EXAIR Air Amplifiers Blow Fans out of the Water!

Published on by Jordan T ShouseLeave a comment

EXAIR’s product line contains many products that can be used for cooling. The focus of this blog will be Super Air Amplifiers. These often times get placed in a head-to-head competition with an electric fan. The best part, they easily come out on top.

When looking at the benefits other than performance and rate of cooling due to air entrainment, many customers prefer the Super Air Amplifier due to the fact there are no moving parts. This comes into play when cooling within in a hard-to-reach area or within a harsh process is needed.  Placing an electric motor with a blade held on by fasteners may not be desirable from a maintenance standpoint. The Super Air Amplifiers do not require electricity and there is not a motor or bearings that would need to be replaced or inspected.

Another benefit is the small footprint of the Super Air Amplifier. This can also be seen within the video below where the Air Amplifier is shown is able to produce 341 SCFM (9,650 SLPM) in amplified airflow. Compared to the fan in the video, the amplifier is less than a 1/4 of the size but outperforms the fan in cooling the metal block! This allows users to place a small unit inside a tight area or chamber that requires large volumes of air.  For instance, a rotomolded part that has a large chamber, and it needs surfaces to be cooled in order for the part to hold its shape from the mold rather than warp.  This can also be coupled with the fact that a Super Air Amplifier can be ducted on either the suction or discharge side in order to retrieve cool air or move the warm air out of the area.

Speaking of warm, the Super Air Amplifiers are also manufactured to withstand up to 275 °F (135 °C) from stock.  Stainless Steel and High-temperature models go well beyond that temp, up to 700 °F (374 °C). Custom-designed (flanges and different materials are common) versions are also available with short lead-times.

Super Air Amplifiers vs. Electric Fans

Our own Tyler Daniel produced a great video showcasing how efficient it is to cool a part using the Super Air Amplifier rather than a fan.

A Unique Application for the Ultrasonic Leak Detector

Published on by Tyler DanielLeave a comment

Here on the EXAIR blog we post a ton of different applications for our products. We typically see similar applications each day and write about them so that you may identify potential points in your various processes that may benefit from an engineered compressed air solution. Many of these are typical blowoff or cooling applications that we see day in and day out. Sometimes, though, we see some applications that are outside the realm of typical operation. This can sometimes require the manufacturing of a specialized part or just getting a little creative with a stock product.

Our distributor in Argentina recently contacted me about a unique application for an Ultrasonic Leak Detector. The Model 9061 Ultrasonic Leak Detector is a hand-held instrument that allows you to locate costly leaks in a compressed air distribution system. As pressurized air exits a small orifice, an ultrasonic sound that is above human hearing is created. The Ultrasonic Leak Detector is able to pick up on these sound emissions and can convert it to an audible range that is able to be heard by the human ear. Typically, this product is used in conjunction with a leak prevention program to help save money and compressed air by identifying leaks in the distribution system.

Model 9061 ULD detecting a leak

The customer is a manufacturer of plastic bottles used to hold a wide variety of different personal care products. The bottles were molded in two separate pieces, then brought together and sealed. After the two pieces of the bottle were sealed, they had to test each one to ensure that they remained watertight. Their current method involved filling the cavities with water and inspecting for leaks.

While this method was effective, when a leak was present water would get all over the machine and floor and needed to be cleaned up. This to them was considered a nuisance and they began to explore alternative methods of checking the seals on the bottles. They found EXAIR’s Ultrasonic Leak Detector and wondered if they could use it to detect leaks on the bottles if they were to pressurize them with compressed air instead of filling them with water. We’ve handled similar applications in the past, this one here a customer used the ULD to detect leaks from poor welds on the roof of buses. They ordered one for testing and were very pleased with the results. The ULD had no problem detecting leaks in the bottles and allowed them to eliminate the mess and annoyance associated with using water.

Just because you can’t find a particular application in our Application Database on the website or here on the blog, doesn’t mean that it can’t be done! With our unconditional 30 day guarantee for all stock products you have plenty of time to test it out in your specific application. If for any reason it won’t work for you, just send it back and we’ll try something else.

If you have a unique application that could be served by an Intelligent Compressed Air Product, give us a call. Trust me when I say we absolutely LOVE tackling a new and exciting challenge with a creative solution!
