Centrifugal Roof & Wall Fans
SDBD and SDBDe
Downblast Direct Drive Centrifugal Roof Exhaust Fans
SDBD and SDBDe direct drive fans are designed to exhaust air up to 4,984 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. 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.

SDB
Belt Drive Centrifugal Downblast Roof Exhaust Fan
The SDB belt drive fans are designed to exhaust air up to 31,563 CFM in high static pressure applications up to 1-3/4". The aluminum exterior provides an attractive appearance. Belt drive results in lower operating RPM and sound levels, making the Model SDB well suited to applications where quiet operation is important. Belt drive also permits easy performance adjustments when needed to balance the total ventilation system. The non-overloading backward inclined wheel with its higher static pressure capability makes this unit suitable for either ducted or non-ducted applications. Its roof mounting permits location near the area to be ventilated, allowing short duct runs and more efficient operation.

CWD
Direct Drive Centrifugal Sidewall Exhaust Fan
Centrifugal Wall Mounted Exhauster Direct Drive Fans (CWD) is designed to exhaust air up to 3,360 CFM, with high static pressure capability up to 1". The spun aluminum exterior provides a pleasing appearance, weatherproof construction, and resistance to corrosion. The low silhouette design is less noticeable on the building exterior, and the removable dome provides easy access to the fan interior for service and cleaning. The non-overloading backward inclined centrifugal wheel with its high static pressure capability makes it suitable for either ducted or non-ducted applications. It should be used where a sidewall mounted location is preferred to roof mounting. Direct drive units use smaller diameter wheels with lower RPM's, resulting in low sound levels and quieter operation. They have no belts or fan bearings to maintain or adjust and consequently require very little maintenance.
