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.

Super Air Amplifiers: Evacuation of Smoke or Fumes

Air Amplifiers Are Great For many things!

In the pneumatic industry, there are two types of Air Amplifiers.  One type will amplify the inlet air pressure to a higher pressure.  The other type uses the inlet air pressure to amplify the air volume.  EXAIR manufactures the volume type called the Super Air Amplifiers™. 

This change in air volume is called the amplification ratio.  So, what does this mean?  The definition of ratio is the relation between two amounts showing the number of times one value is contained within the other.  For the EXAIR Super Air Amplifiers, the ratio is the value that shows the amount of ambient air that is drawn within the compressed air.  The higher the ratio, the more efficient the blowing device is.  The EXAIR Super Air Amplifiers can reach amplification ratios up to 25 to 1.  This means that 25 parts of ambient “free” air is introduced for every 1 part of compressed air. 

Why an EXAIR Super Air Amplifier?  Like a fan, they are designed to move air.  But fans use motors and blades to push the air toward the target.  The fan blades “slap” the air which creates turbulent air flows and loud noises. The Super Air Amplifiers do not use any blades or motors to move the air.  They just use a Coanda profile and a patented shim to create a low pressure to draw in the ambient air.  In physics, it is much easier to pull than it is to push.  The process of pulling air through the Super Air Amplifiers make them a more efficient, uniform, and quiet way to blow air.    

Super Air Amplifier – flow region

To show the power of the Super Air Amplifier, we have a video of a model 120022.  In the video, oil is being heated to generate smoke, and the Super Air Amplifier is placed in the center of an exhaust pipe.  This demonstration was for a customer that was looking to evacuate vapors from an enclosed area.  Other applications would include welding smoke, ventilation, exhaust tank fumes, and dust collection.  You can see when the Super Air Amplifier is turned on and in operation in the video below. 

EXAIR manufactures and stocks five different sizes ranging from ¾” (19mm) up to 8” (203mm) in diameter.  Some of the benefits that the Super Air Amplifiers have is the inlet and outlet can be ducted for remote positioning.  They are very compact and can fit into tight places like the exhaust pipe above.  They do not have any moving parts to wear or need electricity to run.  They only need clean compressed air to operate; so, they are maintenance-free.  Another unique feature of the EXAIR Super Air Amplifier is the patented shim which optimizes the low-pressure to draw in more ambient air.   As an added bonus, they are OSHA safe and meet the standards for noise level and dead-end pressure. 

With the today’s cost to make compressed air, it is important to use it as efficiently as possible.  The EXAIR Super Air Amplifiers have the ability to give effective blowing to remove debris, dry parts, transport material, cool objects, and clear smoke without using a large amount of compressed air.  EXAIR has the Super Air Amplifiers in stock and as always, EXAIR offers a 30-day unconditional guarantee for our customers in the U.S. and Canada to try them out.  If you have any questions about the Super Air Amplifiers or if you would like to discuss your application, an Application Engineer at EXAIR will be happy to help you.

The EasySwitch™ Wet-Dry Vac won the Silver Award!

EXAIR has been manufacturing Intelligent Compressed Air Products since 1983.  In that time, we have engineered many new products for new and existing markets with better efficiency, versatility, and effectiveness.  To gauge how a new product is received by your peers, we like to send them to different committees for evaluations.  Last year, we sent our EasySwitch Wet-Dry Vac to Plant Engineering to compete against other new products in the manufacturing and non-manufacturing industries.  In the Maintenance Tools and Equipment category, the EXAIR EasySwitch Wet-Dry Vac won the Silver Award. 

How was EXAIR able to achieve such a prestigious award?  Well, let me tell you how our newest Industrial Housekeeping Product was able to receive this award.  I will discuss the features and benefits, so you can decide for yourself.

We have joined our wet vacuum with our dry vacuum to make the EasySwitch Wet-Dry Vac System.  This new addition to our Industrial Housekeeping Products allows your customers to replace their electric wet-dry vacuums that fail prematurely, have potential safety issues, and are very loud.  You can watch a video of the operation HERE.

A wet-dry vacuum is a contained system that can vacuum up liquid or dirt.  The specific design that separates the liquid application from the dry application is a filter element.  The filter will stop the dirt and debris from re-entering the surrounding air during vacuuming.  The EXAIR EasySwitch Wet-Dry Vac uses this same function; but we offer two different types of filters; a standard filter and a HEPA filter.  The standard filter is a 3-micron pleated element with a large surface area for long life.  The HEPA filter is a 0.3-micron pleated element for finer filtration.  But what is unique about our design is the patent-pending lid to easily remove or replace the filter elements.  Unlike our competitors, you will have to remove the lid and use a tool to either remove or install the filter.  This is time consuming and a headache.  Our lid design makes an easy transition to go from liquid to dry materials and vice versa.   The EasySwitch Wet-Dry Vac is designed to fit on a common 55 gallon open-top drum.  They are ideal for any applications that is wet, dry, light or heavy. 

Like with our other Industrial Housekeeping Products, the EasySwitch does not have any motors to wear or electricity to run which makes it safe for liquid applications.  It only needs filtered compressed air.  They are maintenance free, and the sound level is quiet, only 79 dBA.  The applications include coolant, chips, floor cleanup, drains, shavings, sawdust, absorbents, and mold/allergen removal.  For liquid applications, it has a spill free – auto safety shutoff.  This industrial all-purpose pneumatic vacuum can move 36 GPM (136 LPM) of water, 68 Lbs./min (31 Kg/min) of plastic media, and 54 lbs./min (24 Kg/min) of steel shot at 80 PSIG (5.5 bar).  The specifications at 80 PSIG (5.5 bar) for the EasySwitch is that it will only use 53 SCFM (1,500 SLPM) of compressed air to generate -168” H2O (-314 mmHg) of vacuum and 90 CFM (2,548 LPM) of vacuum flow. 

EXAIR offers three types of systems with the standard filter or the HEPA filter.  We have the basic system, the Deluxe system, and the Premium system.  The basic system will come with the selected filter with a prefilter, 10-foot (3m) vacuum hose, 20-foot (6.1m) compressed air hose, plastic tools, shutoff valve and gauge.  The Deluxe system will include the items in the basic system with an upgraded antistatic vacuum hose, heavy-duty tools, a spill recovery kit, a tool holder, and a drum dolly.  The Premium system will include the items in the Deluxe system plus a 55 Gallon drum.  A quick guide is below. 

Model number selection guide

Not all industrial vacuums are the same.  Electric wet/dry vacuums fail prematurely, generate loud noises, and are cumbersome for filter change-outs.  This is why the EXAIR EasySwitch Wet-Dry Vac was awarded the Silver Award by Plant Engineering; longevity, quietness, and ease-of use.  If you are within the U.S. or Canada, we do offer a 30-day unconditional guarantee to try them out.   You will not be disappointed.  If you would like to discuss in more detail, an Application Engineer at EXAIR is here help.
