High-temperature fans typically tolerate a broad range of temperatures, depending on design, materials, and manufacturer. Here are some common maximum temperatures for these fans:

Below 150°C: General high temperature fans can endure this low limit for general heating purposes such as printing or drying.

Between 150°C-200°C: Middle-grade ones can cope with these temperatures for medium heating applications like chemical processing, food production, etc.

Between 200°C-250°C: High-grade ones can withstand these upper ranges for high heat requirements like steel manufacturing, refractory materials, etc.

Above 250°C-850°C: Super high temperature fans can handle these extreme conditions for extremely high heat needs like high-temperature furnaces, high-temperature treatments, etc.

Please note that these temperature ranges are approximate and may vary based on specific fan designs and manufacturers. When choosing your high temperature fan, consider your application specifics and consult with the supplier to confirm the actual tolerance limits.
