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.
