Model Overview

SDBD and SDBDe direct drive fans are designed to exhaust air up to 4,980 CFM, with high static pressure capability up to 1-1/2". 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. Direct drive units use smaller diameter wheels, resulting in low sound levels and quiet operation. They have no belts or fan bearings to maintain or adjust and consequently require very little maintenance. Its roof mounting permits short duct runs and more efficient operation.

SDBD and SDBDe are generally used to exhaust air from all types of commercial and institutional buildings such as hospitals and healthcare facilities, schools, recreational buildings, machinery and equipment rooms, offices, retail stores and similar applications.
