Hot Air Ventilation Axial Fan
Description:
A Hot Air Ventilation Axial Fan is a type of industrial air-moving device designed to move large volumes of hot air efficiently through ventilation systems. It works on the axial principle, where air flows parallel to the shaft of the fan, making it ideal for forced ventilation, heat dissipation, and air circulation in high-temperature environments.
Axial fans used for hot air are typically built with heat-resistant components, enabling them to operate in temperatures ranging from 80°C to over 250°C, depending on the application.
