S&P USA SDBD10MM1AS - Downblast Direct Drive Centrifugal Roof Exhauster

This SDBD direct drive fan is designed to exhaust air up to 949 CFM. The non-overloading backward inclined wheel with its higher static pressure capability makes these units suitable for either ducted or non-ducted applications. The spun aluminum exterior provides an attractive appearance and is compatible with belt driven Model SDB and companion gravity units to make up a complete ventilation system.
