high-temperature air supply fan

High-temperature air supply fans move preheated air into ovens, dryers, and heat-treatment chambers. Impellers and casings are made from Inconel or stainless steel alloys rated for up to 450 °C.

These fans provide 2,000–30,000 CFM at static pressures up to 5 kPa. Motors are protected by water-cooled jackets or remote drive arrangements to keep electrical components below their maximum rating.

Variable frequency drives (VFDs) enable temperature-responsive supply, adjusting airflow based on chamber thermocouples to maintain precise process conditions and improve product quality.

Maintenance features include split-casing for impeller removal, external lubrication ports, and monitoring of motor winding temperature. High-temperature air supply fans ensure safe, efficient delivery of hot air in demanding thermal processes.
