A Line Vac Air Operated Conveyor System Really IS Just That Simple. Seriously.

I’m a skeptic by nature. “If it sounds too good to be true, it probably is”, is engrained in my cerebral cortex as firmly as anything else. And I know I’m not the only one, if only because of the conversations I have with callers about our Line Vacs. Here are some of the questions we’ll get:

“What all do I need?” Here’s a basic system:

A Line Vac.
A length of hose to get from Point A to Point B.
A supply of compressed air.
Something to convey.

That’s it.  You might need something to hold the hose in place.  Or maybe a Mounting Bracket for the Line Vac to hold IT in place…if so, one comes in the Kit.  Which brings me to the next question…

“What ELSE do I need?”

This depends on what you’re conveying.  Anything in your compressed air supply to the Line Vac can get on (or in) the product passing through.  Our Kits include an Automatic Drain Filter Separator, which keeps the air clean & dry.  If you need to keep any trace of oil from your product, we’ve got Oil Removal Filters, which can couple right to the Kit’s Filter Separator.  Not only do they use a coalescing action to remove any trace of oil, they provide additional particulate filtration down to 0.03 microns.  THAT’S some clean, dry air right there.

“What’s the catch?”

By and large, the mission of the Application Engineering staff at EXAIR is to eliminate any “catches.”  We’ll discuss your application with you and make just as solid of a recommendation as we can with the data provided.  We’ll talk about:

The physical nature of your product.  If it can make a combustible mixture with air, we won’t specify a Line Vac.  If it’s particularly low density, we’ll discuss the Light Duty models.  If it’s abrasive or particularly high density, we’ll go to the Heavy Duty models.  If it’s corrosive, we’ve got Stainless Steel.

The environment it’ll be used in.  If it’s hot (or corrosive, like the product,) we’ve got Stainless Steel.  If it’s REALLY hot – up to 900F (482C) – we’ve got High Temperature units.

How you want to hook it up.  We’ve got Conveyance Hose for our standard Line Vacs…it’s reinforced PVC and is awesome for typical industrial/commercial uses.  If you want to use hose with specific properties (food grade, static resistant, high temperature, etc.,) these are all readily commercially available, and are quite commonly seen in successful Line Vac installations.  Our Threaded Line Vacs can be used with NPT pipe fittings & connections for more permanent setups.

Lastly, the “catch” is ours…not yours.  If, after a thorough discussion (mind you, I can talk about Line Vacs all day long…and sometimes I do,) there are still some variables or unanswered questions, we offer all catalog products with a 30 Day Unconditional Guarantee.  Try it out – if it doesn’t do what you want, we’ll arrange return for full credit; easy as that.  It’s the complete absence of “catch.”  Oh, and if you buy a Line Vac before October 31, 2016, you’ll get a free 2″ Flat Super Air Nozzle.

If you’ve got a Line Vac – or any Engineered Compressed Air Product – application you’d like to discuss,  give me a call.

EXAIR Air Nozzle Provides Non-Marring Solution For Rotary Die Cutting

Die Cutting is a highly efficient means to produce large volumes of uniquely shaped parts while creating a low volume of wasted materials. There are several different ways to produce die cut parts with one of the more common being Rotary Die Cutting. A Rotary Die Cutter typically incorporates the material passing between a roller die cutter and a heavy roller anvil to cut the specific shape  then passes the material down a conveyor or feed line while retrieving the waste material in another collection device.

I recently worked with a customer who was starting to see a large volume of scrap in their vinyl and rubber parts die cutting process as the die cut parts themselves were getting stuck onto the rolling die cutter and weren’t getting grabbed by the conveyor rollers. To try and get the parts to eject from the cutter they installed a few 1/4″ open copper tube air lines running across the roller but were concerned with amount of air they were wasting and the high pitch noise levels of close to 100 dBA. They were also seeing some damage to the parts they were able to get loosened from the die as some of the parts would make contact with the pipe, causing a “blemish” on the part, ultimately failing inspection.

I recommend the customer use our Model # 1100-PEEK Super Air Nozzle. The Model # 1100 consumes only 14 SCFM of compressed air (at 80 PSIG), much less than a 1/4″ open pipe, tested at close to 140 SCFM @ 80 PSIG. This nozzle produces a low sound level of only 74 dBA falling well within the allowable noise exposure levels set forth by OSHA. In addition, the PEEK plastic construction provides a non-marring solution in the event one of the parts did make contact with the nozzle.

Flexible Stay Set Hoses

Adjustability and flexibility have been common themes for some of my recent blog posts. The EXAIR Flexible Stay Set Hoses certainly exhibit those same characteristics and more. For applications where frequent re-positioning of the air product, whether it be a Super Air Nozzle or Jet, or small Super Air Knife, the Flexible Stay Set Hoses are ideal.  Simply mount the hose near the area of application, and bend and shape it to deliver the air flow precisely as needed.

stay-set-hoses

Flexible Stay Set Hoses

The hose was designed and manufactured to have “memory”, and it will not creep or bend. It will maintain the positioning and directional aim of the air flow until it is reshaped to a new position.  The materials of construction allow it to withstand temperatures up to 158°F (70°F.)

The Flexible Stay Set Hoses are offered in 5 different lengths – 6″, 12″, 18″, 24″, 30″, and 36″ and with 2 different end configurations – 1/4 male NPT x 1/8 female NPT and 1/4 male NPT on both ends, providing many options to match the needs of the application.

The Magnetic Base works in conjunction with the Stay Set Hoses, as they also allow a flexible location for positioning the hose.

EXAIR Chip Vac Removes Swarf and Keeps the Machining Center Running

The word of the day is “swarf”. Swarf is fine chips or filings of stone, metal or other material produced by a machining operation.

A company had four automatic profile cutting machines to cut aluminum stock.  They contacted me for help to improve their operation.  Each machine had a cleated belt conveyor to remove the swarf (or chips) from the cutting process.  Because the swarf was small in size, the chips could get around the edge of the belt and affect the conveying system.  Two of the four conveyors failed, and they wanted to find a better option to remove the swarf and keep the machines running.  They sent me a photo of the type and size of the swarf that was thwarting their conveying system.

EXAIR receives many calls about applications similar to this. I suggested the model 6193 Chip Vac System.  This assembly will fit onto a standard open-top 55 gallon drum which has a much smaller footprint than the conveying system.  The 0.1 micron filter allows for the air to escape and keep the fine particles inside the drum.  For this customer, once the drum was filled with aluminum chips, it was easy to rotate in an empty drum, sending the full drum of material to recycling.  The vacuum generator has no moving parts which makes it quiet, maintenance free, and long lasting.  It also creates a high vacuum level which was very useful when they attached it near the chip collection area.  The Chip Vac System was easy to install and it was very beneficial in keeping the machining area clean and running.

Let Us Help You Cool Your Electrical Control Panels

The warmer temperatures of summer are dragging on a bit late this year in Ohio, which can be great for weekend activities, but forces us to wait just a little longer before the weather officially “breaks”.  And, while the bringing of a new season may be a welcome change for many, the outside temperatures remaining high can mean an increased risk of overheating electrical panels.  Case in point, the images below show an electrical control panel with internal temperatures as high as 65.3°C with ambient temperatures around 35°C.

This thermal image shows the view of an electrical control panel from the outside

At their maximum, components inside this enclosure reached as high as 65.3 degrees C

This type of scenario is common not only during the summer, but also of industrial manufacturing areas with heat producing equipment such as CNC machines, lathes, centrifuges, screw machines, molding machines, etc.

Thankfully, the solution for these applications is the same.  Using only compressed air, our Cabinet Coolers alleviate overheating conditions in control panels, regulating both temperature and humidity (relative humidity is regulated to 45% with the use of an EXAIR Cabinet Cooler).  By completing our Cabinet Cooler Sizing Guide, anyone can gain access to our Application Engineering staff and have the heat load of their application calculated by a trained engineer.  We can then make a recommendation as to the exact system needed for your application.

If you’re experiencing problems with overheating electrical control panels, contact an EXAIR Application Engineer.  We’ll be happy to help.

Quick, Cool, and Quiet – The EXAIR Adjustable Spot Cooler

I recently had the pleasure of assisting a caller with a cooling application. We’ve written before (more than once) about cooling applications & product selection, and I had a very similar conversation with this caller. Since the need was for cooling as quickly as possible to ambient temperature, the caller was keen on talking about Vortex Tubes.

This application entails operators placing small products, by hand, under the cold air flow for rapid cooling.  Now, a Vortex Tube can produce VERY low temperatures…down to -40F…so operator safety had to be addressed.  By keeping the Cold Fraction (the percentage of supply air flow which is directed to the cold end) high, we can also keep the temperature high enough to not present a hazard (i.e., frostbite) but still plenty low enough for effective cooling.

Since sound level was also a concern, we discussed mufflers…with Hot and Cold Mufflers installed on a Medium Vortex Tube (models 3215, 3225, or 3230, which were what we narrowed our discussion to,) a sound level of 81-84 dBA will be produced.  That’s within OSHA’s limits for 8-hour exposure, but isn’t exactly “communication-friendly” for operators that need to talk to each other on a regular basis.

The Model 3825 Adjustable Spot Cooler System incorporates the performance of the three Vortex Tube models that we were talking about into a convenient mag base mounted assembly, fitted with a cold muffler, flexible cold air hose, and additional sound level suppression to 72-74 dBA…which makes a significant difference in areas where operator conversation is critical.

EXAIR's Adjustable Spot Cooler provides cold air, on demand - quiet and easy!

The temperature control knob allowed them to dial in the optimal cold air flow, keeping the temperature low enough, and flow high enough, for rapid cooling of the parts.

If you’d like to find out just how cool an EXAIR Vortex Tube/Spot Cooling Product can make your application, give me a call.

A Good Example of Dedication and Commitment from the First Grade

This year, my oldest daughter started First Grade.  My second daughter will be starting preschool two days a week, and the youngest, well she just has no fear and doesn’t see the consequences of her actions at this point in life.   To say the least, the past few weeks have been extremely busy, as I am sure it has been for most of us.

A Great Message For School. (Not On Our Schools)

A Great Message For School.

I went to the parent – teacher introduction night with my beautiful wife and we got to meet the first grade teacher who definitely has her work cut out for her.   The amount of effort and care this teacher has poured into this class is already apparent in the first week of school.   She sent us all her personal cell phone number, sends out updates through a smartphone app, and has even told all parents that if a child in her classroom is involved in an activity outside of school that she will attend one of these events because she wants to see the children in their element and see what makes them happy.  All of these “extra” things the teacher does, she doesn’t get paid for, and is strictly doing out of her love for teaching and the children she teaches.  She legitimately loves her job and wants to see each of these students succeed in life.

There are people who teach that go to their job and give the bare minimum to not get let go and to merely collect a paycheck.   There are also a great number of educators that go above and beyond every day of the school year.  When it comes to teachers, so far my oldest daughter has been extremely blessed.  She had an amazing teacher for both Preschool, Kindergarten, and now even First Grade.   Each of these has also been at 3 different schools where she has thrived and I could not be happier with our school district.  I even mentioned to my wife, who is a former primary teacher, that I do not look forward to the year that one of our three daughters has a teacher that she does not agree with.  (That is going to be an extremely long year.)

Just as I noticed the level of dedication from the teachers I have had the joy of meeting, I have also realized that in order to succeed and thrive, there has to be dedication and going beyond the minimum.  This is what I see everyday when I walk through the doors here at EXAIR.  Whether I am walking through the front offices or the production areas, we by no means have a single team member that gives the minimum.  Every person here cares about whether or not the other succeeds, and we all work together with the same goal, blow our customer’s expectations out of the water.  This is just one reason we continue to release new products, offer the best means to contact us, as well as ship stock products same day, and provide order confirmations and install support for every single order.
