We recently worked with a customer that manufactures mirrors for the automotive industry. Today’s mirrors are evolving and becoming more and more complex, including functions such as auto-dimming, and navigation and backup camera display.
Mirror manufacturing involves many steps, one step is the application of the reflective material. Silver can be deposited chemically, but other materials such as aluminum and gold, and for scientific grade mirrors, silicon oxides and silicon nitrides are applied via an evaporative process within a vacuum chamber. The metal is heated under the condition of vacuum until it vaporizes and is then deposited on the glass. Many layers may be deposited depending on the mirror type and reflective properties desired.
Our customer came to us and said they were interested in utilizing the Super Air Amplifier technology in the glass cooling process. After reviewing all of the details of the application, including the ambient temperature conditions, we recommended the EXAIR High Temperature Air Amplifier, model 121021, as the right choice for the cooling application.
The model 121021 High Temperature Air Amplifier was developed for moving hot air and to be able withstand high temperature ambient conditions. This special design is rated for environments up to 700°F and its surface is protected from heat stress by a mil-spec coating process developed for the aircraft industry. It uses just 8.1 SCFM of 80 PSIG compressed air, has an amplification ration of 18:1, and a sound level of only 72 dBA. This highly efficient and quiet air amplifier was the right choice, and the customer has reported back that they ‘have been working good’ in the application. They are also used to circulate hot air in ovens or keep even temperatures on large rotational molds. They also solve heat/cooling problems in glass manufacturing, primary metals, heat treating and power generation. They are the right choice for rugged, high temperature processes.
EXAIR makes other specialty Air Amplifiers, including models made for specific customer applications. These include designs with flange mounting for exhausting flue gases from a furnace and a design with a PTFE plug to help pull sticky material through a process while preventing the material from depositing on the Air Amplifier.
