Last week, a customer called in to talk about their application. After aluminum and steel machining operations, parts are run through a washer system. The drying portion utilized a Super Air Amplifier to dry the sides and a Super Air Knife to dry off the top. The wash temperature was running at 185°F. The customer wanted to review the application and make sure the EXAIR products utilized in the process were rated to this temperature and to check on high the products could go, since the maximum possible temperature for the washer was listed as 250 °F.
The Super Air Amplifier is rated to 275°, above the maximum possible condition. The Super Air Knife was pre-installed with a stainless steel shim, enabling a maximum temperature rating of 400 °F. Both of the components are rated for temperatures in excess of the maximum possible washer temperature condition, and the customer felt confident with the system design.
EXAIR has several options in the Air Amplifier and Super Air Knife product families to allow for operation in high temperature applications. For the Air Amplifier, the Super Air Amplifier and Aluminum Adjustable Air Amplifier have a maximum temperature rating of 275°F. The Stainless Steel Adjustable Air Amplifier is rated to 400°F, and for the hottest of conditions, the High Temperature Air Amplifier is rated to 700°F.
Relating to Super Air Knife, the aluminum Super Air Knife is rated to 180°F. With a stainless steel shim installed, the maximum increases to 400°F. The PVDF Super Air Knife, used in applications where chemical resistance is needed, can withstand temperatures up to 275°F. And for the most extreme temperature environments, the Type 303 and Type 316 Stainless Steel Super Air Knives are rated up to 800°F.
To discuss your application and how an Air Amplifier and Super Air Knife or any EXAIR Intelligent Compressed Air Product can help your process, feel free to contact EXAIR and one of our Application Engineers can help you determine the best solution.
