How Air Amplifiers Work |
|
![]() |
|
Compressed air flows through the air inlet (1) into an annular chamber (2). It is then throttled through a small ring nozzle (3) at high velocity. This primary airstream adheres to the Coanda profile (4), which directs it toward the outlet. A low pressure area is created at the center (5), inducing a high volume flow of surrounding air into the primary airstream. The combined flow of primary and surrounding air exhausts from the Air Amplifier in a high volume, high velocity flow. |

How to Determine High Temperature Air Amplifier Total Output Flow and Air Consumption |
|||||
![]() |
|||||
Total Airflow: From the performance curves (above), determine total output flow for any Super Air Amplifier at any pressure. Example: A Model 120021 at 60 PSIG (4.1 BAR) supply air pressure has a total output flow of 120 SCFM (3,398 SLPM). Air Consumption: Divide total output flow by the amplification ratio to determine air consumption for any Super Air Amplifier at any air pressure. In the example above, the Model 120021 at 60 PSIG (4.1 BAR) supply air pressure has a total output flow of 120 SCFM (3,398 SLPM). Dividing this total output flow by its amplification ratio of 18 gives an air consumption of 6.7 SCFM (189 SLPM). |

Special Air Amplifiers
EXAIR will manufacture special Air Amplifiers suited to your specific application requirements. The Model 121021 High Temperature Air Amplifier was developed for moving hot air to surfaces requiring uniform heating while in a furnace or oven. Modeled after our Super Air Amplifier, the High Temperature Air Amplifier is the most efficient for pushing high volumes of hot air to points that typically remain cool. This special design is rated for environments up to 700°F (374°C) and its surface is protected from heat stress by a mil-spec. coating process (developed for the aircraft industry), allowing easy disassembly for changing shims or cleaning.
Another stainless steel version for flange mounting was developed as a fan back-up for exhausting flue gases from a furnace. In the event of a power failure, this special Air Amplifier can quickly evacuate the fumes that could be harmful to workers close by.
A PTFE plug was used with a stainless steel Adjustable Air Amplifier to help pull a sticky material through a process and prevent the material from depositing on the Air Amplifier. EXAIR's Intelligent Compressed Air® products can be manufactured to your special requirements.
If you have special requirements, please contact an Application Engineer to discuss it.
Blowoff on a Transmission Pan
The Problem: A newly designed transmission pan presented a myriad of cleaning problems for the die-caster. Because the configuration included channels and blind holes as well as smooth surfaces, a “shaped” air pattern was required for proper cleaning. No single blowoff product would fit the need. An assortment of open copper tubes and drilled pipes was considered, but was rejected as too noisy and expensive to operate. A blower was not an option due to the high purchase price, expensive maintenance costs and frequent downtime.
The Solution: With help from our Application Engineers, the company created a cleaning system incorporating a variety of EXAIR blowoff products. (2) Model 6013 High Velocity Air Jets, with their confined airstream, cleared the blind holes, while (2) Model 120022 2" (51mm) Super Air Amplifiers cleaned the channels. A Model 2012 12" (305mm) Standard Air Knife was positioned to blow out the casting’s underside.
Comment: There’s no doubt that the casting could have been cleaned just as well by hooking up a bunch of open copper tubes and throwing a ton of air at it. But, at what cost? EXAIR makes a variety of blowoff products because parts come in a variety of shapes and sizes. And, our products operate at a fraction of the air consumption and noise levels associated with open air jets. When you need to clean, cool, or dry with air, and you’d like to minimize dollars and decibels, EXAIR can help.
Super Air Amplifier Cools Iron Castings
The Problem: A foundry that produces iron castings for the automotive industry had a problem with certain hot parts that slowed their production. After pouring, the castings gradually cool by traveling along a 200 foot long conveyor. At the end, a shake-out conveyor breaks the sand mold so the casting can be removed. Normally, the operator could pick up the part with special gloves and grind the rough edges. However, some castings such as crankshafts, differential housings, and shift parts retained too much heat, making them too hot to handle. The operator had to wait up to ten minutes for them to cool.
The Solution: They installed (5) Model 120022 2" (51mm) Super Air Amplifiers over the shakeout conveyor. The high output airflow from each Super Air Amplifier rapidly cooled the parts without shocking them (no cracks or imperfections from cooling too rapidly). When the part reached the end of the conveyor, the operator could proceed immediately. The backlog was completely eliminated.
Comment: This manufacturer had almost given up on finding a cooling solution since the fans and blowers that were tried in the past showed little improvement. Our Super Air Amplifier dramatically reduced the cooling time. As a result, they installed them on their second line. The low cost Super Air Amplifiers are compact, portable and have no moving parts to wear out (which is ideal in a dusty foundry). And, the patented design assures the highest output air volumes possible with the lowest air consumption.
Roaring banana breath
The Problem: A company that designs major attractions for theme parks created a huge gorilla to startle the patrons. The animators wanted the oversized ape to appear as “life-like” as possible. To accomplish this, they used a series of motors and cylinders to make the movement of the eyes, hands, arms and torso appear realistic. They also installed a large speaker system to play an audio sample of a loud roar that matched his mammoth size. The finishing touch was to find a way to create a powerful blast of air that smelled like bananas each time the big ape's mouth opened. Attempts using an electrically powered blower Roaring Banana Breath proved unsuccessful due to the noise and the inability to obtain an “instant on” blast of air.
The Solution: They installed a tank of banana extract in his tummy and connected it to his mouth with a Model 120028 8" (203mm) Super Air Amplifier. As the spectators moved into position, a sensor activated the electronics, setting “Old Banana Breath” (name given by the designers) into motion. With a swift movement toward the crowd, his mouth opens and the Super Air Amplifier provides an instantaneous blast of high velocity air (filled with banana fumes) at them.
Comment: Why did the engineers select the Super Air Amplifier? First, simplicity. There are no moving parts to wear out or require maintenance. It uses only filtered compressed air as the power source. Second is the big instantaneous blast of high volume, high velocity airflow that couldn't be obtained using a blower or air nozzles. When it comes to special effects, Super Air Amplifiers are the way to go. When you watch the movies or visit the theme parks and see fast moving fog, smoke effects, or objects flying through the air, chances are a Super Air Amplifier is being used.
Cleaning Brake Rotors
The Problem: An automotive machine shop that manufactures brake rotors was having problems with chip build-up inside the part. They tried compressed air tubing flattened on their ends with little success. This resulted in high compressed air usage, high sound levels, and danger to their employees.
The Solution: A Model 120021 1-1/4" (32mm) Super Air Amplifier was substituted for the tubing. It provided a larger pattern of air, used less compressed air, the sound level was substantially lower, and it couldn't be deadended.
Comment: Bent tubing or drilled pipe are inexpensive and easy to make. However, the initial cost is overshadowed by its high energy use; holes can be blocked and noise level is excessive – both of which are OSHA violations. EXAIR’s Super Air Amplifiers are compact and dependable since there are no parts to wear out. Our patented design moves the most airflow possible while using the smallest amount of compressed air. The lower sound level was another bonus!
