SDB Centrifugal Roof Exhaust 48 inch 25041 CFM Belt Drive 3 Phase SDB4

NOTE: Temperature rating up to 170°

These roof exhausters are used for the exhaust of relatively clean air from a wide range of commercial, industrial and institutional buildings such a manufacturing and assembly plants, office buildings, schools, hospitals, restaurants, athletic facilities and many others.

The non overloading centrifugal wheel with its higher static pressure capabilities makes this 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.

The aluminum exterior provides an attractive appearance. Belt drive results in lower operating RPM and sound levels, making the Model DB well suited to applications where quiet operation is important. Belt drive also permits easy performance adjustment when needed to balance the total ventilation system.
