Wirco's High-Temperature Furnace Fans can be found in most heat treatment furnaces except for vacuum furnaces, circulating air or gas at temperatures exceeding 1,000°F (540°C). By maintaining consistent heat flow, they prevent hot spots and ensure that every product is treated evenly, whether it’s hardening, annealing, or tempering. A reliable furnace fan directly impacts product quality, production speed, and operational costs.

Since they work in such an extreme environment, heat treat fans require ongoing repair and furnace fan replacement to maintain performance. Wirco is known for having the highest quality fans, which maintain their balance and require less frequent replacement. For customers seeking furnace fan replacement in their heat treat furnaces, Wirco provides expert solutions to ensure minimal downtime and maximum reliability. We also produce air-cooled fan housings that hold fans in place on the top or sides of the heat-treating furnaces. Reliability and reducing downtime are the keys to Wirco’s fan success.
