Super Air Amplifier Provides Needed Ventilation

Behold: The Power of the Microwave!!!

Over the weekend, my wife and I were doing some “re-organizing” upstairs (actually throwing away some old toys and clothes), when our son decided to make a snack. I heard the pantry door close so I asked, “hey bud, what are you doing down there?”  He promptly replied, “I’m just making a snack dad. How long do you normally microwave my soup?” While we questioned making soup at 9:00 AM for a snack, I reluctantly replied 2 minutes and heard the microwave begin. Slowly, a strange (awful) odor started to fill the house so I went downstairs to investigate. To my horror, I opened the microwave door to discover that he wasn’t making a snack for him, he was actually heating up a can of dog food, so his partner in crime (our dog), “could have a warm meal like us”.  I immediately took the snack to the garbage outside and attempted to remove the stench from the house. I opened a couple windows and turned on the stove exhaust but this was still not working. That’s when I started thinking it sure would be nice to have a Super Air Amplifier handy, to help evacuate some of the odor and make the house livable again.

Using a small amount of compressed air, the Super Air Amplifier entrains a large volume of surrounding air and pulls this air through the unit, resulting in a high velocity, high volume of air on the exhaust side. The intake, or vacuum, side of the Super Air Amplifier pulls in 25 parts of surrounding air for every one part of compressed air. This high volume of ambient air being moved makes the Super Air Amplifier ideal for venting and exhaust applications.

Additionally, the vacuum and exhaust ends can be ducted, which makes this a good product for moving air from one place to another or from inside to outside. They are used in many applications for assisting air circulation and available in styles which are placed in ovens (and other high temp areas), corrosive environments, and remote locations. With the large volumes of air being moved, they are also an ideal choice where cooling and drying is required.

Our Air Amplifiers entrain enormous amounts of "free" air, at ratios of up to 25:1!
The Super Air Amplifier entrains large amounts of surrounding air, at ratios of up to 25:1.

Air Amplifiers are some of the most efficient products in the extensive EXAIR line of compressed air products. They use a patented internal shim to minimize air consumption and increase air volume on the output side. The operate exceptionally quiet, are OSHA safe and CE compliant.

If you have a ventilation or fume exhausting application, please contact an application engineer for assistance.

Super Air Amplifier Removes Fumes In Plastics Machining

Published on by exaircorpLeave a comment

I recently took a call from a customer who was using our Model # 120022, 2″ Super Air Amplifier to remove an odor that is produced from trimming their plastic pump impellers. The impellers are made of carbon fiber reinforced plastic and when they turn the larger impellers the Super Air Amplifier “works great”. The fumes are captured by the amplifier and exhausted through 10′ of duct attached to the positive pressure side of the amplifier. However, as they increase the speed to trim the smaller sizes, the amount of fumes would increase and remain in the area, so they called EXAIR for help.

Using the Coanda profile, the Super Air Amplifier utilizes a small amount of compressed air to induce a large amount of surrounding ambient air and directs it into the primary airstream. The surrounding ambient air is pulled into the Super Air Amplifier from the large diameter (vacuum side) to the small diameter (positive pressure side). The result is a large volume of outlet airflow, making them the ideal choice for this type of application. While the units are shipped with a .003″ shim installed, we offer both a .006″ or a .009″ shim (available in a Shim Set) that allows you to increase the gap, resulting in more volume of vacuum and positive pressure flow, and force.

I recommended the customer order the Shim Set, allowing them to increase the gap to induce a larger amount of air to evacuate the area. They are now using one unit, capable of handling both jobs.

If you have a similar application or need help with your existing Air Amplifier, give us a call!

Special Air Amplifier? Not A Problem!

Published on by Dave WoernerLeave a comment

This week I worked with two customers that wanted to boost their air flow with an Air Amplifier. One customer ended up going with a Special Air Amplifier. The second customer I ended up pointing to a different product line entirely. Keep reading to find out why.

The first customer needed to boost the exhaust flow through six inch duct.  The six inch duct was an open vent that allowed fumes to slowly escape from a vessel. During normal operation the vessel, was unmanned, so the fumes only need a path to escape, but could linger. The company wanted to do some maintenance work in the area while the machine was in operation. The vent met the necessary requirements for the air flow of the machinery, but left maintenance workers exposed to a variety of fumes while working in the vessel, if the unit was in operation.

The customer was interested in the model 6034 Stainless Steel Air Amplifier. With 0.002″ air gap and 80 PSIG of inlet pressure, the unit will flow 1,200 SCFM of compressed air at the outlet of the Air Amplifier, but the 6034 can be adjusted to much higher flows from there.  The Air Amplifier would easily be able to exhaust the fumes from the area to maintain a safe and comfortable working environment. The problem was mounting the 6034 Adjustable Air Amplifier. The 6034 is designed to be used in free air with the discharge side of the air amplifier connecting to a duct. The suction side of the Air Amplifier is as open as possible to entrain air, but my customer needed to connect the Air Amplifier to the outlet of the vent. We worked with the customer on designing an Air Amplifier to fit the 6″ Flange that they used to connect sections of their duct similar to the Air Amplifier pictured below.

This special stainless steel flange-mount Air Amplifier was designed for exhausting hot flue gases from a furnace.

My other customer called to move the air inside a heated drying tunnel. The customer uses a process air heater to heat a large drying tunnel. Unfortunately, the air heater created hot air at the entrance of the drying tunnel. By the time the air reached the end of the drying tunnel the temperature was significantly higher at the top of the tunnel as opposed to the bottom from natural convection. To counter this effect the customer wanted to move air from the process heater half way down the tunnel and release the air. In this application, the customer wanted to duct both the inlet and the outlet of an Air Amplifier. The Air Amplifier is not well suited for ducting and you limit the amount of air that the Air Amplifier can entrain by connecting it to a duct.

For this customer, I recommended he use a Line Vac. The Line Vac typically conveys materials, but it will also move a good amount of air.  The customer was going to use heated compressed air and wanted to convey the air from the process heater to the other side of the drying tunnel. Another key benefit to the Line Vac is the discharge and suction side of the units are both the same size.  This makes it extremely easy to install for the customer and is off the shelf, ready to ship.

Two similar applications on the surface that result in different product recommendation. Not every application for an air mover is this complicated, but if you want to talk through your application EXAIR’s application engineer’s will be happy to help.
