High temperature fans are used in many systems for different purposes, such as the ventilation of ovens, stoves, and fireplaces. The purpose of a high-temperature fan depends on its design and assigned functions.
High-temperature fans (they are also called heat-resistant) can be of axial or centrifugal design. The working environment of such fans can be hot and aggressive. Most often, they are used in ventilation ducts but there are designs of heat-resistant fans that are used without air ducts.
