Centrifugal Blower for Hot Air Application
A Centrifugal Blower for Hot Air Application is an industrial-grade fan designed to move heated air or gases efficiently across various heating processes. Built to withstand high temperatures and continuous operation, these blowers are essential for maintaining air circulation in thermal systems. Their ability to deliver high-pressure airflow makes them indispensable in industries where hot air transfer, drying, and ventilation are critical.
Description
Centrifugal blowers operate by using a rotating impeller to increase the velocity of air and direct it through a discharge outlet at high pressure. In hot air applications, the blower is specifically designed with temperature-resistant materials, insulated housings, and high-temperature bearings to handle air temperatures ranging from 80°C to 400°C or more.
These blowers are available in single inlet single width (SISW) or double inlet types and can be powered by direct drive or belt-driven motors, depending on airflow requirements.
