In this Calciner Tempering installation, we retrofitted backward-curved blowers to replace our customer’s existing fans for increased efficiency and longer fan life. Using 300 HP customer-supplied motors, we incorporated a flexible coupling drive, unitary base, and pie-split housing for easier maintenance access to the fan wheel and shaft.
Application: Tempering
Designed for cooling during glass tempering operations, this Arrangement 3 backward inclined cooling fan has bearings on either side of the wheel with a unitary base and a double-width housing for higher airflow capacity. This application includes spring vibration isolators and screens on both fan inlets.
AirPro received the OEM order for four tempering blowers built for a glass manufacturer here in our home state of Wisconsin. The fans are installed on the back end of the glass oven, providing supply air for the tempering process.
