What is a Super Air Amplifier

When I was working summers during school years I remember working in environments that were in unsatisfactory conditions. Since I was the the new kid and did not have seniority I had to take on the jobs that nobody wanted and therefore had the less than perfect working conditions. This company had a solvent welding process that at the time used Methyl Ethyl Ketone (MEK) as the bonding agent for ABS substrates. If only they knew about Air Amplifiers then! The solvent vapors on a hot humid Summer day would build up and I had to keep up with the quota while feeling a bit dizzy and disoriented! I couldn’t even run a fan as they were nervous blowing contaminants onto the substrates before going into the paint room. This is where a Super Air Amplifier could have helped.

Air Amplifiers are used for various reasons but in the story above could have been used for ventilation and keeping a safer work environment. Along with ventilating gasses/fumes these can be used for cooling hot parts, drying wet parts, cleaning machined parts, venting weld smoke, exhausting tank fumes, distributing heat within molds/ovens (circulation) and more! Super Air Amplifiers use the Coanda effect, a basic principle of fluidics, to create air motion. Using a small amount of compressed air as the source of power, the Super Air Amplifier then pulls in a large volume of surrounding air to produce high volume, high velocity outlet flows up to 25 times greater than the compressed air source.

Air Amplifiers use the Coanda Effect to generate high flow with low consumption.

Air Amplifiers have no moving parts making them virtually maintenance free to operate. No electricity is required. The flow, vacuum and velocity are easily controlled. Gross outlet flows can be adjusted by opening or closing the compressed air gap, which determines the amount of compressed air used. Supply air pressure can also be regulated to fine tune the outlet flow to meet application needs. Both vacuum and discharge ends of the air amplifier can be ducted, making them ideal for drawing fresh air from another location, or moving smoke and fumes away.

EXAIR carries a variety of sizes and styles and will even custom make Air Amplifiers for your every need. If you have questions about Air Amplifiers and want to talk to any of of many Application Engineers please contact us by calling 800.903.9247 or visit our website at www.EXAIR.com.

EXAIR’s New Catalog 33 with New Products and Added Information

EXAIR Corporation has been manufacturing intelligent compressed air® products since 1983.  If your company uses pneumatic systems, EXAIR has solutions to save you money in compressed air usage, improve your safety environment, and increase productivity.  You can review these products and our new products in Catalog33, or you can speak with an Application Engineer.  We are looking forward to working with you. 

For those of you that have been patiently waiting for the new catalog, we have great news! Catalog 33 is now in house. You can find it in our website as pdf files at this link, Catalog33.   We also have hard copies that are now available.   If you are like me and enjoy something to hold and read, you can fill out this form, Catalog Request.  Since Catalog32, we have released quite a few new products that are now included in Catalog33.  Here they are:

The EasySwitch® Wet/Dry Vacuum (page 167 – 168 in catalog) – In our Industrial Housekeeping Products, we made an industrial vacuum to pick up both liquid and solid materials.  The patent-pending EasySwitch vacuum simplifies the filter change process when switching from a dry material application to liquid, and vice versa.  Designed to handle the toughest of industrial cleanup jobs, the EasySwitch is available with either a standard or HEPA certified filter. It easily converts from liquid/dry mode by releasing the single latch and removing the filter element. For applications where dedicated wet and dry vacuum are needed, the EasySwitch is the ideal solution; one vacuum for wet, dry, light, and heavy applications.

Liquid Atomizing Spray Nozzles (FullStream/HollowStream) (page 98 – 102 in catalog) – EXAIR’s FullStream & HollowStream Spray Nozzles require no compressed air to operate. They produce droplets by spinning the liquid and breaking its surface tension through a precision orifice or by impacting the liquid onto a surface of the nozzle. These nozzles generate higher liquid flowrates and produce a coarser pattern than the Air Atomizing Spray Nozzles.  With the higher liquid flowrates, they are ideal for quenching, cooling, washing, rinsing, sanitizing, and many other applications. 

Intellistat® Ion Air Gun™ (page 138 – 139 in catalog) – The Intellistat Ion Air Gun is a lightweight solution for static elimination operations. This intelligent product utilizes balanced ionized compressed air to neutralize static and remove particulates during clean processes, test procedures, and sensitive assembly work.  The Intelistat Ion Air Gun comes equipped with a short-throw effortless trigger and the lightweight and ergonomic frame allows extended periods of use without experiencing operator fatigue.  The ionizing gun comes complete with a 6mm air connection and tubing, red and green LED lights for feedback, a removable hook for easy storage, and a low-voltage 24 VDC power supply.  The Gen4 Static Eliminators are great tools for industrial applications, and the Intellistat Ion Air Gun is ideal for laboratories, electronics, lenses, medical, pharmaceutical, etc. type of areas. 

VariBlast® Precision Safety Air Gun (page 105 in catalog) – The VariBlast Precision Safety Air Guns are very lightweight and deliver a focused blast of air.  This product line completes our Safety Air Guns from precision small blowing to the Super Blast.  Designed with the same style of variable force trigger as the VariBlast Compact Safety Air Guns, it’s easy to adjust the flow/force from the gun simply through the trigger.  New to this style of gun is the ability to install different length extensions, chip shields, and small Safety Air Nozzles. 

Catalog 33 also added additional pages containing best practices for using compressed air products.

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.
