We blog about this topic quite a bit, and almost every section of our catalog has a page set aside just for special / custom product configurations that have been created by request from many of our customers.
This is the latest and greatest special that I have seen roll through the production area here at EXAIR. This is a special 4″ 303 Stainless Steel Adjustable Air Amplifier with a 4″ Tri-Clamp flange on the discharge side and a 6″ Tri-Clamp flange on the suction side of the amplifier.
This had been an ongoing project with the customer that started with them testing a stock Adjustable Air Amplifier in the application to ensure that the performance would meet their needs. The application was to boost a low flowing fume exhaust that was causing slow downs in their production line. Fans and other traditional methods would require maintenance and would wear out. The stock Adj. Air Amplifiers exceeded their performance needs but did not easily mount into their duct work because they used all standard size tri-clamp fitting in the ducting, so the next step was to see if we could manufacture a Special Adjustable Air Amplifier just for their needs. The dimensions of the existing Adjustable Air Amplifier came close enough we were able to easily create a Flanged Adjsutable Air Amplifier that would clamp straight into their existing duct work, exceed their performance expectations, help their process, and be ready to ship within a very reasonable lead time.
Like we have said before, if a stock, cataloged, product doesn’t fit your application exactly, contact us and let us find a way to customize and fit the need.
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.
