SDB Centrifugal Roof Exhaust 18 inch 3991 CFM Belt Drive SDB18RH1S

SDB belt drive fans are designed to exhaust air in high static pressure applications to 1-3/4". Belt drive results in lower operating RPM and sound levels, making the Model SDB well suited to applications where quiet operation is important. The non-overloading backward inclined wheel with its higher static pressure capability makes this unit suitable for either ducted or non-ducted applications. It's roof mounting permits location near the area to be ventilated, allowing short duct runs and more efficient 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, office buildings, schools, hospitals, restaurants, athletic facilities and many others.
