316 1-1/2″ Sanitary Flange Line Vacs.

Air conveying of certain items, like these ammo shell casings, can be prone to clogging or jamming in systems where pipe, hose, and/or fittings are inserted into each other, creating catch-points.

EXAIR has a wide selection of engineered compressed air products that are “textbook” solutions for certain applications, but also make perfect sense for use in places you might not have thought of.  If you have a bulk material conveyance operation you’d like to discuss, give me a call.
