316SS Sanitary Flange Air Operated Conveyors Pull Corn Meal Quality Samples

Agriculture, it’s a word that invokes a lot of imagery. From the vast rolling fields, to animals roaming, to a simple life of tending to the land. For some it is the perfect life of hard work and simple living. Agriculture can make one think of tractors, heavy equipment, silos, fencing, and much more. But there is one thing that does not typically come to mind, and that is compressed air. Even though compressed air is not commonly thought of being used in agriculture does not mean that it cannot be used. In fact, it can be very useful.

In one application a manufacturer of corn meal needed to take a sample of the product to test the moisture content and quality before it was loaded into a rail car. The lab tech use to have to go out to the silo to scoop up about a pint and transport it back to the lab to be tested. To eliminate the manual retrieval and delivery of the corn meal EXAIR recommended a model #163300-316 3″ St. St. Sanitary Flange Line Vac Kit and was sold to the customer. A system of 100ft of pipe was installed from the silo to the lab so that the test sample could be conveyed by the Line Vac directly to the lab to be tested. This simple fix improved the reliability of the sample and decreased the time it takes to grab a sample. Along with the added benefit that now the lab tech does not need to walk over and scoop the sample out of the container or off the ground.

EXAIR’s Family of Sanitary Flange Line Vacs

Line Vacs are a great product for conveying bulk material from point A to point B and excel with “bucket and ladder” type scenarios where personnel is manually loading or unloading batches of material or scrap. EXAIR’s Air Operated Conveyors have always been well suited for applications involving food as the internal components are smooth and can be cleaned out easily and sanitized. With a 316 Stainless Steel body the unit provides superior corrosion resistance and can withstand most caustic cleaners and oxidants. The flange style connection also makes it easy to hook up and remove for cleaning purposes.

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

Sanitary Flange Line Vacs are all made from 316 Stainless Steel and come in four sizes: 1-1/2”, 2”, 2-1/2”, and 3”.

EXAIR Cold Gun, Different Application, Problem Solved!

Recently I was working with a customer on sizing a EXAIR Cabinet Cooler when I found out they would be best suited by another EXAIR product! They wanted to cool some analyzer panel fins (heat sinks) while keeping dust off of them. This application said Cold Gun all the way!

I recommended our Model # 5315 Cold Gun Aircoolant System with two cold outlets. The Cold Gun produces a 50°F temperature drop from compressed air supply temperature and provides 1,000 Btu/hr. of cooling capacity. For example, if your compressed air supply temperature is 70°F you would effectively see 20°F air being discharged from the cold exhaust. The Dual Point Hose Kit splits the cold airflow into 2 separate streams, providing for a wider coverage area.

The customer decided to order a single unit and after a week of testing replied back…

“We tried one a week ago with excellent results! We are installing three more today. 

Thank you so much for your help! Our analyzer is running 31°F cooler than it had been with no more overtemp failures!”

It goes without mentioning, but this is the type of positive feedback we are thrilled to hear! It feels incredible when a customer takes time out of their busy schedule to acknowledge how EXAIR products provided the perfect solution for their needs!

BUT the story doesn’t end there… just last week, over 2 months since our last correspondence, the customer sent me another email that read…

“Just a follow up on the effectiveness of the cold air guns. We have not experienced a single failure of our TOC analyzers since the guns were installed two months ago.

The cold air solved the problem of our analyzer overheating — even during the hottest part of the summer.

Thank you for your excellent recommendation!”

I let the customer know how much we appreciated the awesome news and how happy we were to be able to solve their problem. At the end of the day, that’s what we strive for, to provide the best and largest selection of Intelligent Compressed Air Products on the market today.

EXAIR Siphon Fed Air Atomizing Liquid Spray Nozzles

Amongst EXAIR’s continuously growing product offering, some of the newest are a family of Air Atomizing Liquid Spray Nozzles that does not require a pressurized liquid source. These are known as the Siphon Fed Air Atomizing Nozzles. These nozzles can be easily implemented where a tank can be installed and lower the cost of the installation by not requiring a liquid pump, just point of use compressed air.

Siphon Fed model

This action is done by the unique design of the air cap.  As the velocity of the air passes through the air cap, low pressure is created by a venturi.  The Siphon Fed Atomizing Nozzles can draw liquid from a suction height of 36” (91 cm), or gravity fed. They are manufactured from 303 stainless steel for durability and corrosion resistance. The Siphon Fed models can spray viscous fluids up to 200 centipoises and are used in many applications like rinsing, coating, cooling, quenching, humidification, or dust control. The images below showcases how simple the setup can be for the siphon and gravity fed installations.

EXAIR Siphon Fed Nozzles work with non-pressurized liquids, either siphoned (left) or gravity fed (right.)

EXAIR carries three different body sizes, 1/8” NPT, ¼” NPT, and ½” NPT ports; so, you can create a light mist or a heavy spray of liquid.  The maximum liquid flow rate is controlled by the air cap and liquid cap combination.  A unique feature of the EXAIR Atomizing Nozzle is that the caps are easily interchangeable for each body size to modify the spray patterns, control the amount of fluid, and reduce any downtime if cleaning is required.  The video below shows just how easily the changeover is done.

In addition to the three different inlet/body sizes, we also offer the Siphon Fed in both a round spray pattern or a flat fan spray pattern. These are also controlled by the air and liquid cap combination. This means it is easy to convert a round pattern that may be needed for a job, over to a flat fan pattern for the next setup. Each pattern is also available in several flow rates of liquid and air to dial in the performance required by the application.

Siphon Fed Air Atomizing Spray Nozzles

Additionally, if you would like to positively shut the liquid flow off from the nozzle in order to prevent drips, over use of liquid, or to shut off the gravity fed liquid when not needed, the No-Drip versions of these nozzles is also available. This is easily controlled by simply reducing the compressed air operating pressure to below the designated cracking pressure of the patented No-Drip valve.

Utilizing CAD Files

When I was in 6th grade, our art teacher, Mrs. C, taught us to draw fruit one day. I was academically gifted (I’d had straight A’s since 1st grade) but I was AWFUL at drawing. I was doing OK with my orange, apple, and even my banana. When it came time to draw a pear, I realized I had 35 cents in my pocket (that’s what milk for snack time cost) so I pulled out that quarter & dime, used them to trace a quarter-sized circle with a dime-size circle slightly intersecting it, erased the middle parts, and “free-handed” little arcs to complete the pear shape. Mrs. C told me I wasn’t allowed to do that and gave me my first bad grade – ever. Now, I LOVE going to art museums and taking in the wonders of those who are far more skilled than I with pen and brush, but I STILL have no aptitude or desire for drawing anything myself….with a pen or brush, that is.

My first job out of the Navy involved some very basic CAD use…mainly making simple changes or additions (and usually just title block text) of existing drawings. As I more familiar with CAD, I realized the method for drawing a pear shape in CAD was, in fact, my own personal grade school method: intersect two circles, trim, and fillet. So there, Mrs. C!

My next job took my CAD utilization a bit further…making assembly drawings of systems, using existing CAD files for the individual components that made up the system. The key word there was “existing” – the First Law of CAD is, “Don’t ever draw anything twice.” So, I’d get CAD files from the manufacturers, insert them into my template, put them where I wanted them to be in relation to the other pieces of my little puzzle, send the drawing(s) to the end user for piping and foundation prep, and as long as the folks in the shop followed my drawings (which is was hard not to), everything worked out great.

Now, this was way back in the 1990’s, so I got most of my CAD files via email, and, occasionally, on 3.5″ floppy disks or CD’s. EXAIR Corporation has offered drawing files for our products in our CAD Library for many years now. You can always find four fundamental file extensions:

  • PDF – these can be opened with Adobe Acrobat…they’re “just for looking at”. They don’t denote any particular scale, and won’t directly import to a CAD file. They’re useful for quick & easy answers about overall dimensions, bolt hole sizes, thread pitches, etc.
  • DWG – this is AutoCAD’s “native language.” These files will open seamlessly in AutoCAD, if that’s what you’re using, along with many other programs. But, if it doesn’t.
  • STP – we’re well in to the 21st Century, and many designers have moved on from the above mentioned 2D files to solid models. Most solid modeling programs are compatible with these files.
  • SAT – these are, to STP, what DXF is to DWG…a “more friendly” file for certain solid model programs.

With the launch of our new website, we now offer 64 native extensions so you (hopefully) do not have to modify, import, or convert any drawing that would take additional modification – just download the file you need right from our Resources, 3D Models and CAD drawings link. And dare I say, if you can’t find the extension you need, you are using some fairly obscure software – perhaps an SAT or STP file will suit you.

If you’re designing a system or making an assembly drawing incorporating EXAIR catalog products, we have all of these in the CAD Library. If you need one for something that’s not in the catalog – a Super Air Knife less than 60″ long with a Plumbing Kit installed, for example – we can provide that as well...just contact an Application Engineer.
