Air Amplifiers to Increase Volume of Airflow Aid in Cooling, Cleaning, Circulation, Venting

Air Amplifiers are a perfect solutions for utilizing air for Venting, Exhausting, Cooling, Drying, or Cleaning with no moving parts. As the name implies, these tools produce a high volume and a high velocity of outlet flow. These are very quiet, efficient and can amplify your air consumption up to 25 times… Here is a great diagram and description of exactly how these work:

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

As you can see, these fine pieces of engineering genius have no moving parts, and require no electricity. You can easily control the flow, force and velocity by opening or closing the air gap (fixed with a shim) and regulating the the supply air. These can also be ducted on each end to either pull in or remove air or fumes from one room or area to another.

SUPER?? What makes our Super Air Amplifier super? I’m glad you asked. The Super Air Amplifier has a patented design that uses a special shim to maintain critical position of the component parts. This results in a precise amount of compressed air to be released at exact intervals towards the center of the Super Air Amplifier. These jets of air create a constant, high velocity outlet flow across the entire cross-sectional area. This balances out the airflow to maximum performance, this simultaneously minimizes wind shear, causing sound levels up to 3 x’s quieter than other comparable air movers. To completely understand how much air this Super Air Amplifier amplifies (try saying that fast 5 times), please see the below chart.

As you can see, the amplification ratio is between 12 and 25 x the amount of air consumed. For the right applications, these are game changers… Pro tip – notice that even the highest level still falls under OSHA guidelines for noise!!

If you have any questions, or would like to discuss your application directly, please reach out today. We would love to speak with you, and help wherever we can.

“Free” Ambient Air Entrainment w/ EXAIR’s Super Air Amplifiers

When working with a cooling application, many customers will immediately look to the Vortex Tube and Spot Cooling product lines. While this may be the best solution for some applications, cold air is not always the best method that we have available for cooling. EXAIR’s Super Air Amplifiers are very effective at reducing the temperature of a part without requiring cold air. The Super Air Amplifiers get their name due to their ability to entrain ambient air and “amplify” the supplied compressed air. You’ll often see us referring to the air amplification ratios achieved with our products. This is a ratio of the supplied compressed air relative to the entrained “free” air that comes from the ambient environment.

Due to their ability to entrain large amounts of ambient air, we can move a high volume of air across the surface of the part and quickly lower the temperature. I like to compare this to blowing on a hot cup of coffee just as it’s been brewed. The temperature of the air coming from your mouth is around 98.6°F, the same as your body temperature. Coffee can be as hot as 185°F when fresh. Due to the temperature differential between your breath and the hot coffee, we’re able to achieve a reasonable amount of cooling just by simply blowing across the surface. Typically, when the target temperature of the part or material needs to be around ambient temperature or higher; the best solution for cooling is going to be a Super Air Amplifier.

EXAIR’s Super Air Amplifiers achieve air amplification ratios ranging from 12:1 on our smallest units and up to 25:1 for our 4” and 8” models. EXAIR’s Super Air Amplifiers utilize a patented shim design to maintain critical positioning of component parts. This allows a precise amount of compressed air to be released at exact intervals toward the center of the Super Air Amplifier. This creates a constant, high velocity outlet flow across the entire cross-sectional area. Free, ambient air is entrained through the unit, resulting in high amplification ratios. The balanced outlet airflow minimizes wind shear to produce sound levels far lower than other similar air movers.

Super Air Amplifiers are supplied with a .003” thick shim that is ideal for most applications. Flow and force can be increased by replacing the shim with a thicker .006” or .009” shim. The flow of air is also controlled by adjusting the input pressure supplied to the amplifier. Higher pressures increase both the force and flow, while lower pressures decrease both force and flow. All Super Air Amplifiers are available in kits that come with a shim set as well as a suitably sized pressure regulator and auto-drain filter.

EXAIR has a solution for you if you need to move A LOT of air. Reach out to an Application Engineer today if you have an application that you believe could be served with a low-cost, simple solution!

Pneumatics: Top 10 Advantages of EXAIR Compressed Air Products

Pneumatics is a branch of engineering that makes use of gas or compressed air. The word pneumatic is derived from the Greek words πνεῦμα pneuma and means wind breath. With 9 out of 10 industries utilizing compressed air products and processes, we could say that pneumatics are the “breath” of industry. OK, I may be stretching here, but it it does flow well…

At EXAIR, we pride ourselves on using compressed air intelligently. Nearly all of our products utilize compressed air and maximize it’s efficiency. Let’s take a deep breath and look at some of the reasons why “wind breath”, and more importantly why the EXAIR products are so advantageous in industry.

REASONS TO USE COMPRESSED AIR

PNEUMATICS

  1. There is an infinite supply of air on this planet to be compressed and used. I know this seems obvious but what other energy source has an infinite supply?
  2. There are very low maintenance costs with pneumatic tools. Our products have minimal to no moving parts. There is no motor to repair, no oil to change, no bearings or fans.
  3. Our products are engineered to be easily installed and can be adjusted for performance. Most of the time you simply mount the product and add air. A simple pressure regulator provides a huge bandwidth of adjustment to dial in the force and performance.
  4. Air is very easy to transport. With your current compressor system, you can easily run pipe to the point of use and supply the products with their power source.
  5. Compressed air is compact, and usually takes up less space to install a compressed air product.
  6. Our products and tools are extremely reliable. Due to the precision engineering and production, our products produce a repeatable result every time they are turned on.
  7. EXAIR products all comply with OSHA standards for sound (29 CFR 1910-242 (b)) as well as dead end pressure 29 CFR-1910.95(a)).
  8. Initial purchase as well as installation costs are typically considerably lower than non pneumatic options. When you add in the upkeep and maintenance, EXAIR products are almost always less expensive than alternative products.
  9. Using compressed air as your power supply typically facilitates a cleaner, dryer, safer work environment.
  10. At EXAIR, you have a team of application engineers at your fingertips that will help you choose the best product for your specific application. Feel free to call or email at anytime.

Understanding EXAIR Air Amplifiers and Air Pressure Amplifiers

Adjustable Air Amplifier

I take many calls regarding Air Amplifiers but sometimes I get calls that confuse EXAIR Air Amplifiers with air pressure amplifiers. EXAIR’s Air Amplifiers and air pressure amplifiers are fundamentally different and have different purposes.

First, EXAIR’s Super Air Amplifiers and Adjustable Air Amplifiers increase air volume, not pressure. Air pressure amplifiers increase air pressure from typical system pressure of 80-130PSIG up to 5000 PSIG. Air pressure amplifiers are an excellent solution for applications that require higher air or nitrogen pressure such as increasing force for clamps or presses and pressure testing processes. They are also known as air boosters.

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

EXAIR Air Amplifiers are a low cost way to move air, smoke, fumes and light materials. These Air Amplifiers use the Coanda effect to create a low pressure area which draws in surrounding air to efficiently deliver a high volume of air on to a target. Using a small amount of compressed air as their source, Air Amplifiers are among the most efficient products within EXAIR’s entire product line. EXAIR Air Amplifiers will create output flows up to 25 times their consumption rate and deliver it at a high velocity. The entrainment of outside air amplifies the total volume of air output which also increases force, cooling ability and circulation.

EXAIRs Air Amplifiers have no moving parts, assuring maintenance-free operation. Fine tuning flow, vacuum and velocity are easily controlled by regulating the pressure. For gross adjustment of air flow and vacuum an internal shim is used to increase or decrease the internal “air gap” that the compressed air flows through. 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.

I hope this helps distinguish EXAIR Air Amplifiers versus air pressure amplifiers. If you have questions regarding EXAIR Intelligent Air Products please contact one of our Application Engineers as we are always ready to help.
