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, when the temperature differential between the Super Air Amplifier’s airflow and the temperature of the part is significant. Due to their ability to entrain large amounts of ambient air, we can move a lot of 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 hot part or material needs to be around ambient temperature or higher, a Super Air Amplifier can be a good choice.
While many applications utilize the outlet flow of the Super Air Amplifier to blow off, clean or cool a part or material, the ability of the Super Air Amplifier to entrain large amounts of ambient air can also be utilized to convey light materials or to draw in dust, smoke, or fumes from the surrounding environment. As the plugs on the exhaust side of the Super Air Amplifiers come in sizes of ¾”, 1-1/4”, 2”, 4”, and 8” the exhaust flow can be ducted with standard size hose.
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!
