High‑temperature fans are specialized equipment designed for use in high‑temperature environments, with materials that offer excellent resistance to both high temperatures and high pressures. The main types of high‑temperature fans include stainless steel high‑temperature fans, geared high‑temperature fans, and centrifugal high‑temperature fans.

　　High-temperature fans are specialized blowers designed for high-temperature applications, typically operating at temperatures ranging from 100 to 180°C. They are widely used in the boiler and drying industries.

　　High-temperature fans are widely used in the chemical industry, petroleum, metallurgy, forging and pressing, power generation, nuclear power plants, environmental protection, and other fields.

　　1. The high-temperature fan primarily consists of an impeller, a casing, an air inlet, an electric motor, connectors, and cooling fan blades.

　　2. The impeller is a multi‑blade, single‑inlet centrifugal type, fabricated from high‑quality galvanized sheet or cold‑rolled steel plate, with blades designed according to aerodynamic principles. It consists of ten backward‑curved airfoil blades, a curved front disc, and a flat rear disc. The material is made from premium steel that offers high strength and excellent durability, and the impeller has undergone rigorous dynamic and static balancing. It delivers superior airflow performance, high efficiency, and smooth operation.

　　3. The air inlet adopts a convergent streamline design to reduce vortex formation, resulting in minimal airflow losses and high operational efficiency for the high-temperature fan.

　　4. The high-temperature fan housing is integrally mounted to the motor via a metal casting, with cooling fins installed on the motor shaft head. Inlet and outlet water pipe connections are provided on the outer surface of the metal casting to dissipate heat from both the casting and the shaft head, ensuring the motor operates reliably under high-temperature conditions.

　　5. The motor is a specialized high-temperature model, and the fluid‑contacting components of the high‑temperature fan are made from heat‑resistant materials, ensuring a reliable cooling design. Compared with other boiler induced draft fans, it offers advantages such as a simple structure, easy maintenance, and excellent cost‑effectiveness.

　　Installation type

　　1. This high-temperature fan is available in two configurations. When viewed from the motor side, if the impeller rotates clockwise, it is designated as a right-hand rotating fan and marked with “R”; if the impeller rotates counterclockwise, it is designated as a left-hand rotating fan and marked with “L”.

　　2. The outlet position of the high-temperature fan is indicated by the angle of the casing’s discharge port. Fans in sizes №1.5 to 6 are supplied from the factory in an adjustable configuration; the user can install them at the desired orientation according to specific requirements. The adjustment range for the discharge port position is 0° to 255°, with increments of 45°. All units are driven via a direct‑drive “A” type coupling.
