(DB)
Downblast belt drive fans are designed to exhaust air up to 28,000 CFM, with high static pressure capability up to 1-1/4″. The belt drive results in lower operating RPM and sound levels, making the DB well suited to applications where quiet operation is important. Belt drives also permit 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 short duct runs and more efficient operation.
DB’s are primarily used for the exhaust of relatively clean air from a wide range of commercial, industrial and institutional environments.
