MODELS SDBD & SDB
DIRECT DRIVE AND BELT DRIVE CENTRIFUGAL
DOWNBLAST ROOF EXHAUSTERS
MODEL OVERVIEW
Model SDBD direct drive fans are designed to exhaust air up to 4,980 CFM in high static pressure
applications to 1-1/2”. The spun aluminum exterior provides an attractive appearance. The non-overloading
backward inclined wheel with its higher static pressure capability makes this unit suitable for either ducted
or nonducted applications. Its roof mounting permits location near the area to be ventilated, allowing short
duct runs and more efcient operation.
The SDBD is generally used to exhaust air from all types of commercial and institutional buildings
such as hospitals and health care facilities, schools, recreational buildings, machinery and equipment
rooms, ofces, retail stores and similar applications.

MODEL OVERVIEW
Model SDB belt drive fans are designed to exhaust air up to 4,135 CFM in high static pressure
applications to 1-1/2”. 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 nonducted applications. It’s roof
mounting permits location near the area to be ventilated, allowing
short duct runs and more efcient operation.
SDBs are primarily used for the exhaust of relatively clean air from a
wide range of commercial, industrial and institutional environments
such as manufacturing and assembly plants, ofce buildings, schools, hospitals, restaurants, athletic
facilities and many others.
