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.
The backward inclined fan has flat backward inclined blades to minimize airflow interference for high efficiency with lower sound levels and energy costs than other fan types.
Tempered glass is used in industries including automotive, building materials, and furniture for safety so that it does not shatter even if broken. Glass tempering operations use a furnace to heat the glass to the annealing point, meaning above its upper critical temperature. It then uses forced draft air to rapidly cool the glass with a uniform cold airflow.
