High temperature fans can be used for a wide variety of applications ranging in temperature from 650-980°C, with higher temperatures available where required. AirEng can design and manufacture both centrifugal and axial high temperature fans in sizes from 305-2130mm in diameter. Centrifugal fans are available in both forward-curved and paddlewheel configurations, and axial fans are available in both one-directional and reversible configurations.
Depending on the application requirements, our high temperature fans are typically constructed from 316 stainless steel for temperatures up to 815°C. Fans operating at even higher temperatures up to 980°C are generally constructed from a 309, 800H, 625, 617 Haynes 230, or Super 22H alloy.
High temperature fan accessories include insulation between alloy hot surfaces and mild steel cold surfaces, packing glad shaft seals, water-cooled, shaft, heat slingers, and/or flowing construction to accommodate thermal growth. We have experience delivering rugged, reliable solutions for high temperature applications in industries such as aluminium, steel, copper, carbon/charcoal, waste incineration, and more.
