KBB57-57 Double Centrifugal Blowers

The KBB57-57 is a double centrifugal blower delivering 560 CFM of airflow in a rugged, field-proven design that performs reliably regardless of mounting orientation. Its baked powder finish provides excellent corrosion and impact resistance, making it suitable for demanding industrial environments where durability and consistent performance are essential.

The unit features UL/CSA Recognized ball-bearing motors available in both permanent split capacitor and shaded pole configurations, each equipped with automatic-reset thermal overload protection that safeguards against motor damage from sustained overheating. Kooltronic's motor engineering incorporates integral cooling through the blower's intake air, significantly extending motor life by minimizing temperature rise during continuous operation. Special permanent lubricants formulated to perform across an exceptionally broad temperature range from -20F to 250F ensure reliable operation in both extreme cold and high-heat applications.

All motors carry a Declaration of Conformity to applicable CE Standards, with the blower supplied with 12-inch power and ground leads for streamlined field installation. This combination of robust construction, advanced thermal management, and wide-temperature compatibility makes the KBB57-57 an ideal choice for critical cooling applications across diverse industrial settings.
